Like many others, I have a G3 iMac (specifically, 400mhz iMac DV) that suddenly, mysteriously stopped working.
It seems a well known problem. My situation ranges from "similar to" to "identical to" these:

Yes, I've tried the new battery, pmu reset, upside down boot, etc. No luck. Many posts I've read, here and elsewhere, somtimes indicate the culprit to be a bad "PAV board" - other times a bad "power supply". My main question is, is the "PAV board" and "power supply" referencing the same part using different terminology or are these 2 different parts?
- If these are 2 different parts, which is the one that is most commonly known to go bad on G3 iMacs?
- I have access to a few tray-load iMacs. I realize many (probably most) parts are not interchangeable between the
tray- and slot-loaders but might anyone know if the power supply or PAV boards are.
- On all these malfunctioning PAV boards (or power supplies), is it always/usually the same component that fails?)
- Thus far, I've not been able to find any but might someone be able to direct me to any available documentation pertaining to step-by-step disassembly instructions to access the power supply, tests/voltage readings to confirm if it is problem, etc?
(Yes, I realize I need to replace it with a newer Mac. Regardless, I still find this useful and, if possible/practical, would like to repair it.)
Thanks for any help
