I would. It most likely needs nothing more than cleaning out all the
gunk.


It's been a long time since I fixed my CRT TVs. But, wasn't it that the
picture expanded when the HV briefly collapsed when arcing? I can't see
this happening in the video.

I would expect the image to shrink horizontally &/or lose brightness
during arcing.
