DavGoodlin;3241546]Thanks for posting a great symptom video. I saw many of these in Best Western Motels and Holiday Inns when on family vacations in the 70s…
This one could very well be a hotel or institutional set. It has a built in Coax in (75ohm?) near the antenna terminals. Also has a “#6” etched into the plastic cabinet.
I think I will take a deep look into the luminance module, especially the limiter, and will check out the other suggestions. Whats also Interesting is that when the set has a cold start (filaments not under instant on voltage) the pic is entirely green and takes a bit for other colors to come in. Something needs to warm up and i suspect a crt or socket problem. Spark gap a great idea to investigate.
What’s the best way to clean a spark gap?
