Why Is My Vizio Soundbar Flashing White? 5 Easy Fixes!

Last Updated Mar 20, 2022

The company Vizio, in recent years, has come to make much more than flat-screen televisions. They also make a very high-quality soundbar which comes as a surprise to some people. Once they are up and running, they offer some of the better sound quality you can buy at a price.

However, they are not without their issues. If your soundbar flashes white, chances are it is trying to cycle through all of your sound inputs, trying to find the proper one. These are the most common reasons for this issue and how to fix them.

There is five total, so keep reading to find out how!

Is the Soundbar Set to the Correct Input?

Every once in a while, the soundbar is simply set on the wrong input. The soundbar will then search for signals that simply are not there.

To check the input:

  1. Make sure that the TV is turned on with sound playing.
  2. Then, press and hold the input button on your soundbar until it begins to blink. Because you held in the input button, you essentially have forced the soundbar to go into a search mode that will cycle through all of the inputs available in hopes it will find the correct one.
  3. It should find the input your TV is plugged into, assuming the correct output is utilized.

One note to make, the flashing light from you pressing and holding the input button is different from the flashing when the bar is not working. Unless you trigger the search mode to start, the flashing is a sign of an error.

Is the Device Connected to the Audio Out On the TV?

Another reason you have a blinking light is what output (or input) the cable is plugged into. Modern televisions have so many inputs and outputs on the back of the TV, and if you are not careful, it would be simple to plug into the wrong one.

The proper outlet will be labeled ‘audio out’ and is the one and only option to make the bar work. Make sure the cable is securely plugged in. It might help to take the cable out and plug it back in just to make sure it’s fitting just right.

Have You Tried a Factory Reset on the Soundbar?

The first two options not working? The next step would be to try a factory reset. Vizio has a large number of soundbars available, so you will have to do some simple searching on your own to find instructions on your specific model.

In general, you simply have to press and hold both the ‘Bluetooth’ and ‘Volume Down’ buttons together for 5 seconds. This will trigger your soundbar to go all the way back to factory settings, where you have to treat the device as new again and reconnect everything.

Is There Power Connected?

Often, it is the simplest fix possible to get your device connected again. A properly connected soundbar should have one white light on once it is connected. It will be on the left-hand side of the device.

If you are not seeing any lights at all, ensure the power cord is connected to the bar and the power supply at the wall. The connection may be slightly loose. Also, check the outlet itself to make sure it has power.

You can also try unplugging the soundbar at this point and allow it to sit for at least five seconds before plugging it back in. This tried, and true method is useful on many electronic devices as a sort of soft reset and can sometimes make everything work again.

Final Thoughts

If you have tried all of these fixes and nothing worked, the final thing to try is to this method:

  1. First, reconnect your soundbar but to another device instead of your television.
  2. Then, restart the search mode that was previously talked about in this article to get the soundbar to detect the new input.
  3. Now, listen for any type of sound from the new device.

The point of this step is simply to find if there is trouble. If there is no sound at this point, there is probably an issue with the soundbar itself. If there is sound, the issue will be found with the first device it was connected to. In the event it was the soundbar, Vizio service can be contacted here and is quite helpful.
