So apparently something strange has just happened to the DS Lite that me and my fiance share (more so him). Out of nowhere, a horizontal line of pixels near the bottom of the bottom screen has started acting screwy. They're not dead and they're not stuck on one particular color, but they are never the colors they're supposed to be. When the DS starts up and goes to the system menu, the line is pinkish. When playing various games, it's usually black, but sometimes it's other colors and sometimes the line isn't all one single color.
It's strange because we've taken very good care of it. We have the best looking bottom screen of anyone we know (and we know plenty of people with DS systems). There isn't a scratch on it. Probably the worst it's gone through is a couple very minor falls, and my fiance occasionally takes it in the bathroom and leaves it in there while showering which makes it a little moist from the steam when it comes out. This problem didn't occur remotely near those things happening, though.
It's too old to fall under the warranty, and according to him, Nintendo charges $75 for a repair, which seems absurd to me. So does anyone know what could've caused the problem and what we can possibly do about it?
