Any pics of the foundmy fix? It looks like it will be the one to go for.
Also, does anyone know a failure rate for the PStwos? I mean, how many of these units actually dies out of how many are bought? ANd how many dies that have been chipped (no fix)??
In this unit would the Crystal Chip have any real advantages over the Matrix Infinity?

Me and albert35 finished the fix yesterday!!!
Today he's gonna install it on couple of Pstwos and only time will tell it's effitioncy.

what was r main goal achived with success, but we decided yesterday to add another protection cirquit to the fix. until now we have 3 protections active.

1. The same as matrix, shut down when MECH is LOCKED - 3 seconds from boot
2. protect the RS and the LENS when tray is opend and MECH IS LOCKED after 1.5 seconds of NO RESPONCE from MECH
3. 4 capacitors to save the coils life!!!

after testing we'll decide when to deliver it to customers.

good day

Hey we finally finished our v12 fix.

We have ran our fix in a machine for 3 weeks, with dvd-rw and not one bus hanging or laser burning. and other testers ran with dvd+RW media and have had no problems. Multiple resets and no problems.

We are offering it up, we won't post pricing here, just that its in the vendor area those needing it.

If others come up with a solution we do encourage that R&D. The more people try stuff out the more knowledge is learnt!

what exactly is or does your fix do?
Can you give at least a description of the functioning of the fix?

Problem found in Matrix PIC fix..

During my test of the fix that I'm working on together with XcalibEr I found an important bug... Afther checking I found the verry same problem in the MAtrix PIC fix. Matrix team did not see this problem before releasing this FIX.

The matrix PIC is monitoring the signal on pin K.
It works this way...
If 3 seconds afther startup the signal on pin K is NOT ok PStwo will shut down.
If signal K is disapairing during game play It takes the Matrix PIC 6 seconds to shut down the PStwo... Coils will be burned by that time...
THIS WILL BE THE LONGEST 6 SECONDS OF THE COILS LIFE !!!

Did anyone of you tested this and found the same problem ????

Update... Have to take back words abouth matrix code..
When pin 4 is switched from point K to GND it is fast.. On floating pin 4 It takes 6.sec.

@Albert35 :

The pic code does not work that way, it does the following :

1. After powerup wait one second.
2. Wait at most two seconds for the K signal to go hi. If it doesn't the ps2 will be turned off.
3. If the K signal is high within 3 seconds after powerup the pic will enter a loop checking the K line and it will turn off the ps2 in 200ms if it detects a failure.

I can't see from the disassembly the 6 seconds delay that you mention. Where exactly do you see that?

Allmost...

it does this.

1. wait for 1 second
2. for two seconds test INT in 250ms delay from test to test (8 times)
3. if faild it overflow to the main routine (the "INT WATCHDOG ROUTINE") , and then failed after anoter ~200 ms ceck (fixed that on my code)
4. if the code don't faild on boot up, it jump to the main routine, and there is test ~MAX of 200 tests with 1 ms dealy each, and if faild all those test SHUTDOWN console.

On my debug system it works perfect, on Albert35 test he have 6 second delay (that real strage).

I'll check it on my PS2 tommorow.

Albert35

12-07-2004, 10:24 AM

I'm sure abouth my findings You don't need expensife tools to see this happen.
I hope more people will test this and post report here.

This is how you test it.
1. put the Matrix coded PIC in youre PStwo
2. start a game You can do this with open case with board opside down in top of cover..
3. wait until game is booted.
4. Cut the wire at pin 4 of the PIC
5. start slowly counting from 21 up.. so 21, 22, 23, 24, 25, 26 (for those who don't know how)
6. At the count of 26 youre PStwo will shut down...

This is ~ 6 seconds..
You can tel mutch but it is imposible for a human to count loud from 21 to 26 in less than 200ms

Ok Guys start counting and submit youre results...

Update... Have to take back words abouth matrix code..
When pin 4 is switched from point K to GND it is fast.. On floating pin 4 It takes 6.sec.

TeknoZ

12-07-2004, 10:50 AM

I don't really understand the methodology of this test.
By cutting the wire at pin 4 you are not simulating a mechacon failure, you are just cutting a wire :)

The input pin left floating will probably keep the old value until the internal leakage current brings it low and triggers the ps2 shutdown.

If you want to simulate the mechacon failure you have to use a switch which disconnects pin 4 and connects it ground. Leaving the pin floating does not prove really anything about a pic software bug (which from what I can tell from the disassembly is not present).

