Question about Televison & Video
This is a Switchmode transformer, a Choke, "Buzzing" this is happening because something is "Ringing" and causing the windings to vibrate and thus produce an audible signal, this usually happens prior to a unit faulting and is caused by too much current, or the incorrect oscillation frequency, overloading it, and it makes a noise due to it. You need to get this attended to, as it may, fail, and cause a fire or an explosion, or both.
