JDW, it's a horizontal line, not vertical.
retrofreak83, I would look at possibly the second solution to your symptom on the SE/30 Repair Mac site; and that would be the Vertical Sweep IC at U2 (TDA1170A, 12-pin). If you would like a replacement, I've got one. I encountered the same problem on my SE-turned-SE/30's analog board. I tried replacing that IC, but the problem still existed. Eventually, I just replaced the analog board and all was good. But anyway, it is a good used part if you'd like to try replacing your original part. Send me a PM (private message) if you're interested.
I doubt the caps are the problem. The only thing to double-check is that all the caps were installed with the brown line side at the positive pad for each capacitor location (C1, C3 through C10, C12 and C13). Or even redo the soldering at each cap to rule out any bridging or shorts.
