I have a nice bright 1999 19-in WG CRT in a Revenge From Mars Pinball 2000 machine that emits a whine. Is this a loose flyback transformer or other cause, and what can be done easily to quiet it?

That is normally the flyback making all that noise. I have changes a flyback and the caps around the power section on a Hantarex monitor and the winning noise went away. I think it is normally just the flyback is bad.
