Is Your Vizio Sound Bar Not Working?

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.

Vizio sound bars pack a lot of audio punch into a very small package.


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 Turn On

If your sound bar 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.

Questions & Answers

Question: Why does the sound of my Vizio turn off when the channel is changed?

Scroll to Continue

Answer: Whether this happens when you change an over-the-air channel or cable channel, if the sound work sometimes and not others, I wouldn't consider that an issue with your soundbar, but rather with your TV or cable box. I would recommend trying to connect the soundbar to another TV to see if you run into the same issue. That will help you determine whether the problem is your soundbar, or if it's something else.

James on November 27, 2019:

Do not buy Vizio soundbars. Purchased from Sam's Club. From day 1 I get a high pitch screeching sound that requires me to unplug the soundbar to get it to stop. This happens every night after it has been on for an hour or so. Contacted Vizio Support, they were less than helpful. Save yourself the frustration and spend the money for a better soundbar.

Nischay Mishra on November 26, 2019:

It works fine but you have to get real close to soundbar inorder to control volume?

Vizio on May 14, 2019:

Problem: Soundbar will not turn off.

Solution: Using your remote, cycle through the menu to Reset. Select it and it will ask you to confirm. Do that and after the reset completes everything might be working.

Vizeo soundbar turns on after tv is turned off

Vkw on March 18, 2019:

I recently moved and am unable to get sound out of my Vizio sound bar. It was working ok before I moved. could it be because it was unplugged for so many hours and it needs to be reset. Has anyone had this problem. I have tried everything to get it to work. I also need a battery for my remote because that is not working either. But you shouldn't need the remote to make it work. Help

Coco on March 23, 2018:

I have a samsung smart tv and Vizio Sound Bar system. All worked great for over a yr until yesterday. For no reason I now can’t get TV sound on the Vizio speakers. When I play Spotify on my iPad via Bluetooth it will work. Netflix and chrome cast audio won’t work. I’ve tried everything. Reset Vizio, unplugged and plugged all connections. Checked audio setting on tv and it is PCM. Does anyone have any suggestions?

My sound bar sound goes out ( no sounds) whenever I play a game on my PS3. Any suggestions? I’m all ear

Max Dalton (author) from Greater St. Louis, Missouri on February 10, 2018:

If you can return it, then do that. If you start tinkering with it and break something on it, then you may be stuck with it.

Joan on February 09, 2018:

My Vizio SB3681 E6 periodically comes back on after I've turned it off. Mainly though, there is VERY soft sound from the rear speakers, and constant soft static. Sound from bar itself is fine. Had some written help from Vizio rep which hasn't worked. Do I have a lemon? I can return it because I bought it a week ago.

Miclidd on January 17, 2018:

My Visio sound bar will not turn OFF even with the power button on the sound bar. If I turn off my Samsung TV and turn it back on the Visio goes to max volume. I’ve unplugged it, reset it to factory still won’t turn off. Remote won’t turn it off either, the auto off doesn’t turn it off either. That flashing light searching for input on the Vizio is pissing me off when I turn off my TV. The volume works to turn it back down when I turn on my TV. Oh and it’s not my TV remote because I’ve even taken the battery’s out of all the remotes and have turned on the TV manually still max volume. It has also gone to max volume for no apperent reason as well. This thing sucks don’t buy!!

Felipe on January 08, 2018:

the vizio sound bar will not power off always lights move from side to side . I tried factory setting and nothing happened lights continue to do as always?

Rick on December 16, 2017:

Linda on December 02, 2017:

I accidentally touched something on the sound bar remote trying to turn down the volume and now we can't get it to work . Checked the mute on both the bar and tv remote and nothing works . Any thoughts?

Janet on November 05, 2017:

I got a Vizio 28 2:1 hooked up to a RCA tv. The sound is great but the problem is it will go in and out about every 2 or 3 minutes.

Walton cheramie on October 23, 2017:

My Visio sound bar after playing for 5 min which plays great,then all a sudden it starts making cracking noise to the right speaker went ahead change out speaker and still doing the same thing confused

Steve on October 22, 2017:

My Vizio sound bar is less than a year old. It has totally quit working. Have read all the comments and tried the different methods to try to restart it. Also followed the manual’s suggestions as well. No luck. Frustrating as it seems, this is just another poor quality product!

Samuel on October 22, 2017:

Don't buy Vizio sound bars. You can't get parts for them. I know I have tried. I had an RCA connector break on mine, I was able to pull the "daughter" board out that has the two RCA connectors on it. I got a part number from it. Vizio told me they don't sell parts, the three "partner" sites they give you don't sell the parts for sound bars. So if anything breaks - your screwed. I won't be buying another Vizio sound bar...

