Thank you @nvdeynde for that piece of advice. I have turned that little knob, and for a while, a vague white shape flashed on the screen. If I understand correctly, that proves both the CRT and flyback transformer are working (by the way, there was a spark between the knob and screwdriver while...

I have already resoldered the transformer, yoke connector, and two other connectors. Are there any other joints on the analog board that could be responsible for the lack of picture? I’m trying to rule out as many potential reasons as possible, before I move to more radical solutions such as...
