If disconnecting the yoke increases boost, that usually indicates a bad yoke.

With the TV on, remove the damper and check for voltage on the damper cathode. If there is any, look for a bad cap from boost to B+. If none, I would suspect the yoke.

If the yoke OEM code is 274, it's bad. If not, verify before buying a replacement.
