I replaced the upper screen of my DS Lite and everything is working fine except that when I try to close the screen, the DS turns COMPLETELY off when the screens are aligned at a 90º angle. If I try to turn the DS on with the screen in that position, the battery led flashes a second but nothing happens. I also noticed that if I move the screen a little bit, it flickers. I read that the DS lite has a sensor in one of the hinges (don't know which one) that triggers sleep mode when both screens are close. Could that be it? Can it be fixed? It's A BIT annoying... Thank you.
