I need some help with a PS2 laser and dvd drive mechanism. I have PS2+messiah with a poorly adjusted dvd drive: The white cog was not adjusted The azimuth screw was replaced with a new laser I am assuming the newer laser from lik-sang is preadjusted so i am not going to touch the POT screws. My PS2 reports a "No Data" error and clearly doesn't see discs (DVDs, CDs, DVD-R, +R, CD-Rs). The is moving along the tracks fine and the disc does sping but only for a brief moment. If anyone can give me some suggestions i would be grateful.
