Why do my subs make a buzzing sound?

What causes a digital television to make a loud buzzing sound?

• My one year old Samsung digital television is making a very loud buzzing sound which is also interfering with the picture and sound of the programmes. This has never happened before. Is this more likely to be my television malfunctioning, or interference? Any advice appreciated. Thanks.

• Answer:

  Is it a Plasma or LCD, LED tv? I ask because Samsung plasma tv's have a known buzzing issue. I would try to isolate any interference issues first, make sure there are not any unshielded speakers next to it, make sure any audio shielded wires are in good shape. I had a person living down the street that talked on the radio and he would come thru the tv audio sometimes, but that was not a buzzing. good luck, I hope you get it figured out.
