Max,
Remove output transistor... Plug set in, see if you have 130 volts on
collector tab...If no 130V troubleshoot power supply.. With 130V you could
have shorted fly... I would remove the sweep board and resolder all regulators
diodes etc.... Make sure you resolder all of the pins on the cable plug sockets
to other module..Not sure about this model but there was a Zenith model, if
horiz drive lost, output transistor shorts at turn on..
Hope this helps..

I found the HOT shorted and replaced it with a 121-1148. When turned on
it shorted out again. I have a schematic that is close.
Any suggestions are welcome.
