Can we assume you were not trying to operate the tv set when it
supposedly failed?
The tv would had to have been turned on for a vertical circuit failure
as the voltages to it would normally be off when the tv is off.

Assuming that the vertical deflection is the only failure in the set,
it is way too far removed from the power supply to have failed from a
brown out.

Ac line - Main tv power supply regulator - Deflection/HV circuit -
Flyback derived secodary voltages - vertical circuit.

I've seen one model (forgot which) a year or so ago, that took the
vertical voltage from the power supply instead of the flyback.
