Troubleshooting Vizio Sound Bar Problems

Max holds a B.S. in Mass Communications from SIU and an M.A. 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 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?

        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.

        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.

        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!!

        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!

        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...

        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.

        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?

        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?

        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.

        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?

        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.

        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.

        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.

        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.

        I need cables 3 years ago

        I am missing all the cables on my sound bar. Model # CSS2123B/F7 also I have no instructions, no registration card. The large Box speaker has a cord to it, but I don't have any other cords. I also have the remote. Where can I get the rest of the the cords ?

        Thank you so much. How would anyone know that the sound bar won't have audio on HD channels unless you switch to PCM audio output if youre using an optical cable. Thanks again.
