Vizio Soundbar Lights Going Up and Down | Solution

Vizio Sound Bars are designed to provide a superior audio experience, improving your TV’s sound with dedicated power and volume controls. They use built-in speakers to give you a full range of sounds, from deep bass notes to high treble tones, for an immersive listening experience.

The lights on the Vizio sound bar occasionally begin to flash up and down. You might wonder if your sound bar has a hardware or software issue with your sound bar because it won’t work. Vizio sound bars have numerous controls that let you alter the settings to your liking. Sometimes these settings needed to be corrected or caused a problem with your sound bar. You might be experiencing issues like no sound if your Vizio sound bar flashes up and down.

All Vizio sound bars are susceptible to this issue, but if lights are flashing up and down, they won’t have the same problem.

What the Vizio Soundbar Lights Mean

The Vizio Soundbar’s LEDs display the equipment’s volume level. When you increase the sound, the indicator lights gradually move up until it reaches their maximum limit. Conversely, the indicator lights will decrease when you reduce the sound. The LED bar is a physical representation of how loud your sound is and can be used to adjust the sound level manually. Also, you may manage your Vizio Soundbar through a suitable app on your smartphone or the remote control that comes with it.

Causes of Lights Changing Directions

When your Vizio Soundbar’s indicator lights are going up and down, it usually means that the device is either receiving a signal or responding to changes in volume. The indicator lights might respond to the volume of what you are watching or listening to if you have connected your soundbar to a compatible audio source, like a TV. If you find the indicator lights going up and down uncontrollably, it may be a sign that your soundbar is not properly connected to the audio source.
