Replacing a monitor

[Cinder6]

So, I can buy a Killer Instinct machine for real cheap--the only problem is, the video doesn't work. Assuming it's not just a simple connection problem and the monitor is busted, what monitor will I need? And, where's the best (as in cheapest) place to find one?

Thanks

EDIT: Video, not sound

Sound has nothing to do with the monitor. Sound comes from a speaker which has wired that go to it from the board. If a game has no sound you either have a board problem, a speaker problem, or a wiring problem between the two. I guess theoretically you could have a power supply issue too but I've never personally seen that.

Whoops, meant to say video :|

Well, depending on what's wrong with it, your best bet is just to fix the one that's in there already. Or you're looking at ~$400-$500 for a new monitor.
