I'd say your tv needs, as a start, a total re-building. Replace all paper caps, All electorlytics, make sure all resistors are with-in 20% range, and replace any that don't. Check for shorts in b+ supply. Some chassi mounted b+ resistors tend to short to chassis, and should be totally replaced. When you get that going, go from there. It may still need more if it still doesn't work.