Albert35

12-07-2004, 11:03 AM

Will retest with Matrix code and wire pin 4 to ground during play

Update... Have to take back words abouth matrix code..
When pin 4 is switched from point K to GND it is fast.. On floating pin 4 It takes 6.sec.

TeknoZ

12-07-2004, 12:40 PM

To TeknoZ:

You may connect youre pin 4 to ground with a switch.. Did you realy think I was so stupid not to test that... Double checkt it and it will take 6 sec. to shut down PStwo.

Albert35,
I never said or implied that you were stupid.
I just said that the test as you described it does not prove any bug in the pic code.
If you disconnect a signal going to the pic the behaviour will be unexpected since the input pin left floating can slowly rise to a high/low logic state or simply start to oscillate.

If you still have a 6 seconds delay if you connect pin 4 to GND then the situation could be different, but I see nothing like that in the pic code so I still think it has something to do with your test setup.

I am going to test the pic with a switch right now and tell you the result.

Albert35

12-07-2004, 01:19 PM

TeknoZ: You where right.. I tought I wasn't stupid but at the end it's so that I did not realize switching with a 4066 wasn't the correct way... It not hard wired PIN 4 to ground..

TeknoZ

12-07-2004, 01:35 PM

Yea. me and Albert35 thought about it and added a MUTE to the RS2004FS chip at 1.5 sec from boot where INT is failed. so the rest 1.5 sec of INT test will be done without current flowing to the coils.

I believe that there will always be more than 1 solution and, as with the modchip wars, there will always be people who think one solution is better than another. I'm not having a dig at anyone at all, I just wanted to say my two bits worth.

I would really like to see some pics of the foundmy fix so I can compare it with the Matrix fix(es). Do we have any reliable reports from the community of the Matrix fix working for extended periods of time?

One other question, do these laser fixes only need to be considered if the media to be used is crappy quality?? What kind of media can make a V12 laser explode? Verbatim?... TDK?... Shintaro?... I've used all these brands with several V9 consoles without ever needing to administer the Romeo mod. As a matter of fact, I've had nothing but trouble with the Romeo mod, and I have no idea why...

Anyway, I hope someone can shed some light on my queries.

im waiting to see what this foundmy fix looks like too. im not touching my pstwo (which im gettin for chrissy) until theres a fix that looks better than the ones going round now. i read on the matrix fix site that you shouldn't connect the F wire so ill keep a note of that. no need to make the laser work harder to read cd-rw and dvd-rw.

thanks for that site too.. im looking at a crystal which they dont seem to have but they do have the infinity.. is it the v12 version? and should the infinity be more expensive than the crystal?

hi alll
i am going to mod a slimline ps2
i know there are 2 way for the laser fix
the one that uses doides ( which need to be soldered to the Teacking drivers and the focus drivers and to ground)
and the other way is to get the 12c508 and progham it with the matrix code

1. now my question is that if i do it with the doides do i have to do the 12c508 mod as well or will the doides protect the laser totally
are these the correct doides
DOIDES (http://www.dse.com.au/cgi-bin/dse.storefront/41b6f16d078bc1ec2741c0a87f9c078b/Product/View/Z3006)

2. In australia i cant seem to find where to buy 12c508 is it ok if i buy 12c509 and use it instead

the matrix team highly recommends you use the diodes as well to pro-long the life of the laser. and harris.. you can get them in aus. dick smith doesn't have them on the website, but i picked up a 12c508a from one of the power-houses. try www.jaycar.com.au they're usually pretty good with this stuff too.

Can anyone who has had a burnt laser death tell me whether the motor still spins a disc when its inserted and the cover is closed? Reason I ask is that mine isn't doing that, and I'm now wondering whether my PS14 fuse has gone as well as the laser (which is blue - should it be clear?)

I had been assuming that it wasn't spinning the disc because it can't "detect" it because the laser is fried?

Just to clarify, the unit switches on - has audio/video output but just stays on the swirly "Browse" menu as if no disc is inserted.

Fonut

12-08-2004, 11:09 AM

Does the Diode FIX actually reduce the lasers ability to read? Because I have a PSTwo 70004b with Crystal; Diode and PIC-Fix; and BGM is stopping in some games (AC5) or having delays (MGS3).
Also videos (fmv's mostly) are playing "choppy" (like GTA:SA or Killzone movies).
Burnt on Verbatim Printable with 2x.
Anyone got suggestions?

I don't think foundmy will release the detail of its fix. It's only $1.20 at his website, so it must be a simple circuit. No matter what, we'll know the outcome of the fix in the comming weeks. Let's just wait and see.

