It's anyone's guess without a schematic and voltage measurements.
Another possibility is if the CRT gets it's G2 bias from the B+ boost system and the boost diode and or filter failed that could cause no raster till shutdown. I had that problem on a roundy color TV once.

I searched and searched for anything on this monitor. I tried the suggestion of FCC ID, etc. Found nothing there that would indicate it being anything other than a CRT device. So finding a schematic is out of the question.
I will redo all the voltages as it now has a signal. Hopefully they will be different than when there was no signal.
