If you have neck glow, chances are you HV transformer is ok at
least. Most likely if its a problem with the HV unit, it turns out to be
the HV diode. You could verify the HV with a HV probe, but most people
don't have these (except us serious vector monitor repair nuts ;-))

Oh, and cracked header pins on the deflection board's 10 pin connector can
also produce this exact same scenario. Sometimes I forget to mention
these common fixes because whenever I have a vector monitor in my
posession, resoldering the pins, recapping the monitor, etc are standard
operating procedures.
