The flyback sounds a bit strained which is worrying, and the tube inside the flyback housing is not lighting up. Voltage is going through the wire that attaches to the top of the tube though.

Any ideas on this? I do not have a tube tester so I am mostly looking for a way to troubleshoot this if the tube is not the issue. I got this tv from the original owner and have really been trying to fix it to show it to him. His health is declining so I am trying to get this project done as soon as I can.

Also keep in mind I have never really messed with tubes. I do repair on vintage solid state audio so this is a bit of a stretch.

Recapping is best done in stages.
When first testing, you have to observe the operation!
With a signal: Is there sound and some kind of image on the screen.
Knowing that set, the horizontal will be off frequency, the vertical circuit will be producing a miss-shapen screen, both common problems with that set.
