summ0ne's fix v12

[summ0ne]

**LATEST V12 REVISION**
http://www.ps2-scene.org/forums/showthread.php?t=37865

By soldering 2 resistors to the ps2 mainboard, we can limit the maximum power on the laser lens coils, protecting the ps2 from modchip bad sideeffects :-)

Diagram:
http://d-vices.com/summ0ne.jpg
Rst .............for 95% protection
Rst+Rsf ......for 100% protection

Theory:
http://d-vices.com/pstwo-fix.txt

Tips:
-Use 1/4W resistors because their pins are less stiff.
-Bend the pins so they align to the solderpoints = no strain on delicate
solderpoints.
-Don't heat the solder points for too long - you can burn the smd resistors.
-Dont let the pins be in contact with anything other than the solder points.
-Clean at the end with a q-tip + acetone.

Had any returns with this fix? Looks and sounds pretty good . . .

[summ0ne]

not personally.

other than some people having their ps2s die on the install table due to bad install, there has only been 1 report of a return out of 200+, we are looking into that, so we can verify if it is a false alarm or not.

[mikearama]

I've had one go bad on me, but it was indeed the install... bent the legs of the resistor too low, and didn't realize that it had made contact with a neighboring via (which I assume was a ground).

The other 22... all still in the field, no issues noted.

Hey summOne... I appreciate your efforts. Shame it required such opposition from some of our 'colleagues'.

[dudebig]

Same here, I have 10 so far, no complains, but still early because most of them are for christmas present.

[gums_work]

Has anyone done the mod successfully on a v12.2 board with the 1k8 resistor?

[davbere]

Good job Somone
I'll be trying your fix soon

[mikearama]

I installed my first 12.2 last night... the 1.8K is working fine. Through about 2 hours of play last night, my sons did not notice any problems. Course, now it's on to the customer for the real test.

great! so the 1.8k works after all :)

[psxgameshop]

My first V12.2 with SummOnes fix ( 1.8k ) and everything is ok.
Other 28 pices V12 ( 560 ohm ) are OK too !

[imaviet]

i used a 1/8W 1.8k OHM resistor on the v12.2. doesnt seem to work for me.

ill try again with a 1/4w or 1/2w resistor.

[bmwkang2000]

sounds great, more confirmation the greater the chance i'll be using this fix and a MI for the psTWO

[summ0ne]

try a 2k resistor

[imaviet]

try a 2k resistor
so the size of the resistor doesnt matter? when i installed the 1/8w 1.8k ohm, it doesnt read anything. not even oringinal ps2 games.

[digitsix]

I had my pstwo 12.2 modded by xteammods - they put in summ0ne's fix - not sure which resistor they used but I have been seriously BEATING on it since I got it, im talking 10+ hours a day between me and my roommate. Not one hop, skip or a jump. Any freezes that did happen, were not mechachon that i could tell because the reset feature was still working....

u look at ohms, not W. so install a 2k, does not matter how many W

[haniki]

Hi,
I have a PSTWO that have burn twice.
One with only the modchip and the other with
one of GRMOD fix (not the matrix fix)
Then today i put a summone fix with a 560 ohm cms resistor.

I will tell you if it works.

[imaviet]

i modified a v12.1 using infinity. i used the 1/4w 560ohm resistor. looks like dvd is working well but it doesnt read any of my cdr games. any solution to this? does the cd brand matter? if it does, i am using sony CDRs.

ok, after a couple more tries, it worked. i dont know y it wouldnt work before. maybe the system needs to warm up?? but thanks summon for the wonderful fix.

[Takashiii]

THE FIX:
Add a 3.9kohm to 4.3kohm resistor in parallel to focus 2u2 cap.
Add a 510ohm to 560ohm resistor in parallel to tracking 2u2 cap.

Sorry for sounding like a noob here. According to all the pictures provided I do not see any resistors installed on the Focus 2u2 cap point. So does that mean it's not necessary?

So, this fix is as simple as adding a correct resistor to the Tracking 2u2 cap point?

And also, excellent work on the fix. It's fantastic. :)

[tickford]

just apply the resistor to the tracking cct,nothing on the focus.:)

[Takashiii]

I apologize for my ignorant question above. I should of read thru everything first.

Now that I did, I manage to fry 3 system/lens in a row. :(

I have 3 datecode 4D system on my end all with the GH-xxx-71 mobo and I applied the correct resistors to them and yet it still fried my lens.

Here's what I made sure of:

I read thru the entire thread of the Old and continued version of the Slim PS2 problems. (Spent about 9 hours.)

Resistors were correct. 560R for 303, 1.8K for 683. I also made sure the color pattern were correct on these.

Taped all around the resistors made sure they made no contacts whatso ever. No metal parts were exposed in anyways.

On my 3rd system, I even used a brand new PStwo with no modchips to test with and the results were another dead lens. (It had a 683cap on it so I applied the 1.8k reisistor).

I'm beginning to think these 4D datecode machines. (GH-xxx-71) are different from the ones you guys are working with. :( Please shed some light.

Edit: I failed to also mention, when I fried the first PS2, I had the MI pic fix on. The 2nd and 3rd without.

[mollar]

I dont know what to belive anymore

Not sure which fix to try.

I have the foundmy fix but havent tried it because i dont want to fry anything.

Was thinking about trying this 560r resistor fix. mine are 303's


My board is the GH-035-11


Anyone have thoughts about this??


thanks

Well the truth was I was very very excited to find that someone's fix had such great success all over the forums. I went out and bought massive 560R, 1.8K resistors with forms of 1/4 and 1/2 w's. I was so sure that it was going to work but then all I have is now 3 dead ps2s. Notice all my PS2s are rather new and they are dated 4D with the GH-xxx-71 mobos.

If you read thru the thread carefully most of the people who are having success are using the 11, 21 or 31 series mobo. I have yet to see any success stories beyond that. Oh yes, all my mobos are GH-xxx-71's.

At this point, I'm affraid to try anything right now. :(

[darkmaster2]

can you take a picture of one (or all) of the installations, Its VERY strange that your laser is burning up in 3 consoles in a row.. I have done a few without trouble.

[Takashiii]

When I get back to work later I'll upload some pictures.

But you see, on my 3rd system. All I did was install Someone's fix on it and nothing else. No modchip, no fix, no nothing. Just a fresh out of the box system.

The caps read 683 so automatically I applied the 1.8k resistors on it. And then I made sure contacts were covered with electrical tape and tried an original game on it. I mean, it's pretty simple and striaght forward. Poop. It fried.

Initially I thought it was my install too. But after the 3rd system I did not think so anymore.

Note: I had modded over 50 slims and most are good but about 8 systems came back with the problem of freezing after 30minutes of game play. That is why I turned to someone's fix.

Someone, I hope you don't mind but I took the liberty and added you on my msn. Hoping you can shed some light. :(

[darkmaster2]

are you positive that the resistors you added are 1k8?
I have only applied the 560Ohm resistors myself.. has anyone else used the 1K8s?

looks like the system is having a problem now. after playing a dvd back-up game for about 15mins and i switch to another game, doesnt seem to load right. it would bring me to a gold cd screen or it just freeze during the loading part of the game. i am using ridata dvd's, burning at 4x.

