A color TV is like doing 3-7 radios at once with each set interlinked and feeding off each other's work.
Recap and tube checking alone will get many radios and some TVs going. But just as there are dog radios that need tough trouble shooting after the recap to work most TVs have need for troubleshooting as well as adjustments.
Don't mess with RF/IF alignment in TVs...That requires specialized equipment, and even with such equip is very difficult.
Tube based color TVs when used as much as they would have been when new, are not "fix and forget", but rather fix, and in .5-1.5 year fix again, rinse and repeat....These era sets are complicated and drive some parts HARD things wear out from use.
