    Hey guys!

    I have a great shape iMac G4 (the 15", 700MHz model) that is refusing to power back on. It was working perfect till a few thunderstorms and I guess it is related.

    Pressing the iMac's power button doesn't feedback in any way - no sound, no lights, no screen, no fans, just absolutely no feedback. This led me to think the problem is the power supply unit. I want to fix it myself but after finding out that part could cost up to a 100$, I'd like to make sure that this is actually the problem.

    Do any of you guys have any knowledge to share of how I could be sure that the power supply is the actual broken part?

    Thanks a lot!!

    There's really no good way to make sure the power supply is actually the dead thing. But, in most cases like the ones you are describing a dead power supply is the problem. Have you tried resetting the PMU?

    Yep, tried, nothing. Also did some voodoo whispering while doing that. Still nothing :(
    You're probably right there's no way to be sure. But - can you think of anything else? (except, well... the logic board...)

    Where are you searching for a new power supply from?

    My first try was to look on ebay. I live in Israel so I need a supplier that sends worldwide.

    Your location could be a problem to getting one cheaply. May I suggest also looking for a complete G4 iMac? You may be able to get a better one for a smaller price than just a power supply. But if you get a whole iMac just for the power supply, make sure you get the same model.

    You're probably right. Bummer.
    Well, I'll try to look for a wandering old iMac, or a cheap bargain on the power supply unit.

    Thanks anyway friend!
