Why Does LG TV Keeps Making A Humming Noise?

It may sound tedious, but the flaws in the design and functioning of LG TV are minor and can be fixed easily. Here is a list of all the potential problems you might be facing.

- Go to “Settings”
- Click on the “Picture” tab.
- Go to “Picture Mode”
- Scroll down to the “Brightness” settings.

Make sure you check all the levels of brightness. Keep your television on “mute” as you change the settings. Once you reach the optimum brightness level and the humming noise stops, you have fixed your LG TV.
If it doesn’t work, your speakers might have a problem.
Loud Volume Settings Can Damage Speakers
If you are used to listening to your TV at a high volume, it might cause a humming sound in the speakers. Turn down the volume and listen for the humming noise. If the humming noise disappears, it means that you need to use a lower volume setting on your LG TV.
Faulty Speakers From Excessive Usage
If LG TV keeps making a humming noise, the noise stops as soon as you put it on mute. It means that there is a problem with the speakers. Call LG customer service and see if you can fix the problem on your own. If not, take your LG TV to the nearest service centre and fix it.
Repeated Overheating Damages Fans
The cooling fans in LG TV get damaged after some time. If you have overused your LG TV or placed it in a cramped corner, the fan would have to run overtime. If you can replace the fan on your own, then get a new one from an LG TV store. Therefore, you should take your TV to the nearest customer service centre and get the fan fixed.
Your TV Could Be Malfunctioning
If you have joust bought a brand new LG TV and it makes a humming noise, you might have a malfunctioning model. The LG TV LM620T range was diagnosed with a humming problem in 2012. If you were not aware of the situation, you need to replace your TV with another one.
Maybe your TV mounted close to the wall
When an LG TV is placed too close to the wall, it makes a humming noise. When LG TV becomes overheated because of poor ventilation, it produces humming noise. Make sure you have at least 10 centimetres between the wall and the back of the TV to allow proper air circulation. There are a few ways in which you can fix this problem.
- If your LG TV is mounted, you might need to fix the screws at the back. Loosen the screws a little to allow space between the wall and the LG TV.
- To create space, you can place the LG TV on a small table or shelf and move it a few inches away from the wall.
- Place the LG TV in a cool spot to ensure it doesn’t overheat.
- Amp up the air conditioning to keep the area cool.
Once you have maintained a proper distance between the wall and LG TV, turn it on to check whether the humming sound has stopped or not. If the problem isn’t resolved, try the next solution.
Damage to Audio ICs Lead to Distortion

If you have lowered your LG TV volume and still have the humming sound, try to fix it by troubleshooting your LG TV. Troubleshoot the audio to resolve the issue of the audio distortion.
