symptom:
when power button depressed, pilot light comes on for 1/2 sec, then fan at full speed for 1/2 sec, then powers down.
i dissassembled the imac. no obvious swelled or leaking caps on the logic board or power supply.
i read this thread: https://www.badcaps.net/forum/showth...light=614-0394
and my PSU is the one pictured in post #4.
the fuse tests good.
when connected to AC, i get 11.56 volts across black and gray (both sets of black and gray) and negligible across black and brown (makes sense if brown is an input contact).
are there any diagnostic LED's on the logic board that i can refer to? googling reveals that there are on the non-isight 17" but i can't find reference to any on the isight version.
any other ideas?
thanks
