I traced most of the capacitors that I replaced in that area and couldn't find one I missed, or misplaced. I'll try to get to the rest of them today. Is there another method to use with the horizontal afc besides turn it until you get a picture?

First off, don't be too concerned with the voltage readings on pins 1 and 3. They are at very high impedance, and your meter puts lighter loading on the circuit than the original meter did. Thus you get higher readings than the original meter gave.
In your last vid, it sure looks like the fine tuning adjustment is off. That's the outer shaft concentric to the channel selector shaft. Have you tried turning that stop-to-stop? Once the signal is tuned in properly, it'll be a lot easier to see what's going on with the horizontal.

What channel are you using to feed the signal to the set? Just on the chance that the tuner's tracking might be off, try clicking one channel higher and one channel lower, and fine tune stop-to-stop, and see if you can see a recognizable pattern (even with the horiz. frequency still off).
