Why is there no sound from my Bose GS III 3.2.1 Home Theater System?

  Tiffany JohnsonAug 19, 2025
  If you're not getting any sound from your Bose Home Theater System, try these steps: First, increase the volume and check if MUTE is on; if so, unmute it using the remote. Ensure you've selected the correct source (CD•DVD, CBL•SAT, etc.) on the remote. Verify the audio connections for the component you're trying to play, and connect the FM and AM antennas. Make sure the cable connecting the Acoustimass module and the media center is securely attached, as well as the connections between the speakers and the Acoustimass module. As a last resort, turn off the media center for 60 seconds, then turn it back on to reset the connection with the speakers.

  If your Bose Home Theater System isn't turning on, ensure the Acoustimass module power cord is securely plugged into both the AC outlet and the module itself. Press a source button (CD•DVD, CBL•SAT, etc.) on the remote. Try unplugging the power cord for 60 seconds, then plug it back in to reset the unit. If you have a 230-240V system, verify the power switch on the Acoustimass module is turned on ( I ). For a dual voltage system, confirm the voltage setting is correct for your region.

  If your Bose Home Theater System is producing a loud hum or buzz, try plugging it into a different AC outlet. Check if the media center and its audio input cable are within 3 ft (1 m) of other electronic devices like TVs, cable boxes, routers, dimmer switches, or microwaves, and if so, move the media center farther away to see if the noise stops.

Why does my Bose Home Theater System have sound but no picture?

  briannaarmstrongAug 30, 2025
  If your Bose system has sound but no picture, ensure the TV is on and set to the correct Video Input for your Bose system. Also, make sure a DVD is in the disc tray. If connected via HDMI, try switching Video Inputs back and forth, or power cycle the devices in a specific order: first the TV, then the Bose system. As an alternative, disconnect and reconnect the HDMI cable or try using a Component, S-Video, or Composite cable instead.

  If your Bose remote isn't controlling your TV, CBL•SAT, or AUX component, make sure the remote is set to control that component. Ensure nothing is blocking the front of the component. Try resetting the remote using a different device code for the component you want to control.

  To troubleshoot a Bose Home Theater System radio that doesn't work or has poor reception: Ensure the antennas are connected. Adjust the FM antenna position to reduce interference. Move antennas away from the media center, TV, or other electronic equipment. Try selecting another station, as you may be in an area with weak signal coverage for some stations.

  If the picture on your Bose system is black and white, flickers, gets dark, or rolls, check the video cable connections.