If any Aussies want a pre-programmed Matrix PIC, feel free to PM me and we'll work something out. I'll have to charge about a $6 fee, due to the chip expense and postage, but it saves you from having to buy a programmer.

I think that's pretty horrible if he doesn't release the details. We don't even know what these things do and they want us to buy them blind. Every other group that has a put out a fix has at least included an explanation of what it does.

12-09-2004, 07:24 AM

What I find strange is that on their page they mention this : "The laser hasn't died and the bus has not hung at all!".

Now, I can't get the pstwo that I have here to hang even without any kind of fix, but this doesn't mean that it doesn't happen to some people due to some installation issues or just bad luck.

The real test would be to see what happens when the mechacon crashes because before that the fix doesn't really have to do anything at all.

12-09-2004, 07:47 AM

The real test would be to see what happens when the mechacon crashes because before that the fix doesn't really have to do anything at all.

Then, the actuall fix would be to make sure that the mechacon never crashes. However, I'm not sure that's easy, or even possible?

XcalibEr

12-09-2004, 07:58 AM

thay won't release detalis cose it build of components everybody can buy, a resistors and a device of 3 pins (could be anything)

I can't understand how a fix on the output of the RS2400FS and two resistors on the input of that chip could prevent MECHCON from getting locked???

The reson for those ps2 to be dead , is that the MECHCON is AT DEADLOCK. so finding the real reason cousing the deadlock on the first place will yell us the solution to prevent it.

johnny

12-09-2004, 01:00 PM

Re we all sure it is the Mechcon causing this? I thought this was still just a theory..

_zaphod_

12-09-2004, 02:53 PM

No, it's pretty well confirmed that the mechacon has been crashing, and that this is the cause. WHenever such a crash happens, you can't eject. The cost cutting redesigns have made the mechacon a lot more senstive to voltage issues, such as might occur when a patch to the mechacon's BIOS is applied during run time.

Note that the mechacon CAN crash on unmodified systems, but if it happens, then it's going to happen most likely when the console is under warranty. And it happens a LOT less.

Incidentally, a replacement lid has already been develoeped (pretty much you cut a hole in the top, and put an extra hinge in) for the PSTwo, and is being sold for way too much money. The sad thing is that seems to be the best way to go for now, until people have solved the mechacon issues.

One theory. It cold be that a small random delay component has been added to the protection check, and that's why patching sometimes cases the mechacon to crash. If the protection chekc starts earlier than expected, you will have the code being patched in the middle of runtime, which will most certainly corrupt the data. And if the check is late, then it may get unpatched durinig runtime, with a similar result.

12-09-2004, 03:55 PM

anyone else using the summ0ne fix? Also, if the foundmy fix doesnt stop the mechacon crashing, is it only protecting the coils from burning? Does the psTWO still lock up?

summ0ne

12-09-2004, 04:00 PM

my fix should withstand even a lockup.

It does not stop a lockup, but should survive it - even if the mechacon is locked up for 5hours straight.
(since it decreases the power on the coils even a bit below normal operating power.)

So if a pswto survives 5h of gameplay, it should survive 5h of mechacon lockup with my fix ;-)

well they only way we got the mechacon to lock was using the MI fix with DVD-RW media. We do not toush the RS200 thing at all. What we do is prevent any voltage higher then 6 volts to the laser, 3 weeks with just RW media, movies and games on RW and no problems, 1000's of resets, even got a movie to get stuck on a sinle frame for 15 hours and the PS2 is still reading RW media. The components FOUNDMY use is not readily available off the shelf at your local electronic store and the components are surface mount install. I think with our tests we have proved no problems with the PS2's we used with Crystal-chips.

12-10-2004, 02:50 AM

What we do is prevent any voltage higher then 6 volts to the laser,

I believe that 6 volts is much too high to save the coils in case of the mechacon lock. Current in each coil is going to be over 1 Amp and the laser will fry for sure.

XcalibEr

12-10-2004, 03:26 AM

I have the foundmy diagrams, but it's write in it "DO NOT DISTRIBUTE", so thay want to keep it in secret!

It's very simple, there are resistors limitors as some0ne did, and on the coils there are 3 pins components coult be voltage or current limiters???!!!

TeknoZ

12-10-2004, 04:16 AM

They probably are just "surge protectors" (I think that's the right name in english).
They are basically some power diodes which conduct above a predefined voltage and discharge to ground (two of the pins are connected in parallel to the coils and the third one is connected to ground, right?).

