Are you tired of enjoying your favorite TV show or movie only to be abruptly silenced by a mysterious sound cutout on your LG TV? You’re not alone. Many LG TV owners have reported experiencing this frustrating issue, and it’s not just limited to one specific model or generation of TVs. In this article, we’ll delve into the possible reasons behind the sound cutout problem on LG TVs and provide you with practical solutions to troubleshoot and fix the issue.
Software Issues: A Common Culprit Behind Sound Cutouts
Software glitches are one of the most common causes of sound cutouts on LG TVs. Like any electronic device, LG TVs rely on complex software to operate, and sometimes, these software programs can malfunction or become outdated. When this happens, it can affect the TV’s audio output, leading to sound cutouts.
Firmware Updates: The Solution to Many Problems
One of the most straightforward ways to resolve sound cutouts caused by software issues is to update the TV’s firmware. Firmware updates can fix bugs, improve performance, and enhance overall functionality. To check for firmware updates on your LG TV, follow these steps:
- Press the “Home” button on your LG TV’s remote control.
- Scroll down to “Settings” and select it.

HDMI Connection Issues: A Common Cause of Sound Cutouts
HDMI connections are notorious for causing sound cutouts on LG TVs. HDMI (High-Definition Multimedia Interface) is a digital interface that transmits both audio and video signals between devices. However, when these connections are loose, damaged, or faulty, they can disrupt the audio signal, leading to sound cutouts.
HDMI Cable Issues: Check Your Cables
When it comes to HDMI cables, the problem often lies with the cable itself. Here are some common issues to check:
- Damaged or bent cables: Inspect your HDMI cables for any signs of damage, such as cuts, bends, or pinched wires. If you find any damage, replace the cable.
- Loose connections: Ensure that all HDMI cables are securely connected to both the TV and the external device (e.g., Blu-ray player or gaming console).
- Incompatibility: Verify that your HDMI cables are compatible with your devices and the TV. Some devices may require specific HDMI versions or speeds.
Audio Settings: A Possible Cause of Sound Cutouts
Sometimes, sound cutouts can be attributed to incorrect or misconfigured audio settings on your LG TV. Here are some common settings to check:
Audio Output Settings: Check Your Settings
Ensure that your TV’s audio output settings are correctly configured:
- Press the “Home” button on your LG TV’s remote control.
- Scroll down to “Settings” and select it.
- Select “Sound” and then “Audio Output.”
- Verify that the audio output is set to the correct device (e.g., internal speakers, external speakers, or soundbar).
Audio Format Settings: Check for Compatibility
Some audio formats may not be compatible with your TV or external devices, leading to sound cutouts. Check your TV’s audio format settings to ensure they’re compatible with your devices:
- Press the “Home” button on your LG TV’s remote control.
- Scroll down to “Settings” and select it.
- Select “Sound” and then “Additional Settings.”
- Verify that the audio format is set to a compatible option (e.g., PCM, Dolby Digital, or DTS).
Hardware Issues: A Less Common but Still Possible Cause
While less common, hardware issues can still cause sound cutouts on LG TVs. Here are some potential hardware-related culprits:
Faulty or Damaged Speakers
If you’re using your TV’s internal speakers, a faulty or damaged speaker can cause sound cutouts. Inspect your TV’s speakers for any signs of damage or wear. If you find any issues, consider replacing the speakers or using external speakers instead.
Defective or Faulty Sound Component
In some cases, a defective or faulty sound component within the TV can cause sound cutouts. If you’ve tried all other troubleshooting steps and the issue persists, it’s possible that the TV’s sound component is faulty. In this case, you may need to contact LG support or a professional TV repair service.
Troubleshooting Tips and Tricks
In addition to the above causes and solutions, here are some general troubleshooting tips and tricks to help you resolve sound cutouts on your LG TV:
Power Cycle Your TV
Sometimes, a simple power cycle can resolve the issue. Turn off your TV, wait for 30 seconds, and then turn it back on.
Reset Your TV’s Sound Settings
Resetting your TV’s sound settings to their default values can sometimes resolve sound cutouts. To do this:
- Press the “Home” button on your LG TV’s remote control.
- Scroll down to “Settings” and select it.
- Select “Sound” and then “Reset Sound Settings.”
Check for Interference from Other Devices
Other devices in your home can sometimes interfere with your TV’s audio signal, causing sound cutouts. Try moving other devices away from your TV or switching them off to see if the issue resolves.

