Calibrating the replacement V12 PVR802 lasers??

[ShadowKnyght]

To cut a long story short I have a PAL (AU) V12 slim line SPU3170 G wide laser (https://www.ps2repairs.co.uk/catalog/images/pstwo_laser.jpg) in a customers station that has had its' tracking coil go open circuit not short circuit.

I would suggest that this is a Sony manufacturing fault... (or extended play by the customer of GTA:SA on poor quality media)

To fix the problem I first bought the PVR802 narrow lens (http://www.divineo.cn/divineo/images/products/ps2-pvr802.jpg) only, from Divineo china discovering on delivery that it is around 4mm shorter... i.e. not wide enough to fit between the guide rails of the existing laser...

Not very happy as they were supposed to be universal... I still continued and bought a full optical block this time to get around this problem - again from Divineo china... (this one comes complete with its' own rails and motors)

I installed it last night (yes I removed the shorting links) coils are fine still - 5.1 and 5.7 ohms. The disk spins now (which it did not before) but no game loading... no data recognition on either CD or DVD media...

Browser still appears and works as per normal but as if no disk has been loaded.

Checked the old laser pots:
SPU3170 G CD = 268 ohms
SPU3170 G DVD = 1k ohms

New lasers (Lens and full block lens)
PVR802 CD = 432 ohms
PVR802 DVD = 903 ohms

ob802 CD = 304 ohms
ob802 DVD = 915 ohms

My question is - should I play with the pots?

Should I remove the Summ0ne fix 4.7K on the focus coil?
I have done them in the early days just using the 560 ohms on the tracking coil and they are still working fine...

Do I need to remove the entire summ0ne fix to get these new lasers to work? (or is that to dangerous?)

It is just that from what I have read people who have issues with the summ0ne fix don't even get the CD to spin. My issue seems to be more that it just can't read the disks...

Or is it just another bad buy and is the PVR802 laser totally not compatible with the SPU3170 G laser based stations?

Please anyone who has installed one of these replacement lasers - did they work first go?

Did you have to adjust anything?

Help? (Thread stuck for now - as answers may be useful to other members)

[ZootAllures]

I would not play with the pots you should be able to read CDR/CD media at least with NO adjustment at all if the lens was the original problem. Most likley the Mech cd/dvd controller has had it and no matter what you do you will most likley not be able to repair.

[plazma]

Have anyone succesfully replaced a SPU3170 with a PVR802? I got four units with SPU3170 and they don't read dvd anymore.

try using the Lens changer program.
You have to rename The File for the laser type you want to use to backup.nvm
1. Extract zip file into your lenschanger folder
2. start lenchanger program
3a. backup your nvm by pressing r1. rename it so you know whos's pstwo it was, and so that you can rename one of the nvm files in the rar to backup.nvm
3b. rename the proper nvm in your case, the pvr 802 to backup.nvm
4. press l1 it will open up the backup.
5. press start and it will reprogram to the laser type you chose.

I did this and it works.

Thanks go to DAMPRO for releasing this nice application.

Yes but if its not reading at CD based media at all this might be difficult. Unless the chip installed has dev1 and you install the laserchanger.elf to a memcard via another machine, I guess this would work.

[davbere]

Mine read the Naplink cd just fine even though it was a dirrerent laser type.
It was dvd that would not work.

[spedmetal]

Yeah I have had the same experience, but shadow is saying it wont :chinscrat so I guess try and adjust the laser or do what I suggested to boot the laserchanger.elf

[davbere]

well I have had a couple experiences where the laser would spin but not read.
It was usually Bad smd connection where the someone fix was applied or the ribbon was not seated properly.
I have tried 5 of divineos PVR lasers and they all worked, without tweaking the pots.

[ShadowKnyght]

Anyone else done this?

Yeah so far this probably wont work for me as mentioned neither CD nor DVD boot...

Chip has Dev mode - it is a DMS3+

What is the likelyhood that the Mech cd/dvd controller has had it and no matter what you do you will most likley not be able to repair.

Also I have no memory cards for the PS2 as I don't own one (don't have time to play anymore :( ) So can the CD changer software run entirely from the CD or do you need a memory card to get it to work?

How often has an upgrade failed and required you to reload the back up of the EEPROM?

