Vizio soundbar white lights flashing might be a minor issue but we have to agree it’s annoying. You don’t need to wait for it to eventually stop.

Because we have gathered 4 simple ways to fix this issue.

To fix the Bluetooth connection make sure you have a device nearby to connect. Connecting or pairing the soundbar might stop the light from flashing. 

It didn’t stop? Bluetooth pairing sometimes does not work in the Vizio soundbar. Don’t panic! You will see the Bluetooth icon beside the volume ‘-’ icon. Just press the button for 6 seconds.

Hopefully, this will stop the soundbar from flashing white lights. We suggest you do this method again after turning the soundbar on and off.

Solution 2: Reset Audio Input  

Are you dealing with an audio input problem? The soundbar tries to find out the location of the input. While going through this action the soundbar flashes white lights. Vizio soundbar will try to warn you about the input by flashing.


The ‘input’ button should be on the top of your Vizio soundbar. Just beside the input button, you will find the volume up button.

All you need to do is press both of the buttons and hold up to 6 seconds. While you are doing this the soundbar will automatically be the default audio input. 

After the soundbar changed the audio input the flashing should stop. You can also change the external audio inputs. Replace those with better input cables.

Solution 3: Turning Off The Demo Mode

New users of the Vizio soundbar face this issue most of the time. The soundbar stays in the demo mode while it is displayed in the shop.

Demo mode does not let the user access all of the features and functionalities. Your Vizio soundbar is locked in this mode and shows the white light.

Find out the input button and the Bluetooth button on your soundbar. Press and hold both of the buttons at the same time.

Hold the button for 6 seconds. You should see the lights of your soundbar will blink five times. Blinking five times after this means the demo mode is turned off.

Observe the LED lights closely. If it did not blink five times you should repeat the process.

It didn’t work? Press the ‘input’ and the Bluetooth button for 5 to 10 seconds. If the Vizio soundbar is not still resetting, try the next one.

You can try pressing and holding the ‘input’ and the volume ‘+’ buttons. Hold these two for 6 seconds to perform a factory reset.
