Thanks for the input.. Update.. Replaced many caps in power supply, removed
vert output, and opened horizontal output....... When power button is
pressed B+ goes from 47V to 110V but within a second drops back to 47V and
HV never tries or goes up. Seems like all the supply voltages start to go
up on button push, but also drop back. Will post when and if i ever find the
problem..
