Abnormally loud flyback- causes, fixes?

Updated to say that pressing with my finger on the certain parts of the ferrite core while it's turned on (I know, reckless!) definitely silences the squeal, so this is on the right track.

Yeah, I don't know if I'd replace it if it's functioning ok. I'd try a wedge. Maybe wooden, or maybe even a rubber wedge used for monitor yokes (if you cut it down into smaller pieces). You might get it to quieten down.

Yup, I was thinking that or I have some pieces of neoprene sheet I could cut up and use for jamming into crevices as necessary. Of course, all of this assumes I can figure out the issue I'm having with my RGB signals going into this thing. RGB modding is not doing well. This was a high-end consumer monitor, not an arcade monitor, and so it was not designed for 15khz analog RGB, but rather accepted both NTSC composite and TTL RGB. I've been getting closer to having it work, but it's having some issues still, and I'm pretty stumped after today.
