I have a Prisoners of War game that I have in a 24 Hour Mexican Food Restaurant in Phoenix, AZ and after a few weeks the monitor stopped working. I opened up the back and the power seems to be find and the JAMMA board seems to be working as well because I can hear the sound of the game, there is just no picture. From what I can tell the fuse on the monitor circuit board looks good but I have not tested. I have been told that the monitors can be extremely dangerous, so I am very reluctant to get close to it. Any help would be greatly appreciated.

P.S. It is at Juliobertos at 3rd Street and Dunlap in Phoenix, AZ. If you know something about monitors and would want to meet up there that would be awesome!

Looks like a typical K7000. Easy enough to work on, parts readily available.
But in order for anyone here to help you'll have to be comfortable enough to pull the chassis out. (discharging the monitor, etc)
Either to walk you through it, or to send it off to someone. (soldering a must if you want to fix it yourself)
There may be someone in the area to help ya, but I can't say who exactly.
 
one of the things you have to watch out for is discharging the monitor tube.
the K7000 has a degauss circuit and it wont zap you if the circuit is working.

you might want to get into the habit of doing it anyway, just in case. some keep the charge and will bite you real hard if you arent careful.

heres a site that can help you:

oh, and welcome to the show!
 
I have a k7000 aswell, and once I moved the cabinet and one of the wires off the isolation transformer came off and I had no screen like you describe. might want to take a look at the bottom of the cabinet to see if any of those wires came loose and I would also replace the fuses for the monitor. I think there should be two fuses for the monitor and 2 fuses for the power. atleast thats how it is setup in my cab. and im not talking about the fuse directly on the chassis, but the ones you see at the bottom of the cabinet. then I would look into removing the chassis if none of that helped.