Not sure how that would even help having a back up as if you program incorrectly wouldn't the laser fail and thus no longer be able to boot the software from the CD to restore the back-up?

And the file you have attached - that has the replacement firmware so that the machine should work ok with the PVR802?

(BTW thanks for the replies guys! once again proving that PS2-scene is the best place for technical help - even for the more indepth questions!!)

[N£TM£ÇH]

BTW your getting ripped off by divineo.. you can get those lasers much much cheaper from "other" sellers.

[davbere]

The lens changer program runs from the computer and ps2. No memory card needed.
I use Naplink. There is the ps2 end burned to a cd and the client end for the computor.
Yes if you rename the pvr file in the zip to backup.nvm it reprograms the pstwo to use the pvr type lens.
I pay $26 for the pvr lasers from divineo.

[ShadowKnyght]

yeah they have dropped the price of the complete block (after I bought one of course...) to $30 for one offs (was $49), the lens is $27 for one off's was $30.

If you can get them cheaper than that in single to low quantities then wow - :D where from?? ;)

(Can you get the wide lens's?)

Not plugging Divineo here but Div China seemed rather cheap! Div US, UK and Can were almost twice the price.

I use pukklink/inlink over local network, works very well. No you dont need a memory card for this app. but if you cant boot a CD at all then there is no way to send the elf to the PS2 and in order to make your back-up of the EEPROM you need to be networked to the PC with either pukklink/inlink or naplink. In most cases even if you mess something up if you have a good laser it will read CD's well enough to re-flash the EEPROM but in your case you cant even get that far which really sucks. Shadow.... do this, install pukklink to your memory card (go buy one man they aint much and have more uses then just game saves) and boot pukklink in dev mode with your DMS3+ then send the laserchanger.elf to the PSTwo via inlink over a crossover cable or a localnetwork hub...whatever... then you can make your back-up of the EEPROM as well as reflash it.

Let us know how it goes.

[davbere]

Well said Spedmetal

[N£TM£ÇH]

ill check my suppliers.. but i knoew itslike $20 each if u buy a lot

[cakcetin]

Netmech your suppliers can give for 150 piece 20$?
I change 12 piece wide laser to pvr 802.
When you insert ps2 disc inclined and if you fallow how read disc after 10-20 second wide or pvr 802 laser die:( (after this can read cd but cannot boot dvd)
When you put scratched dvd or crappy dvd disc after a few second if you reset pstwo a few time wide laser die:(
Finally I don't know pstwo lens is faulty or not; but I know crappy media kill all pstwo lens and damn I don't know how say to all customer please don't use this crappy,scratched media clearly I don't know how I can stop this stupid problem.

[ShadowKnyght]

Can you (if not illegal to do so) post a link to where I can download a copy of a working version of pukklink/inlink and naplink - people mentioned that only a certain version will work...

A step by step process for newbie's will need to be knocked together for this as well:

1) Programs and where to get them
2) How to set them up
3) What Hardware is needed - MC? Blanck CD? cross over ethernet cable?
4) Step by step guide to loading the software etc from CD / Memory card or what ever.
5) Any variations required to the procedure depending on - if the console has been chipped or not, if the console has a game booting only chip or a Dev mode capable chip...?

[xrenx]

i have a v12 that wont read discs any more, its doing the same thing yours is the laser is working trying to read, disc is spinning, but wont read any disc, game, movie. no discs work anymore, just stopped working (no chip installed)
its almost new machine. you allso mentioned dev1? whats that in noob talk.
ill be interested in your problem solving.
i would assume that if the laser was shot it would not be red when trying to read discs????

[anarchy2007]

Have anyone succesfully replaced a SPU3170 with a PVR802? I got four units with SPU3170 and they don't read dvd anymore.

I have done 4 sofar (complete unit) it is a simple matter of plug and play. No need to calibrate, the only thing you'll have to do is to cut a piece away of the black plastic cover that is located at the back of the rail so that it can fit on the new rail. Then use superglue to glue it to the metal rail.

Asfar as disks not spotting correctly check the Focus and track resistors. Just had one with the same problem, it had 2 burnt resistors and an open circuit on the focus coil (37K ohm). I replaced the lens with a complete unit PVR optical unit and replaced the 2 burnt resistors.(most propably burnt by the idot that installed the chip, but none the less).

if u replace SPU3170 lens with pvr-802w then the len got trable focusing.
u have to flash the pstwo to solve this problems. don't touch the POT it will only kill the len.

i've don't two so far and thay working great after flashing.

