Pull out your meter first and check the monitor's DC voltages.
They're the first things I check. Get a copy of the schematic,
locate and measure the +9.1V (regulated), -9.1V (reg), +55V (reg),
+63V (unregulated), -63V (unreg) and the +126V from the voltage
doubler. If these are OK then check the 100V on the Hi-Voltage
regulator board. From there, check the 22.5kV when it's working.
The Zektor manual on-line has more voltage test point values on pages
36 and 37.
