My roommate and I have been living together since September. We have it set up to where he uses my TV and I use his refrigerator. But he is ALWAYS using my TV to play his stupid Xbox, and I'm getting tired of being woken up or disturbed by the sounds of bombs from Call of Duty. I DO NOT want to break his Xbox, but simply make my TV incompatible with it. I don't want my TV to accept the xbox, if that makes any sense.

Please help me. I would greatly appreciate any help you can give.

He uses headphones from time to time but he still yells into the mic. Either way, there's noise.
