I did search the forum for a while on this, didn't find anything useful.
A friend at work gave me his slim PS2 (SCPH-70012) to fix, it's got the old "reads CDs but not DVDs" problem. Cleaned the lens, tried playing it on it's side, all that other "quick n' easy fix" type stuff that never works anyway. The slim PS2 doesn't seem to have the gears and potentiometers to tweak as the old PS2 did. (or am I not looking hard enough?)
The mechanics seem to be okay, sometimes it seems to work really hard to try and read the discs, and like I said it plays PS1/CD games without problem. Oh, and the message is "There is no data" as opposed to "Disc is damaged or dirty", etc.
So is my only option to replace the laser? I've seen them for $10.00 plus some insane shipping price on the Bay of E.
