Okay, after fiddling around with the horiz. sync on the television, it just mustn't be syncing on the Horizontal. The best I can do is get it to "lock" on a multiple of 8 repeated horizontal images of the B&K test pattern. Flipping the B&K's polarity switch makes the image go negative.
I've checked every single component in the horizontal output circuit, and I guess I'll start working my way back to the sync clipper, etc. Tomorrow night.
With the video if circuits working away, could that possible swamp the B&K's signal, considering the contrast control is a really a B+ gain control for the IF strip?
