@lukito@gamedev.lgbt so it's been over 30 years since I stopped repairing them...

But back in the day buzzing noises generally were due to the lacquer/glue breaking down allowing ferrite cores in inductors to oscillate.

The fix for that used to be a spray lacquer for high voltage parts.

If you're considering a diy repair be very careful.
