Magnavox 25CR12 C121. Thanks!

That model number does not compute for me, unless it is a
euro/asia model and I do not have access to that information.
Are you sure it isn't 25TR12?

If so, it could be an X6 chassis that may be subject to the
main B+ capacitor failure syndrome. 100uF 200V capacitor
goes open due to surge/thermal damage. Once open, the supply
loses regulation and climbs from its nominal 129V to something
more like 145V, which makes the horizontal output transistor
dissipate more heat. The HOT eventually shorts out, which
usually blows the 2.5A pico fuse, occaisionally damages other
stuff. The horizontal drive supply resistors also get hot
enough to burn off their printing and crystallize their solder
joints. I see these often enough to have it down to about a
half hour.

Other possibilities are B8 or P6 chassis which are switch mode,
run-all-the-time supplies that are much kinder to capacitors.
