TV flickering can be a frustrating issue for many viewers. It can occur for various reasons, including improper HDMI connections, cable signal issues, or energy-saving modes.

Fixing TV flickering is important as it can not only enhance the viewing experience but also prolong the life of the TV. In this article, I will provide steps to fix flickering on an LG TV.

How To Fix LG TV Flickering?

Check HDMI Connections

One of the most common causes of TV flickering is improper HDMI connections. To ensure proper connections, follow these steps:

  • Check the HDMI cables connecting the TV to other devices, such as a cable box, Blu-Ray player, or gaming console.
  • Ensure the cables are securely inserted into the TV and other devices and are not loose.
  • Try using a different HDMI cable to see if that resolves the issue.

It’s important to have proper HDMI connections to avoid TV flickerings and other potential issues, such as poor picture quality or no picture. If you have checked the HDMI connections and the TV is still flickering, move on to the next step.

Power Cycle the TV

Another simple step to fix TV flickering is to power cycle the TV. Here’s how to do it:

  1. Turn off the TV and unplug it from the wall outlet.
  2. Wait for 30 seconds.
  3. Plug the TV back in and turn it on.

Power cycling the TV can help resolve minor software glitches or temporary technical issues and be a quick and easy solution for TV flickering. If the flickering persists after power cycling the TV, move on to the next step.

Check Cable Signal

Another possible cause of TV flickering is a weak or unstable cable signal. To check the cable signal, follow these steps:

  1. Disconnect the cable from the TV and check for any visible damage, such as kinks or frays.
  2. Try connecting a different cable or device to the TV to see if the flicker persists.
  3. Check the cable signal strength on the TV or through the cable provider’s equipment.

A weak or unstable cable signal can cause TV flickering, and checking the cable signal can help determine if this is the issue. If the cable signal is fine and the flickering persists, move on to the next step.

Disable Energy-Saving Mode

Energy-saving mode on a TV can also cause flickering. To disable energy-saving mode, follow these steps:

  1. Go to the TV’s Settings.
  2. Go to Settings > All Settings > Support > Energy Saving.
  3. Set Energy Saving to Off.

Energy-saving mode is designed to reduce the power consumption of the TV, but it can also cause flickering. Disabling the energy-saving mode may resolve the issue. If the flickering persists after disabling the energy-saving mode, move on to the next step.

Update TV Firmware

Outdated TV firmware can also cause flickering. To update the TV firmware, follow these steps:

  1. Go to the TV’s Settings.
  2. Go to General.
  3. Scroll down and select About this TV.
  4. Make sure that Automatic Updates is selected.
  5. Check for updates here to ensure you are always up-to-date with the latest version.

Updating the TV firmware can help resolve compatibility issues and fix any bugs causing the TV to flicker. If the flickering persists after updating the firmware, move on to the next step.

Factory Reset the TV

If the previous steps have not resolved the TV flickering, a factory reset may be necessary. A factory reset will erase all personal settings and restore the TV to its original factory settings.

To factory reset the TV, follow these steps:

  1. Go to the TV’s Settings.
  2. Go to General.
  3. Choose the “Reset to Initial Settings” option.

A factory reset should only be considered a last resort, as it will erase all personal settings and customizations. If the flickering persists after a factory reset, it may be time to seek professional assistance from LG Support.


TV flickering can be a frustrating issue, but it can often be resolved by following simple steps such as checking HDMI connections, power cycling the TV, checking cable signal, disabling energy-saving mode, updating TV firmware, and factory resetting the TV.

By following these steps, viewers can enhance their viewing experience and prolong the life of their LG TV. If these steps fail to improve the flickering, your best option may be to seek help from a professional at LG support.
