Doesn't the CD move at ALL I mean any little movement at all? cause if it starts moving somewhat but doesn't boot then your using shitty CDs wich is very rare cause the Saturn takes everything from no name discs from Irak to the finest Kodak discs from utopia
I used to have to tilt my saturn at a 45 degree angle to get it working. Then i discovered that there is a lens alignment screw but you have to take the saturn apart to access it, and the plastic guard which the lens slides along. The screw is to the side of the lens and only needs the tiniest fraction of a turn. But try cleaning it with a cotton bud soaked in meths/alcohol first!
