I  can power it on with sound, recieves cable, stereo led indicates 
stereo signal. No HV.
A few checks:
H. driver transistor Q703 has +124 VDC collector.
HOT (?) Q704 no B+ at collector. Is NOT shorted, has diode action with 
meter.
 Large cap C904 has +122VDC.
 Flyback pin 9 "B+" has no voltage on it.
Connector GB pin 3 has zero volts. (seems to be a B+ piont)
BTW this seems the same as the PPP400 and PPR500 models. All Hitachi 
VP6X chassis.
Any notes ?
Thanks,
All for now.
