I recently added new housing to my NDS Lite. When I try to turn it on, however, the green light goes on, and it tries to power up, but the top screen blinks white and the whole thing just shuts off. The ribbon cable isn't damaged, and it's in as far as it can go. The mic and wi-fi wires are in correctly. I've disassembled and re-assembled everything, and this still happens. I can't figure out what's making my DS do this. Does anyone have an idea as to what's wrong? Thanks!
