VIZIO tv no sound – a complete troubleshooting guide

Vizio is a TV brand that was introduced in 2002, and quickly rose to popularity in the domestic TV market. Even though the TVs are made under Chinese license, Vizio is based in Irvine, California. Of course, no TV brand is flawless. 

Sometimes, Vizio TVs are afflicted with the problem of sound not working. Imagine watching your favorite show without any sound or not being able to change the volume to your preferences. 

There are hundreds of reasons why Vizio TV owners have suffered from this issue. But fortunately, there are also many solutions to this annoying problem, as we will discuss in detail below.

Vizio TV No Sound

If your Vizio TV is emitting no sound, make sure the TV is not muted. You can restore your TV audio with a soft or a factory reset. Updating the software can also fix the Vizio TV no sound problem. These are the basic solutions for your Vizio branded television. Alternatively, you can directly contact the Vizio support team or check your warranty.

How to Fix Your Vizio TV When There’s No Sound

These are some basic, and unknown fixes that you can perform in order to hear sound from your Vizio TV again. 

Confirm remote is working 

This is a no-brainer, but if the remote is faulty, it’s impossible to adjust the audio of your TV. To check the functioning of your remote, turn on the TV and press the volume button on the remote. You should also check to see if the batteries are working and replace them, if necessary.

Invest in a new Vizio remote in case it’s faulty. In the meantime, it’s possible to control your Vizio TV without a remote. 

Unplug TV from wall 

This is among the most common ways to get the sound working again. Simply unplug the Vizio TV from the wall socket, and wait for a full minute. The key here is to actually wait for 60 seconds. Be patient, and only plug it back to the wall socket once a minute is up.

This easy step enables the TV to soft reset itself. It is different than just switching the remote on and off. After plugging the TV to the wall socket, the sound will be heard in 80% of cases. 

However, the remaining 20% of cases are tricky, and demand more effort. So, try the below fixes if your Vizio TV is still not emitting sound. 

Update software 

Oftentimes, software issues can have affect your Vizio TV’s audio. Your TV should always be updated to the latest software. As long as the device is connected to the internet connection, it will automatically install new software updates. 

But sometimes, this procedure gets interrupted, which means the TV is stuck on old software. For manually updating the software, follow these steps:

  1. Press the V button on your remote.
  2. Choose System from the menu drop down.
  3. Now, choose Check for Updates, at which the TV will start to search for available updates.
  4. If there’s an available update, confirm the installation.
  5. The TV will download the software update and restart.
  6. After restarting, see if the sound problem is sorted out. 

If this solution didn’t bring any luck, try the following methods.

Unplug power cord from back of TV 

Another easy fix is to unplug the power cord from the back of the TV. Allow the power cord to be unplugged for a minute, and then plug it again. After plugging it back, ensure that the connection is solid. A tight connection is crucial to make sure that the TV is receiving stable power. 

After plugging it again, turn on the TV using the TV power button. Hopefully, the TV sound will come back to life.

Factory reset TV

If all of the above solutions have failed, it’s time to execute a factory reset. Remember that a factory reset doesn’t solve hardware issues – it’s only good for malfunctioning settings and software issues. 

Factory reset means reverting the TV back to the default position. You should note that a factory reset will erase the TV memory. This means that all settings (configuration, installed apps, and WiFi password) will be forever lost. 

With remote

With the TV on, press the Menu button. There will be a System button. Click it. Now, search for the “Reset & Admin“. From here, click on the “Reset TV to factory default“. Sometimes, the TV will ask for a code before doing the restart. In case it asks, the code is 0000

These steps can easily revert your Vizio TV to the default state. 

Without remote

If you don’t have your remote near you, it’s still possible to execute a factory reset. First, search for the power button on the TV. Based on the model you own, the location of the power button can be on the left, right, or the very bottom. 

With the TV on, press and hold down the power and volume buttons simultaneously. After a few seconds, your Vizio TV will ask you to press and hold down the input button. Do so for a minimum of 10 seconds.

Now, the TV will be turned off, rebooted, and a factory reset will be initiated. The reboot and reset process will only take a minute. For visual help, the YouTube tutorial below can be useful. Check it out:

This is how you can do a factory reset with and without a remote. But if the last resort did not help you either, below are additional fixes to consider.

