    I have a white Core Duo 20" iMac that I have very stupidly killed. I had the computer opened up to re-solder the wifi antenna (which had gotten disconnected). I was plugging it in, checking to see if it was getting wifi reception, and shutting it down/unplugging it to make adjustments. All was going well until one time I just forgot to unplug it, was moving the display panel to get a better view of part of the antenna cable, and then POP! it was dead. It won't start up or do anything, so clearly I shorted something out. There literally was a little "pop" sound and that was it.

    I'm not expecting any easy answers or miracles here, but any advice is much appreciated. I really should have just been more careful and double checked that it was unplugged, but hindsight is 20/20. I'm guessing the problem lies with the power supply, so if anyone knows how to replace the power supply (and where to buy a replacement one) that would be fantastic. Any other ideas are welcome too.

    Thanks!

    I don't believe so, but I really don't know for sure.

    What I'm thinking happened is the the metal backing of the display panel accidentally touched the metal capacitor on the power supply and that caused a short. I don't know if that's fixable, or if I need a whole new power supply. And heck, it may even be something else entirely. I'm hoping someone has had a similar experience and knows the best solution.

    take it apart. inspect everything closely. Probably a noticeable spot where it touched. I had a loose screw short out a resistor next to a pci slot on a MDD G4. Machine would not boot until i removed the resistor. I assume the pci slot was toast, but the machine worked perfectly after that!

    I'll definitely do this as soon asap! I'd love for it to be easy to spot like you said.
