LG TVs donโ€™t falter easily but can run into technical glitches. One such issue is the LG TV sound not working, which makes it impossible to watch any content on the TV.

Often, the issue occurs due to poor sound configuration, but can also occur due to faulty hardware and outdated software.

In this post, weโ€™ll share the primary reasons behind the LG TV audio problem. Youโ€™ll learn multiple methods to troubleshoot the audio and get it working again.

Common Reasons for LG TV No Sound Issue

Here are a few reasons why you arenโ€™t hearing any sound from the TV:

  • Faulty cables or incorrect cable connections
  • Mute or very low-volume settings
  • Misconfigured audio settings
  • Hardware malfunction in the external speaker, port, or in-built speaker

9 Methods to Fix No Sound Problem in LG TV

We have curated an exhaustive list of all the solutions that you can try to restore the LG TV sound. Follow the methods in a linear fashion.

1. Play With Volume Levels

Some TV channels and media sources have very low audio output. As a result, you might not hear anything in low-volume settings. Crank up the volume levels and check multiple channels to see if the audio works.

Sometimes, the media file youโ€™re trying to play has no audio or is corrupt. So, the video part works fine, but you wonโ€™t hear any audioโ€”test volume settings with multiple channels and media sources. Run YouTube and streaming apps to confirm whether the speaker is working.

2. Check Physical Connections

Loose or damaged cable can result in poor-quality audio or no audio output. Inspect all the cable connections, including the set-top box and speakers. Look for signs of damage on the HDMI, auxiliary, and optical cables and replace them if necessary.

3. Select the Correct Audio Output Device

If you are trying to play audio via HDMI but donโ€™t have an external speaker, it wonโ€™t work. You must check the sound settings and select the correct audio output device:

Step 1: Press the Settings button on the remote.

Step 2: Go to Sound > Sound Out section.

Step 3: Select the sound output device from the list (the internal speaker or an external device).

Step 4: Close the Settings and test the audio playback.

Note: Some settings might appear under different sub-menu in the various versions of WebOS.

4. Do a Sound Test

LG TVs with WebOS come with a Sound Test option. It is a diagnostic tool that plays a sound to check the in-built speakerโ€™s condition. Hereโ€™s how to do it:

Step 1: Press the Settings button on the remote.

Step 2: The Sound settings appear in different sections based on the WebOS of your LG TV.

  • WebOS 4.5 or older – Navigate to All Settings > Sound > Sound Test.
  • WebOS 5 – Navigate to All Settings > Support > Additional Settings > Sound Test.
  • WebOS 6 – Go to All Settings > Support > Quick Help > Check Items > Self-Diagnosis of TV Settings. Select Sound > No Sound option.

The TV will play a sound to check the in-built speaker. If you do not hear any audio, move to the next step.

5. Change Audio Output Mode

If you use an external audio device with a TV that doesnโ€™t play audio, change the audio output to a different mode. Soundbars have multiple connection options, including HDMI, optical cable, and Bluetooth. The HDMI port or another connection mode may be faulty.

Swap connection modes (change from Bluetooth to HDMI or vice versa) and check if the audio playback works. Also, try to play the audio from a different device, like a mobile phone, to the speaker or soundbar.

6. Do an A/V Reset

If you have accidentally misconfigured the audio/video settings, you must do an A/V reset on the LG TV. It will revert to the default audio and video settings. Hereโ€™s how:

Step 1: Press the Mute button three times to open the menu.

Step 2: Select the AV Reset option. Wait for the reset to complete.

Step 3: Restart your LG TV and check if the audio output works.

7. Update the TV

An outdated version of WebOS on your LG TV can result in audio playback problems in apps and connected devices. So, you must update it to the latest version that contains a patch for all the bug fixes and supports all the latest apps and devices.

Repeat the following steps:

Step 1: Press the Settings button on the remote.

Step 2: Go to Go to All Settings > Support > Software update.

Step 3: Select the Check for Updates option.

Step 5: Restart your TV to apply the new update.

8. Factory Reset

Step 1: Open the Settings using the remote button.

Step 2: Navigate to All Settings > General > System.

Step 3: Select the Reset to Initial Settings option.

Your TV will reboot to apply the changes. Follow the on-screen instructions to pair the TV remote and sign in to your account.

9. Reach Out to Customer Support
