Bose's 3-2-1 Series II DVD home entertainment systems were sold from 2004 to 2008. The systems were expandable and allowed for the connection of other equipment. They included a radio and remote control. Problems with the entertainment systems included discs not ejecting, a lack of sound, sound but no picture, the remote not working, and components like the radio or DVD not playing. These kinds of problems can be identified and corrected.

  1. 1

    Turn the Bose 3-2-1 II entertainment system off if the DVD won't eject when you press the "Eject" button. Then, unplug the Acoustimass unit from the outlet; the Acoustimass unit is the subwoofer. Press and hold "Eject" and then power the media center back on. The disc should eject.

  2. 2

    Increase the volume and check to see that "Mute" isn't selected if there is no sound. Check all the cables, in particular make sure the Acoustimass unit is plugged in. Check that the disc is label-side up, and that there is indeed a disc in the tray.

  3. 3

    Turn the television on if there's sound but no picture. If you're playing a DVD, check that the television is set to the right video input. Toggle the "Input" or similar button on the television's remote.

  4. 4

    Replace the batteries in the Bose's remote if the home entertainment system won't respond. Then point the Bose remote at the Bose 3-2-1, and the television's remote control at the television. Replace the batteries on the television remote if the television won't respond. Press the correct button on the Bose remote to activate the desired component. For example, if you want to hear the radio, select "FM" or "AM." To use the DVD player, choose "DVD."
