My little niece was over a few weeks ago and she was messing with my ds lite. After she left, my little bro came to play with it and when he turns it on it just flashes and then turns off. one time he got the bottom screen to show fine but the upper screen was very very dark. Then i decided to buy a 3ds. Now when i try to turn on my ds lite the green power lid flashes and then automatically turns off with none of the screens turning on at all. Is there anything I can do like sell it to gamestop, is it a simple problem that can be fixed? anyone have an idea of whats going on or what I can do? thanks.