Why does my LG TV’s sound keep cutting out?
The sound on your LG TV may keep cutting out due to a variety of reasons. One possibility is that the issue lies with the TV’s settings or configuration. It’s possible that the TV’s audio output is set to an incorrect mode or is not compatible with the connected device. Another reason could be a problem with the connected device itself, such as a faulty soundbar or home theater system.
In some cases, the issue may be related to a software or firmware problem with the TV. Outdated software can cause audio sync issues, leading to sound cutouts. Additionally, physical obstructions or interference from other electronic devices can also cause sound cutouts.
How do I reset my LG TV’s audio settings?
To reset your LG TV’s audio settings, go to the TV’s settings menu and select the “Sound” or “Audio” option. From there, look for the “Reset” or “Default” option and select it. This will restore the TV’s audio settings to their default configuration. Alternatively, you can also try resetting the TV to its factory settings, which will reset all of the TV’s settings, including the audio settings.
It’s also a good idea to check the TV’s audio output settings to ensure that they are set correctly. Make sure that the output is set to the correct device, such as the TV’s internal speakers or an external soundbar. If you’re using an external device, ensure that it’s properly connected and configured.
What are some common audio settings I should check?
Some common audio settings to check include the TV’s audio output mode, Dolby Digital or DTS settings, and the audio format. Ensure that the audio output mode is set to the correct device, such as PCM or bitstream. If you’re using a soundbar or home theater system, ensure that the TV is set to output audio in the correct format, such as Dolby Digital or DTS.
Additionally, check the TV’s audio delay or lip sync settings, as an incorrect setting can cause sound cutouts. You can also try adjusting the TV’s audio processing settings, such as the equalizer or surround sound settings, to see if it resolves the issue.
Could a software update fix the issue?
Yes, a software update can potentially fix the issue. If the TV’s software is outdated, it may be causing the sound cutouts. LG regularly releases software updates to fix issues and improve performance, so it’s a good idea to check for updates regularly. To check for updates, go to the TV’s settings menu and select the “Software” or “Firmware” option.
If an update is available, follow the on-screen instructions to download and install it. After the update is complete, test the TV’s audio to see if the issue has been resolved. If the issue persists, you may want to consider contacting LG support for further assistance.
What if I’m using an HDMI connection?
If you’re using an HDMI connection, the issue could be related to the HDMI handshake process. The HDMI handshake is the process by which the TV and connected device negotiate the audio and video settings. If the handshake process is interrupted, it can cause sound cutouts.
Try disconnecting and reconnecting the HDMI cable, or trying a different HDMI port on the TV or connected device. You can also try setting the TV’s HDMI input to a different format, such as HDMI 2.0 or HDMI 1.4, to see if it resolves the issue.
Could a faulty HDMI cable be the cause?

Additionally, ensure that the HDMI cable is securely connected to both the TV and connected device. If you’re using a long HDMI cable, try using a shorter one to see if it resolves the issue. You can also try using an HDMI switch or splitter to see if it improves the signal quality.
What if the issue persists after trying these troubleshooting steps?
If the issue persists after trying these troubleshooting steps, it may be a sign of a more serious problem with the TV or connected device. In this case, it may be best to contact LG support or a professional TV repair service for further assistance.
They can help diagnose the issue and provide a solution or repair options. Additionally, if the TV is still under warranty, you may be able to get it repaired or replaced for free.
