Problem with Apple X V, not booting anymore

well, it can also be the solder point that makes it turn on when the power button is pressed. I know you already checked it, i am just handing out suggestions of the possible problem.

If it was static, the chip is probably fried. More humidity would fix it (joke). Hmm, you can always use electrical tape and plaster the chip (well, the new chip if you cannot resolve the problem).

Maybe try to secure the connection to the ground with a little solder. That svrew hole is the ground for most xbox versions, and is ussually what the chips use. If you did not solder a ground point, then it is the screw hole.
