Huh uh, no no...See what others has explained and one thing they
didn't bother to say that I'm adding to this. More on this below.


The voltages that run a picture tube is typically at the kilovolt range. On
average, a tube requires around 25,000 to 30,000 volts to power it, and that
voltage is generated by the flyback transformer.
Remember, electrical transformers can be made to step up or step down
electrical voltage. Flyback transformers are designed to upstep power up to
several thousand volts to properly drive a cathode ray picture tube.

Anyways, with that much voltage is a lot of potential for arcing to the nearest
ground, so proper and effective insulation for the anode cap, flyback line, and
flyback casing is essential. If the insulation is faulty or substandard, then
you will have an arc problem during operation. The final arc-snap that's
mentioned happens when the final arc uses the air as a bridge to ground through
the insulation towards a critical part on any of the circuit boards, destroying
it and causing more damage to the TV, possibly disabling it completely and
creating a new problem in the process.

If you've wondered why the inside of a picture tube must be a perfect vaccum,
this is why. Any air that's inside the picture tube will act as a bridge for
high voltage electricity and will make the anode feed arc to the nearest ground
inside the picture tube instead of properly powering it.

This kind of problem really requires proper servicing to correct it reliably
and safely.
The set should not be used ever again until the problem is corrected. -

Right.

The thing they didn't tell you over time with arcing and hissing, etc.
The arc is very hot temps (this reason arcs looks bluish molecules it
get excited are is very HOT to glow blue) and will carbonize the paths
arc takes and will finally stay this way (snap snap snap! Pow! POP! TV
dies.) and may take a part out or overload the flyback and kill it or
burn out the HOT. Seen this happen *many* times. Often the final
kill happened so fast that you hardly blink and utter "huh?".

Get it fixed while it's good! :-)
