Perhaps when you turn on your Vizio TV again, you suddenly have a question: why does my Vizio TV have no sound?

If you find out that your TV has started to malfunction, this article will give you some simple instructions on how to fix Vizio TV no sound.

The Vizio TV sound may be bouncing if any of the sound settings are incompatible with your device. But the list of possible problems is not limited to this. It could be faulty firmware, a broken volume button on the remote, a badly connected or damaged cable, or a Vizio TV sound settings failure.

Dust or debris under the buttons or improper connections between the remote and the Vizio TV can also be the problem.

Below you’ll find all the information available about these problems and how to fix them. You will also learn how to make the Vizio TV volume optimal for your ears, as well as how to display it on your Vizio TV screen.

Vizio TV No Sound

You are tired after a long day and decide to watch TV. But suddenly you find that Vizio Smart TV is interfering with your viewing experience. You are surprised to find that the Vizio TV sound is working as if for nothing or not at all. You try to fix the problem with the remote, but all to no avail.

Basically, there are three factors why Vizio TV no sound. First, check the volume control to see if it’s at zero or turned to the minimum. Then check to see if the headphones or TV speakers that are currently turned off are connected to the Vizio TV. Also, don’t be lazy to check if the Vizio TV speakers themselves are turned on.

In the first case, simply turn up the volume using the keys on your remote control. In the second case, simply disconnect the headset from the Vizio TV. In the third case, open the Vizio TV Settings and then turn on the Vizio TV speakers.

If none of these tips worked and Vizio TV no sound, restart the Vizio TV. First, turn it off, then unplug it, plug it back in, and turn it back on.

Vizio TV Sound Keeps Changing

Volume problems, such as sudden volume drops, are usually caused by some device conflicting with Vizio TV. This is easy enough to check. Simply turn off all devices and check the volume in all Vizio TV applications. Most often the problem lies in the SRS TruVolume feature.

Disable SRS TruVolume Function

SRS TruVolume is a feature that controls the volume so that you can experience sound comfortably. On the one hand it is very convenient, but on the other hand it often conflicts with the settings of your Vizio TV.

That’s why, more often than not, disabling this feature solves your Vizio TV no sound problem. Follow our instructions to do this.

1. Locate the Menu button on the remote control and press it.
2. Open the Audio Settings tab, and select the Advanced Audio Settings option.
3. Turn off the Automatic Sound Control feature.

Also check the other audio settings that can control the sound automatically. These, too, can cause the sound to fluctuate. For example, check whether surround sound and volume leveling are enabled.

Remember to also check all audio settings on your other devices connected to the Vizio TV. Turn off automatic sound control everywhere. This includes your set-top box, game console, and connected speakers. If after all these steps, nothing has changed and Vizio TV no sound, then below we will look at a few more ways to fix this problem.

Hard Reset TV

A hard reset will allow your Vizio TV to get rid of all the extra data that is weighing on its performance. This feature is also useful because it doesn’t delete all your preloaded data and settings, so you can safely use it to solve Vizio TV no sound problems.

Step 1: Unplug all the devices connected to your TV first, and then the TV itself.

Step 2: Unplug the power cord.

Step 3: Press and hold the power button on the TV for about thirty seconds.

Step 4: You can safely go about your business, for ten minutes.

Step 5: Then plug the TV back in and turn it on.

Factory Reset

A factory reset is the most extreme method of getting rid of almost any Vizio TV no sound problem. But it’s worth remembering that while it’s effective, it will restore your Vizio TV to its original settings as well as roll it back to the first version of the firmware.

In addition, if you do a factory reset you will remove all of your activity as well as all of the content you downloaded. You should only do a factory reset when all other methods have been tried. If this is your case, here’s a detailed guide on how to do it right. Here is detailed manual how to reset vizio tv.

Step 1: Open the Vizio TV menu by pressing the appropriate button on the remote.

Step 2: Go to the Settings tab and find Reset and Administration.

Step 3: Click on Reset to factory settings.

Step 4: Type in the Vizio TV password that you set. If you didn’t set your password, enter the default password. The default is 0000.

Step 5: Click the Reset button in the window that appears.

Step 6: Do not turn off the Vizio TV until the entire procedure of the factory reset is completed, only then can you reconfigure it to your liking.

Please note that if the Vizio TV no sound problem is due to incorrect operation of the new firmware version, you should not use this method. Just wait for the release of a new update. If the Vizio TV no sound problem with the upgrade will not be solved, then use this method.

Update the TV’s Firmware

It is possible that your Vizio TV currently has firmware that has a bug or a nasty bug in its code. If Vizio support receives a lot of bug reports in the current firmware, they will quickly find and fix them by releasing a new update.

More often than not, the Vizio TV finds the new update for itself and automatically installs it. If you found out that the new firmware is out, but your Vizio TV did not update itself, we suggest you do the following.

Step 1: Take hold of the Vizio remote control and press the Menu button.

Step 2: Open the Settings screen and click on the Check for Updates tab.

Step 3: If the screen shows that an update is available, all you need to do is press the confirm button to have it installed.

