Laser or Chip problem?
I have a v9 ps2. I recently got it modded with a CC 1.2 and the romeo mod as well [I have no idea how to check if the romeo mod was actually done :( but he seemed like a good guy]. Anyhow the problem I have is that it won't read backups all the time.
At first it worked fine but then it had trouble reading disks everytime I powered off then turned the system back on. I thought it 'fixed itself' as I left the ps2 in one place for awhile [the floor] but once again it started having problems. It seems to occur everytime I move the ps2 like from the floor into my tv stand. To try to fix this I try to hard power off the system twice [the I/O switch at the back] and it used to work. But lately I've been having to turn it off much more than twice to get it to work. I also tried it with retail games and it seems to read them more reliably but I have to test this a bit more.
Sorry for the long post. I'm just trying to clarify whether it's my laser dying or maybe a wire is loose from the installation. Thanks! :cool:
I have a little experience with V9 units, but I am not an expert. After using and modifying about six of the things I have found that the laser lenses are not very "long lasting". I have had lasers wear out prematurely by playing scratched disks on them, so I would hazard a guess that it is possible that your laser is getting weak by playing burned disks.
Personally I would not dream of playing "backups" on any PS2 because the laser lenses were never designed to read burned disks. If it does read them, that is just "good luck" so to speak. Sony never intended for them to read anything other than factory disks. As I'm sure you know factory disks are much more reflective than burned disks and do not require the laser to "work as hard" to read them.
This scenario is why I installed hard drives in all of my current V9 consoles and run the games off of them. This way I am not using the original disks any more and do not have any reason to "back them up" so to speak. Also this scenario has the advantage of not using your laser lens at all, thus saving whatever life it may have left in it for future endeavors.
Take this information as just my personal opinion. I realize lots of folks play "backups" all the time with good success. I understand the desire to do this if young children are involved. If you can set up a hard drive then the kids will not have to handle disks at all.
I guess I just do not like the idea of pushing any equipment to do what it was never designed to do. To give you an analogy I ride a 1976 Harley Davidson FLH that still runs like a dream. I take care of it and do not treat it like a hot rod (meaning I don't try to get it to do things that Harley never intended it to do). I have friends that have trashed Evos trying to turn them into the next Arlen Ness showpiece and I just keep cruising down the highway.
In closing if you find you do need a new laser lens richspsxparts.com has the new 400Q lasers in stock. I just installed one and it works pretty good. It doesn't read burned disks quite as good as a new 400C does, but from what I have heard they haven't made those things in years. However the disks it does read it does so very quickly and smoothly.
Thanks for the great description Hoyt. Yes I have been looking for a hard drive for awhile now as I understand running games off an HD is much better. I guess I've been testing alot of games lately but I've only been playing them for no more than 10-15mins each. I just hope I can get a HD before my laser dies so that I can still load HD loader :(
I'm still gonna try a few more things to see what's up. Thanks again.
I am about 96% sure the box my v9 PS2 came in (and possibly on the PS2 case?) says that my PS2 can read DVD-R and possibly +R discs. Obviously, this was intended only for movies... but it's an indication that Sony was selling the PS2 units as being able to read burnt media.

If anyone can clarify this, please feel free. I can always drag my old box out tonight to confirm. ;)
Zelu: You can set up the v9 Ps2 to run HDloader or uLaunchELF off of a memory card with the Exploit trick. If you set that up ASAP you wont have to worry about your laser. I also just realised you said you have a CC 1.2 which can also boot apps off of a memory card, HD or USB stick.
Yea I'm definately in the process of looking for an HD right now lol. Gotta salvage the ps2 somehow :p
So after some playing around I thought my ps2 laser was dead b/c even after rebooting 10 times it didn't work. Then I tried turning off the power I/O switch from the back and shaking the ps2 a bit :lol: and that worked after 2 attempts haha. Does anyone know why this might get my laser to work again? After loading a disc however and then turning it off using the front button or even resetting the ps2, it will rarely read the disc again :(
Could there be a loose wire somewhere? Or am I just getting lucky with the shaking thing :) Thanks!
Also this happens with both burnt and retail DVDs.
OK, now THAT sounds like it may be a problem with either the alignment of the laser lens or just that it needs some lubrication on the rails.
First I would try putting a SMALL amount of moly grease on the rails and the worm gear on the right and moving the laser back and forth a few times to distribute it. Try it out and see if that helps. If this has not been done since the unit was new it is due anyhow. I use a grease in a tube called Lubriplate that we used to use on dot matrix printers.
If this does not solve the problem you can try turning the azimuth adjusting screw in about one quarter of a turn (that tiny screw on the left side of the laser). As time goes by that adjusting slug can wear down a bit. If this does not help you could turn it in slightly more but I doubt you would need to. See part two in this link for a picture and description:
Also you might have luck with the height adjustment screws (those two white ones at the top end of the rails) but usually these are best left at the factory settings. If you do decide to adjust them mark them with a magic marker before hand so you will know where they were originally. These two very rarely need adjusting on the V9 and 10 units though. They stay put better than the older single cog adjustment wheels (like they show in the cyber mag article).
Also I forgot to mention if you have not done so carefully clean the laser lens using a cotton swab and denatured alcohol.
From the symptoms you describe hopefully going through this checklist will straighten things out.
Wow man I wish you were here in Canada :(
Thanks so much for all the details. I didn't do the mod myself so I'm probably too afraid to try this myself ;) I'll pass this along to the modder and hopefully he can check it out for me. If this works it'll definately save me from getting another laser! Thanks so much man!:cool:
