LG Smart TV Screen Flickering, How to Fix Blinking on and off Issue? 

LG is one of the leading manufacturers of smart televisions, and their products offer a range of features and functions to suit the needs of any consumer. However, LG Smart TVs can sometimes experience issues like all electronic devices, such as screen flickering.

Flickering screens can be a real nuisance and can make watching TV an unpleasant experience. Fortunately, there are many ways to fix this problem and get your TV back to normal. In this article, we will go over some of the most common ways to get your LG Smart TV screen back to normal.

What Causes the Screen to Blink On and Off on LG Smart TV?

There could be several reasons why your LG Smart TV is flickering. Here are some of the most common reasons: 

1. A faulty power cord could be the cause of the flickering screen. If the cord is damaged, frayed, or otherwise compromised, then it could be causing the screen to flicker, and the TV may not receive the power it needs. 
2. If the power outlet is not providing the proper voltage or is not grounded properly, then it could be causing the TV to flicker. 
3. Poor connections between the TV and the other components in your home entertainment system. 
4. The flickering screen could also be due to the TV settings. 
5. Finally, the screen flickering could be related to outdated firmware. If the TV is running an old version of the firmware, then it may not display the picture properly.

Fix LG Smart TV Screen Flickering Issue

Now that you know the causes, it should be easier for you to troubleshoot this issue. Below are some fixes that will help you eliminate the flickering screen issue on your LG smart TV.

Fix 1: Restart your TV

The first step you should take is to restart your TV. This solves many common problems and could help to fix the flickering screen issue. To restart your TV, press the power button on the TV or the remote control and wait for the TV to power off. Once the TV has powered off, please wait a few seconds and then turn it back on. If the screen still flickers, try the next step.

Fix 2: Check the Power Cord

The next step is checking the power cord to ensure it is securely connected to the power outlet and the TV. Ensure the power cord is undamaged and the connection is tight. If the power cord is damaged, you will need to replace it.

Fix 3: Check all your Connections

You should check all the other connections if the power cord is fine. First, it is important to check all of your connections. Your HDMI or other cables may have become loose, causing the flickering. Make sure all of your connections are secure and that they are connected to the right ports.

Additionally, if you have connected your LG Smart TV to an external device like a laptop or game console, ensure that the device is turned on and the connection is secure. Also, make sure that the HDMI cables and other connections are undamaged. If any cables are damaged, you will need to replace them.

Fix 4: Check your Internet Connection

If your TV is connected to the internet, you should also ensure that your internet connection is working properly. To check your internet connection, try to access the internet on another device. If you can access the internet, then your connection is working properly.

Fix 5: Turn Off Energy Savings Setting

Some LG Smart TVs have an energy savings setting that can cause the screen to flicker. This setting can be easily adjusted in the TV’s settings menu. It is important to turn off this energy savings setting to prevent flickering from occurring.

To turn off the energy savings setting:

1. Open the LG Smart TV’s menu by pressing the Home/Start button on the remote control.
2. Then, navigate to the Settings menu and select Picture.
3. In the Picture menu, look for Energy Savings option and turn it off.
4. This will disable the energy savings setting, which should fix the flickering issue.

Fix 6: Hard Restart your TV

If none of the previous steps has worked, you should try to perform a hard restart of your TV. A hard restart involves unplugging your TV from the power supply and leaving it for a few minutes or an hour before plugging it back in. This can help reset the TV and may resolve any software-related issues causing the flickering.

To perform a hard restart of your LG Smart TV, follow these steps:

1. Unplug the power cord from your TV.
2. Leave the TV unplugged from the power source for at least 15-20 minutes. 
3. Plug the power cord back into the TV.
4. Turn on your TV and see if the flickering has been resolved.

Fix 7: Perform a TV Picture Test

If your LG Smart TV is still flickering, then you should perform a TV picture test. This test will help you identify the source of the problem and hopefully fix it. Here are the steps you need to take to run a TV picture test on your LG Smart TV:

1. Open the LG Smart TV’s menu by pressing the Home/Start button on the remote control.
2. Then, navigate to the Settings menu and select Support.
3. Select Picture Test.
4. You will now be asked a series of questions regarding the picture quality of your TV.
5. Once the test is complete, follow the on-screen instructions to fix the issue.

Fix 8: Update your LG TV Software

If none of the above steps has worked, then you should try to update the software on your LG Smart TV. Updating the software can help fix any bugs or glitches causing the flickering screen. To update the software on your LG Smart TV, follow the steps below:

1. On your remote control, press the Home/Start button.
