I have a fat 40gb Playstation 3 that I was tasked with fixing. The problem I cant seem to figure out (aside from replacing the drive) is: The disc drive does not engage when a disc is inserted.The Playstation does however, turn on if it is off when I slide a disc in (hitting the trigger switches)If I put a disc in the drive (while the drive is disassembled) and hold down all the trigger’s, the drive does not spin up and the laser does not turn on.since it doesn’t seem to get a signal about a disc in the drive, I cant eject. just the double beep comes from the playstation. So I am left wondering what is up with this. Should I just replace the whole drive? I don’t have a second working drive that I can use to test if it is something coming from the motherboard..

Benjamin Shefte it does sound like it all comes back to the drive. I would go ahead and replace it.