Check your warranty 

This is a desperate last effort, but if there is no sound coming from your TV, check whether you have an active warranty on the device.

Explain your concern to the staff, and they will inform you whether this is covered under warranty or not. Your TV will either be replaced or repaired. Vizio also offers in-home services if this issue is covered under warranty. 

Contact Vizio support

If none of the troubleshooting steps have worked in your favor, contact the Vizio TV customer support team directly. Their number is 1-844-254-8087. Their working hours are:

Vizio TV No Sound – Quick TV Solutions

Confirm that the volume on the Satellite Box is above zero 

In case you are utilizing a satellite box or cable, check to see whether the volume is set higher than zero in the interference settings.

In this scenario, your cable box offers the audio and video signals that are ultimately transmitted via the TV, which might appear weird if you are a beginner at television settings.

When the cable box volume is set to zero, it instructs the TV to not play any sound. 

See if MTS or SAP is allowed on the TV

SAP is an abbreviation for Secondary Audio Programming. It’s possible to listen to the broadcast in anyother language with this feature. Secondary Audio Programming is a second audio stream added to the TV show.

The SAP can be turned off if you want to listen to your favorite shows in the original language. Famous labels for the TV audio menus are Audio Select, SAP, Menu, B-Audio, MS, or MTS.

Turn on the Vizio TV by pressing the Menu button on the remote. Select Audio from your list of possible options. Now, choose the Secondary Audio Programming choice. It might be titled as MS.

You can turn off the On setting. It may ask you to choose from Mono or Stereo from the menu. One of these will be SAP.

Verify whether the headphone jack is plugged in

This is a weird fix, but a possible one. Make sure that no headphone is plugged into the port on the Vizio TVs headphone jack.

While watching your television, it is possible that you mistakenly left a headphone plugged in. Since sound signals are only sent to the headset via this connection, the Vizio TV sound system is disabled. With care, unplug the headsets and check for the sound again.

Other Troubleshooting Methods

Check audio settings

Access the audio settings on the TV menu. It’s suggested to return them to the default setting by choosing Reset. Confirm and check the sound.

Check the feed (cable, internet, etc)

The feed refers to the signal source that is being displayed on the TV. It may be connected to satellite, internet, or the cable box. After confirming the source, switch to another signal provider. This can restore the sound. If it fixes the issue, it means that the problem was with the signal feed. 

Faulty or disconnected cables are a cause of no sound being emitted from the TV. Therefore, always check the cables before doing any far-reaching methods. 

If the cables have been moved, it can result in the sound issue. Ensure that all cables are secure and replace them if needed. In case you utilize an HDMI cable, replace it. 

Check external audio 

In case you’re using a surround sound or a soundbar, remove it and utilize the default speakers. If the problem is resolved, the cause was with the external hardware. If not, the TV is at fault.

Check other devices 

If you have another tech device, connect it to the TV. If there is sound with a gaming console, for example, the cause is either the HDMI port or a setting in the cable box. 

Check Secondary Audio Programming

It’s impossible to hear anything from the TV if it is set to Secondary Audio Protocol. 

Remove interference

There might be third-party device interference. The quickest way to confirm is to disconnect all devices plugged into the TV. Ensure that the default speaker mode is turned on. Play any channel. If still no sound is emitted, do the following:

  1. Unplug the TV from the power socket.
  2. Wait for some time, and plug it back again.
  3. Test for sound.

This is called a power cycle, and it helps if there is interference.

Why is the Sound Not Working on My Vizio TV

In this section, we have listed the most common causes when a Vizio TV loses sound. 

Mute/volume down 

It’s likely that you accidentally turned down the volume or muted it. So change that with your remote.

Faulty wiring 

Faulty cables are a major culprit in no sound coming from the TV. In that case, you’ll have to buy the new wiring.

Software needs updating 

An old software is capable of decreasing the sound performance. Try to update your TV to fix this problem.

Input issue 

If the input can’t be set up easily, there will be no sound. Try to disconnect all HDMI sources from the inputs and unplug the power from the TV. After ten minutes, it should work. If not, you might have problems with the hardware. 

Hardware issues

Finally, hardware problems can obstruct the sound from the TV’s in-built speakers. Do not try to solve this yourself, contact the experts.

Damaged mainland parts

Mainland or motherboard is the primary component of the TV. If it’s damaged, seek professional help instead of doing something yourself.
