Did you turn up the contrast knob all the way (both ways)? Did you look for a glow coming from the back neck of the monior?
Damn. Well only thing left to do is trace the power coming into the monitor. Don't attempt this unless you REALLY know what you are doing and are at least an intermediate level electronics guy. Make sure 120V is at the inputs and follow through the 2 fuses (which you said are NOT blown).
I'm afraid if you see no glow from the neck of the tube, and the fuses are not blown, then the tube itself died (maybe lost vaccume). You may be able to salvage the board/chasis. If you had another similar type monitor, maybe you could try swapping the chasis. Unfortunally this would require you to rip the monitor out of the cab, and desolder a few points to disconnect the board.
Not for the beginner/tinkerer.

: I connected the monitor to one of my arcade boards. Nothing happened. I turned off the lights and looked at the tube when it was on and there was no glow.

: : Sorry for the obvious troubleshooting questions: do you have anything else you can hookup to this monitor to test it out? If it was working one day, and simply not the next day, could it be the PS scart cable? I hacked a PS scart cable to my monitor and it STILL gives me problem (because the PS connector end had its pins pop into the casing if I push to hard...it simply wasn't making contact. Also, have you tried turning up the contrast all the way (to see if get a glow from your monitor..look with lights off). Don't touch the red/green/blue knobs.
: : You say you hear that the tube is on...from the back, do you see it glowing in the neck part of the monitor?

: : : Help, my monitor is not doing anything. It has power and the fuses are good.
: : : When I turn it on, there is nothing happening on the screen. I turn on the monitor and I hear a high pitched noise. After I turn it off the noise lowers in pitch then fades off.
: : : Any Ideas out there??!
