Dead, Power supply OK, no LED1. What's wrong?
Hi
I have an iMac that is dead after a thunder. Now the power supply seems ok, measures 12V and 2V on it, and I ordered another one, as Led #1 do not light up at all. This situation is not described in LED diagnostic order sequence (unless it is the power supply to logic board cable, which I sincerely doubt).
Power supply is singing quietly, other than that there is no reaction to power or power switch.
any ideas? Is there anywhere in logic board I can follow the 12V or the 2V to understand why LED1 is not on?