[wmb88]

what's the best way to flash an unmodded v12? I'm wondering if swap magic would boot burnt naplink/ps2link ?

Why would you need to use swap magic? All the chips I can think of that need to be flashed to play back-ups will boot homebrew apps. Unless you are saying you lost your flash all together in which case I do believe all the current chips can reset the flash to a "stock" flash ..... unless you have the modbo and flashed with the latest MI flash .... then I have no idea. But anyway this is very of topic.

You don't understand what I mean by 'flash an unmodded v12'.This means to flash the eeprom not the modchip so that the wider lens can be replaced by a narrow one. If you have an unmodded v12, how do you boot naplink/ps2link ?

opps my bad

[davbere]

swapmagic ?

[oz_shadow]

With quite a bit of success.

On some ps2's i have been ablle to swap PVR-802 with KHM430 and it worked for 20 mins and stopped dead laser.
from my testing on the 3 diff models with differing motherboards CD's will read no matter which laser is installed so as long as u have it chipped or a swapmagic CD u can boot pukklink and do the deed.

Installed another and this time put the eeprom on from the lenschanger and it worked a treat and its still working in the customers ps2 a month or so down the track.

The file available with the slimline eeproms has the PVR and KHM eeproms in it here is the J7 (only marking i could find) WIDE BODIED Laser EEprom i read out of a system last week.


Hope this helps.

is your J7 model can be the one I surrounded in this picture :

[oz_shadow]

Yes sure is the one with the very wide body that has the different cover.

That is strange I have not had any problems like this, I have tested with DVDr (verbatim and Ridata) I also tested with GT4 DL DVDr Ridata disk for over 7 hours with no problems. DVD movies also work fine. All 4 these consoles where PAL SCPH70004 (2 no mod chip, 1 with DMS4 and 1 with crystal chip). I also fitted Matrix diode fix and Pic fix after lens replacement.

The first lens was replaced almost 2 months ago and still no problems??

[levin]

Does anyone have a len change software
well i got a V5 fink its a Rtype laser i got off a mate a HD7 laser
i chucked it on but dont fink its working it spin den stop spin den stop for good
jus wondering can you just run the software of the dvd rom or do i need to connect it to my computer
dont have a lan adapter fing

[darklegion]

HD7 is pretty much just a newer (and crappier) version of the rtype laser,so you don't need to change the eeprom to switch between the two.It could be a dirty lens,incorrectly seated cables,incorrect alignment of the lens height or angle or possible damage to the ba5608 or components around it(unlikely but i've seen it before).Have a good search around the PS2 general discussion and ps2 modchips boards for the solutions..

[m4tty1]

Hi Peeps after some help if you can.

Have got a few knackered sliml lines and some PVR802 full optical blocks I want to install.

I have connected to the PS2 using Pukklink / Inlink using a cross over cable. Connected fine - no problems.

I then execute the lenschanger ELF from Inlink - Hey presto so far so good.

I press R1 to create a backup - this creates the backup.nvm file on my PC - great.

This is where I come unstuck. I copied the PVR802.nvm file to where Lenschanger had dumped the backup.nvm. I renamed the backup.nvm and moved it out of the folder. I then renamed the PVR802.nvm to backup.nvm

Then I pressed L1 which I believe is meant to restore the backup.nvm - this would not work. It gave an error in red writing. I tried this several times with no luck.

What am I doing wrong - any advice thankfuly received?

Thanks for reading.

[spedmetal]

In your windows explorer right click on PVR802.nvm then click properties then un-check read only, then click apply. This should solve your problem.

[m4tty1]

Hi Spedmental

Thanks for the quick reply - thanks also to the creators of this excellent program.

[bunghoolio]

Hi. Can anyone give some detailed instructions on linking the PS2 and PC. Then which lenschange program do you use. How to use lenschange program? I have read this entire thread and can only link my PS2 using PS2link(PS2) and PS2EXEC(CLIENT). I dont understand how to flash the eeprom with the .nvm files provided.Thanks.

