Hi, yesterday my son played a game ( i think the latest star wars game) wih the dstt card and the game froze. He closed the lid and turned the power off. Later he tried to turn on the ds again, but he only got a green ligth and 2 black screens. i tried it several times myself. I also unplugged the dstt card. no success. i pluged in the battery charger and light went orange as always. today morning the battery was full and i tried it again. after several tries the screen went on and the ds menu was loaded. i turned the ds off and turned it on again. ok the ds is running again. my son was happy. maybe 30min later the ds made the same problems as before ---- no booting no screen. where is the problem ?
