Buck,
These sets are famous for leaks.....there is a kit from Zenith which
handles the problem. Call them for a repair kit ( should be free!
888-393-6484. A far as the shorted H- output fix. Hv block & fly are prob
OK. Inspect the CRT drive boards for burnt parts & shorted resistors.

ZENITH 9-1978
Set Comes On With Sound But No Raster On Any Of The Tubes
Chambers Electronic Service
Replaced H V Block A-17196-05, Qx3200 And Crx3412 Restored High Voltage And
All Three Tubes Came On
---------------------------------------------------------------
ZENITH 9-1978
Video No Go - High Voltage Ok
Check R3244 / 8.2k And R3243 / 110k Both 1/2 Watts On 9-1978 Module
---------------------------------------------------------------
These are funky sets to work on.........kind of a bad place to start with on
projo's. Fix the sweep module....contain the leaks & you should be all set.
