iPod won't power on after screen replacement, even when plugged in
I just replaced the screen on my iPod, tearing the copper tape on the back of the rear camera in the process. When I first tested it, the power button didn't work—but it turned on after I plugged it in and worked fine. I disassembled it and found nothing wrong with the power/volume ribbon cable or anything else. Upon reassembly, it will no longer power on at all, even when plugged in. Any ideas as to what might be going on here?
