I have ONN tv E021M425-J3 on the circuit board.

The TV buzzes when on. Nothing plugged in but power cord.  Cord plug confirmed in.

Buzzing happens when the unit is on and stop after turn off.

I think the cap 10uf 450V might be the issue. It is really hot about 200 degrees f and the top is swollen. The board is a little discolored near this cap.  The sound has become distracting.

The screen and sound works. Please advise
