We purchased our iMac G5 on December 20, 2004. In 2006, the logic board went out and was replaced under the Apple Care warranty. This past summer, it started having problems again. I took it in and they told me it needed a new logic board, but after bringing it home, all was fine. Fast forward to last week when I turned it off and it never powered up again. I did the LED test and the 1st light turns on, but not the second. I have an appointment at the Genius Bar on Wednesday, but I know they're going to tell me I need a new logic board and I'd be better off just buying a new machine. I don't want a new machine. Or, I don't want to PAY for a new machine. Why would a logic board need replaced 2 times in 2 years? So, thoughts? What recourse, if any do I have? Am I out of line in thinking that replacing a logic board twice is an Apple problem and not my problem? Thanks for any suggestions.
