A slightly different approach to fixing the Disk Read Errors associated with Fatty PS2s.
Sooo no, this is not the home made airsoft shotgun tutorial I've been promising. This is a little thing that's happened along the way.
My PS2 died on me the other day.
I had just played through GTA: San Andreas. Near the end it was giving me some clicks and a Disk Read Error screen from time to time. But it always seemed to catch up with it's self and let me play longer.
It started giving me more and more trouble with movies. I would get loud clicking, sometimes grinding sounds, until finally, it crapped out completely.
I knew there had to be something I could do. I had seen replacement components on places like Deal Extreme, so I figured there had to be a fix. Instructables was the first place I looked.
Not much help here. Just a tutorial that mentioned cleaning the laser eye which I very much doubted was the problem, considering I could definitely hear mechanical clicks.
I searched around the web and found lots of guides, but all of them were stuck on the idea that the laser eye was dirty and cleaning it would allow the system to read some games but not DVDs.
A few mentioned that the laser eye's height might have been misaligned, and because of this, the gears couldn't grip the gears of the motor or some such bollocks.
They said you need to rotate the gear that adjusted the laser eye's height.
And here came my first problem. The models they showed had one white gear right in the middle of the assembly, which mine did not have.
They also said that this fix was unlikely to get it to work with all games and movies. Likely just some games.
Finally, I found another that mentioned my model with two smaller gears a little deeper inside that did the same thing.
Me being a genius, and usually drinking while I tackle projects like this, ignored the part where they tell you to mark the position the gear was in from the start. So I thought I may had screwed myself from the get go.
But onward I went. I did as they said and tried different heights for the laser eye until the third try where I had no clicking and it seemed to read the games fine. However, when I put a movie in, it would start clicking and if it could see it all from the start, it would soon give me a disk read error.
So for the past couple days, whenever I felt the gumption, I'd sit down and adjust the level click by click. Replacing the housing for the laser and powering it on to test each time.
This was not fun.
It still didn't add up. Why would fixing the mechanical problem the way they said to do it, fix it for some games but not for movies? Obviously some thing's not being fixed.
I sat back, cleared my head and thought about how else I might be able to go about this..
One of the tutorials had a note from a supposed former Sony tech that said the rails the laser eye rides on and the threaded shaft from the motor that it's attached to need to be oiled. This makes sense.
I oiled it and tested it. Still clicking.
Then I tried to see if I could physically move the laser eye from it's current position. I found a way to do it, closed it up and it started working like a dream.
I don't know if it's because moving the eye worked the oil into the system enough or if the gears were able to catch properly. But for whatever reason, it seems to be reading games and movies perfectly without any clicking.
So. Now that you've read through my dramatic personal account of the ordeal, it should make for a fairly uncluttered tutorial.
Onward to the first step!
Step 1: What You Need!
1-Jeweller's Screwdriver kit. Particularly the small Phillips(+ shaped) heads.
2-A larger Phillips head screwdriver. (like the one on my leatherman)
3-Allen Key. (I have a set. It doesn't give me the measurements for the size I used. It may not be needed at all)
4-Machine Oil (WD40, I used Silicone Oil. Don't know if that's a problem. Come to think of it, you probably shouldn't use silicone oil.)
5- Duster Gas or something to blow the dust out of it with. I would not use a vacuum.
Oh yeah... DISCLAIMER!
This may mess up your PS2 worse than it already is. This is just what I did to rescue what was otherwise a write off.
I also don't know exactly why this worked. I have my theorys, but I can't say for certain, and I don't know how long this is going to work for.
Also, as mentioned in the intro. My PS2 was a later model of the Fattys. SCPH-50001 to be exact.
The internals might not be the same as your fatty PS2. But I still say you go through it, read what I did and see if it jives with what you're seeing inside yours.
