I just bought a 20gb backwards compatible ps3 off of ebay. i plug in all the wires and cords (2 of them), flip the switch, and turn it on. The light turns green, then switches to yellow, then to red, and just blinks red. the fan turns off. I try putting a disk in, and there’s something blocking it. Cha Cha said it had something to do with corrupted memory, and some website said that it was “CPU failure,” or something like that. Can anyone diagnose my problem, and hopefully tell me how to solve?
