Because the pulses are spaced properly and the waveform matches the service manual perfectly.

Anyway if it's happening on both sides of the screen then
it's also happening during the damper scan too. To me that points to H-Pulse
or harmonics on Power Supply lines.....

I think it's obviously the H-Pulse ringing that's getting through somehow, but I don't see it on the power supply lines because they all the waveforms look "correct" as per the manual, and they make sense in that the pulses from the flyback are spaced properly. The electrolytics for the power supply filter caps have all been replaced with new, high quality Nichicon caps
