No audio or sound on Vizio TV? How to fix

If Vizio TV shows pictures without audio, you could be facing a problem with the TV’s internal speakers or connected sound system.

But first, you need to check if the problem is consistent across different channels. Use your remote to shuffle between different channels and connected devices.

While at it, ensure that the volume isn’t muted on your remote control.

If the other channels have sound, then this is an issue with the specific channel(s). Unfortunately, there isn’t much you can do in this case except wait for them to fix it.

However, if all channels don’t have sound, then the issue is related to the speakers.

How to troubleshoot sound issues on Vizio TV

Luckily, you can fix most audio issues on your Vizio TV without having to involve a technician.

Here are some troubleshooting procedures you can perform to not only ascertain where the problem is coming from but get to take care of the Vizio TV sound issue once and for all.

#1. Inspect the TV

Temporary power and voltage issues might lead to a lack of sound on Vizio TVs. This is why it is advisable first to check your TV before attempting to try any other troubleshooting maneuver.

The good news is that all you need is a hard reset to fix issues brought about by a power surge.

Unplug your Vizio TV from the wall socket for about two minutes then plug it back in. This will help the TV power down properly and reset.

#2. Inspect the cables

Another common reason why a Vizio TV might show pictures but no sound is usually disconnected or faulty connecting cables.

This is why it is always best to check the cables before you attempt other fixes such as a hard reset. The main reason for doing this is to ascertain that all the wires are correctly connected.

If you are using replacement cables, it is good practice to switch them out with the ones you are currently using.

Switching cables, especially manufactured HDMI cables, is always the best way to go, as these manufacturer-provided cables are usually easily damaged.

If your HDMI cables are the source of the problem, replace them with quality options like the iVanky 4K cable.

#3. Inspect the feed

Here, you need to start by checking the source of the signal you are trying to display on your TV. Is your TV connected to the internet, cable box, or satellite?

After ascertaining the source, you now need to switch to a different signal provider and check if the sound comes back up.

For instance, if your Vizio TV is connected to the cable box, you can choose to connect it to the internet, satellite, or any other input device, such as a laptop.

If, by switching the signal source, the volume is restored, then you can rest assured that the issue was with the signal feed and not the TV. Here you only need to call the cable TV provider and have them fix the issue for you.

However, if you switch the signal feed but the sound is not restored, the cause of the issue might stem from several sources, including a problem with the TV hardware or settings.

#4. Examine external audio devices

Sometimes you might think the reason you can’t adjust the volume on your Vizio TV is an issue with the device itself when it is actually a faulty external audio device.

This is why you need to disconnect any external audio devices connected to the TV and test the sound issues using its in-built speaker system.

For instance, if you use a home theater system, Vizio speakers, or a soundbar as an external audio device, disconnect it and use the TV’s speakers to check if the sound is working.

If the sound comes back up, then the issue is with the external device and not the TV, and vice-versa.

#5. Change audio settings to default

Another reason why there might be no audio on your Vizio TV might be due to the audio settings on your TV. However, as serious as that might sound, it is something you can quickly fix by yourself.

To do this, all you need to do is access the audio settings on your Vizio TV and then adjust them accordingly.

You can quickly change every setting to default by simply pressing the reset button on the audio settings menu.

This is the best way to go, as the procedure will help fix any audio issues you might have without actually changing anything serious regarding the TV software.

#6. Factory reset the TV

A factory reset is another good way to try and address the TV’s audio issues. Keep in mind that a factory reset is only good at dealing with settings and software malfunctions.

Therefore, if a hardware issue is the cause of the audio problem, a factory reset will most likely not help. It will most likely not help with matters such as volume not working with remote.

To factory reset your Vizio TV:

  • Press the Menu key on your VIZIO remote
  • Choose System
  • Select Reset & Admin
  • Select Reset to Factory Settings
