LG TV No Sound – How to Fix It?

If your LG TV has no sound, you must follow simple steps. First, unplug your TV from power and wait for 60 seconds. After that, press and hold the power button for additional 30 seconds. After those two steps, plug your TV back into power, and it should work again.

1. Unplug a Television from the Wall Socket

Even if you have already tried to unplug your TV, ensure you follow the exact procedure. Without proper steps, this easiest step does not have to work, and your LG TV won’t turn on.

Make sure you identified the correct cable which is coming from your TV. With TV, many other devices are plugged into the same socket or power cord, and you need to make sure you are disconnecting the correct cable.

Once TV is disconnected, wait at least 60 seconds. In the meantime, you can search for the power button. Once 60 seconds is up, you can press and hold the power button for additional 30 seconds.

This procedure will ensure that all residual energy that remains in your TV is gone and all parts of the TV are properly turned off.

Many people do not realize that even when the TV seems to be off, some parts are always powered while the device is plugged into the socket.

Once you have completed both steps, you can plug your TV back into the socket, and it should work again!

If you belong to a small group of people for which this procedure did not resolve the issue completely, check the other fixes below.

2. Check the Audio Output Setting in Your LG TV

There are multiple use cases where you want sound from a different device than your TV.

You can have an external home theater sound system, or you can have an external soundbar. Both those options usually produce better sound than your TV.

If your LG TV is not producing sound, it is worth checking if your sound settings are set for TV Speakers.

To make sure your sound settings are correct, follow those steps:

  • Press the Settings button on your remote control
  • Go to Sound
  • Go to Sound Out
  • Make sure you select Internal TV Speaker

Suppose you have an external sound system like a soundbar or home theater, then you can try all other options there. A different setting can be a better option in your particular case.

3. Run a Self-Diagnosing Sound Test

You should make sure an external device does not cause the problem. One way to do that is to run a diagnostic test for sound, which is built into your LG TV. 

For WebOS 6.0 devices, you can run a self-diagnostic test by following those steps:

  • Press the Settings button on your remote control
  • Go to All Settings
  • Go to Support
  • Go to Quick help
  • Go to Check Items
  • Select Self-Diagnosis of TV Settings
  • Select Sound
  • Select No Sound from category list

For WebOS 5.0 devices, you can run a self-diagnostic test by following those steps:

Press the Settings button on your remote control
Go to All Settings
Go to Support
Go to Additional Settings
Select Sound Test

For WebOS 4.5 and older devices, you can run a self-diagnostic test by following those steps:

Press the Settings button on your remote control
Go to All Settings
Go to Sound
Select Sound Test

Once the test is completed, you will get results. If an issue is detected, proceed with resetting your sound settings altogether.

You can reset sound settings following those steps:

  • Press the Mute button on your remote control 3 times
  • Select AV Reset
  • Resetting AV values message will appear on top of screen on your TV

5. How to Factory Reset LG TV without Remote Control

Many do not know that, but you can reset your LG TV to factory default settings without the original remote control unit.

The first thing you need to do here is to find a power button and try to press and hold it for at least 10 seconds. Some models will factory reset this way. If this does not help your LG TV model, then use a small joystick-like control on your TV to navigate the menu.

Once you have located your control buttons, power up your TV and follow those steps:

  • Navigate to Menu
  • Go to Settings
  • Go to General
  • Select Reset

If you can not find control buttons or if you face other issues, try the following tips.

Look around the house. You can have the universal remote control unit to control your LG TV as well as other devices.

If you have LG Smart TV, you can control your television with the app installed on your Smartphone. Go to the Play store on Android devices or the Apple store on your iPhone and install the LG ThinQ app.

If you have a USB Keyboard in your house (your desktop PC usually has one), plug it into your LG TV, and you can control it with any USB keyboard.

6. Update LG TV Operating System

It is not secret that modern Smart TVs are small computers. It means they are running on various operating systems. Those systems are very complicated and can require regular updates to fix different kinds of issues. 

Before starting with this tip, you must ensure your LG TV is connected to the internet with a LAN network cable or over Wi-Fi.

You can check if you are connected to the internet by browsing Youtube videos on your TV. If Youtube is working, you have the internet on your TV.

Follow the steps below to update the software on your LG TV:

  • Press Settings button on the remote control
  • Go To All Settings
  • Go To General
  • Select About This TV
  • Select Check for Updates
  • If there is new update proceed with updating your TV by pressings Download and Install button
Update LG TV Operating System

It is perfectly fine if this process takes a couple of minutes. Be patient and leave the TV without any interaction until it informs you about a successful finish.

7. Check for Broken Cables and Loose Connections

If changing settings on your LG TV does not help, check for issues outside of the TV as well. 

Wrong cables or loose connections can also cause screen flickering. 

Right now most used data signal cable is HDMI.

Check back of your TV and look for connectors named HDMI Input (or just HDMI IN).

If you have more than one cable plugged into the HDMI IN connector, check the right one. 

The picture should disappear once you disconnect the right cable.

The easiest thing to do here is to replace your HDMI cable with another one. Do that first if you have an additional HDMI cable lying around.

Usually, an HDMI cable is used to connect the desktop PC and computer screen. You can use this HDMI cable to troubleshoot your TV.

If you have just one HDMI cable in your house, make sure you follow those steps:

  • Check visually if the cable is in good shape
  • Unplug and plug in both sides of the cable

HDMI cables are cheap; if you are not sure your cable is 100% fine, then it is a good idea to buy a new one anyway.

8. Contact LG TV Support