They are used mainly to protect the inputs on electronic boards from the static discharge (the sparks that you get from your fingers when you touch something metallic after walking on a carpet, for example :) ).

I don't see this as a working protection in this case though, since as I said, a 6v voltage will still burn the coils if the mechacon locks.

It appears to be too simple to be true.

summ0ne

12-10-2004, 05:15 AM

This fix is the most advanced fix out there.

If you read my previous posts you will see DIRECT proof.

It does the same as other fixes, only with less elements, more ACCURATELY and no bad SIDEEFFECTS.

This fix is FULL!!

does EVERYTHING as vandrunen AND MORE.
does EVERYTHING as diode fix AND MORE.
does NOT REQUIRE pic fix.

I have written pages on how the diode fix can be improved and reduced to 1 resistor due to the property of the RS2004FC circuit.

it might seem less to a person that does not understand electronics, but hey - thats engineering ;-)

Also, i've opened up my PS2, but i'm having a hell of alot of trouble unscrewing the small screw located under the spindle which holds the metallic shielding on. I've tried unscrewing it with various small screwdrivers but in the process it's started to strip the screw, so i thought i'd stop before i wear it down so much that i cant unscrew it at all.
Do you have any suggestions for how i can get this damn srew undone? It's like Sony screwed the thing in with a bloody pneumatic driver or something!

Losen the 4 screws holding the laser... move the laser a bit, and you got all the space you want... btw. it's the same screws at the buttom...

It is the same screw as the ones in the bottom, so it shouldn't give you any trouble... but if you f***** the screw up, then you have a problem...
Then you have to 'remove' the screws head, to get the GND plates apart.

i havn't yet worn the screw down, but i've just bent the tips of 2 mini electrical screwdrivers in the process of trying to get this thing unscrewed.

I swear to god that this screw is posessed. If it can bend 2 screwdriver heads and still not budge, then there is a greater being that is holding this thing is place......
Are they the same as those encountered on V4 and onward for the inner shielding? some of them were screwed tight, I would do like this: I have a small electronic screwdriver with a phillips head (a flathead would also work if it is not too large or too small). I put the driver on the screw, with the palm of my left hand I push DOWN, while I turn the driver, usually with pliers (cause there's not enough grip to turn by hand if the screw is screwed tight). this way the driver stays in the "groove". For some I had to push down really hard.

Yeah, this thing is definately not budging. I'm just going to get a nice small drill piece and slowly drill the head off. Then unscrew the rest with a pair of pliers.

Also summ0ne, i've decided my PSTwo will be tested using nothing but your fix to begin with. I figure it's best to test the nice simple fixes first.
Should i be using a 1W or a 1/4W Resistor for your fix? By the looks of it you are using a 1/4W, but it's a little hard to tell scale on the images.

Just got the Foundmy fix's today. Just so everyone knows the parts are so f***ing small... good luck. You MUST be a highly skilled installer to do these. I have been working with MoBos and soldering for years and this is not the simplest by no means. About as hard as it gets really.

No normal user can install these. I am NOT putting down Foundmy at all. Terry warned me before purchasing and I am fine with it. But they really need to be machined in a waffer board and made into a product.

You need some small ass tweezers just to grab hold of one of the chips.

Just a fair warning... Terry get these to manufacturing fast....

Ripper team seems to ahve some more info intheir deadbeef file (chuckle) they now say that they've SOLVED the mechacon crash on patchingproblem, by using a special parallel wire "low votage patch technique" or something, an dthat ONE other chip uses it too, though they won't say which ones. They also claim that any 5v modchip will crash the mechacon of a v12.

It decreases max power on the tracking coil.
Because the tracking coil is the one in danger.

Advantage over diode-fix:
more accurate, cause it is a resistor with a specific value, instead of diodes in series which can only go in steps: 0.6v - 1.2v - 1.8v

Advantage over vandrunen:
it does not affect reading ability because it leaves the focus coil alone. and it does not decrease the supply voltage to the rs2004chip, that can cause errors in the chip operation. it is also a low-power fix, does not need huge elements and a very skilled install.

advantage over all fixes:
it actually works and is easy

P.s:
Most teams are taking advantage over customers and installers.

The ripper team says that 5v chips cause crashes cause they want to sell their more expensive 3v chip.
THEY ARE LOOSERS AND INSULT THE INTELLIGENCE AND TRUST OF EVERYONE THAT READS THEIR DOCUMENT!