[ideas_man69]

hey summ0ne..

been using ur fix and works a charm. just wondering, i mentioned on another forum that when playing gta:sa, the laser is constantly moving (you can hear it) and seems to have problems reading the disc. im using high quality TYG02 media and burnt at 2x - so media is not a problem. now you said to increase the resistance 5% to make the reading better:

- can you explain how you come to this conclusion?
- does it increasing it reduce the protection?
- why does vandrunen say that lowering it helped him?
- does reducing it reduce the protection?

560Ohm + 5% = 588Ohm yeah?

cheers.

[ShadowKnyght]

"imaviet" - May be down to the quality of the resistors being used - very cheap resistors have a large tolerance +/- 10% or more and as such your 560 ohm may have been to low or high to load some media.

And to my fellow ozzy - by increasing the value you reduce the current flow through the resistor thus you will reduce the protection a little but gain an increased ability to read troublesome media. GTA:SA sucks for lasers...

[Takashiii]

You see, this is the exact problem I'm having. And yes that is why I turned to someone's fix for help and now I have 3 dead PS2s :( Don't get me wrong, I'm by no means bashing someone's fix, I'm very desperate for help right now as I'm waiting for someone himself to speak out. :(

I decided to use someone's fix because of all the positive feedbacks I'm seeing from everyone in the forum. Has anyone else tried someone's fix with the new systems yet? :( [dated 4D with the GH-035-71 mobos]

And yes, I'm using the correct resistors. Like I mention in the other thread, I made sure the color stripes were correct and I also made sure they were matching resistors to the corresponding caps.

303 cap = 560R, (Not 560K, correct color stripes, 1/4w and 5% resistant)
683 cap = 1.8K, (Not 180R, correct color stripes, 1/4w and 5% resistant)
All very carefully taped around so contacts won't touch the ground.

I mean it's pretty straight forward, it doesn't get any easier then that. :(

[ideas_man69]

oh ok.. sweet as. is 5% a good number to chose? or should i bump it up a bit more.. maybe 20%? as i have the pic fix installed. the next resistor in e12 is a 680 ohm. i might have to use 2 in parallel.

[ShadowKnyght]

you can get 1% resistors in both "through hole" and SMT that have ranges inbetween the standard preferred values.

Takashiii - not suggesting you may have interpreted wrong but some times the colours in the colour codes are a bit hard to make out... have you used a multi-meter to check / confirm exactly what resistances they really are?

Just a note - I have not used this mod so can not help as to its suitability for various date codes and MB versions, or its' suitability as a solution at all. But it would be nice to believe that such a simple mod is all that is required.

[haniki]

Hi,
everybody, just to tell that the pstwo that i apply the fix, work since one week and 24/24h a day.
i will tell you in one month in what happen but it seems to work.

[ideas_man69]

oh ok.. but what im asking is - is it worth using a resisitor that's only 5% higher? some 560ohm resisitors already are 5% higher.

[mollar]

I went to radioshack and they didnt have a 560 resistor.

I bought the variety pack. I was thinking i could put some together to get 560.

Does it have to be exactly 560 ??

Who came up with that anyways?

In the pack is 10, 22, 33, 47, 100, 220, 330, 470

470+100=570
330+220=550
330+220+10=560

I dont really want to put 3 together but does it matter. I dont know

Any thoughts on this situation??

[imaviet]

"imaviet" - May be down to the quality of the resistors being used - very cheap resistors have a large tolerance +/- 10% or more and as such your 560 ohm may have been to low or high to load some media.

i ordered the 560ohm resistor from here http://www.circuitspecialists.com/prod.itml/icOid/2004

maybe i should try the one i bought from radioshack?

[mollar]

you got a 560 from radioshack?

The one i went to didnt have a 560

[OttawaMods.com]

@ mollar:
3 resistors in series is just fine.

[imaviet]

you got a 560 from radioshack?

The one i went to didnt have a 560

yeah, try another radioshack.

[mollar]

So i can put the resistors together to get 560 ...



What about the foundmy fix. Do i take it off or leave it on??

[hpolimar]

excuse me guys for this question.
the solution is just to apply 1 resistor only to that point?

[mollar]

@ mollar:
3 resistors in series is just fine.


I put the 3 resistors together and i get exactly 558 ohms


Is that good enough??


When i measured the seperatly they all added up to 579 ohms

When i soldered the 3 together i get 558 ohms

I put these together : 330+220+10


Maybe i should change the 10 to a 20

not sure what i should do

[Takashiii]

Guys no offense but it's pretty easy to order these online... they're only 10cents, why do you guys bother buying a bunch of these and create such a mess for yourself.

Viet has already provided a great link which they sell these at .01 cents each. What more do you guys want? :( Please keep this thread informative about the fix. Going off topic is why someone doens't even reply to this thread anymore. ;(

Shadowknight: Correct stripes of proper resistant or not, I mean, it won't be to the point where it fries the laser in 5 second right?

[mollar]

Why would i want to wait a week or more to order from somewhere when i can goto the store 5 minutes from here?? I dont think most people like to wait.

Its not hard to put them together.

All i asked is how accurate does it have to be. I have the 3 put together for 558 Ohms


Buy the way they are cents each but did you know you have to spend a min of $15 for an order ????

I dont think i need $15 worth of resistors or anything else from there....

[OttawaMods.com]

@ mollar:
558ohms is fine, remove the found my fix first, then test then put in the summone fix though if you found no problems wiht the foundmy fix why even bother changing?

[mollar]

there was a problem with the foundmy fix

According to there install diagram your suppose to have 37.5 Ohms on both after you install the 2 little black resistors

on one I got 37.3 Ohms which is good enough

but on the second one i only got 34.0 Ohms

thats where im stuck with that....

the original values without the foundmy fix are 39 and 35


Ill put the 560r fix on but just wondering if i should take the whole foundmy fix off. ( 4 parts all together ) (2 small ones, and 2 3-prong ones)


Would it do any good to leave the smd risistors on? (3 prong resistors to ground)

Thanks for the responses

[letsmod]

use one or the other, but your original value are no where near what they should to begin with. Both 303's are 30,000 ohms!!! that may be why your getting bad readings with foundmy fix. Are you sure your ohm meter is calibrated to Zero? are you measing the right point to get your values?

[mollar]

im using these points to measure in this diagram.

i tested with and without foundmys resistors

The red and blue points are the only ones ive been measuring..

The 303s test 30k each


Right now i took off all foundmy fix and put the 560r on

With the 560r on you dont get any reading between these two points in the diagram.

Takashiii, contact me on msn and u will send me some photos.
The two points on my fix are very sensitive - cause they are on an opamp input - are you sure that you have not grounded one - as the gnd region is right where the resistor pins meet the smd resistors?

[DJGAIT]

Just a thought of mine..........

Is it possible to put an adjustable pot instead of a resistor with a certain amount?

