First off, I'm a total newbie when it comes to arcade monitors. This'll be readily apparant soon enough.

I have a 25" Wells-Gardner 25K7191. It
appears to pretty much be the same as the W-G K7000 series.
The basic problem is that there is just plain does not power up. Everything is hooked up, and the line feeding it from the isolation transformer is putting out 120V (I tested it with a multimeter). I tried changing the fuse on it, but that didn't help. It appears to be getting NO power at all; absolutely nothing happens when I turn it on.
So bearing in mind that I'm a n00b when it comes to arcade monitors, what else can I check on?