Maybe I'm wrong but focus means the "space between laser and DVD" and tracking means following the trace where pits and lands are on it? But by decreasing the movement of tracking coil its possible to loose the trace and DVD gets also unreadable? Maybe your fix works like diode-fix and holds the voltage in safe range, but I can't imagine how it should prevent the machacon to crash. In case of crashing the mechacon there will be also "full power" at the coils, or not? But I agree your fix is much smarter then the matrix-diode one.

vanDrunen wrote the folowing..

The 560 ohm resistor will only make a fairly large current (compared to the one going in the RS2004FS) flow between the two control lines that the Mechacon has to supply. Because of the high impendance input of the opamps it will hardly make any difference and only put more strain on the Mechacon's outputs.

2 notes:
- This "fix" will not damage your PSTwo console though.... the Mechacon can take this extra current drain... but it will not help you either
- Do NOT put a 2 KG brick on your PSTwo... I was just kidding... it will put scratches on the lid

The second note I can live with but the first one is not right..
The lines where the Summon fix is connected to are not coming from the MECHANICS CONTROLLER but are coming from the DIGITAL SIGNAL PROCESSOR and are connected to the summon fix thru 2 resistors of 1Kohm..

@foundmy :

Looks like you are just lowering the tracking gain by 25% and limiting the voltage on the coils to 6volts.
Nothing is being done to prevent the mechacon from locking up.
As I stated on my previous message, if this happens the coils will fry anyway since 6 volts is still much too high for them (1.2 Amps in each one will burn them).

summ0ne

12-11-2004, 04:57 AM

I think its time... I will be modding my PStwo tonight with MI using the summ0ne fix. My only other question is... should I use the MI PIC fix too, just to be safe?

On a side note... those foundmy fix components are, as previously stated, way too small to solder by hand. Surely there are larger versions of these things so that us lay people can see them.. :p I'm sure the fix does its job, but seems like it will be harder to install the fix than actually install a modchip.

summ0ne: Is it alright to use a 600R resistor instead of a 560R?

I am not sure.
Since 510R is the strictest case, 560R is cool since it relieves the sled motor and makes sure all games read at full speed. 600R might not prevent the burn of the coils.

Still, i went with 560R since its available everywhere.
It is in the renard scale of E12 and up, so if an electronics store doesnt have that, they are from another planet :-)

summ0ne

12-11-2004, 05:07 AM

SummOne, when vanDrunen was asked about your fix he said it's not useful at all.

http://web02063.prolocation.net/phpBB2/viewtopic.php?t=3371&start=210

He gives an explanation which is far beyond my non-engineer-mind.

I still stand by my every word.

BTW
someone asked about the pic fix - it will be more of a protection stopping even a mechacon crash, so u might use it in conjunction with my fix.

I personally dont use it, i am still waiting for my first burnout, so i can see where my fix has flaws, if any.

And everyone talks only of crashes. I think that a crash is only 1 way of loosing coils. They can also be lost during normal reading, since i lost a v9 laser that way.
I have noticed, that chipped pstwos make faster tracking-lens-movements than non-chipped. Just compare a chipped cd game and a non-chipped. You will hear the difference. With my fix, the sound is lower than both.

I dont know much about mechacon patching, but if you could somehow delay the tracking jumps through delays in patching, you could maybe make a safe modchip.

summ0ne

12-11-2004, 05:57 AM

you must have done something wrong - it is impossible for the fix to not work with some media and work with other... why?
Because this fix does not control optical properties... but controls geometrical properties.
So it should read every 12cm 80min disc the same, as the sectors are the same distance apart on all discs

Yesterday I modded my first PStwo. I installed Ghost2 chip and 560 ohm resistor on tracking coils only, didn`t use any pic or diodes, just 560 ohm resistor for protect tracking coils. After replacing PS2 backup with DVD movie console freezed at browser screen, I pressed reset button few times, pressed and hold it for a while, but all without effect. I must to pull the adapter cable out of console. After I reconnect the PS2 and turn it on it worked ok, like nothing has happend. The "freezing" occured again 30 minutes later, tryed again with reset w/o success, pulled supply out, turn console on, everything boots ok, no laser/coils damage suffered. Both times console lockup lasted for 3-5 seconds untill pulling pwr supply out. I suppose without protection it would be enough time for coils to get melted.

If u look at diagram for Ripper 3.1 installation, u can see +3.3V is soldered on fuse ("50" is written on it) but there are also another mainboards with not fuse in this place but capacitor or resistor (just another component, dunno whats that exactly). And....i have found that only mainboards with fuse in the place kill laser. I have only burnt lasers with these mobos (with fuse). And i installed chips also to the another mobos (with capacitor/resistor) and the pstwos are still working.

and its not myself that has tested it, others have too, their systems been using dvd+RW for 2 weeks almost now, no problems.

