I've had my ds for a while now, and last week it started giving me problems with the top screen. After a few minutes it went back to normal, and when i turned it on again there was no screen the only thing you can see was the pass me screen although it was flickering. I never dropped the system or anything like that from what i can remember, but the only thing i can think of would be a small crack that began in the unit a long time ago. As time passed it just got bigger even though it still worked, so im wondering if this hinge problem that everybody has been having is the cause
