This could be a cold solder on the CRT socket assembly, bad connection
between the focus grid of the CRT back to the focus supply, or a defect in
the high voltage multiplier, and or the CRT may be failing.

If you are not experienced in TV servicing and equipped to do so, it is best
to give the set out for proper service. There are some serious safety issues
with working inside of TV sets.
