Now that you have it open, you might try placing it carefully so that
it can be operated with the back off.

Listening carefully may reveal that the sound you hear is just a
result of mechanical play in a ferrite core of the flyback transformer
or the yoke.  If so, slight tightening of a clip or screw or application
of some Glyptol lacquer could solve the problem.

Wholesale re-capping is seldom necessary or useful.
