Not entirely sure what to look for, however, here's the output of the plate on the sync. Hopefully that helps.

I've also purchased a TV analyst for troubleshooting, seems like a useful tool. WOn't be here for another week

Does this screenshot of the manual help? I had the same problem with my set and discovered that I replaced the cap that parallels the primary side of that transformer with a higher value and it filtered out the horizontal sync pulse to almost nothing.