Check your Cables

If the sound gives out a glitch or Vizio TV no sound at times, chances are you have a problem with the cable box. It could be broken or just loose. The problem could lie in any cable box from HDMI port to coaxial cable. For starters, try disconnecting all the cables and putting them back in cable box. Try to squeeze them tightly.

If that doesn’t help with the Vizio TV no sound problem, then remove the cable from your Vizio Smart TV and try plugging it into another. Or buy a new cable and test on it. You should also read your TV’s manual carefully to see if this cable fits your TV’s audio signal.

Vizio TV Surround Sound Volume Won’t Turn Up/Down

If you have problems with the Vizio TV volume control, it is worth checking the operation of the remote control or the buttons on the Vizio TV itself. First, try to buy new batteries and put them in. But remember that if the TV audio problem lies in the batteries, then none of the buttons on the remote control will perform their function.

If the only problem is with the volume buttons, you may have dust and debris accumulated under them, or you just need to reset the remote. You can do this as follows.

Step 1: Remove the batteries from the remote.

Step 2: Press each button on the TV remote one time. This will help remove any remaining power from the remote and help reset it.

Step 3: Squeeze the volume buttons a couple of times to get rid of any excess debris underneath them.

Step 4: Reinsert the batteries and see if the buttons work.

There is also the possibility that you are not using the standard Vizio remote, but a remote from another company. For other remotes to work properly, they need to be paired with the TV at all times. You can read about how to do this in any remote’s manual that comes with it.

If the volume buttons on the Vizio TV itself have failed, try pressing them a few times to shake out any debris. If this does not help, then refer to our advice in the paragraphs above. In particular, activating a hard reset will work for you in that case.

Vizio TV Volume Low

You can manually adjust the sound of your Smart TV to adapt and optimize it according to your preferences or according to the type of sound you are listening to. You won’t work miracles, but you will get small improvements that you will notice in some movies and productions.

You can change it while listening to music, watching a movie, etc. D. In general, you will just have to use the Vizio TV controls and access to the settings to find different options.

It will depend on the model and brand in question, but you can find some modes already configured as “standard”, “optimized” or “enhanced”, and you will also find a manual adjustment option where you can change or modify the different settings.

In addition to viewing the aforementioned options, some televisions offer you to change or activate the “dialogue enhancement” feature.

What this technology allows is that it will make it easier for us to understand what they are saying on Vizio TV, whether they are contest hosts or the actors and actresses of a soap opera.

Another feature you can activate is dynamic comprehension or automatic volume. In this case, what we are doing is that television makes all sounds more or less similar in volume.

Of course, it has happened to you that some sounds or moments are heard too quietly and others sound too loud. We recommend watching Vizio TV at night: there will be no unexpected shocks, and you won’t have to change it manually.

In some situations the sound is audible, but the volume level is extremely low. The causes of such a malfunction are divided into 4 main groups:

Incorrect audio settings – mainly this problem is encountered by Smart TV owners;

Hardware malfunction – breakage of speakers, boards, wires and chips can also lead to the fact that the sound does not work in the Vizio TV, or it became too quiet;

Central processing unit failure – problems with the performance of this module occur as a result of short circuits caused by regular voltage fluctuations;

If you use an additional playback device, such as a laptop or PC, be sure to check the volume settings on it.

Other Problems with the Sound on Your Vizio TV

We have considered situations in which the Vizio TV shows but no sound, but sometimes there are problems with acoustics of an unusual nature.

The TV turns on, but there is no picture or sound. The source of the problem may be a trivial failure to start or turn off, or breakage of the board.

The first thing to do is to unplug the TV, wait 10 minutes and plug it in again. If this does not help, it may be a problem with the operating system, try to install new firmware on it. The last option is a failure.

The TV screen is black, but there is sound in some application, more often in the player. Can be a simple program failure or an indication of the lack of support for a particular codec.

The sound disappears at certain intervals and then appears. Most likely one of the TV elements is overheating. You need to have it repaired.

Sound Appears After a While

When you turn on the TV, sound may not be heard immediately. However, the operation resumes after a few minutes. There are two reasons for this behavior:

• Power supply failure – requires diagnosis and repair.
• Damaged contact.

The last reason requires a little explanation. Let’s assume that the contacts are damaged and there is a micro gap between them. During operation, the device gradually heats up, causing the metal contacts to expand and make contact.

The sound reappears, and this continues until the unit shuts down and cools down. The contacts will separate again. The problem is not critical, but gradually the fault will only get worse and you need to call a specialist.

Sound is Lost While Watching

If your TV loses sound while you’re watching, there can be a variety of reasons for the lack of sound in your TV. If you smell something burning, it means that the signal amplifier or microprocessor responsible for the sound has burned out.

In this case, turn off your TV immediately, unplug it and contact a service center.

If your TV intermittently loses sound and then recovers, it means that one of its electronic components overheats and then, as soon as it cools down, turns back on.

This component will sooner or later burn out completely, and one way or another you will have to repair the sound of your TV.