I'm looking at some defective lasers over here. Maybe I can lift the pots off and adjust them to the values specified and then put them in as Summone's fix.

Any thoughts about this?

[OttawaMods.com]

the POT's on the lasers are to control the power of the laser in reading media, the summone fix controls the resistance on the laser coils, more specifically the tracking coil. In other words why would you need to adjust the resistance on the tracking coil as such?

[ideas_man69]

instead of pulses like this:
IIII.IIII...........III..III............IIII.IIII. .........

It does this:
II...II...II...I....II...II...II........II...II... II...I....

mine seems to have problems reading some discs. if i increase the resistance to about 580-600ohm, will it be able to read a bit better?

ive got the pic fix if anything goes wrong.

[DJGAIT]

@radish

Maybe to have the fix working even with a more worn laser. Maybe (just a thought) when the laser worns out over time (how ya say that in english??), wich every laser does, the voltage for tracking, limited bij the 560 or 1.8k resistor, maybe too low to read well. Then you need a higher capacity limiting resistor. Then the variable POT resistor comes in handy.
Just thinking about the fix now but also in the future.

Any thoughts from Summone bout this?

Bij the way, modded mij first Pstwo (scph-70004 PAL) with 303 caps. Applied an 560 ohm 5% tolerance resistor. Alle fine for now here. Works great with the Infinity. Will stress test it to make sure it holds.

Bij the way: in the E12 scale on 4 band resistors you'll need: Green - Blue - Brown - Gold
Got mine from an old tape recorder. Has plenty of them inside ;)

Anyone who's working on this fix or any other. thanx a lot for your effords and willing to share the info.

Put the summ0ne fix in my ps2 last night. Wasn't sure I installed it right, but sure enough it crashed after I hit reset and walked away for a few minutes. When I came back my heart stopped for a moment while I unplugged it, but sure enough its working good as new after turning it back on

[anarchy2007]

I have done about 20 of the new slim-line (K Chassis) consoles with the Matrix Infinity and Matrix PIC12 fix. Not once could I get any of these consoles to turn off or to crash so that the Pic turns it off. I ran 1 console for over 35 Hours and changed disks very frequently, with another console I reset it about 100 times within 1 hour and still nothing. I have tried every thing and every way until today.

I accidently swapped point W with T and R with Q and what do you know every time I close the lid to read a disk (CD or DVD) the console turns off within a second. I tried with another console and it does the same. This could be a nice way to test all the diffirent v12 fixes that are out there.
Could someone please test this with the "Someone fix"

To summ0ne :

do you think that your fix will work in the V9/V10 also ?
i think your fix is better than that from romeo because of better
media reading...nevertheless i tried it in a v9 and reading is smooth and
flawlessly...but what will happen if the tracking coil counts down to 2 Ohm ???
does the 560 resistor still protect the LA 6508 to overheat ?

[madisonmods]

Had a 12.2 today that simply wouldn't work with 1.8k, nothing could be read. Tried a 2.2k and it's working fine. Am I compromising anything with 2.2k instead of 1.8? Also, is there a consensus on the lid switch? Are people removing this for extra security?

I am not sure u should use a 560 ohm, u should lower it till it is at the point of barely reading. I hope ure not connecting the resistor in parallel to the coil, but rather on the tracking opamp input.

Here are connection points for v9 and v10, u figure out the resistance :-)

Try a 2k resistor for extra safety.

The lid switch sounds great, people should test it and see if any crashes happen with this mod. If they dont, then it sure beats programming a pic.

[loy]

i wouldn't see how this has worked since the pstwo will still crash with the lid close emulating the effect of the switch being removed and bridged

thx i really wouldnt want my laser to burn because i have saved up my money for a long time to buy a pstwo. cuz my parents are jack asses they never buy me anything.
and i dont want it to go to waste. please help a brother out thanks

[ideas_man69]

Ok hey ... im new to the summ0nes fix. can anyone explain about this how to use it or install it in ur pstwo or whatever? i dont know what the hell to do. and wtf is OHM and all these stuff?
than you shouldn't be looking at this fix. im guessing you have ZERO soldering experience and if you want to save your ps2, take it to a pro.

[mikearama]

if you want to save your ps2, take it to a pro.

Preach on, brother.

[anarchy2007]

To summ0ne :

do you think that your fix will work in the V9/V10 also ?
i think your fix is better than that from romeo because of better
media reading...nevertheless i tried it in a v9 and reading is smooth and
flawlessly...but what will happen if the tracking coil counts down to 2 Ohm ???
does the 560 resistor still protect the LA 6508 to overheat ?


The only part of the Romeo mod that you need to do is the 5v Mod where you remove the 12vdc supply voltage and replace it with 5vdc. You won't have any dead coils or bad reading of certain media types.

[darkmaster2]

so the size of the resistor doesnt matter? when i installed the 1/8w 1.8k ohm, it doesnt read anything. not even oringinal ps2 games.

Im just wondering that when some people who are having trouble with 560 Ohm and 1.8K resistors, what does the ps2 do when it cant read the disk? does it go to red screen? I have one v12 going to red screen after it has been left on for a while... maybe i need to increase the resistor value?

[gums_work]

Mine didnt read anything at all, just acted like no disc inserted

[loy]

sounds like your laser is gone

[Gradius]

Done switch fix + resistor fix, everything is working like hell. :D

Not a single crash until now, after more 100h.

I am taking my pstwo to some one who is experienced with soldering.
im just asking DO i have to buy any of the stuff to do the summ0nes fix?

or do i just need a solder iron and wires or some shit i dont know??

can anyone tell me? ( in summ0nes explanation on how to do the summ0nes fix it is very confusing that is why i am asking you this thank you very much )

posted by: Lea

[masoud23]

just tell me what i need to get to do this fix list EVERYTHING

[NEWCASTLEmodchi]

1 x 560Ohm/1.8kOhm resistor (Total cost, about 4c)

If the installer you are taking it to is experienced they will know which resistor to apply

[EDEM]

I have problem with two v12 .First working 1 week .Second - 1 day :)
I use pic fix and 560R resistor.now cd working very nice ,but dvd - no.One little can work ,but only with very good quality silver media and very noise ....
Laser coils good.So , its problem with the laser crystal.
I think ,need fix the laser power problem.Or before installing chip ,need reduce laser power.

[masoud23]

Do i have to buy those seperately or is it just 1 item?

[mikearama]

You don't need both masoud... just need to figure out which resistor you need, either the 560 or the 1.8k.

[Parisno]

What wattage does the resistor need to be? I have some 0.6w (1% tollerance) resistors knocking about will these be enough or will I need a higher watt rating?

I have the same problem here. Also original DVD's won't boot :banghead: . CD's just fine Original and Backup. I modded with Matrix infinity. Also I have installed the PIC and Pupazzo Mod.

Does increasing the 560Ohm resistor help? The 2 SMD resistors are 30K.

Hope to hear something soon.

[tjuddi]

anyone tried 2k when 1.8 not working? i have one with 1.8 not reading(i can hear it struggle to focus) my supplier was out of 2.2k
But will send 2k s?

