Idk if this is an xbox problem but i can't find any other place for help. So I was playing a game and my screen just went black but it wasn't full black, it was like a dark grey black if you know what I mean. I have unplugged all the cables and plugged them back in and did nothing. Sometimes it would display the splash screen or whatever it's called for a spilt second and then go black again. The game was still running and there was sound, I just couldn't see. Does anyone know what to do?
