bruce--i should have thanked you for the link. i found my way to badcaps.net, a very interesting site.
i removed the power supply, and tested the outputs. i got 11.56v on both "12v" outputs. that leads me to believe the problem is with the caps on the logic board, which there is a kit for on the above site. i'm considering whether my soldering skills are up to the task. btw, the person that gave me this kept the HD, but also kept the temperature sensor that is glued to it. will the computer boot without the temp sensor plugged in? if it won't i will try to find a pinout for that connector and make a jumper. thanks ken On Jan 2, 7:41 pm, Bruce Johnson <john...@pharmacy.arizona.edu> wrote: > On Jan 2, 2012, at 4:03 PM, faithie999 wrote: > > > which are the "power supply" caps on the logic board? there are > > probably 20+ caps in all on the board. > > Follow the links I sent, or google "G5 iMac capacitor replacement". > > If you're kitting up to do the power supply, may as well do the whole thing, > Power supply and logic board. > > > > > as for the power supply board--did you replace the large caps, or just > > the smaller ones? > > Only the big can-like ones > > > > > i know that any of them can be bad, but desoldering and resoldering > > the larger ones are probably beyond my capability. the smaller ones > > look doable. > > Actually the larger ones are easier to remove. > > -- > Bruce Johnson > > "Wherever you go, there you are" B.
