Is your Vizio soundbar not connecting to TV? Are you missing out on some quality time with your friends and family? You’ve come to the right place as we’ve got the solution for this problem.

When any electronic device doesn’t function as it is supposed to, that can be a cause for concern and frustration. You might think that you invested poorly, but the reality is that electronic devices such as TVs, laptops, and even a home theatre system can malfunction, as nothing is 100% foolproof.

That said, we’ve put together a list of solutions that can help you get rid of this issue and get you back to enjoying a cinematic experience right from your bedroom. So, without further ado, let’s get right to it.

Methods to fix the Vizio soundbar not connecting to TV issue

Here are some fixes that you can try to quickly resolve the connection issues your Vizio soundbar might be running into.



Check for power

If your Vizio soundbar isn’t connecting to the TV, ensure it’s getting enough power to operate normally. 

  • Unplug the Vizio soundbar from the outlet.
  • Check the power cord for any signs of damage.
  • Plug it into a different power outlet and turn it on.
  • If it turns on, the cause was a faulty outlet not delivering enough power for the soundbar to turn on. 

If it still doesn’t turn on, move on to the next step, as the likely cause is something else.



Power cycle the Vizio soundbar

Power cycling can resolve most if not all, issues, especially if software glitches or bugs cause them. This process removes any power the circuitry holds and resets the device. Power cycling your Vizio soundbar might resolve the issue of not connecting to your TV.

Here is how you can do it:

  • Unplug your Vizio soundbar from the power outlet. 
  • Press and hold down the power button for 30 – 40 seconds. 
  • This should deplete any energy from the internal circuitry.
  • Leave it for 5 minutes. 
  • Plug it back into the power outlet and turn it on. 

If any software-related issues interfered with your Vizio soundbar not connecting to the TV, this should’ve resolved that.



Update that soundbar’s software

A likely cause for your Vizio soundbar not connecting to the TV might be that its software is outdated and needs an update. Outdated software or firmware can cause issues in performance, so updating it might resolve this issue. You can update your Vizio soundbar’s software via the Vizio SmartCast app or take the long route: update it via PC. 

Here is how you can update your Vizio soundbar’s software using the SmartCast app: 

  • Go to Google Play or Apple App Store and download the Vizio SmartCast app.
  • Open the app and set it up. 
  • Once set up, open the “Settings” and choose the “Check for Updates” option.
  • It should start searching for any available updates and prompt you when it finds any.
  • Select “Yes” to install the update and wait for it to finish.
  • This should update your Vizio soundbar’s software.


Updating the Vizio soundbar’s software via PC:

  • Open the SmartCast app and select your sound bar. 
  • After that, look for the gear icon and select it.
  • This should open a list, and select “System” from it. 
  • Select “System Information.” 
  • Select “Soundbar Information.”
  • This should display the firmware version.
  • Head over to the Vizio support webpage.
  • Search for your soundbar’s firmware version and download it.
  • Once the download is complete, connect a USB (around 2 GB) to your PC.
  • Extract the files directly into the USB and ensure no other data is in it and that it is FAT formatted.
  • Power on the sound bar and change its input to one with no audio.
  • Insert the USB in the USB port.
  • The lights should start flashing; this means that the firmware is being updated.
  • Wait for the lights to stop; this indicates that the process is complete and it is safe to remove the USB.
  • You can check to see if the process was successful by looking at the firmware version in the SmartCast app. 

After completing this process, your soundbar should be able to connect to the TV. If this doesn’t work, then give the next method a try.



Disconnect devices which may be causing interference

If your soundbar isn’t connecting to the TV even after its firmware update, something else is wrong. There is a possibility that some other device is interfering with your TV’s ability to recognize and connect to the soundbar. 

In this case, you need to disconnect any devices connected to your TV. One way to do this is through Consumer Electronics Control or CEC. 

  • Press the “Menu” button on your remote.
  • This will display a list of options.
  • From those options, select “System.”
  • Select “CEC.” 
  • Turn it on. 
  • Then select “Device Discovery.”

This should display all the devices that are connected to your TV. Disconnect all of them and attempt to connect your Vizio soundbar to your TV again.



Factory reset your Vizio soundbar

If all else fails, factory resetting your electronic devices generally eliminates most issues, that is, if they are software-related. Doing so removes all your settings and configurations, so you’ll have to set it up again from scratch. 

You can factory reset your Vizio soundbar, returning it to its out-of-box condition. Simply follow the steps below: 

  • Press and hold the volume and Bluetooth buttons together for 5 to 10 seconds.
  • If that doesn’t work, try holding the input and Bluetooth buttons down for the same amount of time. 
  • All LEDs should flash three times, indicating that the process is complete.



Contact Vizio support for help

If this issue persists even after a factory reset, then the issue is most likely with some internal component. In this case, contacting Vizio support is your best bet.

Why won’t my Vizio soundbar play the sound on my TV?

There could be several reasons your Vizio soundbar isn’t playing any sound. First, check if it’s getting enough power and if the power outlet is working. Second, check whether you’ve selected the correct input (HDMI ARC, Analog, Optical cable). Third, disconnect any external devices from your TV and try connecting your soundbar again. If your soundbar still doesn’t play any sound, contacting Vizio support is the final option.


If your Vizio soundbar isn’t connecting to your TV, that could be annoying as you probably wanted to have a good viewing experience of your favorite movies or TV shows. However, before panicking or thinking that you made a bad purchase – try the methods listed, and it might connect to your TV.

At times, electronics can malfunction due to a fault in the firmware or poor connection. These are easy to fix, as a quick power cycle or cable inspection will put things back on track. However, if the problem continues to persist, that could mean that there is something wrong with the internal components, and it needs to be changed or replaced. In this case, claiming the warranty and getting it repaired or replaced from the manufacturer is your best best.

That said, there are always more options available on the market, and if you’re interested in exploring some of them, check out our guide for the best Vizio TV for the best picks.
