Product will not turn on

If your product appears to be receiving power but won't power on as expected:

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.

Check the power connections at your product and at the power source.

Be sure the power connections to your product are secure both to the AC (mains) outlet and to your product. For more info, see Connecting to power.

Try both the buttons on the product and the buttons on the remote control.

Check if either the buttons on your product or the buttons on your remote can operate your product. If buttons work on one but not the other, see Remote is intermittent or does not control your Bose product or Buttons on product do not work or work intermittently.

See if the remote is sending IR signal by looking at the top edge of the remote through a camera viewfinder.

Our eyes cannot detect the IR (infrared) light produced by your remote but many digital cameras can. Look at the top edge of the remote through a digital camera (i.e. a smartphone camera), then press a button on the remote. If you do not see a flash through the camera viewfinder when a button is pressed, the remote is not sending any signal*. If you do see a flash but the remote is not working, try the other troubleshooting suggestions to help determine if the issue is the remote or something else.

*Some smartphones have IR filters on the front and/or rear cameras, which prevents them from seeing this flash. So, if you don't see a flash, try both the front and rear camera, a different camera if available, and any other troubleshooting suggestions.

Be sure the power cord is connected to a working power outlet.

If the outlet is controlled by a wall switch, be sure the switch is on. You can also verify if the outlet works by connecting another electronic device, such as a lamp. If connected to a power strip (or surge protector), try bypassing the power strip and plug the power cord directly to a wall outlet.

Check the condition of the cable that connects the system console and bass module.

Disconnect the cable that connects your system to the bass module. Be sure the connectors at both ends of the cable are not damaged and that the cable is not bent or broken. If there is damage to the cable, replace it.

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.
