Access is only from above. The screw is in a recess, and close to

How about a diamond tipped screwdriver blade? Apply a lot of pressure and
who knows, you might get lucky.

find time to complete the task and start fault-finding.

The capacitor on the one I repaired was a charred lump. I can dig up the