Well, the only thing that I can say for sure is that summone fix works very very very well in every pstwo, I have no one single ps2 back 20 units sold two weeks a go, but what can happend is that the 30k resistors are burned, you must be very carefull about that, I have burn a couple 68k just with a 12W iron and really short time of exposure, now I just solder a couple wires to the pad near the resistor and no more resistor burned, every ps2 works like a charm, I think you must change the 30k resistors, do not use smd resistor, you can burned again, and use the 560r resistor for summone fix, it is the best fix that I have seen.

[Gradius]

Nice to hear that. Of course, a lot people burn that little smd resistors, they're really weak to excess heat.

[biggy7]

im attempting to source these resistors from uk, ive been into the rs wesbite and found this:

Description Resistor, carbon film, high stab, 0.5W, 5%, 1k8
RS Stock No. 132-551
Manufacturer TYCO ELECTRONICS
Part No. 41623932-4

that ok?

[GTZ]

Sounds ok for Ver12.1 but u need 560R for Ver12.
Also, see if u can find 1/4 watt instead of 1/2 watt, 1/4 are a bit smaller but 1/2 will still work.

Cheers,

Hi,

I now know the problem, but after frying the laser :cry: One of the 30k resistors didn't touch the PCB pad anymore!! I also soldered the 560R resistor directly to the 30K SMD resistors and I probably broke the connection to the PCB pad in the procces :banghead:

So, there went my profit and I bought a other laserunit and installed the 560R resistor also with two thin wires, and everything works flawless. DVD-R/DVD+R/CD-R....

I'am trying now to repair the coils of the laserunit, its just one side so I hope I get lucky :-pray: I'll let you guys know if its worth the try.

[Ferid]

Gonna do my first v12 with a Ripper3.1. Do you recommend doing both the pic fix and summ0ne fix? Or is the Summ0ne fix enough?

Try maplins. They do a 0.6W metal film resister with 1% tolerance in many ohm values. I buy mine from there when i run out of my usual ones, although at Maplins they're abit steep, i mean 7p for a resister :mad:

[qwm]

If you gonna do matrix-fix (diode+pic) and summOne together, you must test another value for resistor, because the signal goes too weak with diodos+resistor....

[henno]

Thanks For The Summone Fix , Works 100% With The Ghost2.
Summ Times The Easiest Things Are The Best . Cheers Henno.

Resistor Specs Are Not That Critical Apart From The Actual Resistace Value Itself. 5% Tolerance Will Be Fine
Don't Order Them From Exy Companies. Just Go To Your Local Fixit Store / Tv Repairer /what Ever If They Have Them They Will Probly Give You A Couple For Nicks Or Point You In The Right Direction. .5 Or .25 Watt O.k. Just Make Sure You Have The Correct Value.
If You Are Not Into Electronics . Get A Cheap Multimeter & Check The Value With That. It Will Save A Lot Of Head Aches & Fried Units.

[EDEM]

my 30k resistors all ok.cd-r works very good. DVD- no (clicking)

[Prelude]

EDEM: i have the same problem... how about original dvd does it work?

my laser always clicks / no activity when playing dvd-r... all good media

[ivandiz]

I might have the same problem as you, Prelude.
I have a v12 with Infinity v1.38 installed & SummOne's 1.8k resistor fix (68k resistors). Originals play fine & CD-R backups work fine. My DVD-R backup games (that work fine in my v9 PS2) are not working. They'll get past the Playstation2 logo screen & then either freeze at a loading screen or just have a black screen.
Any advise would be appreciated. Thanks in advance.

[T07N]

my 30k resistors all ok.cd-r works very good. DVD- no (clicking)

You used a 30,000 ohms resistor?

[moja]

Holy crap, do you have polished discs?

[Ferid]

Finished my first v12. Put in a Ripper3.1 and did the summ0ne's fix. Let's hope it stays oke :)

[Pikachu]

u look at ohms, not W. so install a 2k, does not matter how many W

Oddly enough, I am having the same problem. I have not tried the 2k ohm resistor yet. I will double check. But imaviet has the same problem as me. When i wired up your fix, the dvd would not read anything. It's as if there was never a disc in the system. If someone has success with the 1.8k, please post up. Thanks.

[congcongbgv]

I don't know if I do succeed or not with the 1.8k ohm but I hope summOne could help me on this, this is a little detail about my story on the PStwo with his fix: I got 2 PStwo and they are the same story so I only tell one story. I have a 70012 US with the Magic V Kx installed. I didn't measure the tracking coil before I install the modchip. After I mod them, tested DVD original, DVD back up, CD back up, PSX original, PSX backup all worked great. Then after that I open them out and and measure the two places of the tracking coil, where you will solder the 1.8k ohm resistor, they read ~1,889, I am not sure if it is suppose to be around that number, sorry I am a noob, really one, lol. Anyway I applied the 1.8k and measured again, the meter read ~.889. The 1.8k I bought at Fry's Electronic (outpost is the name for online), they printed on the label like this "1.8k ohm, 1/2 watt flameproof resistor" with the price of 5 in a pack for $.99 cents. Every single disc I tested before the fix still worked fine after installed the fix. I though if I install the 1.8k then it should decrease 1.8k but the original # is ~1,889 and after the 1.8k is ~.889 which decreased 1k in basic math. I have no idea. Since some of you with fantastic input on the fix, this is something I want to add in about the 1.8k ohm fix. I hope summOne has sometimes to have an idea about my story since his time is valuable.

There is no use really in measuring resistance on those points since there are a lot of nonlinear elements there so you might get different values using different multimeters and ranges. But if it showed 1.8k before applying 1.8k in parallel, it should show half that afterwards :-)

And since your machine reads all media afterwards, that is one succesfull 1.8k resistor applied - there you go, Pikachu.

[Pikachu]

summ0ne, regarding the resistor, I had tested the resistor as I had one 1.5kk ohm resistor + three 100 ohm resistors to net me a 1.8kohm resistor. It checked out to 1.77k ohms. But this did not work in my ps2. I added two more 100 ohm resistors to bump it up to 2k like you said in an earlier post and now it works like a charm. Lets hope it holds up. Thanks for all your help, summ0ne.

[Ferid]

Summ0ne, do you think your fix is enough? Or would I need to do the pic fix also?

[summ0ne]

so far i have had 1 pstwo out of 40 that stopped reading DVDR. All had my fix only.
So i will call that bad one tolerance and declare a 100% succes :D

[hpolimar]

just one question: what are model codes of v12 and v12.2 ?

[xcode]

20 more done it, no one back

a friend of mine, 80 total, no one back
:cool: :cool: :cool: :cool: :cool:

thanks sommeone

[just wondering]

hi , i've done 4 of the new u.k slimline ps2's theres two board model number 32 and 35, the two 32 boards , no problems , but the two 35 boards , just instantly stopped working as soon as the machine was switched on with the mod and sommeones fix.

but the two 32's where fine ? the two 35's gave a smell of burning ......i've use apple 70k chips , any help ?

[Pikachu]

I had summ0ne's fix in my pstwo and I recently experienced a mechacon crash. Does the fix do anything to protect against this? I reset the pstwo by pulling the power and hooking it back up and it worked fine again.

