After fully disassembling my first generation iPod Touch several times today, it isn't turning on or charging. No parts were replaced; I was merely trying to reseat the fidgety home button. I had previously partially disassembled my iPod before, but had never gone far enough to remove that small logic board referred to as a PCB by iFixit.

In the process I bent it ever so slightly.

Took it apart again, placed shield back on, and reassembled the whole thing. It was at this point that the iPod refused to turn on, or even charge. I should add that the first time I disassembled this iPod several months ago the same thing happened. No response for several hours until I got home and plugged it into a charger. I'm guessing (not to mention hoping) that this is another case similar to that first time, because it would not have otherwise turned on immediately after a reassembled it the today. If the PCB is broken, what are the chances that I can replace it? It's attached by two flex cables to the main board, a connection I have no idea how to replicate.
