I found a loose wire and broken resistor lead on the contrast control. I wonder if that's what caused the set to stop working ?
Only one way to find out
I used a 150W bulb in series and slowly brought it up on a variac. Just a little crackle from the speaker.
I plugged the set directly in and was treated to some sporadic flashes of light on the CRT accompanied by arcing sounds. I checked inside the flyback cage but didn't see any arcing.
Next, I wiggled the tubes and the arcing clear up.
Here's the first stable raster.
I hooked up an antenna and was able to pick up a local LP station on channel six but no sound.
Then I hooked it up to cable. More tube wiggling and I have sound
It's weak though and I have a lot of horizontal tearing.
Not bad for a first power up
