    This ones a noggin scratcher for me but maybe you can help.

    Recently I modded a V10 ps2 with a duo 3 ultra. I also did the laser fix.

    PS2 ran great for a few days then started not being able to read games. And eventually wouldn't read anything.

    I assumed the laser had somehow burned out.

    I opened up the ps2 with the top cover tray off.

    The laser does everything it's supposed to. It slides over, goes up and down, flashes..etc

    So i'm wondering..why doesn't the disc spin and why doesn't the ps2 know there is a disc in?

    Any advice would be greatly appreciated.

    -Tom

    Well, fuse ps13 is blown and not causing the disc to spin.

    Now two questions:

    1. Where can I get a replacement ps13 fuse.
    2. What made the fuse blow in the first place?

    Any ideas?

    So, I got bored and made a jumper wire for ps13. Put the unit back together...still not spinning. Hmm...maybe my jumper wire was too thin?

    Like I said, the guy I sold it to was playing it for about a week when the problems started happening. I happen to have a spare board here for practice that I will replace the fuse with.

    Thanks for the advice though.

    No problem. Also meybe try cleanign the laser lens. You'd be suprised to see how a little cleaning can fix many DREs.

    Any other questions, hit us up! We're here to help and be helped!!!

    GO GIANTS!!

    Well, I installed the fuse and got continuity after install. Powered the unit on, still get "no data." Disc doesn't spin, laser still flashes once when unit is turned on.

    I really doubt it's the mod chip, but I might be removing that next unless someone has other ideas?

    I am no longer posting expecting for replys. More or less a journal for others that come across this and have the same problem.

    After removing the mod chip and taking off the laser save, the unit still will not spin the disc. I am starting to think it's a laser problem. (meaning new laser)

    The guy said the ps2 stopped reading games over the course of the week, not just at once...like would happen if a fuse was blown.

    Anyway, if someone happens to have a website that they use to get spare parts lake a new laser, let me know! Thanks much guys.

    Hey Stabby, thanks for being the one to being nice enough to reply to my posts. What do you know about the LA chip? I read some where that the LA chip controls the spindle motor.

    No problem, K. That's what I'm here for. Unless I'm busy, I usually check this site once a day.

    The LA chip is what usually goes first on the V9 and V10 version consoles. I have replaced 5 of these chips with success in fixing the laser motor and 3 which it did not repair the console. It's almost hit or miss with that because there isn't an easy way of testing the chip with the power board off when you disassemble the console.

    Here's what I would do for a V9-V10 DRE.

    First, clean the laser lens. Test PS2
    Next, clean ENTIRE laser assembly, bottom lens and mirrors.
    Then, I would replace the LA chip. Installing the Romeo mod after installation.

    If all that doesn't repair the console, I would buy a new PS2. The cost of the laser for old FAT consoles is around $50 not including shipping. It makes more sense to me to invest in a new machine. Ya it's more expensive but saves huge headaches. Which do you value more? A couple extra bucks or your SANITY? hehe

    Like I usually tell most people when I try to help on this site, if you want to try a real time chat, Windows Live Messenger stabby209 is my screen name.

    Stabby, again thanks for replying. I looked for you on messenger, but you weren't on.

    You said fixing the LA chip will enable the 'laser motor' to function again? The laser seems to be fine. It moves like it's supposed to, etc. The only problem is something is telling the system there is no disc in it.

    So the problem would be either.

    1. Laser is at fault by not being able to detect the CD/DVD that is in the drive. - I have tried a few things to the laser to get it to see the disc. None of them worked. Adjusting pots, cleaning, Adjusting laser angle, etc.

    2. Some chip that controls the spindle motor is burnt out. - Checked spindle motor connection to the MOBO and it doesn't look or smell burnt. Which I was told are signs of the motor blowing. Also, spindle moves freely when spun by hand.

    Iders?

    Thanks guys.

    PS - This might be the result of a failed romeo mod... I've done them in V9's before but this was my first V10. I followed the 5v location exactly as diagram showed. Maybe it just didn't work.

    OH! I forgot! Games where loading SUPER fast for being read off the disc, when the unit was actually working. Movie scenes in games often got cut short at the end due to the ps2 wanting to load faster.

    Well...after all of that, I think I found the problem.

    After reading a downloaded "fix your ps2!" guide, I found the problem.

    One of the pins on the ribbon going into the motherboard from the spindle motor was torn. (picture below)

    Now i'm just hoping I didn't mess anything up by assuming it was every other problem under the sun.

    The book said "if the motor doesn't move it all, it has something to do with the spindle or ribbon, nothing else...Once I get the new part, I will post to let you all know how it goes!

    Try reading CD games / music, and see if that works, if it does prob the laser (u can fix it with the pot adjusting and and turning the white wheel, if its in the v10, but this is really time consuming and drives me crazy.), if not then LA chip.

    Yeah, definitely was not that ribbon. Laser moves now and everything...it still thinks there is no disc in there though??

    I am having a similar problem, I watched you're video and the symptoms are almost the same. Except my laser makes this loud clicking noise after I put the game in. The motor doesn't spin the disc, but it worked better before I started messing with the console, it would read the disc, make a clicking noise, and then the disc would spin like 100mph.

