In other words plug it in & see what happens like you never seen the set before.
I have lost track......

Prev screen shot looked good. But long distance troubleshooting is a challenge !
Many of us could take the TV like shown in the screen shot & vastly improve it
in seconds. That would maybe weed out problems.
Also remember NEVER trust a tube checker. The best checker is a known
good NOS brand name tube. We had an advantage here. I could turn
around & pull a tube from the shelf. It was abt 8' long & 5' high with sleeves of common tubes, more old numbers on shelves in the crapper.

ok first the pic with the face was to rule out the video amp and output by injecting video. Turn it on b+ good few seconds later b+ drops and in doing so the horizontal oscillator won’t run because b+ is being pulled down to far so in using the sets IF cannot get an image weather or not the voltage being draw down has to do with that I don’t know maybe there is an IF problem as well. I have a tube coming maybe this is the problem I don’t know until I get it to try.
