The TP for the main B+ is the cathode of a diode, off the SMPS transformer.
( rear edge of HV PCB ). There may be other diodes off it to run lower
level voltages. The main B+ can be 120 - 140 VDC depending on the set.
Also on the right edge of the HV PCB there is a big black cap. I think its
one of the trouble makers. BUT its been a LOT of years ! The
top vert problem may be another 'lytic IN the vert out. Find the main
problem first. There is probable a beefy diode in the PIN thats in the
hoz out area that shorts on many brands. Lift one end to test.
