Yeah,  but why flyback?  Your use of the word "buzz" suggests a
lower pitch,  perhaps at the vertical rate or some harmonic of it.  Is
there something in there that's actually vibrating to make it buzz?

I'd say that they have to be a pretty exact match.

Workable if the boards are the same,  but I don't see anything in your post
that suggests that a flyback needs to be changed out.
