like that are from some Osc, you can see they are perfect repeating not waving

Is it always there? Does not look like a bad damper. If you got good Boost V.
Damper is most likely good. But with respect to the bars, On the outside, could
possibly be Heater-Cathode leakage, or short? Just a guess.....
Unfortunately, this might be a job for Mr. Oscilloscope.....
Some frequency getting into video? Does it remain or change
with Brightness, or Contrast change...?

there has been 10-15% width lost.
which is strange
is the horz frequency way off? or the Damper damaged?
