Could it still be the IC? I haven't done a cap kit yet, I plan on it tonight when I get home from work, but I have a feeling that the caps are not the problem.
You should try replacing C51 or just to a cap kit altogether. It will probably be the best $10 spent.Any one of the vertical trimpots on the main board of the 7195 could have a crack in it that could cause "no vertical deflection" symptom. If capacitor C51 is bad that would do it too.
Most likely though is the vertical output IC bolted to that heat sink is bad. Replace like numbered part with like numbered part.

Some of the newer IC's are a bit smaller than the older ones. You would need to drill a hole in the heat sink so you can bolt down the smaller IC. As long as the part number is the same it should be the right replacement part.
OK, a little update on this. I replaced the IC in IC3. I ordered the one that is listed in the manual, UPC1378. Got it, took out the old one, soldered in the new one. Still same problem. BUT...I think it was the wrong IC. The old one was numbered 7831 (I think), and was wider. The new one, although the same number of leads, is not wide enough to be screwed to the heat sink. Again, all I'm getting is a line across the screen. As before, there is movement within the line, and adjusting pots (ie. brightness) does have an effect on it, so somethings working.

Any input would be greatly appreciated, I'm too green at this too really have a grasp on whats going on. Thanks guys.
