Yeah, I would've been able to figure that one out. ;-) But I actually
swapped the whole monitor chassis which of course includes the deflection
board, the picture tube, and the HV transformer.

I almost am afraid to ask, but how do I check the low HV? I don't think my
meter goes up that high.

Frankly, I know exactly nothing about monitors. Obviously rechecking the
connections is a good idea...

Me too. Is this easy to fix? Are parts still available?

Thanks for the advice!
