No power, No LED on, No 12v input from PSU
Hello guys,
I have a dead iMac with no LED on at all.
Logic board ID 820-3588, power supply tested OK
power input to power supply OK
tested with new known good power supply
but still no 12v present on logic board.
any advice for this case?
Update :
Tested with normal board and works fine. so the problem is the logic board. Power supply output 0v with original logic board
