If your Vizio soundbar is flashing white lights, then you must follow the below 5 methods


First, check all of the connections to your soundbar. Make sure that the power cord is plugged in and that all of the audio cables are securely connected. If you’re using an optical cable, check to make sure that it is inserted all the way and is not loose.

If everything looks plugged incorrectly, try power cycling your soundbar. To do this, unplug the power cord from the outlet and then wait 30 seconds before plugging it back in. Once the soundbar powers back on, see if the issue has been resolved.

If you’re still seeing flashing white lights, try resetting your soundbar. To do this, press and hold the power button for 10 seconds. This will reset the unit and hopefully fix the problem.


Check if there is any audio playing on the source device. If not, then please turn on the music or any other audio-playing application on the source device. After that, check if the Vizio soundbar flashes white light or not.


There might be a problem with the audio settings of your Vizio soundbar. So, go to the sound bar’s menu and check if all the settings are correct or not. For instance, if you’re using an optical cable for connecting the soundbar with the TV, then check if the ‘Optical Mode’ is set to ‘Bitstream’.


If you have multiple devices connected to your Vizio soundbar, then try disconnecting all of them except for the one that you’re using as the audio source. Once you’ve done that, check if the flashing white lights issue has been resolved.


If none of the above methods work, then there might be a problem with your Vizio soundbar itself. In this case, we recommend taking it to a nearby authorized service center for further assistance.
