I have a 3-on-3 open ice arcade game and when I start it I can hear it starting up but I get no video. The monitor seems to be getting power and the board works fine....even tried a different board. and I could hear it running..just no video... What do you think?
 
explain why the monitor seems to be getting power

have you metered it?
do you have neck glow?
static on the tube when on?
 
I can hear it humming......on the screen when I turn it on/off I can see a flash of white. When I unplug the monitor from the power supply it does not make a hum...
 
Check the voltage to the monitor, then check that the video connector is still connected, then try turning up your brightness. If you still get nothing, then your monitor needs repair.

It's also possible that you can get brightness raster to turn up and still get no picture. I've had a Ceronix monitor do that once....
 
You use a DMM (Digital Multimeter), set it to AC 200, and measure at the power connector to the monitor. If you have two wire, put a lead on each. if you have three, measure between the ones that are yellow or green...
