No audio from product

If your product seems to be set up properly but does not produce sound, try the following:

Be sure the system is set up properly and all connections are secure.

A connection may have come loose or may be connected incorrectly. For more info, see Setting up your product.

In the TV menu, look for applicable audio/sound settings.

Many TVs have a menu setting that allows audio to be sent to speakers other than the TV speakers. In the TV menu, navigate to sound settings and look for a TV Speakers or Audio Output option (or something similar). The TV speakers may need to be turned off and the output may need to be set to Fixed or External Speakers. (Tip: If there is no fixed output option, you might need to turn up the TV volume to max to hear it through your Bose speakers—even if the TV speakers are turned off.)

Check the volume level on the Bose system.

When the system is turned on, its volume slowly ramps from zero to the last level used. If the system was turned off at an extremely low volume, it ramps to a moderate volume level. Pressing the volume button during this process sets the volume and stops if from ramping. If a higher level is desired, increase the volume gradually.

Check that that the correct audio input source is selected.

If multiple audio sources are available or connected, be sure the correct source is selected. For example, if the audio device you want to hear is connected to the auxiliary input, be sure that input selected.

Check that that the correct audio source is selected.

Since there is more than one audio source built-in to your system (i.e. FM and AM radio), be sure the source you want to hear is selected on the system.

Reset your system

A reset is used to correct occasional product issues. It is not something that a product should require repeatedly. For more info, see Resetting your product.

If your bass module was replaced with another unit, determine if it has a dual-voltage switch.

A dual-voltage bass module will have a red switch near the power jack indicating whether it is set to operate on 115 or 230 Volts. If your bass module has a dual-voltage switch, be sure the correct voltage setting is shown. If you need to change the switch setting, unplug the bass module power cord, change the setting, then reconnect the power cord.

Check the condition of the speaker wires and be sure they are secure at both ends.

Check the speaker wires for any kinks, scratches, cuts or damage. Replace any damaged wires and check that they are securely connected at both ends.

Try another input on the Bose system.

The input may be defective; try another input (it is ok to use a different type of input, for example analog instead of digital or digital coax instead of digital optical). If the problem only occurs on one input, that input may be defective. Follow the link below for more information on how to service your product. Depending on your product and region, you will be provided a contact number or the ability to setup service online.

Connect the audio/video device to a different input on the amplifier or receiver

Plug in to a different input section on the back of the receiver using the same cable(s) to determine if the input is the issue. Whichever section you connect to, select the same input using the receiver or remote control buttons to hear and/or see the device.

Your product may need service.

If the steps provided do not resolve your issue, your product may need service. Follow the link for more information on how to service your product. Depending on your product and region, you will be provided a contact number or the ability to setup service online.
