Troubleshooting Vizio Sound Bar Problems

Updated on May 03, 2016

Max holds a BS in Mass Communications from SIU, an MA in Communication from U of I, and is pursuing an MBA from Webster University.

A Vizio Sound Bar can complement an existing surround sound system or replicate one. This article will cover the following:

  • Static
  • Power problems
  • Audio problems
  • Resetting factory settings

These issues can often be fixed with a little effort on your part without having to exchange the device or return it to the manufacturer for repairs.

Vizio Sound Bars pack a lot of audio punch into a very small package.

Static

If your Sound Bar is producing a static sound, check the following:

  • The connectors on the audio cables you're using must be firmly pushed into both the Vizio sound bar and also the source of the audio. If the connectors aren't pushed all the way in, you'll likely experience some form of unwanted noise coming through the speaker.
  • The audio cables you're using to connect the sound bar to the audio source may be damaged in some way. Replace the cables you're using with different cables to see if that resolves your problem.
  • Use a different audio input into the Vizio Sound Bar. If the audio plays fine while the cables are connected, the issue is likely with the previous input you were using on the speaker.

Won't Power On

If it won't turn on, here are a few things you can try to get it working again:

  • If you recently experienced a major power surge in your home (such as a lightning strike), or if you have a large number of devices connected to an AC outlet that shares a circuit breaker with a large number of other devices, try resetting that circuit breaker in case it was tripped.
  • Check the power cable for cuts or other forms of physical damage. Sometimes people roll over power cables with chairs, step on them, or rest a desk on them accidentally, all of which can physically harm the cable. If the cable is damaged, you'll need to replace it using any standard 24-volt power cable.
  • If you're using the remote that came with the Vizio sound bar, try moving closer to the device and ensuring that there are no objects between you and the front of the Sound Bar. Also, position yourself within 15 feet. Outside of the 15-foot range, Vizio doesn't promise the remote control will work. Finally, try pressing the "Power" button that’s physically located on the Sound Bar. If the Sound Bar responds, you have an issue with the remote control. However, if it doesn't respond, consider contacting Vizio about your power issue, as it may be the result of damaged or defective internal components.

Audio Problems

If the audio is silent or you're experiencing other audio issues, try the following:

  • Make sure the source audio isn't muted on the source device.
  • If you can't hear any audio through the sound bar for a source that's connected via an optical cable, make sure the source device is outputting PCM audio. Some other audio types won't play through the Sound Bar when they're connected via an optical cable.
  • Make sure the Sound Bar is set up to play audio from the correct input where the source audio is connected. To ensure this isn't the problem, scroll through all of the Sound Bar's inputs.

How to Reset Factory Settings

For other problems you can't seem to solve using other methods, try resetting the Sound Bar to its original factory settings by doing the following:

  1. Turn off.
  2. Disconnect the AC power for roughly ten seconds.
  3. Reconnect the power cable. The settings on the Sound Bar will be cleared and the device will be restored to its factory settings. While there likely won't be any changes you notice, minor problems can often be resolved by doing this.

      I have an A/V cable connection from my Vizio sound stand to a Samsung 55" smart TV. The problem is, even though I set the audio output on the TV to A/V, TV speakers off, & PCM however the soundstand doesn't output anything​. I tried cycling through all it's inputs, I tried restarting both devices, etc. Nothing, no sound.

      Any suggestions?

      Sharlene, same thing happened to me. Vizio tech support told me to disconnect power cord from outlet and sound bar. Hold on/off switch on sound bar for 30 seconds. Plug back in. Disconnect and reconnect on your device. Worked like a charm for me

      My Vizio Sound Bar has to be unplugged and plugged back in every time I want to use it, then it works great until I power off my system and I have to unplug and plug it in again. (unplugging directly to sound bar not from wall)

      I know it sounds like a simple solution would be don't turn it off, but when I turn off my xbox all devices connected turn off as well. I can turn that off but I'd rather not and I'd like to not always leave the sound bar on. Any thoughts? Is this a power supply issue?

      I turn off my tv and then try to turn off the Visio sound bar, and it won't turn off either by remote or on sound bar button. Was on a chat with a rep for an hour and a half. Very frustrated with this product!!

      As I see that you keep up to date with posts I figured I'd comment and see if you know how to resolve my issue. Sunday 1/29/2017 we got a vizio sound bar with two surround speakers and a slim style subwoofer. It is 2/2/2017 and we are already having an issue. Every morning the bar essentially has to be 'reset'. When the TV is turned on for the first time of the day it shows a 'retrieving signal' screen. The one you'd see if nothing was connected. The sound bar is on, connections are proper, but it will not show picture or audio, as if nothibg was connected at all. I found that the way to fix this is to turn the whole system off at the subwoofer and then it should work. My problem with this is that my mother is not technology savvy and doesnt understand how it all works, she just wants to know that when she turns the tv on, she'll be able to watch it and if this happens to be first thing n the morning she cant use the TV at all. This has happened every morning since we got the system. Is this a common issue among soundbars? Is this 'the norm' and to be expected daily? Do I have a faulty system? Thanks.

      Go into the audio settings on the TV and ensure that it's set up to output audio through the optical output. I'd bet that's what's causing your problem.

      This happened to me. I fixed the problem by cycling through the inputs by pushing the INPUT button on the sound bar remote. It was not using the optical cable input (source 4). Hope that helps. It's nice to have my sound bar back.

      I have a Vizio SB4021E sound bar and woofer. The wireless woofer has never worked. Bar is great. I can barely hear a faint bass sound from the woofer. Is it possible the wireless frequency is not the same on the 2 units. This was a Vizio refurbished unit.

      May be a power issue. Do you have it plugged into a power outlet with a bunch of other stuff? If so, try disconnecting the power strip and plugging the sound bar directly into the power outlet and playing audio through it to see if that resolves it.
