[quote name='tayaf69']The tube is broken...Does that mean that all you have to do is replace that? Aren't they just tvs? That'd be awesome if that was the case. Through a new screen, a computer with all the good games (The Simpsons, etc.) and your set.
Obviously there is more to this though...[/QUOTE]
They're not just TVs, it's an RGB CGA monitor (not CGA computer monitor). 15 hz, so half the scanlines as a computer monitor (I belive 31 hz) and different from a TV (but I forgot the exacts). You'd be better off replacing the monitor, it'll cost you about $200 for a new replacement monitor (betsons is a good place to get it). You need to wire it up though, so be prepared to soder.
