I'll second that. It's what I was going to suggest also. Just put it in one of the kid's rooms, or some other out of the main area spot.
Another thing to think about is the sleep timer maybe? If only there was a way to make the TV turn itself off after, say 2 hours, and it's always set this way when it's turned on automatically.
Since, I've never used a sleep timer, I don't know if that is possible.
"Fist time the TV is left on overnight, is the last time you'll be playing games on it.". Some kids are just too stubborn for this to work, though. Give them a year, without games, after the first offense, then see if this works.