[SilveryDragon]

Had my first mecacon crash last night, only perhaps 5 secs as I realised reset wasnt doign anything and black screen on load, so I yanked cable and plugged back in, fine so far since. How long does the laser take to burn on an unprotected one, anyway? and has anyone yet actually done a proper stress test over a period of time in crashed state?

[psxgameshop]

HI,

OK, my very first with dead laser with summones fix and MI. From 50+ with MI and summones fix, and 10+ with Neo bright and summones fix, this is the first one that cant read DVDR anymore. CD reading is fine. Coils are around 5 Ohm.

regards,
psxgameshop

[SilveryDragon]

Did it read dvd's after modding, or stop immiedietly?

[psxgameshop]

No, PStwo was fine. It was moded and sold 10 days ago. The problem appeared yesterday.

regards,
psxgameshop

[SilveryDragon]

Interesting. perhaps someone should measure coils at beginning of mod, and then check them regularly, to see if there is any degradation over time? say every week or so of heavy usage. Would be interesting to know, and set minds at rest. Through I guess such a test would require a control unmodded unit too, to account for any natural degradation.. hmm. I guess it would be hard to prove what was cause unless it was a fairly large amount.

[summ0ne]

I had a return just like that.

maybe adding a PIC would stop it (as probbably some other part went, not the coils).

but the damage might happen during normal usage, so i dont even bother.

At 100$ pure profit per install, that drains my profits by less 1% - given that i sell the mobo for 60$, the joypad for 30$ and the supply for 25$. B)

and i would pay 1% anytime for a load off my mind ;-)

Can you explain this a little better? I'm thinking if it's a customers machine that blows, you would have to re-imburse them somehow or work something out so that you can part their machine out. They've already dropped ~$150 for the PSTwo and another $100 for the modchip, I'm sure they wouldn't be willing to just give you their broken PS2 and go out and buy another one for you to mod.

How do the rest of you deal with these blown PS2s (v9,v10 & now v12s) when a customer brings them back?

Just curious...

[xcode]

I´m doing pupazzo fix too, no one back 45 ps2 total, but I´m adding matrix fix pic from tomorrow to see what happends

[summ0ne]

i fix it or give them a new premod within 2h.

i give out 3month warranties on all my mods.

(150-25-30-61)/5/100=0.7%

thats 70c per install - cheaper than the PIC, letalone its preparation+application ;-)

still, its not verified that a pic prevents that

[psxgameshop]

SummOne you are right, I have installed more then 60 pstwo units and this is the only one with problem. So I dont care about it. My customer will have brand new laser tomorrow.

regards,
psxgameshop

[Pikachu]

summ0ne:

There something called a neo-fix xii that looks like a pic fix with diodes. Is this your resistor fix + a pic fix? Or something else?

[summ0ne]

no, this is the diode fix + pic fix.

you can install:
- my fix on top of that fix
- my fix + only the pic part of that fix, break off the diodes part (safest)
- just my fix :P

[Pikachu]

Also does your fix do anything to protect against the mechacon crash? I just got one last night. I reset it by unplugging the power and it started back up fine.

[SilveryDragon]

No, resistor fix wont stop the crashes, just protect the system from frying during them

no adding pic not stop it
v12s sent out here with mfd (diode fix) plus pic chip programed myself all tested (wired to ground)mainly crystals and few infinitity

4 returned (1-2weeks later) ciols are fine
1st machine just black screens, removed pic all is fine, either resister died or pic , never bothered to check lets move on

other 3 are what we need to prove piont
cd cdr worked perfect, dvd woould either activate pic chip imeadiately laser sees it, or just sit there act as if cant read dvd ( actually everytime this happening mchanon crashed, but pic not turned off ps2) thes lasers were tried in new ps2, same problem, new laser on any of there mobo worked fine
every 1 of these is a 12.0 303 resisters and origanal laser
12.1 i take it as 683 slightly diff laser ( ie caps/resisters on copper square u can see when u open the lid to the dvd drive
12.2 gho35 totally diff laser and has small "b" after the scph no.

ps the way to turn the ps2 off when mchahon had crashed was to release a tray switch, ps2 turned off immeadiatly then as if it had remember my pushes of the reset , tested many times always the same,POWER NOT NEEDED PULLING OUT, can anyone else test this

diodes seems to have done the ciol problems , either extra load dameged the dvd diode or pic chip caused it

so i now started fitting just summone fix

other possability i hope the answer is we have stopped the ciols burning, odd few12.0 lasers will die naturally on dvd side, this has been fixed on the 12.1(slightly diff laser) or 12.2 (totaly dif laser)

had v9 in today, for repair NO CHIP INSTALLED, NOT READING I WAS TOLD la i thought, well cdr worked dvd didnt, dvd side is dead as a dodo, ciols are ok, pop diff laser in (400c) works perfect

obviously pots tried nothing can be got out these lasers on dvd side

really we need someone who knows about lasers to take a look at these ones were dvd is dieing

also has anyone noted wierd pot settings on the slim v12s, i leave a few of u to meassure and post your findings

So basically if mechacon is crashing, just pop the lid open? I tried that i think and it didn't work. I'll try it again when it happens. :chinscrat

[GTZ]

If it's the one on the right (12.1) you should be using 1.8k resistors instead of 560R's.

Cheers,
GTZ

[GTZ]

Yep, if 1.8's don't work well, summOne recommends going to 2k.

Cheers,
GTZ

[swordfish]

I've found out that values between 1.8K and 2K ohm work best. I usually use 1850 ohm and not a single disc reading issue.

swordfish

[swordfish]

davbere: check to see if the onboard resistors are still good. Sometimes too much heat can damage them

swordfish

[swordfish]

Values seem to check out ok.

Have you tried to boot a game w/o the resistor fix? if the same results occur, I would say the coils might be damaged. Check the resistance of the coils while you're at it, both focus and tracking.

swordfish

[Pikachu]

The 1.8k resistor didn't do it for me. I had to use a 2k resistor and it worked fine.

[psxgameshop]

Second pstwo is dead:( In only 2 days, this is the second pstwo with dead laser. This one was with neobright and SummOnes fix. Moded and sold 4 days ago. Both CD/DVD are not working. I will check coils tomorrow.

regards,
psxgameshop

[psxgameshop]

OK, Focus couls are dead ( 2.6 Ohm ) tracking coils are fine 6.0 Ohm. What do you thing about using diode fix on focus coils ?

regards,
psxgameshop

[GTZ]

I think resistors if anything would be better on focus coil resisitors. But I thought summOne discarded the need to protect them. His original diagram had them protected with 3k9-4k3 resistors. Correct me if I'm wrong but I think this is the first occurence of a fried focus coil while the tracking was protected with summOne fix.



