Well, after a few months of sluggish performance and random hangs, my kitchen iMac G5 decided not to start up. The screen is scrambled at boot then gets to the blue screen with video artefacts until the fans start revving up. Nothing advancing to the desktop. I opened up the iMac to look at the diagnostic LEDS and the three green lights were showing normal power and communication. However, I noticed two of the many capacitors were blown/leaking. Reading up, I found out that the iMac G5s were plagued with capacitor issues and the repair program unfortunately ended in 2008. Now, in my research, I've been seeing repair costs of about $200 for replacing all the capacitors on the motherboard. I don't know what the local Apple Repair depot will actually charge. Replacing all the capacitors might not even fix the machine if the CPU has been over-heated. So at this point in time, is it worth repair this machine??? What do you think? Has it served it's life cycle in its eight years?
