Well, I think I MIGHT have solved the video problem; but, the vertical circuit decided to take a dump before I could find out!
I found C126, a 100uf16V cap in the B+ line to the video stages to be reading only about 5 uf. I replaced that cap, turned it on, and I could smell a resistor heating up. A glance at the screen showed the raster to be shrunk and folded over. Then, the whole thing went to a horizontal line. The vertical IC (IC301 - AN5515) is bad along with the 220 uf pump up cap (C322) and the fusible resistor (R327 - 5.6 ohm). I'll replace these parts and maybe it will be fixed. If not, it's going to the curb.
