Perform An Audio Test

To check the audio on your LG TV, perform a simple audio test. Here’s what you need to do:

  1. Go to Settings – All Settings.
  2. Go to Support – Additional Settings.
  3. Choose ‘Sound test’.

A sound test will set your volume to 20 automatically. If you hear sound, you’re good. If not, read on!

Turn Volume Up

One of the first things to check is the volume on your TV. Often, people think their TV has no sound when it’s simply been turned down too low. To adjust the volume on your LG TV, you can use the buttons on the TV itself, the LG TV remote app, or the buttons on the side of your TV (if it has them).

Audio Settings

If the volume is turned up and you’re still not hearing anything, the next thing to check are the audio settings on your TV. On most LG TVs, you can access the audio settings by pressing the “Settings” button on your remote control and then navigating to the “Audio” or “Sound” section of the menu.

From here, you can adjust the volume and make sure that the TV’s built-in speakers are enabled. You may also want to check the “Balance” settings to make sure that the sound is evenly distributed between the left and right speakers.

Audio Output

If the audio settings on your LG TV are correct and you’re still not hearing any sound, there may be a problem with the audio output on your TV. This could be due to a faulty HDMI cable, a problem with the TV’s audio output port, or an issue with the device that you’re trying to connect to your TV.

To troubleshoot this issue, you can try a few different things. First, unplug the HDMI cable from both your TV and the device that you’re trying to connect (such as a cable box or game console), and then plug it back in again. This can sometimes reset the connection and fix any issues.

If that doesn’t work, try using a different HDMI cable to see if the problem is with the cable itself. You can also try using a different audio output port on your TV, if it has more than one.

External audio device

If you’re using a soundbar or other external audio device, make sure it’s turned on and properly connected to your TV.

A cable might also be the issue. Make sure you’re using the correct cable. Here’s how to check and adjust this setting:

  1. Go to Settings – Sound.
  2. Click ‘Sound Out’.
  3. Make sure the correct cable type is marked.

There is a wide range of external soundbars available. Of course, LG has its own soundbar. However, we think this JBL 9.1 is the very best soundbar (for TVs). Why? What we like about this sound system is that the sides of the speaker are mobile. This means that they can be placed in other places in the house. For example, behind your head, on the couch. In our opinion, this is ideal for creating fantastic Dolby surround sound without much hassle.

This is the ideal for movies or Netflix series. When we fully turned the subwoofer on for the first time, we were really positively surprised. What a sound! What an experience! The downside of this speaker is definitely the price, in our opinion. It is not the cheapest sound system, but if you often watch movies, series and sports, this soundbar is definitely worth the money. Want to spend less? Then check out this JBL 5.1 on Amazon.

Contact LG Customer Support

If you’ve tried all of the above steps and you’re still not hearing any sound on your LG TV, there may be a problem with the TV itself. In this case, it’s best to contact LG customer support for assistance. They can help you diagnose the issue and determine the best course of action, whether that means repairing or replacing your TV.

No Sound On Screen Mirroring LG TV

Whether you’re mirroring from your iPhone, iPad, MacBook or Android to LG TV, you may be wondering how to get the sound to work. The good news is that it’s actually pretty simple – all you need to do is mute your phone and turn up the volume with the LG remote control. This way, the sound will come through the TV speakers instead of your phone, and you’ll be able to enjoy your content without any issues.

Of course, if you’re not using screen mirroring and just want to watch TV, you can also use the mute button on the remote control to mute the sound completely. Either way, it’s easy to get the sound working on your LG TV.

Can firmware updates on LG TVs affect sound settings or performance, and how can I check for and apply these updates?

Firmware updates can indeed impact sound settings and performance on LG TVs. It’s advised to regularly check for updates to ensure the TV operates with the latest software, offering improved functionality and possibly resolving existing sound issues. The TV menu typically includes an option to check for and apply firmware updates.

The audio format plays a crucial role in sound output quality. LG TVs support various formats, but selecting one that matches the content’s original format usually results in the best sound experience. Consult the TV’s manual or settings menu for information on supported formats and how to select them.

Are there specific troubleshooting steps for LG TVs connected to external audio systems, like soundbars or home theater systems, when experiencing no sound?

When LG TVs are connected to external audio systems, such as soundbars or home theater systems, and no sound is experienced, checking the audio output settings on the TV is essential. Ensure the TV is configured to output sound through the correct external device. Additionally, verifying the connections and settings on the external audio system itself can resolve sound issues.


In conclusion, if your LG TV has no sound, there are a few potential causes and solutions to try. First, make sure the volume is turned up and the audio settings on your TV are correct. If that doesn’t work, try resetting the HDMI connection and using a different HDMI cable or audio output port.

If all else fails, contact LG customer support for assistance. By following these steps, you should be able to fix the issue and restore sound to your LG TV.
