My PS2 Slim SCPH-77001 is not spinning at all. When I close the lid it says "reading disc" for a second but then it just stops and the disc just simply won't spin. I already pushed both sensors with a disc inside and it just won't spin. Although the laser does moves but only when press the back sensor, but it doesn't light up at all. Since my laser moves like it normally does but it doesn't light up a red/blue color or anything, do you think the laser is the problem? I had to change a laser because the old one was not reading anything dvd silver games and I just remove the blob from the new laser.. what do I do?
