I picked up a PS2 Slim from a pawn shop for $5. They said that the disc wouldn't spin, but I decided to buy it anyway and try to get it working. When I got it home I popped the top open and put a disc in, covered the 2 lid sensors and powered it on. The laser moved and looked to be trying to read the disc, but the disc itself wouldn't spin. After checking over the ribbon cables, I decided that the motor must be burned out so I jumped on ebay and ordered another motor. Fast forward to today - I got the motor in and took apart the PS2 again and installed the new motor. I powered it on with the top on and sadly it still didn't spin. I tried taking the cover off and blocking the sensors; same thing - won't spin. Does anyone have ANY idea what could be wrong with it?
