Vizio TV No Sound – Causes
- Out-dated Software – One of the primary reasons is that the TV’s software needs to be updated more to support the audio System.
- Loose Cable Connectivity – The Second is the loose cable connections that contribute to the power flow imbalance and, ultimately, your Vizio TV’s functioning.
- Improper Audio Settings – One elementary, yet another factor that leads to the TV’s dysfunctioning and ultimately contributes to its audio problems.
- Improper Remote Settings – Like the audio, even the remote control’s wrong settings might lead to a problem with the TV’s audio.
- Not Power Cycling – The power cycle refreshes your TV and gives it a smooth start. Not doing so at regular intervals may also contribute to the TV’s audio issue.

Vizio TV No Sound – Solutions
Unplugging the TV from the Wall
A quick and straightforward solution is unplugging and replugging the Vizio TV. There may be improper power flow, a problem with the socket or cable connections, or simply a loading issue which will be solved via this.
If it does not, move forward to the next available solution.
Update Vizio TV Software
Sometimes, this glitch in the audio might also be caused due to outdated software. This might cease occasionally operating because of software. Hence, in this case, you need to get your Vizio TV’s software updated.
Usually, if connected to the internet, this Vizio TV will automatically look for the available updates and get it done. Sometimes, the auto-updater is interrupted, so it must be done manually. Here are the steps for the same:
- Choose System from the drop-down menu after pressing the ‘V’ key on the remote control.
- Now check for Updates and if any are available.
- If yes, go for installing the same.
- The Vizio TV will now take its time and load the details after the update.
This should solve your issue. However, if not, try the other solutions mentioned.
Warranty Check for your Vizio TV
This is primarily a last-option thing, but if you need help figuring out the problem, you can see if your TV is still under the stipulated period for warranty.
After you describe the problem, the Vizio Support System verifies if the warranty covers it or not. If you have luck, it may, or else it may not.
In case it does not, look for the following options mentioned.
Ensure the TV is Not Muted
You heard that right; check if the Vizio TV is muted.
Everyone would have already tried this before reaching this article, but it is still worth mentioning before referring to the following solutions.
You are lucky if this solves your issue! If you need help, let us go ahead.
Keeping a Check on the Remote Control
The remote controls for Vizio TVs might become problematic after a certain point due to issues like dead batteries and improper settings.
Hence, considering your remote control while troubleshooting is a good idea and may help.
Try muting and unmuting the TV. If the remote is not operational, replace the batteries. Second, try pressing the volume button several times to make sure the volume is high, and it is a genuine problem. The mute symbol on the TV will guarantee the remote’s working.
If none of this works, however, it is time for you to replace your remote control. If the issue persists after replacing the remote control works, check out the next solution.
Examining the HDMI Cable
The transmission of both, the audio and video signals is greatly aided by the HDMI Cable your Vizio TV is attached to. This is situated at the back of your Vizio TV. A fault in this cable will, of course, reflect in the form of audio issues.
However, even this issue can be further segregated into three types mentioned below:
Loose HDMI Connection
Ensure your HDMI Cable connections are strong enough! Consider looking into it if you need help with more than one device. Or, you might follow these steps further:
- Unplug your HDMI cable from the Vizio TV and the device.
- Do this for all the devices connected to your TV through the HDMI.
- Replug the device and then check your connection.
Hopefully, this simple trick solves your issue! Let us look further if it still needs to.
Faulty HDMI Port
Connect to a different HDMI port if the connection is secure enough and you are on the correct input. Multiple ports are available in a Vizio TV; check if connecting to a different port solves the issue.
- Plug the HDMI cable connected to the TV.
- Now plug it into a different HDMI port. Note down the HDMI port number.
- Switch the input channel using your remote.
Remember to change the input to the port you switched to to test the new connection.
Bad HDMI Cable
If none of the above two works, consider fixing the issue by replacing the HDM cable you are currently using.
The condition of the HDMI cable also depends on its usage and the time it has worked. Moreover, if it is comparatively new, but you have moved it quite a few times, it might need to be fixed.
Ensure the Vizio TV’s Volume
If you have tried all the solutions mentioned above and can still not resolve the issue, check the volume of the Vizio Smart TV first.
If the Vizio TV is not muted, but you still can not hear anything, the volume of the TV by accident might be adjusted to zero. For this, press the ‘+’ button with the help of your remote control and ensure the TV’s volume is at least higher than zero for you to hear it.
Also, check the Audio Settings of the Vizio Smart TV.
- Factory Reset your Vizio Smart TV
You may have accidentally turned on or off something in the Settings menu of the Vizio TV, which has resulted in an issue with its audio output. If you can’t pinpoint the exact changes, you can return to default settings by factory resetting the TV.
Note: The only drawback is that all your settings, customizations, and configurations might also be removed. You must set up your TV afresh, just like a new piece, from language settings to connecting to your network again.
This will also change all your audio or video settings to default; hence, looking at all the changes you are comfortable with is recommended to do them all over again.
In this article, there are two ways shown to do so. They are mentioned below:
With the Use of Remote Control
Follow the below-given steps:
1. Click the ‘Menu’ button on the TV remote.
2. Now select the System tab.
3. Find Reset & Admin and set it.
4. Click on Reset TV to Factory Defaults.
This will ultimately lead to restarting your Vizio smart TV and showing all the default settings as if you have just bought a new one.
Without the use of Remote Control
Alternatively, you can also reset it without using the remote (if, in any case, it is not available). Here are the steps for the same:
1. Look for the available buttons on your Vizio smart TV (they could be behind your TV, or at the lower end, depending on the series of your Vizio TV)
2. While your TV is turned on, press and hold the volume down + Source buttons simultaneously till you get to see a memory/factory reset prompt on your Vizio TV.
3. Once you see the prompt, press and hold only the ‘INPUT’ button for about 10 seconds (you will then see another prompt on your TV showing that it’s being reset/memory is being cleared if done right).
Once the TV has been reset, let it turn on and proceed with the initial configuration. After this is done, your Vizio Smart TV should work perfectly well.
Contact the Vizio Support Team for Help
It is also likely that none of the above has worked, so it is suggested to contact Vizio Customer Support.
You must raise the issue and ask the Vizio customer service team for assistance. The essential customer service information is available on the Vizio Support website.
