Try removing the cover & running it in a blacked out room to see arc.
Set has a focus divider, white block behind the cage. Those can
crack & arc.

I removed the top plastic cap to see the pins where the red and white wires go. First I hear the high pitched CRT whine seconds after powering it on. Then the arcing starts. The arcing is still happening and clearly is jumping between the red and wires across the pins they connect to. Also there appears to be a second spark happening right after the first bright one which is seen flying off bottom part of the metal chassis (near the HV metal box perhaps)
