Hv comes up wave form looks normal at collector of HOP xstr. Plays for about 5
seconds and shuts down.
Have pulled the pic tube socket. The B+ is 127v at the HOP xstr. The scvreen
voltage is only 6v. Bad IHVT?
Screen voltage winding shorted ? It is not burning. Maybe isn't on long enough
to burn? Paul
