1980 Sears (Sanyo) 25" Console TV CRT Problem

This is becoming quite an adventure here....

The problem now is not the power relay. Everything tests fine and put it back in.

Now the digital control board isn't working. Press power, and no voltage (12VDC) is on the coil of the relay.

There is a power regulator there that may be the culprit. Didn't have time to troubleshoot any further.

But recall how I said the TV randomly turned itself on when I plugged it in while I had the neck board off? It did that more than once, and only happens when you first plug the TV in. When it does that, the sound comes on, then slowly fades out, and I have no control. I had to turn the TV off, then back on. One time it did that it randomly started advancing channels on its own. It could have been that voltage regulator failing and putting out the wrong voltage causing erratic behavior.

The microprocessor is a long socketed IC. I think I should look up the datasheets on that and see where the input voltage is fed, and see if that is wrong.

And to make things even more complicated, not only do I not have the model #, I cannot even locate a chassis number. Just part numbers all over everything that doesn't help. I know I need to get a Sams Photofact so I can check other voltages at this point.

It could be multiple things, and I am not going to be able to get back into this set till next weekend.
