Laser reads blue disc but not white disc????
 

My PS2 version9 SCPH50002 reads Blue Disc ok now. But when put White Disc in it does not read. How do I fix this? I've already tried adjusting the pot by lowering the resistance and it still only read blue disc..Thanks.:confused: :confused:

POT adjustment doesn't always work... sounds like the DVD Diode in the laser was either completely blown to begin with before you attempted to adjust or you over-adjusted it... :(

The Laser was already reading Blue disc only before I even work on it. Must be a blown DVD diode then. You mean I need to replace to circuitry under the lens??? :confused:

No. You need to replace the entire laser pickup unit...
