    I got an old G4 from eBay that was having logic board problems. This afternoon I took off the bottom plate to try to re-solder the chip that seems to most commonly be the problem. After completing the procedure, I put the heat shield back on the bottom to protect the bottom of the board to flip it right side up. I plugged in the power cable and I pushed the power button. A spark flew from the metal frame to the heat shield and everything went quiet. The adapter is no longer glowing and I can't get any response. What have I done and is it fixable? I'm super bummed, so any help would be enormously appreciated.

    It sounds like electricity found a shorter path to ground. That would be the spark you saw. You probably fried it. Who knows where that electricity went and what it destroyed when it got there.

    Maybe you're lucky and someone else knows more than I know (plenty do).

    After sitting for a while, I gave it another try and I was surprised that it started working again. The screen still won't turn on during start up, but it's powering up again. I'm not sure how to get the screen to come on, but having juice to the machine is a good place to start.

    That's quite impressive.

    Have you tried hooking up an external monitor?
