If OK, try another 30, try longer, and so on.

Ok but what am I accomplishing I already have good video at test point B and my goal is to have it work with its own tuner I know you said I could take the other route with video inputs but I would rather find this headache and be done with it. After seeing the video flicker in and out clear there is another obvious problem something is more then likely leaking to ground I feel it don’t know why but I do. And an arc somewhere can only do what it did in an instant I don’t think it’s a tube. I had an rca don’t remember what chassis but I had a disc cap short dead to ground and took out the flyback and ho transistor so those caps do go bad. In this case I just don’t know.
