So my PS3 just turned off on its own while I was playing NCAA 10 yesterday. Only played for about 20 minutes, wasn't hot at all.
Getting no power, no lights, nothing.
Out of warranty so I pulled the thing apart, started checking everything with the handy multimeter. Cable is good, switch is good, primary side of PSU is good. Secondary side is the weird one. With the 12v prongs and the 5v plug both unplugged, they get voltage, but as soon as I plug either one, or both, in, the whole secondary side has no voltage. Then when I unplug them, voltage magically returns.
Any ideas to what part of this PSU is bad?
