How to Troubleshoot your VIZIO Sound Bar. This feature is not available right now. Please try again later.
Using a wireless subwoofer with your sound bar limits the amount of unsightly cords dangling around your viewing room and creating a tripping hazard. Additionally, without the restrictions of a cable, you have more freedom over where you put the subwoofer in the room. Vizio sells wireless subwoofers with some of its sound bars, and makes pairing the two devices as easy as holding two buttons down.
Step 1
Plug the AC power cable that powers the wireless subwoofer into an available AC output. Plug the connector on the opposite end of the power cable into the 12-V power input on the back of the subwoofer. The subwoofer automatically turns on when you plug it in.
Step 2
Press the 'Power' button to turn your Vizio sound bar on, if it isn't on already.
Step 3
Position the subwoofer and the Vizio sound bar so that they are as close as possible, preferably no more than 8 feet apart.
Hold down both the metal 'Link' button on the back side of the subwoofer and the 'Input' button on the sound bar at the same time. The LED display on the front of the Vizio sound bar starts flashing rapidly, indicating that the two devices are trying to find each other; the two devices are successfully paired after the LED display stops flashing. If the devices still aren't paired after 30 seconds and the LED display stops flashing, try pairing them again.

Vizio soundbars are a great way to amplify audio from external devices without having to get an entire speaker system. This also makes soundbars ideal for pairing with devices for use in a small business setting. Most issues with Vizio soundbars stem from the device they're connected to or are the result of interference from another nearby device or object, but occasionally, the issue can be with the device's hardware. Use troubleshooting to try to fix or reset a Vizio soundbar before reaching out to Vizio support.
Tip
Don't forget to refer to your Vizio soundbar manual for troubleshooting information specific to your device.
Soundbar Won't Turn On
Check the Connections
Push the connectors on the power cord connecting the Vizio Soundbar to the external device firmly into the AC outlet it's connected to and also to the connecting port on the device. If the device is loosely connected at either end, it may not power on.
Try Another Device
Connect another device that you know works to the AC outlet the soundbar is connected to. If that device also doesn't work, you likely have an issue with the outlet, such as a blown circuit breaker or a defective outlet.
Remove Signal Blockages
Move closer to the Vizio soundbar and also remove any objects between the remote control and the soundbar, then try using the remote to power the soundbar on. The remote may not power the soundbar on if it's more than 15 feet away from the device or if there are objects in between the remote and the soundbar. If neither of those options work, try pressing the 'Power' button on the soundbar. If the device turns on, try replacing the batteries in the remote, as they're likely drained.
Tip
Make sure your Vizio sound bar remote has fresh batteries.
No Audio
Check the Volume
Turn the volume up on the Vizio soundbar and also ensure the soundbar isn't muted.
Check the Audio Settings
Check the audio settings on your external device and make sure it's set up to output audio through a connected device. For example, even if the Vizio soundbar is connected properly, if the TV is set up to output through the internal speakers only, no audio will be sent to the soundbar.
Check the Input
Press 'Input' on the soundbar's remote control or on the soundbar itself to switch what input audio is being played. Continue pressing 'Input' until the input for the external device you want to hear audio from appears on the soundbar screen.
Static or Buzzing Sound

Check the Cables
Check that the audio cables connecting the two devices are securely pushed into place.
Try a Different Input
Connect the connecting cable to a different input on the soundbar. If there's still a static sound, replace the cable, as it may be damaged or defective. Alternatively, if switching the input resolves your problem, the input you were previously connected to on the soundbar may be defective. In this case, contact Vizio support about getting the input fixed.
Remove Any Interfering Devices
Move devices that send a wireless signal away from the Vizio soundbar, as they can cause this type of interference. Devices that commonly cause interference include baby monitors, wireless routers and cell phones.
