Trinitron Horizontal Flicker

It comes and goes, so it's probably external.

Even though the source is external, I feel like the set being susceptible to these problems indicates a problem. Should I change the caps in the power circuit?

If you're not seeing any other indications of bad caps, you don't need to change them. It wouldn't help this.

If it is indeed external, and the problem isn't bad caps or anything else in the set, the solution is a voltage regulator like this?
