The following conditions can cause your TV's speakers to buzz, crackle, or hum:

• Incorrectly or loosely connected cables
• Defective or broken cables
• A defective device connected to the TV.  For example, a defective DVD player.
• A problem with the TV itself

A procedure for determining the cause of buzzing, crackling, or humming speakers is below.

To Find the Cause of Buzzing, Crackling, or Humming Speakers

To find the cause of buzzing, crackling, or humming speakers on your TV, follow these steps:

1. Make sure all cables are connected to the proper, color coded inputs on your TV and on your devices, and that all cables are firmly attached. For instructions on making proper connections, click here. If you are using the Component connections, or RF coaxial cable from an antenna or cable connection, check the additional cable troubleshooting steps below:
• Component input. There is a red Component audio connection and a red Component video connection. Make sure the two red connections are attached to the correct audio and video outputs and inputs.
• RF Coaxial from an antenna or cable (no box). Turn on your TV and change to another channel. If the buzzing stops, your TV is not the cause of the problem.

If you still hear buzzing, crackling, or humming when you turn on the TV, continue to Step 2 by clicking on "Step Two" below.
