Audio is missing from some speakers (not all) - Home Theater

The absence of audio coming from your sound system can be frustrating, but the steps below will help to find and resolve the issue.

Note: If the system does not power on, refer to Device Has No Power.

Note: If the system speakers play sound, but your wireless subwoofer does not, refer to Connecting Your Wireless Subwoofer.


Sound Test

Performing a sound test will play sound through each of your home theater system's speakers, and will not rely on an input signal. The test will determine if the problem originates with the speaker, a connection, or is specific to the system hardware.

Note: Please perform this sound test before moving on to the troubleshooting section.

  1. First, press the Home/Smart button on your remote.
  2. Choose Settings near the right side of the screen.
  3. Choose the Audiostop menu.
  4. Select Speaker Setup from this menu.
  5. Press the VOL + button on your remote until the volume level is greater than 10 (higher depending on hearing ability and ambient noise levels).
  6. Choose Test to perform a speaker test.
  7. Once the sound test is complete, please move on to the Troubleshooting section to diagnose the issue.

Note: While in this menu you can set the distance from your central seating position to each of the speakers. This will ensure proper configuration and sound levels.

  2. Is the sound missing from the wireless speakers only? Yes No

    • Press the Sound Effect button on your remote and choose any mode except for bypass. The other modes will play through all speakers even if the original program is not broadcast in 5.1 surround sound or greater.