Regards,
GTZ

[psxgameshop]

Yes GTZ, you are right. From now on, I will protect focus coils too. I will use first SummOnes fix - protection on focus and tracking.

regards,
psxgameshop

[congcongbgv]

on the diagram its said 3k9-4k3 for the focus coil, is that measure in ohm also as the tracking ? how about if the places have 683 resistor, what range will be apply ? I mean for the focus, I aldready knew about the 560 and 1k8-2k for the tracking

[xcode]

:dance:
60 pstwo gone, all summ0ne fix no one back :dance:

The focus resistors are the same on both 12 and 12.1's.

[gordy_au]

Thanks for your work summ0ne. Had my first dead one with a neo fix installed. I knew the diode fix was useless but i thought the pic would do its job. Not the case.

Installed your fix and its back to normal (after laser replacement :( )

Now for the big test tonight.

[psxgameshop]

Replaced the laser and tried to protect focus coils too, but cd is not spinning ( 4k3 on focus coils, and 560 on tracking coils ) anymore. Without focus protection everything was ok.

regards,
psxgameshop

[summ0ne]

Ok, here are some news from the stuff i discovered yesterday:

It is true that the tracking coils are always the ones that blow in an unfixed console and the thing stops reading.

But when you protect the tracking coils, the console operates for a long enough time for the focus coils also to start deteriorating.

The two consoles that came back had their focus cols resistance 1 ohm lower. They barely read CDs, but not DVDs. So i added a 4k3 on the focus input. And they read nothing until i replaced the laser with a 100% good laser.
That is proof that the focus coils were in such bad shape already that they could not operate at a lower voltage.

so heres the deal:
If u wand 95% protection apply resistor to tracking only
if u want 100?% protection, apply both.

All of u who choose both - be sure to report if 4k3 is a good pick.
warning: if u apply 4k3 and your console already has questionable focus coils, it will not read. So for now report only bran new console results.

Later i will update my first post in this thread so it is more clear and up to date :-)

[Shapes]

I'll be modding mine today or tomorow. Planning on adding resistors on both tracking and focus coils. Will let you know how it works in soon as 'tis done. :D

~cheers

PS its a brand new..well almost (2 weeks old) PStwo v12.

Heh, it hasnt been tarnished yet. :D Will be getting a chip and the resistors soon as they come in though. :evilgrin:

SummOne:

When I swap dead laser (dead focus coils) with brand new - from a brand new console and put 4k3 resistor on focus coils, the cd is not spinning. Is 4k3 real value for protection, or we may use 3k9 instead ?

[roro]

how come the 1k8 was changed to 2k?

[Shapes]

how come the 1k8 was changed to 2k?

It hasn't, its just that 1.8k hasn't worked for everyone, so they went 2k, which seems to do the trick.

does the cd spin without the resistor?
try a 4k7

[psxgameshop]

Yes, without resistor everything was normal. I can't try 4k7, becaouse I already deliver the console.

I installed a DM$4 Pro in my brand new pstwo with both your fixes. Lets see if it holds up. Now if I could only figure out why my pstwo is overheating. My pstwo warms up and nothing comes up anymore. Can't seem to figure out why. Flakey chip perhaps....

[congcongbgv]

I've heard it's better for us to unplug the power of the PStwo after we are no longer play will help the system. Sorry if this is old new.

Did you install a 4.3k on the focus coils aswell?

[darkmaster2]

I just did my first 2 consoles with the 1K8 resistors. All is going smoothly :dance:

I left one of them on all night just to make sure and this morning it was still goin strong (even though it was quite hot)

the moral of the story is.. 1k8 resistors are working fine for me! :D

[congcongbgv]

I totally did 1 Magic V Kx no fix and 3 Magic V Kx w/ summOne's fix and Pupazzo's fix together all using 1.8k resistor, running great. Last night I also try a fix on the focus using 1.8k + 1.8k + 560 = 4k160 (that are the only resistor I have heehehe) without any success. The disc barely spin. So I took the fix out and everything is back to normal. May be not enough because it only 4k1 but not 4k7 as summOne recommended. I don't know, it might not even spin if I put a 4k7 in there. Will find some 4k7 and try it.

[ShadowKnyght]

ummm - I don't think you need to add the 4k7 resistors - I thought Summ0ne dropped that from his suggestions...

Oh and darkmaster - yeah - these little buggers draw 5.3A and have no real air flow - so yes they would get pretty damn hot when left for long periods of time!!!

[congcongbgv]

to ShadowKnyght = see post #163

everyone, I just add only the 4.7k fix and the system is running good while testing. I will mod it with Magic V Kx again (that is the only one I have, 1 left) and a 1.8k on the 683 tracking and 4.7k on the focus. Will see how it will end up matter in time.

[ShadowKnyght]

bloody threads get to long... ;)

May have to start a summary thread that is locked to questions and only displays the latest suggested fixes...

[bobcat]

great idea i,ve started one off.

[peccione]

Dear all,
I am in trouble with summone fix...... Thats the story....
I proceed soldering two little wires on both the 303 cap of the tracking coil and I solder a pot set to 560ohm to the wires. I used a 30W iron and the soldering was fast and clean..... I'am neither an expert nor a newbie in soldering but I really made my best for those two connection.

I tried the pstwo no-mod with an originale ps2 game in and only the browser appeared.
I changed the resistor value and nothing changed....
Finally I disconnected the resistor opening the circuit and still nothing..... The disc seems to start spinning and stops a little after switching on the pstwo....

Then I removed everything (wires and so on) and the PStwo starts working again.

What could be happened??

I found a 560 Ohm resistor to apply instead of the pot. I will try the fix again tonight but I am scared about soldering the resistor directly to the 303cap.....

Any suggestion appreciated
thank you

[congcongbgv]

if your resistor is too big then you don't have to solder directly to the 303 becaus doing so might damage it, use the wire to help in conecting

[hpolimar]

i've done 2 v12.1 using 1 resistor of 1.8k and 2 of 2.2k (total 4.4k). They seems to work fine

[OttawaMods.com]

cut the legs of the resistor short and solder 30 gauge wire on to it. Also cover you resistor in electrical tape to ensure no shorts.

[NEWCASTLEmodchi]

Perhaps also use a lower wattage iron. 30W could fry a component

[OttawaMods.com]

I use 40w with my lead free solder :p.

[ideas_man69]

lead free solder is not designed to be combined with lead solder (which is what the ps2 uses) - dont be surprised if the soldering comes apart.

[peccione]

hi,
I haven't soldered the 560ohm resistor yet.
Looking at some pics of succesful modding I compared the my solders (the ones I made to solder two wires and a pot to the 303 cap of the tracking coil) to those reported on the pictures..... mine were more little and sharp.... maybe too much.... I really don't know.

I will try to reduce the wattage of my iron twisting a stainless steel 1 mm diameter wire on the tip of my iron and try to solder with the wire....

Are you sure there are not other soldering points for the summone fix but the two 303 caps?

If this fix works by dispersing power from the coil to the resistor why it is not fixed directly across the coil? If I'm not wrong there are two points were the coil resistor is measured easily accessible. In this way maybe the OP amp should work far from saturation......

bye

[TRABEL]

installed new ps2 with both fix's , 560 and 4.7k with ripper chip .
ps2 working well for now , playing GTA SA for about 2 hours ... seems o.k , had few freez , and once disk error but for a sec and back to game .
not sure if m disk or ...
using memorex i think burned x1.

