Meanwhile, you can do a few items at home if you have acquired an LG tv and are worried about its sound quality. No sound on your LG TV? Here are some fast remedies you may try.

A Full Hard Reset Is the Best Begin

The only option left is to do a complete system reset when all else fails. Follow these steps to do a hard reset on your LG TV:

  • Preparing for a hard reset on your TV by turning the power off is better than keeping it on.
  • Until further notice, please be patient.
  • It is time to plug in your power cord again.

Try doing a factory reset on any connected devices to get the sound back. Your television’s satellite and cable connections should be checked out.

It Is Possible To Reset The Visual And Audio Settings

Following these procedures will allow you to restore the default audio-video settings if you find the configurations too confusing.

  • Your TV remote’s mute button may be pressed three times. A pop-up window should appear on your TV.
  • Confirmation is required.

Default Settings Can Be Restored From The Factory

Performing a complete factory reset may be necessary if a simple audio reset doesn’t resolve the issue. Your remote’s “Home” button should be pressed. The TV’s settings menu may be accessed by pressing the “cog” icon in the top right of the screen.

A dropdown menu will appear; choose “General.” From the dropdown menu, choose “Reset to original settings.” The following processes may differ after hitting the “reset to original settings” option on your LG smartphone. 

For a Long Time, Updates That Were Due

Because they might conflict with your settings, pending updates can sometimes create issues like the lack of sound on your LG TV. Update the firmware on your device to reverse the effects of a previous operating system.

  • You may go back to the main menu by pressing “home” on your keyboard.
  • You may enter your TV’s settings menu by pressing the “cog” icon in the top corner of the screen.
  • Use the “All settings” option in the bottom-right of your screen.
  • On the left, you’ll see an item labelled “General Menu.”
  • The “About with this TV” option may be found at the bottom of a page for this television.
  • Select the “Allow regular updates” option from here on out.
  • The “Check for changes” function should be used often.
  • Read the LG TV installation instructions whenever a new feature is made available.

Examine At Your Audio Channels

Perhaps the issue isn’t with your software but with how you set up your system’s audio channels?

“Audio Channels” refer to the numerous audio output devices connected to your television. The TV audio may be tested for errors by examining the sound channel it is being transmitted to.

HDMI may have recently been used with an “S” video cable. No sound is made by these lines, which are only used to transmit visual data. Then, make sure that an audio cable is connected.

If you’re utilizing an HDMI cable, switch to a new one.

Connected Devices’ Configuration Should Be Checked Before Using The Service

The internal settings of satellite and cable boxes may be accessed if you are connected to such devices. If your LG TV isn’t producing any sound, you may use the sound settings on these devices to figure out if the issue is with the TV itself or something else.

Disconnect everything but the TV’s built-in speakers and run a quick test.

Afterwards, you may check the audio parameters of each device connected and see whether their internal speakers are working as advertised.
