Electrical interferences and improper connections are the major causes of humming noises on a Dynex LCD TV. Humming noises distort sound and cause unpleasant noise that makes enjoying your favorite entertainment difficult. If the sound quality of your Dynex TV has deteriorated, Dynex provides several solutions to get rid of humming sound problems and improve your TV's overall performance.
