I'm not sure that Apple would cover this unit, since I'm not the original purchaser (was a flea market special), and it seems that the logic board may have been replaced once before already (the original ethernet ID has been stickered over). We actually have two Rev. A iMac G5s with dead logic boards, the other being a 17" 1.8GHz model which, upon startup, exhibits a brief flash of gray on the screen, followed by the fans kicking into high speed after the screen goes blank.
Anyway, for better or for worse, I went ahead and purchased a replacement logic board for both of them from a reputable seller. The question I have now is, are there any specific tricks with regards to iMac G5 logic board replacement? Would prefer to not break anything in the process... -Adam On Feb 3, 2009, at 8:55 PM, Dennis Faulkner wrote: > > I bought two of the last of the G-5's with the old Motorola chips - > one I had, the other is crated up at my mom's place since she moved > far away.