Just Installed v12 Matrix Inf.
Used 2k and 4.3k fix .
All works ok , but Scratched DVD-R Disks just not works...
Media like Ritek DVD-R works 100% .

In this instance, would the 1.8k resistor work better? It may allow the scratched discs to boot (although it's probably best that it won't boot them - as it would be tougher on the laser anyway).

[summ0ne]

No, the greater resistance - the faster it reads.
BUT scratched does not have a thing to do with it.

My fix has the same effect on original pressed media as on scratched copys.
If any disc reads, leave the fix alone!

Scratched OR mint condition - the only thing decreasing the fix is gonna help do = burn your coils.

[modicullus]

Thanks for clearing that up summ0ne. I guess I had it backwards...

[OttawaMods.com]

1.8k are for v12.2's with 683 resistors not 303's. If 560 doesnt work thoguh try upping the resistance to 580 or 600 ohms. If 1.8k doesnt work on a v12.2 then try upping it to 2k or 2.2k.

[loy]

i hear theres a new addition to your fix with a 4.3 k resistor why not post pictures? I've seen the extra add on but i think u'd liek to post hte picture though

[modicullus]

He already did. It's actually one of his original pics - with the 4.3k resistor on the tracking coil (or the focus coil? - whichever...). They've only changed the 1.8k resistor to a 2k resistor.

It seems as though it has since been determined that it may be best to add resistors to both the tracking & focus coils (like summ0ne had originally thought).

[Durzel]

Just thought I'd chip in and say that I have a PStwo that has suffered two mechacon failures....

The first one occured when I switched on the PStwo after it had been on standby (red LED) for several hours. PStwo booted to "no disc inserted" browser, reset button was unresponsive, and laser burnt out a few seconds later (even after power had been pulled). This was on a stock PStwo with Matrix Infinity installed - no fixes applied.

1 new laser later, with summ0ne's fix (only the tracking coil fix). I get a mechacon crash again - exactly the same circumstances, PStwo switched on after several hours sat on standby, boots to menu even with disc inserted, reset button unresponsive, etc. The only difference this time is that the laser didn't burn out, and after physically pulling the power out and putting it back in the PStwo booted fine, and continues to play DVD-R backups no problem.

In summary - summ0ne kicks ass.

[masoud23]

some body told me that i needed a 1 x 560Ohm/1.8kOhm resistor for the summ0nes fix? is that true? or do i just need One Resistor if so which one?
(i have a v12.2 pstwo) is a 560 k ohm and a 1.8kohm resistor the same or what?

[masoud23]

and what does summ0ne mean when he says :
Add a 3.9kohm to 4.3kohm resistor in parallel to focus 2u2 cap.
Add a 510ohm to 560ohm resistor in parallel to tracking 2u2 cap.??

And Focus and tracking what are those? explain plz. are the something inside the pstwo? and if some one could give me a picture of What the Focus and tracking 2u2 cap are? plzz thanks

[modicullus]

see four posts up ^

[masoud23]

CAN Anybody give me their msn or AIM Screen name PLease so you can explain to me and awnser my questions faster plz thanks

start at page 1 and read trough it,s all there wt you need to know.

[congcongbgv]

the word please doesn't please others to give you the answer for your question because we can't. Simply your answer will be found in all the posts along. Just read, all, from the beginning, yes from the BEGINNING.

[cakcetin]

Well I installed in virgin pstwo mars pro,neofixII only 12c508, 303 resistor 560ohm and 4k3ohm...For the present not a problem and Summone what is your suggestion about it?
Can I give this multi fix to customer?
I try winning eleven8,Gta SA by many reset....
Thank you very much for this simple and free fix ;-)

[cakcetin]

Ok,ps2 when tried load game failed or too long load time in hk gold disk??Pstwo read DVD-R disk perfect.I will remove 4K3 resistor.I cannot try cd-r.
Regards.

[summ0ne]

after removing the 4k3 - does it work?

[cakcetin]

Yes a short time ago I remove 4k3 now working fine...(long load time finished)
What is your suggetion now?

[psxgameshop]

I'm using 560 Ohm ( 1.8 kohm ) on tracking and 4.7 kohm on focus. Working very good. The laser is working much smoother then without fix. As I said before I will use SummOne's fix as a final solution.

regards,
psxgameshop

[cakcetin]

Hmm; I don't have 4k7 for now but I will try it,but psx gameshop do you try hk gold-silver?Or you are try only dvd-r?Because dvd-r worked perfect with 4k3.

[Shapes]

Ok,ps2 when tried load game failed or too long load time in hk gold disk??Pstwo read DVD-R disk perfect.I will remove 4K3 resistor.I cannot try cd-r.

Add a 4.7k to the focus coils. Mine did exactly same thing with 4.3k, but when replaced with a 4.7k works like a charm.

Btw with the neofix, did you cut T1/2 and F1/2 just soldering J,K,5v and GRND?

~cherrs

[cakcetin]

Ok,thanks i will try it.Look at the picture for neofixii.

[psxgameshop]

Cakcetin:

I don't have HK gold, I have only one Chinese silver and it works perfect. I'm using Verbatim DVD-R recorded at 4x speed on NEC/Pioneer recorders

[minos197]

Sorry guys but I am confused.Why after 14 pages do I still see the 4k3 resistor be used?I thought it was the in initial fix and is not really needed.Am I wrong?I have been using only the tracing fix but shoud I start applying the focus too???Is there any particular reason that it is needed??

[psxgameshop]

From 80+ PSTwo consoles with different modchips and SummOne's fix I have only 2 returns with dead FOCUS coils, while tracking coils were protected with the resistor, focus coils were left unprotected, so I deside to protect them too.

regards,
psxgameshop

[SlinkyDink]

I agree that the original post needs some clarification.

In the attachments there is conflicting information on the diagrams: One says to use the 4.3K resistor, another says not, one says 1.8K on tracking, and yet another says 2K on tracking.

Yes I know that the difference is explained through the thread, but it would be best to remove the outdated diagrams and explain the different approaches to the same mod (such as the optional focus coil protection, and the level of resistance used is a compromise between safety and possible disc readability)

[eMaNoN]

does the resistor use in here, CAN BE BOUGHT AT RADIOSHACK?
(cuz i know taht radioshack is selling resistor)

need help with, can pinpoint where i can get this thing...

[loy]

yes u can use the ones at radioshack

[eMaNoN]

loy,
can u give me a link which 1 i should use...?

[summ0ne]

first post edited, all info updated and clear :-)

[congcongbgv]

thanks summOne, short and effective (I mean the 1st post after edited) :lol:

[psxgameshop]

SummOne:

I have a problem with one of those pstwo with burned focus coils. There is also a burned 303 focus resistor. I don't have 30 kohm resistor, so I put 31 kohm resistor instead. Everything is ok, but when I try to protect focus coils with resistor, the console can't read any disc. I tried this values 3k9, 4k3, 4k7, but no sucess. Without protection everything is fine. Should I try something under 3k9 ?

regards,
psxgameshop

[summ0ne]

hmmm.....