[ZootAllures]

Ok heres one for you guys Got a v12 back from a customer Still plays cd/cdr and dvd/dvdr just spins never booting original lens pvr-802w. Replaced hole optical block with same model pvr-802W and no spin on spindle. Then I put the original optical block in that plays CD/CDR and this time just replaced the lens and not the hole block thinking the spindle motor was bad on the new optical block and the disk will still not spin. Tried all 4 types of epprom backups available on this site with no apperant change the disk will still not spin. So I go back to the original lens and with that in the disk will spin. WTF anyone have a clue to help me out?

[spedmetal]

Strange. Maybe the laser you replaced it with is defective?

[ZootAllures]

Actually I tried 2 new optical blocks I got from terry at foundmy got them for free so maybe I don't know they were shit? Damm strange though they would act the same.

Edit just was looking at these very closely seems there is a solder bridge like the older types had for shipping purposes will try to remove it and see what happens

[ZootAllures]

Looks like I solved my own problem that was it removed the solder bridge now it works!

AAHHH!! Yes I have done that too.

[cakcetin]

Today I received 2 piece unmodded pstwo have dvd diode issue,two unit have pvr lens and yes only used original ps2 dvd disc and customer used this 2 system only 5 month.I think dvd diode issue is very big problem for us in future.

[@DaNnE@]

I have a problem with my pstwo lens...some time ago I changed my pvr laser to a wide laser...it has played fine until a few weeks ago...it has trouble reading discs, it doesn't even spin dvd+r dl discs but it plays everything else but it's hard to boot them and some crashes. Is my laser goin to the graveyard or will it help using this lenschanger thing?

[dungbeetle46]

for a start the wide laser is worse than the pvr, not sure why you changed and has your pstwo had any sort of laser protection added to it. if not you could be looking at another laser change

[@DaNnE@]

I have the Summ0ne fix and I think it's working cause I've had a lot of crashes where I can't restart the ps2...I just bought a laser from a modchipstore, they didn't say what kind it was but it was the whole block and a wide one so I hade to dremel som space for it...

[aznheat]

Looks like I solved my own problem that was it removed the solder bridge now it works!

Does anyone has a pic of this solder bridge and how to remove it?

If I've replaced a burned pvr802w by a complete pvr802w optical block, I shouldn't have to flash the eeprom, right?

[ShadowKnyght]

http://www.cyber-mag.com/station/laserimages/static.jpg it will look similar to this but on the side of the lens body...

[tickford]

I have a problem I'm hoping someone can clear up.
I have a SPU3170 slimline that reads cd-r but not dvd-r anymore.So I got a new PVR802 complete laser to replace it with.
Burnt "lenschanger10b6iso.rar" to a cd-r & used the existing SPU3170 laser to boot the disk.Boots fine,select the "PVR802/KHM430" in the menu,press start & then it says "successfully reprogrammed eeprom".All good so far.
Then i put in the PVR802(which has been tested in a pvr802 slimline,so i know it works 100%) in slimline that i reprogrammmed the eeprom for a pvr802,& it won't read cd at all,dvd original & -r sometimes load.Looking at the disk(with lid open) the disk spins,stops,then spins up again,& even loads after that.That does not look right though.

I even tried reprogramming again,but same result.Even tried reprogramming to spu just in case....same result.Its like it hasn't reprogrammeed the eeprom.

Any help appreciated,as its got me stumped. :-pray:

[anarchy2007]

I have found with most later model slimline consoles reprogramming from CD doesn't work, but when I use Pukklink and inlik to run Lenschanger v0.1b6 it reprograms the eprom fine.

[tickford]

Thanks for a prompt response anarchy2007,
If you have seen that happen,then I guess I better reprogram it via pukklink/Inlink,although its only a V12 I am trying to reprogram.

[solvalou7]

Sorry for my stupidity but it's the first time I'm trying to open and mess with my PS2. I have the slim v12 pstwo and my laser is dead (it's the KHM-430). Just got a PVR-802W here and IM totally confused. Can I just remove the KHM-430 and install this one ? or I need to use that lenschanger program ?

One other thing is I read somewhere about some solding points on PVR-802W that should be removed before installing it. Anyone got a picture of where it is ? because I can't find it anywhere.

Thanks a lot !!

[flimflap]

You dont need the lenschanger for changing from khm to pvr! If u have the full optical block u can just replace it. I dont know if you can change a normal pvr into the khm frame.
attached is the "diagram" Have fun!
