I got a PS2 from a friend who let me have it because it has a DRE and he doesn't want to mess with it. Anyway the DRE only affects DVD's, Cd's load up very fast.
Anyway here is what I did, called Sony to see if they would fix it, still had warranty sticker attached, they said NO. I then opened up the console and cleaned it out, wasn't very dirty to begin with.
Cleaned the lens with Q-tip and alcohol, didn't work. I was thinking about adjusting the laser angle but this model has 2 white cogs so I didn't really mess with it. If someone can tell me which cog to try that would help!
I then proceeded to the pots to adjust the voltage, pot for dvd was set at 1.3 kohms and I went in increments of 100, went from .758 to 1.517 kohms, 8 different adjustments and nothing. And in a final ditch effort tried 1.95 kohms nothing.
I got tired after this and stopped, if someone can give me some advice to try I would appreciate it. I'm not sure why it stopped working, he didn't say. But when looking around I noticed the tray is cracked, this leads me to believe it may have been dropped. Also the laser model is khs-400c.