I did a few with 4k3 and they gave me no probs.

try replacing both focus resistors with 31kohm

[psxgameshop]

I will, if no sucess then I will left focus coils unprotected again.

best regards,
psxgameshop

[cakcetin]

Today I apply 4k7; now pstwo read everything flawless...
I hope coils not burn.
Here all modders install diode fix and give to people 1 year warranty;I can't believe it but customers trust to them.

[congcongbgv]

1 whole year ? that's a darn of time

[tjtownz]

SomeOne's fix is working great in my latest modified v12.2

Had to double the 1k resistors since they werent availabe in my area.

Thanks to SomeOne for his dedication to the scene.

Picture below is of my personal PSTwo I just modded, im keeping this one for myself. Case mods and lights soon to come.

[eMaNoN]

heres what i found on radioshack (resistor):
heres what available there:
1/4 watts 4.7k ohm
1/2 watts 560 ohm (no 1/4 available, only 1/2)
1/2 watts 2.0k ohm (no 1/4 available, only 1/2)

so 1/2 watts is ok right...?
correct me if im wrong...

[OttawaMods.com]

any wattage is ok pretty much.

[T07N]

Get 1/4 watts. Get the 1k ohms pack and connect two 1k resistor together to make the 2k resistor.

They have 560ohms, only in 1/2 watts but that's ok.

[tjtownz]

Thats what I did in the picture above.

The Radio Shack in town doesnt carry much, but they had a combination pack of 1/4 wat resistors. The werent any 2k resistors, so I just linked two 1k resistors together.

I always run 30awg wire to the resistor and then connect them to the board.

You can see in the photo a few posts above this one.

[ShadowKnyght]

My suggestion - use SMT 1206 sized resistors they fit perfectly between the two points in the 560 ohm / 2k location and with a neat wire added - it also fits nicely in the 4k7 position.

See the attached picture for an example of it applied professionally with SMT parts :D

[mikearama]

Shadow... very nice work, indeed. Cleanest summ0ne I've seen to date.

[wmb88]

Better use some tape to insulate the ground then solder the resistors. Otherwise the result would be very terrible if one of the resistor gets short to the ground.

[imaviet]

seem like i am the only one who is having problems with the someone fix. i modded about 10 v12 consoles and only 3 of them were successful. i used the ripper 4 mod chip and infinity for the rest. the problem i am having is i can only play for 15mins and then it starts skipping and if i reset it, it just freezes in the beginning. and 2 of them says some like "tray is open" when i play for about 10mins. for the v12.0 i used 560ohm resistors. for the 12.1 i used 1.8k ohm resis. then changed to 2.2k ohm resis. and still have the same problem. does it have anythign to do with my dvdrs? i use ridata dvdrs. any tips you guys could give me? perhaps post up some close up pics of how you mod your v12s? thankss

[NEWCASTLEmodchi]

Some PStwo's that I have done using only the tracking resistor worked fine except for when using one of my PSX HK -Silvers (Tekken 3) - the intro movie skips. However, I've since applied the focus coil fix to these systems and now Tekken 3 reads perfectly and I think DVD-R games load better as well! I used 4k3 and had no trouble at all. Both were v12.0 machines

Maybe you should post some pics of your summ0ne's installs. It would give us a better idea of what may be causing the problem.

[OttawaMods.com]

@imaviet: try installing a 4.3k-4.7k resistor on the focus. I just got 4.6k 5% resistors to be safe so i dont gotta buy a bunch of different kinds.

[ShadowKnyght]

Better use some tape to insulate the ground then solder the resistors. Otherwise the result would be very terrible if one of the resistor gets short to the ground.

hahaha :rolleyes: (sorry - lack of sleep)... unless I was to scratch the thick conformal coating off of the ground plane by accident, there is no need to add any electrical tape with the way I have done it!

The leaded or through hole resistors - yes you do need to use it because there is more chance of them touching a via or another component and even possibly the grounded shield plate - but when using SMT resistors there is no need.

You also avoid placing stress on the week metal edge of the existing 0805 sized (303) resistors. It is far to easy with rigid legs of a through hole resistor to pull the edge of one of these off.

The coating is ok when nothing on top of it. We all know what's the purpose of coating on PCB's? It can be scratched off easily by a heated sharp iron tip. Can't believe it was a suggestion from an EE, who looked like to set an example to forum members with different levels of soldering skill.
The reason I post here about the insulation tape is just I don't want other people to suffer from the same mistake I have experienced. Shadow, do you know what would be the result in case one of those solder points gets short to the GND?

[iuli_psx]

hi everyone! i have a theory who work to me. i have a v12 with ripper IV+fix1+diodes. i moded from the begining of decembre. every time when i want to play a game or watch divx movie (most time i watch movie), turn on console with cdrom cover open. after 2 sec i close the cover and all is fine. i make this even i want to reset console, first i open cover, reset and after 2 sec close cover. most lens burn when you start or reset console and if you have cover openn no any power goes to lens but you give time to pic to power on and work. maybe some guys are interested to test my ideea and tell everybody if is good.

i know this is newbie question but um... can anyone give me a picture of where to solder the resistors in the pstwo???

[loy]

look on the first post

[masoud23]

i need a picture that has already been done... close up... ( and damn howd u reply so fast )

[biggy7]

damn, just noticed that the pic has changed to 2K Ohm resistors, and ive just received a load of 1.8K ohms :(

is the 2K ohm absolutely necessary? or will the 1.8K ohm suffice?

[masoud23]

oh damn nvm the first page changed? wtf howd they do that?

[masoud23]

its so sexy..

[AT6767]

is the 4.3 on focus good or does it HAVE to be 4.7 cause im about to do v12 and dunno if i should the 4.3 or 4.7

yes, im pretty sure i didnt lose any cool pads. this is not the only one that does that. after 15mins, it jsut freezes on burnned games but orginal games, it reads well.

[T07N]

I'm having trouble with 1/4 watt 4.7k ohms resistor... It's not working. I had to take it off for the pstwo to read dvd or cd. Anyone having the same problem? Couldn't find any 4.3k at my radioshack.

[summ0ne]

can you measure the resistor value?

if you bought 20% tolerance resistors, you might have stumbled onto a 4k7 resitor that measures even below 4.0k :\

[T07N]

It was 5% tolerance. 4.6k when I measured it.

This is a media problem every other time I've seen it. Something to do with Summone's fix. If you haven't already, try Ritek, Verbatim or Taiyo Yuden and it probably won't lock up...

[OttawaMods.com]

@AT6767: If you've read the post you'd see that 4.3k is reccomended and if that doesnt work then go as high as 4.7k

[Robot]

OK iv got the same problem as tony and 2 ps2 slims, works fine for about 15 mins then it starts giving me errors or disk only reads late like a v7

[wmb88]

Those diode fix boards may never be used as Summone's fix works great. Don't through the boards away coz you can remove all the diodes and solder 2 resistors so that it can be turned into a Summone's fix. See attached image
