20F1 chassis dead. magnavox TV RJ4324
 

I submitted a post a few days ago but didnt get many replies. Is this
chassis a rare one or service manuals are hard to find?
I have this set with a blown 1 amp fuse and a shorted HOT. Magnavox RJ4324
(NAP).
I checked caps with ers meter. none seem bad, no leakers or bulging. No
obvious bad spots on board. No hot spots.
I replaced Hot and fuse but it blew Hot again. the flyback rings good with
my flyback tester.
When I leave the Hot out and turn on the set, The relay clicks in but I dont
get any 130 volt! at the STR30130
I have 156vdc on pin 3, 133 on pin 2 but nothing on pin 4. Pin 4 spikes up
in voltage (over 100 vdc) for a second but drops to zero very quickly, (
like charging a cap). I replaced the the regulator with the same results.
Anybody have a schematic?
Someone suggested overcurrent but I dont even have the HOT installed. I need
to get the 130 volts fixed before I can go any further.
Any help is appreciated. Roy
