Hey everyone! My CRT is working, but it’s making a really unpleasant high-pitched whining noise. It’s honestly so annoying that I can’t even sit next to it for more than 10 minutes while it’s running. Does anyone happen to know what could be causing this?

A few years ago someone told me it might be the flyback transformer. Today I finally got around to opening the monitor up and discharging the tube. The solder joints around the transformer actually seem fine though.

Any ideas would be appreciated!