Max on October 17, 2017:

Unplugging the AC power cord on the back of my Vizio soundbar enabled the settings to be restored. All is back to normal. This was after spending 20 minutes on the phone with the Cox cable. They never offered the unplugging as a solution . Glad I found you.

Rodney on September 20, 2017:

Sound bar stopped working!!

Marcus on May 30, 2017:

I have the 4551 sound bar surround hooked up to a Vizio 65" sound bar works and sounds great, but lately it powers on by itself after shutting off the TV. I will power off the Tv/Sound bar with my cable remote, but 3-5 mins later the sound bar powers back on with cable audio and the tv remains off. Did a full reset and seemed to work, but I just came home to the audio playing again after shutting things off before leaving home. Any ideas?

Gordon on May 02, 2017:

Im playing music from my phone on my visio sound bar and the volume keeps going up and down by itself. Any ideas?

Bob on March 29, 2017:

I have tried everything and cannot get the sound bar to work. it has power. I used the digital optical cable hooked up from the back of my Sony TV. The connection is good. The soundbar is set to receive the digital optical cable (option 4). Nothing. Nothing is on mute. I tried to set the TV sound from "speakers" to "audio system" Nothing. I switched it back. nothing. Could there be a compatability problem between Sony TV and Visio sound bar?

Shawn Jones on March 19, 2017:

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?

Ron on March 16, 2017:

The sound from the sound bar went out and we have tried everything. Can't get it to work for hours now.

Mark Z on February 23, 2017:

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

Max Thacker t on February 21, 2017:

Vsb207bt vizio sound bar connected to toshiba 50 inch flatscreen with optical output wire

But I don't know what input is in. I push input button and one blue light come on then white light comes on starts going back on sound bar. But I can' get any sound.

Jordan on February 20, 2017:

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?

Carrie D on February 11, 2017:

My soundbar is making a clicking sound and everything I have tried doesn't clickclick

Deb M on February 05, 2017:

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!!

Moosch on February 02, 2017:

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.

Ryan -ll on January 31, 2017:

S4251w worked perfectly for 2-3 years, up until I plugged it into a different outlet, and now it is unresponsive to the power, input, and bluetooth buttons. Volume buttons are the only responsive ones, but the volume just resets to half way when let go, and can't even reach under 2 bars, which in my time with this bar, might mean the volume is currently controlling the input. (maybe not) Phones / tv / anything can connect to the soundbar, but it seems like the bluetooth button is stuck and is overriding the action of any other button. I have tried resetting it, it does "restart" but goes back to searching BT connection after few seconds.

Francisco on January 29, 2017:

Vizio Sound Bar SB4051-D-5.

When my 45" 5.1 Vizio is connected, the audio and video jump to the input screen for a few moments, then return. Using the HDMI cable dedicated to the sound bar on a 60" Vizio 4K TV.

Quincy Cunningham on January 11, 2017:

@ Sharlene Just "forget" the soundbar on your device's bluetooth menu. Then reconnect. It should work after that.

Yvette on January 09, 2017:

Thank you the information you provided was very helpful.

Sharlene on January 09, 2017:

My Vizio sound bar works for almost a year, but now it has really lower I almost cannot hear it when I paired with Bluetooth from my phone or tablet. Even I turn the sound bar and phone to highest sound.

Please helpe if anyone has same experience.


Max Dalton (author) from Greater St. Louis, Missouri on December 15, 2016:

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.

Paul E. on December 13, 2016:

Trying to get audio from model # SB2920D6 soundbar using the optical input. I have confirmed there is a signal (red optic) coming though the optical cable. I've tried this on several brands of TVs but still no sound unless I connect the analog input.

Why does the volume go up and down on the sound bar when commercials come on and every so often the bar cuts off for a second

D on November 05, 2016:

So my soundbar starts getting a buzzing noise. It get progressively worse and worse. An easy fix to it (for about 30 min) is to switch from one tv output to another and then back again. WTF?!

T Rhodes on October 27, 2016:

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.

Tommy on October 27, 2016:

Max Dalton (author) from Greater St. Louis, Missouri on September 13, 2016:

Try muting it using the physical button on the sound bar rather than the remote control.

Max Dalton (author) from Greater St. Louis, Missouri on September 13, 2016:

It's going to sound silly, but try moving them closer together.

Max Dalton (author) from Greater St. Louis, Missouri on September 13, 2016:

Try moving the two devices closer to each other.

Max Dalton (author) from Greater St. Louis, Missouri on September 13, 2016:

I would exchange it ASAP and see if they'll ship you a different one. Issue is likely tied to the fact that it's a refurb.
