I've never had to diagnose a monitor issue before, so I'm not sure where to start. I can hear the monitor fire up, but it never displays anything. So, what's the diagnosis procedure?

It's a Wells K7000 series.
Start by checking the B+ voltage. Then we'll go from there.
Ok. Let's start over. You have no pic. I'm guessing the fuse is not blown. Next you need to test the B+ on R301. The large white white rectangular resistor on the outside edge of the metal cage. Red probe to one of the leads and the black probe to ground. You should have about 130 volts. The voltage regulator is the IC at IC4 on the inside of the metal cage. Did you test at the resistor or the VR? My guess is the resistor. If you did, 172v is too high. Let me know and we'll move to the next step.