So why would I release soemthing that i didn't feel that it would fail. if it failed for me, i wouldn't of never considered remotely coming out with something. I am not one of those guys that willl copy other people's ideas and make up stuff just to make a $1.00 .

summ0ne

12-11-2004, 03:56 PM

yes, thats what i mentioned to u - u gotta make sure that you dont solder it so it puts a big strain on the SMD resistors u solder to.

1/4W are more obedient, with more W u have a bit thicker pins that you have to adjust before soldering so they allign well with the solder points, otherwise they might snap off the contact of the SMD.

1/4W are same as the diodes in the diode fix, 1/2W can be used, altho more care is needed.

first bend one pin to form the U shape.
then clip them off about 5mm from the resistor.
then bend them to one side, so when the resistor sits flat on the mobo, the pins are exactly touching the solder points.
only then dip the pins in flux and solder them to the points, holding the resistor with the tip of your finger against the mobo

im not saying that it doesn't work at all. but if you dont produce any technical papers on your fix, no one can look it over and suggest if it can work or not. the pstwo's that you have tested this on might be a lucky few that just wont lock up. like vandrunan said, "you can put a brick ontop of the pstwo. just because it doesn't lock up doesn't mean that the brick is the fix".

summ0ne

12-11-2004, 05:55 PM

if the max voltage on it is 2v
and its a 560R resistor:

then the max power on it is 2^2/560=1/140W
and since its a 1/4W - I figure it will heat up just below 1 degree C
:-)

Thinkdiff

12-11-2004, 06:06 PM

hehehe. Ok. I got the 560R 1/2W resistor hooked up (used 30AWG wire so the SMD components would not be stressed) and 2x 2 diodes on the Focusing coils.

Just powering it up now :o

summ0ne

12-11-2004, 06:08 PM

the foundmy fix decreases the gain (and output voltage) on tracking by exactly 25%

meaning it decreases max power to 0.75^2=56%

that might maybe burn coils at a mecha crash, but definitely prolongs their life during normal reading.

those smd transistor-like components are connected in parallel to the coil inputs/RS2004 outputs.

we dont need to know what they are in order to examine what they can do:

the only thing they can do where they are soldered is to short the outputs of the rs2004 in order to save the coils.
but they are way to small to take such a load without burning up :(
if the coils can burn, why couldnt these tiny things?

plus shorting the rs2004 will damage it or its fuse.

so the little black things are no good :\

But the resistors are, they do the same job as my fix, only a smaller R value would be more safe, because 56% is still too much.

But definitely a good choice of leaving the focus part alone, i think foundmy even discovered that putting stuff on the focus channel might cause more mechacon crashes - due to more read errors in lack of focus. So he told me on msn.

In the end - the fix is very good in conjunction with the pic-fix, but migt suffer on its own.

Thinkdiff

12-11-2004, 06:16 PM

pstwo working great with ***4, and combo 560R/diode fix.

summ0ne: so you're saying having the diodes on the focus coil could actually make it worse? Should I take them off?

summ0ne

12-11-2004, 06:25 PM

I think that might be so.

Tracking is for reading/speed.

focus is for focusing - no focus => trouble

and the focus coils are at high power as it is in normal operation and they dont burn up.

that is why u cant decrease vin to lower than 6.5v - because u clip the focus voltage trying to save the tracking coils.

the focus coils never burn up anyway

P.S.:
well im busting my ass being wreckless - soldering only 1 resistor to make sure it is enough. how about u help me.

use only the 1 resistor, when the first burnout occurs, we examine it.

it is the only way to find out that it does not need nothing else.

Thinkdiff

12-11-2004, 06:27 PM

well this is a customer's PS2 so I'd rather not try to get it to burn out. This is also why i'm making sure all the fixes are correct. I understand what your saying about the Diodes. I'm gonna leave them on for now and when I get the PICs, I guess I can remove them.

that guy is from croatia, talked on the phone this morning :)

i tried convincing him to leave it crashed for 10min, but i guess u cant watch your pstwo struggling like that without taking action.

If it crashed twice, it will surely crash again, maybe when the customer is away in the kitchen grabbing food or something. if that pstwo does not return, we win :-)

I have sent out personally 20pstwos and trust me - people burn media at 52x and crazy shit like that. no returns yet

Somm fix on new PStwo with ***4 LITE + ***** 1.1 + Sony DVD+R disk running perfect for 3 hours..

