simple things first
does the neck of picture tube glow?
No.
have you checked all fuses?
Ha ha! No, I haven't; I wouldn't know where to start. How many fuses should I find and where? Fuses that are burnt out will appear opaque and discolored, correct?
And, I'll try checking for the make and model of the monitor. I'm pretty sure it may be the original because it seems fairly old: Looking with the right angle of light, I can see "burnt in" images on the screen: "Game Over", "Score", etc.
I was just hoping that it would be possible to repair the thing; it would be a shame for it to be trashed. As things are, I'm pretty surprised that it hasn't been already: it sits in a dorm lobby next to a big screen T.V. that's probably not half as old as the arcade cab, and it's trashed beyond repair.
