Default Panasonic dead set

Hello all: I am working on a model# CT32SX31E

When you press the power button the relay clicks, and nothing! VDC at
collector of horizontal output is 139 volts Found a 0.1 uf electrolytic
cap near IC101 reading an ESR and a 22uf electolytic cap reading ESR above
normal. I neglected to get those location numbers, anyway the set was
blowing the main fuse before I replaced them. Now the fuse is OK and I have
a B+ of 139 vdc at the collector of HOT I still have a dead set. Is IC101
a common failure on this set? Any suggestions would be greatly appreciated.

Thanks

Dave

TAFT HAYNES:
Verify that H.start-up pulses are getting to the base of the H Dr xstr when
attempting to power up.
