Update software on Vizio TV

It is possible for your Vizio TV’s sound to stop working as a result of software issues. Keeping your TV’s software up-to-date is always a good idea.

In most cases, your Vizio TV will automatically check for and download new software updates as long as it is connected to the internet. The process of updating your TV can be interrupted occasionally, resulting in outdated software running on your TV.

Vizio TV software can be manually updated by following these steps:

  1. On your TV remote, press the V key
  2. The menu drop-down menu will allow you to select System
  3. Select Check for Updates from the menu
  4. If there are any updates available, your TV will start searching for them
  5. Confirm that the update has been installed if it is available
  6. You will need to restart your TV after downloading the update, install it, and restart again after it has been installed

Once your computer has restarted, check to see if the sound issue has been resolved. Alternatively, you can factory reset your TV if that doesn’t work.

Factory reset Vizio TV

After turning on the TV, click the Menu button.

The “System” option should be within the menu. Click it.

Select “Reset & Administration” then “Reset TV to Factory Defaults”. Before resetting the Vizio TV, the TV may ask for a code. There is a default code of four zeros, 0000, if it does.

Essentially, you will be restoring your Vizio TV to its original settings.

Factory reset Vizio TV without remote

Despite the fact that your Vizio TV lacks a remote control, you can still perform a factory reset.

You can do this by finding the power button on your TV. If your device has a right-hand side, left-hand side, or bottom button, you will find this on the right side, left side, or bottom.

Activate the TV by pressing and holding the volume down and source buttons simultaneously. Press and hold the input button for a few seconds after your TV prompts you to do so.

Keep pressing and holding the input button for a minimum of 10 seconds.

Turning off, rebooting, and factory resetting the TV will turn it off. It usually takes about a minute for the reboot and reset process to complete.

I’ve included some additional steps that might be worth trying before calling it quits if your sound issues have not been fully resolved at this point.

Reseat power cord in back of Vizio TV

Taking the power cord off the back of the TV could also solve the problem.

You should be able to hear the sound again once the TV comes back to life.