Boot times are great and system running very stable. I have seen 5 other crashes and seen the symptoms before crash.

To me this seems very stable so far.

Next is the Foundmy fix on the next system.

I don't think you should use 560R/Diodes with foundmy. instead of foundmy, do PIC fix.

Can I install the 560 ohm resistor in conjunction with the diode fix already installed to the tracking coils?

And I checked out my PIC fix. The K point is fine though it is not parallel to ground as suggested by T.M.T. Maybe that's the problem?

no take the diodes off the tracking coil, and put on the resistor.. you can live the diodes on the focusing coil.

Ok, thanks: )

Personally, I've only had 2 PsTwo's with the laser burning out using just the diode fix. And this is out of 20+. Both of these had "4C" date codes. Not sure if that means anything...

Anyways, I'll be trying this out and will report results.

Well, with the foundmy fix there is no need to protect from lockup Because it does not LOCK UP!! Using the MI fix we got it to lock up instantly, but with Foundmy fix it never locked ONCE.

IF you feel soo insecure using the MI PIC.

But for over 2 weeks I have used nothing but DVD+RW and not a single issue, watched movies played games all on DVD+RW.

Well, with the foundmy fix there is no need to protect from lockup Because it does not LOCK UP!! Using the MI fix we got it to lock up instantly, but with Foundmy fix it never locked ONCE.

That does not mean anything. My pstwo here never locks up (and believe me, I have tried everything) with the pic fix and it never locked up even before the pic, with just the diodes.
Does it mean that the diodes or the pic are preventing the mechacon crash?
No, it just means that my pstwo apparently doesn't have that problem.

The foundmy fix with the resistors is exactly what the matrix team suggested on their news page on Nov 4 and they released the pic code 18 days later.
If the resistors were preventing the mechacon crash why didn't they just use what they suggested in the first place and released the pic fix instead?

The surge protectors on the coils as I already said won't protect them in case of a lockup as the voltage (6volts) is still much to high.

To prove a fix to be working, at least 100 consoles form different users are needed for testing. Only time will tell which fix is effectively working. I suggest the moderator to start a poll and let forum members vote which fix does not burn laser: Matrix PIC fix, SomeOne fix, Foundmy fix....

TeknoZ

12-12-2004, 06:59 AM

read it a bit more carefully..
Thanks for suggesting that, but maybe you should read more carefully my reply. :D

Stating that the fix locked the console doesn't make any sense (unless some error was made in installing it), as it doesn't the fact that lowering the gain of the coils driver will stop the lockup.

I am an EE and I prefer to have an explanation on how things are supposed to work and then I can draw my own conclusion.
The foundmy fix lowers the gain of the coils driver by 25% and limits the voltage applied to them to 6 volts.
This is still much to high to protect them and in a sense is also worse than the diodes fix since by lowering the gain you are also lowering the "good" signal, not just limiting the bad spikes.

ideas_man69

12-12-2004, 03:34 PM

- The foundmy fix really is horrible. The 25% decrease in gain does make a little difference, but those components that were supposed to "take over" some of the coils's currents are inefficient. They can very well take over some of the little peaks, but during a DC current through the coils it will hardly make any difference. Using some full-size TIP132 FET's instead of those little transistors or whatever they are would have a LOT more effect.
Someone can only prove me wrong here with showing me some nice graphs of a DC voltage over the coil vs. the current through the coil (and that last one better be low!) and some specs on the actual component used.

OK.. so the Summ0ne fix is a good idea.. but not the final solution. Currently people should apply the Matrix Fix (please use a 12F675 PIC instead of the 12C508 and program it with my recompiled one) in combination with the Summ0ne fix, but instead of 560 ohms, use a 1.2 K and 1 K resistor in parallel. This would make a 545 ohm resistance and showed better results (at least on my boards)

it is not neccesarry

560 is the best compromise between saving the coils and not wearing down the sled motor. if u use too low resistance, your sled motor could die early!

if u have a dilemma where u dont know which combination outweighs the other due to multiple factors, go with the simplest one!

No that is the beginning of the fix, he hasn't completed and uploaded the entire thing yet.

You can download his re-written Matrix Fix hex files to use with the new 12f675 chip, and he also has a diagram there explaining how the tracking works, but he hasn't yet uploaded all of the instructions on his next fix.

Today is Tuesday, and he said he'd have it online by Tuesday, however he's in a different timezone to myself, and is no doubt behind me. So for all of you (us) Aussies or Kiwi's we'll have to wait until Wednesday until we see it.

Now if only i can track down some 12f675's, as neither Dick Smith or Jaycar are selling the things......

