once i get one of these mine is going to be an everyday watcher.

I will have to find my schematic and see on that question. I will throw this out there. I found that there is a video detector diode in mine which seemed to be a problem and the coil that I belive was in series with it is open. Problem for me was that the video section was not what I was battling. No, or very little vertical height and a volume adustable hum for sound is all this set had before and after a recap. I just never figured it all out with little time and no test crt or a scope for proper troubleshooting. Without a test crt there is no way to check test points with a scope. Some test points are on the surface I think on those connection points/strips.
