I have a 15" iMac G4 that I took into the Apple store for repair. The unit wasn't powering on and I figured that it was the PSU. The Apple tech also said it was the PSU so they quoted me a price of $250 for the replacement parts and labor. I agreed and now they are saying it isn't the PSU but the logic board which will cost $480 parts and labor to fix. If I do nothing and take it back they will charge me $92. I figure the iMac is only worth about $500 so i am not sure if this repair is worth it. What do you guys think? Is there anywhere I can get it done cheaper that is reputable? Should I just get it back and sell it for parts as everything else but the logic board is fine? Should I fix it? I should also say that if I fix it it was intended to replace my daughters iMac G3 500 so it would be for her not me. I guess I could sell the iMac G3 to try and recoup some of the cost but that isn't about to net me much of a gain. I am so frustrated now I wish they would diagnose the problem better at the apple store! Thanks for any help.
