I had a DS lite with a broken hinge and ordered a new case/kit to fix it up. Before putting the case back together, we tested the touch screen, and it worked perfectly. After putting the case and everything back together, the touchscreen stopped displaying properly and now all I get is a blank white screen. It works otherwise. I can start up a game, press buttons, etc, just doesn't show anything. I'm not sure what went wrong or if I'm out of a working DS lite now. Any ideas?
