I wonder if you remember how you turned off the power.
Did you turn it off with the TV switch or did you turn it off with a switch at the variac?
The variac is a large coil, turning the power off to it can cause an inductive kick-back and produce a voltage spike. The voltage spike could cause something on the TV power input to short.

Trying to rejuvenate a color CRT is very iffy, there is a good possibility that it could make the CRT worse.

Color set can get out of adjustment and require a pattern generator to correct the convergence, etc.

When this set was produced a color TV was the most complicated electronic device in a home by a wide margin.
