Good question. I checked and the coil is tight. After running the TV for several hours tonight, I felt the coil and it was barely above room temperature and the core was warm but not hot. I could grab it with my hand and hold it for a long time with no problem.
The squeal seems to have diminished some. Barely audible now. I'll check it in the morning and see what happens.