    But the motor doesn't even spin now, and I am wondering if the laser is actually what is causing the problem and not the motor or ribbon cables or anything like that. I ordered a new laser, but it's coming from Hong Kong so who knows when it will get here.

    If worst comes to worst, then something on my motherboard is bad other than the fuses (I've checked all of them with a multimeter). It could be the BA or or LA chip, but I am not going to install one of those damn things, that will be once heck of a head ache.

    Really, the worst thing about all of this is I had installed a mod chip onto the motherboard and it worked great for about a month (took about 5 hours to install), but now all of a sudden a few hours later after playing a backup copy of Contra - Shattered Soldier, it's all f'd up.

    If I manually set the laser at a higher position, closer to the white cog the laser will move itself downward on the rails, also the laser lens will move up and down and flash red light. Which indicates that at least a portion of the laser assembly is working, the only thing which is holding me back from easily fixing this problem, is the spindle not rotating the disc. I even managed to temporarily fix the laser by completely disassembling and reassembling the PS2 with no screws, but when I put all of the screws back in to the motherboard heatsink and PSU, it suddenly stopped working again.

    They're could be a short somewheres, in my ribbon cables but I very fragrantly remember checking those and verifying that they were in working condition.

    As you can see we both have somewhat the same problem here, and the worst part about it is we both have the same mod chip installed. The only difference between you're PS2 and my PS2, is mine's a version 7.

    Right now I am at the point where I am posting in all sorts of PS2 forums, seeking for help or some kind of knowledge on the issue. I hope someone posts some really useful information in this thread which could help me solve or at least diagnose this issue. Thanks

    As we speak my unit is still sitting next to me broken.

    Does the disc do a half turn or even a quarter turn?


    Just to recap -

    You power the unit on, the laser moves, bobs up and down and flashes a red dot once? The disc just doesn't spin at all? If it moves even slightly, you know your laser is either shot, or needs an adjustment.

    The spindle doesn't even spin at all for me anymore, at first I could get it to spin, but at around the 4th time I disassembled and reassembled the console it stopped spinning at all for me.

    At first when I encountered this problem 2 days ago, while I was working on the laser. My fingers would wear all the grease off that one slider rod and when I put it back together, the laser wasn't able to move. So I cleaned the rod with isopropyl alcohol and then put some lithium grease on it and the motor was able to spin the disc, even though all I did was put a little bit on the rod and the worm gear.

    The problem that my unit is giving me now is the same problem as it gave me when the laser slider rods wern't properly lubricated. Now that there is a ton of lubricant on there, maybe that is the problem? Today, I was planning on cleaning all the grease off of everything in the laser assembly with isopropyl alcohol and then reapply a new coat of grease.

    If that doesn't make the motor spin even a slight amount then something isn't allowing the motor to engage. But my lack of knowledge on PS2 CD/DVD drives prevents me from finding this problem at it's source. If a laser is bad will it force the spindle not to spin? I can remember turning the unit on a couple days ago with the lid off the CD/DVD drive with no game in there, and watching the motor and seeing it spin about 1 full rotation.

    It's not doing this for me now, and I might try to reinstall my spare cd/dvd drive which I know has a working motor (because I hooked it up to my spare motherboard which has some sort of fault in it due to a failed mod chip installation). I could see the spindle rotate about a full turn in that test when I tried the unit with the lid off, but my earlier repairs to the motherboard didn't solve the motherboard's black screen problem. But it proves that my spare cd/dvd drive has a working motor.

    If the motor still isn't kicking in after reinserting my spare cd/dvd drive onto my motherboard with the mod chip, then the only thing which would appear to be my problem is a bad BA or LA chip. Or another component is bad which aids in the act of controlling the laser or motor, besides the fuses because I know they are all good.

    If the spindle doesn't spin on this reattempted spare cd/dvd drive insertion, then it appears that I have wasted $50 on a new laser. When the real problem is on my motherboard with the blood and sweat from my mod chip installation.

    I might also test the BA or LA chip while im reinstalling my spare cd/dvd drive, to see if it's good, but I don't know the first thing about testing one of those..is it just like a fuse?

    Anyways, that's what's going on with my PS2 at the moment.

    Edit: The working cd/dvd did not work on the motherboard with the mod chip. You know what that means? Yup something is f'd up on the motherboard and it's not a fuse. I checked the BA and LA chip with a multimeter and I was able to get a reading but I'm not sure exactly what to look for but I was able to get continuity like what I get when I check the potentiometers on the laser.

    It looks like I wasted 50 bucks on a laser that I didn't need, what I need now is a new motherboard. But I'll have to re-do that damn mod chip installation, I am so not looking forward to that. I think I'll install the mod chip a little differently this time, and I'll have the mod chip next to the BA or LA chip, so I can get the most minimum length for my power wire, and I'll just solder the ground wire to the side of the motherboard.

    I don't know what went wrong on that motherboard but it was full of problems from the beggining. First the fuse that powered the fan died, then the 3.4v regulator fuse blew on me. I replaced all of those and the console was working like a champ, but then she kicked the bucket and something got majorly f'd bad on the motherboard, it could still possibly be the BA or LA chip.
