Why Is Your LG TV Making a Buzzing Noise?

Is your LG TV making a buzzing noise? That static sound can be pretty annoying!

This can happen for various reasons. It might be due to an issue with your backlight, speakers, fans, or a malfunction with your unit.

No worries, though!

You’ll be able to enjoy your favorite movies and shows in peace once again. In today’s post, we’ll help you locate the cause of this issue and fix it. Stick around.

Why Is an LG TV Making a Buzzing Noise?

LG TVs have high-quality standards. There are low chances that your unit might be faulty. So, the buzzing noise is probably happening due to a simple issue that you can fix on your own.

We’ve made you a list of the most common issues that might cause your LG TV to make a buzzing noise:

Damaged Speakers

The first thing you should check is the TV speakers. Most often, they’re the cause of this issue. 

Having your volume at a high level for long periods can damage the speakers. It might be a good idea to buy an external sound system if you appreciate really high volumes.

You can do a check by simply muting your TV. If the noise stops, it means that your speaker is causing this problem.

Lowering your volume might be the solution. If this doesn’t solve the problem, you can visit the nearest LG service center or contact LG customer service.

Additionally, if you’re using a soundbar or external speakers, make sure the cables are connected securely to your TV. A loose cable can cause buzzing or static noise.

Perform a Sound Test

You can also perform a sound test to see if one of the internal speakers is malfunctioning.

Here’s how:

  1. Press the ‘Menu’ button on your remote (it might be labeled “Smart” on some devices)
  2. Scroll to the ‘Settings’ tap
  3. Select ‘Sound Settings’
  4. Click on ‘Sound Test’
  5. Listen carefully to determine if there’s an issue with your speakers.

High Brightness Levels

Keeping the brightness at a high level for extended periods can be the cause of the buzzing and humming noise coming from your TV.

Keep the Screen Brightness Down

You can lower your TV’s brightness levels by following these steps:

  1. Press the ‘Menu/Smart’ button on your remote
  2. Click on the ‘Settings’ tap
  3. Select ‘Picture Settings’
  4. Scroll down to ‘Brightness Settings’
  5. Lower your brightness levels until the noise stops

It’s worth mentioning that you should mute your TV while lowering the brightness.

If the noise doesn’t stop after you lower the brightness level, you can eliminate it from your troubleshooting.

Cooling Fan Problems

Some LG TV models come with cooling fans installed in them. Those fans usually produce an undetectable level of humming.

If they’re becoming loud, that could be due to one of these reasons:

  • Your TV is overheating
  • Your TV is mounted too close to the wall
  • Fans are malfunctioning
  • Fans need cleaning or maintenance

Protect Your TV from Overheating

If your TV is overheating, you can turn it off for a while or until it cools down. This usually isn’t a common problem unless you live somewhere really hot and humid.

You can turn on an air conditioner or a fan and aim it towards your TV to minimize overheating. If that doesn’t fix the issue of loud fans, you should contact LG’s customer service or visit a service center to have your fans fixed.

Connectivity Issues

A loose or damaged cable can cause a static or buzzing noise. Try unplugging all unnecessary cables from your TV to check if they’re the cause of the problem.

If the noise stops, carefully plug back the cables one by one. If there’s a damaged cable, you’ll start hearing the noise again once you plug it back.

Check for Wireless Overlapping

Most of today’s devices come equipped with numerous wireless connections. These connections can overlap and cause a static or buzzing noise. 

Try turning off the Wi-Fi and Bluetooth connection. It sounds too good to be true, but the solution might be as simple as that!

Additionally, some devices can cause disruptions in the TV’s electronic components with their magnetic fields. So, remove any electronic devices placed near your TV to avoid this problem.

Contact LG’s Customer Service

LG provides great customer service and repair options. If you are unable to fix the issue after following the previous steps, it’s best if you contact LG customer service.

You can call them, email them, or even chat with them to find a suitable solution or schedule a repair.

Alternatively, you can just take your device to the nearest service center.
