My ps3 fan spins, but slowly and doesn't ramp up as the ps3 gets warmer. This causes any overheat shutdown. 3 beeps red blink. Fan test mode works, and the fan spins quickly then. It must be the fan control circuit that doesn't get the correct temp reading. Could this be a faulty thermal led? (In schematic)
Mine does not charge. The charging chip was really hot so I changed it, it charged one time and now it's the same again.unhooking the battery might help to get it started with the charging
