My ps3's blu-ray drive died on me. Sony wouldn't honor the warranty, so I decided to take it apart and see if I could diagnose the problem. I noticed that the drive motor isn't turning at all. From my experience when a disk is inserted into a drive, even if it doesn't read the disk, the drive motor usually gives a couple of quick little movements. The laser lights up, and goes back and forth on it's shaft, just as it should, but there's no life from the drive motor. The motor seems to turn by hand fine, so it doesn't seem to be seized up in any way. Does anyone have an idea of what part of the drive is bad?
