Is it just the horizontal that is unstable? If so shotgun the resistors and mica caps in the horizontal oscillator, Horiz. AFC and any feedback from the fly. If not do the same for the sync section.
It may be a good idea to adjust the AGC (if present first).
If you rather troubleshoot than shotgun, I recommend getting a can of freeze spray letting it warm up and stabilize then start spraying things with it running. The part that makes it flake out when you cool it is the problem.
