I have iMac that does not boot. The power supply gives 12v. No response to the switch. I am looking for a schematic and boardview.

PP1V1_SLPS2R 1.1v
PP1V8_SLPS2R 1.8v
PP1V2_AWAKE 1.2v
PP3V3_AWAKE 3.3v
PP1V8_AWAKE I connected the board directly to the 12v power supply. not sure how to explain it but sometimes it is 1.8v and sometimes it is absent.
