Bose's line of surround sound systems bring all of the acoustic, room-filling quality needed to create a powerful home theater experience. With features such as intelligent-playback mode and automatic audio calibration, Bose surround sound units are designed with usability in mind. But like any other surround sound unit, Bose's surround sound systems may need a little troubleshooting to address installation and performance issues.
Remedy power issues with your Bose system by rechecking the power connections. Ensure that the Bose's power cable is securely connected between the Bose unit and the power supply and that the power supply is plugged into a working power outlet. If your unit incorporates the VS-2 video enhancer, try removing the power cable from the VS-2 for about a minute. Reconnect the VS-2's power cable and try powering on your Bose system.

Ensure that you have an input source selected if you have power but get no audio or video output. Press the button corresponding to the desired input source on your Bose remote control.
Remedy sound distortion issues by turning down the audio/video source's volume. The signal sent from an audio/video source set at a high volume gets amplified when it passes through your Bose receiver, creating an overload on your speaker's circuitry and causing static. Turn the volume on the audio/video source to about 40 percent.
Eliminate sources of electronic interference to get rid of humming sounds present in your speakers' output. The humming sound you hear is likely caused by a nearby electronic device interfering with the Bose system. Unplug each electronic device nearby, one by one, until the humming stops. That way you know which device is the offender.
Turn down the volume on your Bose surround system if you experience an abrupt sound decibel drop. Your Bose system is designed to automatically lower its volume if it is overloaded. Turning down the volume decreases the power strain on your Bose system and allows it to return to normal sound levels.
