Is my psu dead? iMac won't power up.
Recently my iMac won’t power on at all. I opened it and noticed that none of the diagnostic lights are powering up. Not even the 1st led. I tested the psu with a multimeter on the psu pins. pin readings are shown below:
Pin 1 - Ground
Pin 2 through 4 - No voltage
Pin 5- 12.04v
Pin 6- No voltage
Pin 7 - 3.315v
Pin 8 through 9 - No voltage
Pin 10 - 3.315v
Pin 11 through 15 - 12.04v
Pin 16 - No voltage
I also checked the power cord and small cable that connects to PSU and it has power going through them fine.
I would like to know if my iMac power supply is dead, needs to be replaced or is it another issue? Any help would be greatly appreciated.
