Well, while replacing R804 today it turns out the in-circuit resistance reading was incorrect. It was always 12kΩ even with the paint bands falling off!! I replaced C1603 and C1604 but there's no difference in behavior. I have replacements for all the small value bipolar caps but something tells me that won't fix the H sync either.

The H lock fails began post-recap, picture was fine before it. First thing I did after the recap was run with a 100W or 200W lightbulb in the +B circuit. I removed the bulb when strange behavior occurred (no picture, audio still running). So either the lightbulb caused damage, or something is different after the recap.
Not to mention the other complications that appeared when reflowing solder joints for the PSU, H circuit and chroma zone.
