Zenith 19EC45 Vertical Problem?

[jblmar]

Thanks Charles.
Repaired the problem last night. C908 measured 0 mF. That cap should ground the Vertical Blanking transistor to turn it on. The transistor wasn't conduction.
Thanks to all for your help and input.
A special thanks goes out to JSTOUT66 for his generious offers re replacement boards for this set. If anyone needs replacement boards, JSTOUT66 is the person to contact.
Charles. The picture is fantastic. This is the 19EC45 25" Picture Tube. Cleaning of the tuner along with all pins on each PCB will result in a great picture.

A note on handling the Vertical Output PCB. It's very easy to touch the Vertical Centering or Size VR while handling the PCB for inspection. Upon completion of a repair/inspection, check to see that the picture is centered while observing a program containing CC pulses. Watch the TVs tuner, not a tape or disc. Most CC is either on the top or bottom of the screen, hidden behind the frame of the Picture Tube area. When I put the set back together last night, the CC pulses were visible. A slight 'touch-up' of the Vertical Centering control fixed the problem.
