Causes for LG TV Distorted Sound
Sound distortion in a TV device, regardless of its brand name or model, typically comes down to a few possible causes.
For starters, there could be a signal problem with the external source device. A poor connection between an outside source and your TV screen can cause the audio to distort.
You’ll know this is the case if your TV is a smart model and is linked to your phone or laptop.
You can check and see if that’s the case by disconnecting the source first and playing the sound there. In the event that the device’s audio seems distorted, then there’s your problem.
Sometimes your phone’s audio is working just fine, which means you should look into the TV instead. Often the cause is as simple as skipping a software update which leads to a few sound issues, so make sure your system is up to date.
However, if there aren’t any pending upgrades, then there might be a problem with the internal sound system. In this case, the issue can be quite hard to solve on your own, and it would be easier to consult with LG’s customer service or their technical team.
Just make sure that you know your TV’s model, serial number, and software version since you’ll be asked to provide this information as you fill out the help request.
How to Fix LG TV Distorted Sound
Now that we’ve covered what might be the cause of your problem, let’s dive into a few solutions you can do at home and that’ll surely fix your audio distortion.
Perform a Sound Test
A sound test should be the first troubleshooting task you perform. Each LG model should have this option available in the settings.
To perform a sound test, follow these simple steps:
- Access the side menu settings
- Choose the ‘all settings’ or the ‘support’ option, depending on the model name you have
- Go to general settings then click ‘additional settings’
- You may find the ‘additional settings’ choice in the support section too
- Click on the option ‘sound test’ to check your internal audio system
As the test takes place, listen closely to check if the distortion persists or not. You carry out this test in order to be certain that the issue lies with the TV itself and not otherwise.
In the window that asks you whether you can hear the sound clearly or not, click no so you can access your TV’s product information. Take this info to an LG technical support employee to help you further with your issue.
Check Your External Sound System
In case your TV is linked up to an external sound system, this might also be the cause for the audio distortion—just as we’ve mentioned above.
Faulty wiring or the inner circuits acting up could be a few issues that are messing up with your sound. If your TV passes the aforementioned sound test, it’s time to pursue a different route.
Here’s what you need to do:
- Access the settings menu
- Choose the ‘sound’ section in the menu
- Click on ‘sound out’
- Select the appropriate external speaker option
- Perform an external sound test
At this point, you need to make sure of two things: that your TV is accurately reading the external sound source and that the device is properly connected to your TV.
If the TV is linked to your home theatre or speaker system via Bluetooth, you should make sure that both devices are synced together. Sometimes disconnecting the system and then reconfiguring it with your TV will also work.
Do a soft reset
Often, simply doing a soft reset is enough to solve the issue. To do a soft reset, just remove the plug from the wall outlet and wait for at least 60 seconds before putting it back in again.
Do a factory reset
Another option you have is to do a factory reset. This will completely reset the TV to its factory defaults, so should be done as a last resort.
Here’s how:
- Using your remote control, press the Home button, then select the Gear symbol
- Select General
- Choose Reset to Initial Settings
- Press Confirm for the pop-up message
- Enter your password on the screen (if you forget the pin code, you won’t be able to reset your LG TV till you reset it)
- Don’t unplug the TV till the procedure is finished
How to Reset the Pin Code
Since you can’t reset your LG TV if you forget the pin code, it might come in handy to know how to change it.
Thankfully, there’s a hidden code to assist people who have forgotten their pins.
This is how you do it:
- From the Menu setting, select Settings
- Locate the Advanced Settings by scrolling through the Configuration Settings
- Scroll till you find the Safety page and select it
- You’ll see a Reset Password option (don’t press it, but just highlight it)
- On your remote, click channel up twice, then channel down, and channel up again
- Type 0325 or 0313 in the pop-up window
- In the screen that appears next, type 0000
- You should be able to modify your password now

Are you facing audio problems with your TV? If yes, then we hope our guide on LG TV distorted sound (causes and how to fix) has helped you identify the issue, and in turn, solve it.
The two main reasons behind the TV’s sound distortion can either be a weak signal connection between the TV and your external source or, an underlying issue with the device’s internal sound system.
Fortunately, both causes are rather simple to fix. If carrying out a sound test doesn’t work, however, consider filling out a form with the LG technical team. They can help you configure the audio distortion.
