I have had my iMac G5 for five months. When it is working, I absolutely love it. Unfortunately, keeping it running has been an even bigger challenge than keeping my Windows XP system free of viruses and spyware. I have been experiencing video related component failures on the logic board. The image on the screen starts jittering horizontally, and eventually the display is completely unreadable. Each time it starts, I run the Apple Hardware Test and the Video RAM fails. I am now awaiting my third replacement midplane assembly, which includes the logic board. I just received a new LCD panel as well. When my third midplane arrives, Apple will have sent me $3,750.00 worth of replacement parts for a machine that cost $2,180.00 built to order. (2 replacement midplanes @ $1,289.06 each and 1 replacement LCD panel @ $1,171.88) Replacing the midplane is no small task, either. I have several hours tied up between replacing parts and troubleshooting on the phone with Apple. It seems like this story should strike a chord with anyone unlucky enough to have purchased an iBook G3 covered by the Logic Board Replacement Program. Does anyone have any advice on how to handle this? I fear that each logic board they send me will eventually fail, and the warranty is only good for 1 year. Has anyone else here at MacRumors had similar issues with an iMac G5? Plenty of people on the Apple Discussions board have: http://discussions.info.apple.com/webx?128@764.Zs7YabhYRXe.1@.68a31fdd Edit: I am awaiting my second replacement midplane (not the third). That will be three logic boards total in the 5 month life of the product including the original.
