Pinout voltages, No 12 volt on standby
Just tested my dead iMac Intel dual 2.4Ghz PSU.
It currently doesn't boot, no signs of life. After looking at the pinout voltages on here I see pin 8 should read 12V. I have the 3.6V on pin 5 but no 12V rail.
Is it likely the PSU is shot.
I had somebody elese test it and they said it was OK but I am wary of their motives. i.e. Replacing the logic board as a repair instead of swapping out the PSU.
Any pointers would be great.
Is this a good question?
