Are you tired of hearing an annoying buzzing noise coming from your LG TV? You’re not alone! Many people have reported this issue, and it can be quite frustrating, especially when you’re trying to enjoy your favorite show or movie. But fear not, dear TV enthusiast, for we’ve got the solutions to help you quiet that pesky buzz and get back to your viewing pleasure.
The Possible Causes Of The Buzzing Noise
Before we dive into the fixes, it’s essential to understand what might be causing the buzzing noise in the first place. Here are some possible culprits:
Loose Connections
One of the most common causes of a buzzing noise on an LG TV is loose connections. Check your HDMI cables, power cord, and any other cables connected to your TV. Make sure they’re securely plugged in and not loose. Even a slight movement or vibration can cause the connections to become loose, resulting in a buzzing noise.
Electrical Interference
Electrical interference from other devices in your home can also cause a buzzing noise on your LG TV. This is especially true if you have devices with motors, such as refrigerators, air conditioners, or fans, nearby. These devices can generate electromagnetic fields that can interfere with your TV’s signal, causing the buzzing noise.
Power Supply Issues
The power supply unit (PSU) in your LG TV could be malfunctioning, causing the buzzing noise. If the PSU is faulty, it may not be able to regulate the power supply properly, resulting in a buzzing or humming noise.
Firmware Issues
Outdated or corrupted firmware can also cause a range of issues, including a buzzing noise. If your TV’s firmware is not up to date, it may be causing the noise.
Hardware Failure
In some cases, the buzzing noise could be a sign of hardware failure. This could be related to the TV’s internal components, such as the T-Con board or the main board.
Troubleshooting Steps To Stop The Buzzing Noise
Now that we’ve identified the possible causes, let’s dive into the troubleshooting steps to help you stop the buzzing noise on your LG TV.
Step 1: Check The Connections
As mentioned earlier, loose connections can cause a buzzing noise. Check all the cables connected to your TV, including HDMI cables, power cord, and any other cables. Make sure they’re securely plugged in and not loose.
Step 2: Move Devices Away From The TV
Electrical interference from other devices can cause a buzzing noise. Try moving devices with motors, such as refrigerators or air conditioners, away from your TV. This can help reduce the electrical interference and eliminate the buzzing noise.
Step 3: Update The Firmware
Outdated firmware can cause a range of issues, including a buzzing noise. Check if there are any firmware updates available for your LG TV. To do this, go to the TV’s menu, select “Settings,” then “Support,” and finally “Software Update.” If an update is available, follow the on-screen instructions to download and install it.
Step 4: Check The Power Supply
If the power supply unit (PSU) in your LG TV is malfunctioning, it may cause a buzzing noise. Check if the PSU is working properly by trying a different power outlet or replacing the PSU if necessary.
Step 5: Reset The TV
In some cases, a simple reset can resolve the issue. To reset your LG TV, go to the TV’s menu, select “Settings,” then “Support,” and finally “Factory Settings.” This will reset the TV to its factory settings, which may resolve the buzzing noise issue.
Advanced Troubleshooting Steps
If the above steps don’t resolve the issue, it’s time to move on to some advanced troubleshooting steps.
Step 6: Check The T-Con Board
The T-Con board is a critical component in your LG TV’s display system. If it’s malfunctioning, it can cause a range of issues, including a buzzing noise. Check if the T-Con board is working properly by looking for signs of physical damage or overheating.
Step 7: Check The Main Board
The main board is the brain of your LG TV, responsible for controlling all its functions. If it’s malfunctioning, it can cause a range of issues, including a buzzing noise. Check if the main board is working properly by looking for signs of physical damage or overheating.
Step 8: Contact A Professional
If none of the above steps resolve the issue, it may be time to contact a professional TV repair technician. They can diagnose the problem and perform the necessary repairs to eliminate the buzzing noise.

Why Is My LG TV Making An Annoying Humming Noise?
The humming noise from your LG TV can be caused by a variety of factors, including loose connections, improper installation, or issues with the TV’s internal components. It’s also possible that the hum is coming from the TV’s power supply or other external devices connected to it.
To troubleshoot the issue, try to identify the source of the hum by turning off and on different devices connected to the TV. If the hum persists, try adjusting the TV’s settings or consulting the user manual for guidance. If the problem persists, it may be worth contacting a professional TV repair technician to diagnose and fix the issue.
Is The Humming Noise From My LG TV Normal?
The humming noise from your LG TV is not normal and indicates that there is an issue that needs to be addressed. While it’s true that some TVs may produce a slight humming or buzzing sound when they’re turned on, a loud and persistent hum is usually a sign of a problem.
If you’re concerned about the hum, it’s a good idea to investigate the cause and take steps to fix it. Ignoring the problem could lead to further damage to your TV or other connected devices. Additionally, a persistent hum can be distracting and disrupt your viewing experience, so it’s worth taking the time to troubleshoot and fix the issue.
Will Turning Off The TV’s Dolby Atmos Feature Silence The Hum?
Turning off the Dolby Atmos feature on your LG TV may help reduce or eliminate the humming noise, especially if the feature is not being used. Dolby Atmos is a surround sound technology that can sometimes cause the TV’s speakers to produce a humming or buzzing noise.
However, turning off Dolby Atmos may not completely eliminate the hum, especially if it’s being caused by a hardware issue or other factor. Additionally, turning off Dolby Atmos may affect the overall audio quality of your TV, so you may want to experiment with different settings to find a balance between sound quality and hum reduction.
Can I Use A Soundbar To Eliminate The Hum From My LG TV?
Using a soundbar can help mask the humming noise from your LG TV, especially if the soundbar is connected to the TV via an optical or HDMI connection. However, the hum may still be audible, especially if it’s coming from the TV’s internal components.
Keep in mind that a soundbar is not a permanent solution to the hum problem, and it may not completely eliminate the noise. If you’re concerned about the hum, it’s still worth investigating the cause and taking steps to fix it. A soundbar can be a useful addition to your home theater setup, but it’s not a substitute for properly diagnosing and fixing the issue.
Will Resetting My LG TV To Its Factory Settings Silence The Hum?
Resetting your LG TV to its factory settings may help eliminate the humming noise, especially if the issue is related to a software or settings problem. However, this should be done as a last resort, as it will erase all of your saved settings and preferences.
Before resetting your TV, try troubleshooting the issue and adjusting the TV’s settings to see if that resolves the problem. If you do decide to reset the TV, be sure to write down your settings and preferences beforehand so that you can easily restore them after the reset.
Can I Silence The Hum By Adjusting The TV’s Picture Settings?
Adjusting the TV’s picture settings may help reduce or eliminate the humming noise, especially if the issue is related to the TV’s backlight or panel. Try adjusting the TV’s backlight setting or switching to a different picture mode to see if that helps.
However, the hum may still persist, especially if it’s coming from a hardware issue or other factor. If adjusting the picture settings doesn’t work, you may want to try other troubleshooting steps or consult a professional TV repair technician for further assistance.
Is It Safe To Use My LG TV Even If It’s Making A Humming Noise?
It’s generally safe to use your LG TV even if it’s making a humming noise, as long as the noise is not accompanied by other signs of malfunction, such as smoke, sparks, or a burning smell. However, the humming noise can still be a sign of a underlying issue that needs to be addressed to prevent further damage to the TV or other connected devices.
If the hum is loud and persistent, it’s worth taking steps to fix it to prevent any potential harm to your TV or other devices. Additionally, if you’re concerned about the hum, it’s always a good idea to consult the TV’s user manual or contact a professional TV repair technician for guidance.
