"Repeats horizontally" suggests the horz sweep is 'waay off frequency. I wouldn't use a pattern generator, but rather a regular signal source to get it on frequency first. Then see what the actual video looks like. You can tell a lot more that way.
You indicate absence of any waveforms at the sync sep. Sync is picked off the video chain right after the video output. Check peaking coils L7 and L9, and coil L8 for continuity for starters. And check plate voltage on the video output (pin 9).