I only just got my replacement PSTwo back from Target yesterday, and they have a 2 week exchange policy at their store, anything over that 2 weeks and it has to go back to Sony for repairs.

go for the matrix pic fix (but use a 12f675 and vandrunen's re-written file) and the 560ohm resistor on the tracking. should be perfect. then when van finishes the v2 fix, you can just program the chip with the newer fix.

wmb88

12-14-2004, 09:45 PM

I think if Modordie's finding is true, we can just simply copy Sony's fix by increasing the 30k to 68k in the tracking channel as this will reduce the gain by 50%, which hopefully means no high dc voltage from the BTL output stage when crash happens. All we know is that the BTL output stage is driven by a level shift that gets the signal from the OP amp. By reducing the gain of the OP amp will effectively reduce the amount of output applied to the tracking coil. So, Modordie please we need a hi res pic from you.

He was just using my picture. I am getting 63k off of these guys.

So, they are 63k resistors! I wonder if I replace the 30k's on the v12.0 board with 2x63k, will the laser still read ok for most of the media? If ok, I can say Sony just played with gain control tricky.
Let's hope Sony's fix solves the problem.

that would be sensational.

Thnx Thinkdiff---

I dont see any other differences. Although some of the numbers are kinda hard to read on that scan of yours. Everything I can read tho, looks the same.

Interesting news guys. I had a lockup. I was playing GTA:SA and tapping reset about every 2 mins. Then I tapped reset and it froze up on me. I tried to tap reset and it wouldnt go. So this is what I was hoping for. A crash!! I left it go for about 5 mins, then pulled the plug out of the back. Power down. I powered up again and opend the lid to look at the laser. FINE! NO SMELL. So I took it apart and checked the resistance on the coils. 6.2 ohm on both!! Checked all fuses and resistors, fine!! I just got done putting it back togeather and Im trying to get it to crash again as I type. It does seem to have a little trouble reading my dvd-r games now. Will keep you posted.

so bst, are you the one with the 12.1 board or one of the other fixes?

Ya, Im testing the "12.1" with a Crystal-Chip installed / NO FIX.

Looks promising, though as BST Console confirmed, this new "V12.1" system did lock up even after "Sony's fix". But isn't the replacement of the 303 resistors with the 663 ones similar to the findings of T.M.T. using additional 303 resistors in line with the current ones? This is also part of the foundmy kits by the way.

I picked up a brand psanking new replacement (exchange) PSTwo just 2 days ago from Target here in Australia.

I wonder if this is also one of the new sony refined versions, or if us Aussies are still stuck with older stock.
I guess the only way to find out is to open the bastard up.......

Can't wait for your results BST Console! I just picked up a v12 PSTwo at CompUSA on the 9th/10th, it was part of a shipment they recieved that day after being sold out for over 2 weeks. I sure hope it's the most up-to-date version. Did you ask the Wal-Mart where you got yours what day they recieved them? I guess I'll have to open her up and check the board. I bought the CompUSA replacement plan so if I screw it up or it screws up I get an in-store exchange no questions asked. Got it all for cost too since I work there.

I bought a ***4 Pro but I plan on not installing it and exchanging it for the Crystal Chip and installing that...

Im having MAJOR trouble reading DVD-R discs. Orig DVD games and CD-R games load fine. DVD-R games are VERY VERY slow to load, Noisy too.

This was one of 4 PStwos that I got from Wal-Mart. They received them that same day (12/14/04)

Hmm that doesn't sound too promising. Looks like Sony's "fix" doesn't seem to work all that well.
I'll open my unit up in a few and see if it's a new version.

It brings a virtual tear to my eye to see so many dedicated fans, sacrificing their consoles for the sake of a common cause. And destroying gaming hardware in the process.....
Oh the humanity!

Im not getting a single DVD-R game to load and stay up. Sigh.......
Im gunna open it up again and recheck all points of concern

Edit-->
Everything still looks fine inside. Im not sure what to think. The laser lense is as clear as can be, coils are reading 5.9 and 6.1. It will still recognize DVD-R but not load it all the way. All other medial works fine (DVD CD-R etc)

I just opened up my new V12 and took a look. It seems like i have two completely different resistors again to the ones that you guys are talking about.

On the left i still have the original 303 indicated ones, but on the right i have two which are indicated as 103.
On all of the other diagrams i've seen, they are indicated as (what seems to be) 01C, are these the same kind of resistor, just named differently?

I've included a pic for anyone interested. Remember this is a PAL V12, located in Australia.
