Resolving LG TV Flickering with Power Button Reset

A simple solution to the common issue of LG TV flickering is to unplug the TV from the wall and wait 60 seconds.

After unplugging the TV, hold down the power button on the TV itself for 30 seconds, not on the remote. This helps to drain any remaining power in the TV and allows it to reset properly.

Once the TV is plugged back in after the 60-second wait, it should power up with no further flickering.

Your LG TV has an Energy Saving mode

Disabling Energy Saving Mode on LG TV

Your LG TV has an Energy Saving mode that helps conserve power by adjusting various settings. However, this mode may cause problems sometimes. To turn off Energy Saving mode, follow these steps:

Go to Settings > All Settings > Support > Energy Saving
Turn Energy Saving OFF.

If you cannot find the Energy Saving mode option, try this alternative:

Press the Home/Start button on the remote
Select Settings
Select Picture
Select Energy Savings
Make sure it is set to OFF.

Diagnosing Picture Settings on Your LG TV

If you’re experiencing flickering on your LG TV, it’s possible that the issue is with your TV’s picture settings. A simple solution is to run a TV picture test. Here’s how:

Go to Settings > All Settings > Support > Screen Self-Diagnosis.
The test will guide you through the process and provide recommendations on how to adjust your settings to ensure your screen is working properly.

By running this test, you can get an idea of whether your picture settings are contributing to the flickering issue, and make necessary adjustments to fix it.

However, if the test does not resolve the problem, there may be other underlying issues that need to be addressed.

Verifying the Video Source for Flickering on LG TV

It’s possible that the cause of your LG TV flickering on and off could be due to the video source you’re using or the device connected to it. To check, try changing the input or video source that you’re using.

For example, flickering can occur if your TV receives corrupted frames from a streaming broadcast.

By testing with a different video source, you can determine if the issue is with your LG TV or with an external device such as a Firestick, Roku, or another streaming device. This step can also help you to identify if the problem lies with the cable connecting your TV to another device.

Check Connections for Damage or Looseness

Examine all the connections to your LG TV, including cords, wires, and cables, to see if they are bent, damaged, or have become loose.

If the flickering only occurs when using a specific input, it is a clue that the associated connections are the problem.

For instance, if the flicker occurs only while playing video games, inspect all the cords linked to the gaming console, particularly the HDMI cord as it is known to cause issues.

If disconnecting and reconnecting the cords doesn’t solve the problem, try using a different HDMI port or cable.

Similarly, if the flicker happens only while using cable TV, inspect the wires linked to the cable box. In the case of a damaged cord, replacing it won’t cost much.

Update the Software on Your LG TV

To ensure your LG TV is running smoothly, it’s important to keep its software updated.

To check for updates, go to the TV settings and navigate to All Settings > General > About this TV. Make sure the “Automatic updates” option is checked, and if not, manually update your TV software.

To update manually, find the relevant product support page, download and extract the software file, place it in a folder named “LG_DTV” on a USB drive, and then follow the instructions on the TV screen to complete the update. Regular software updates will help keep your LG TV functioning optimally.

LG Electronics continued to develop various electronic products, such as releasing the world’s first 84-inch ultra-HD TV for retail sale.

Reset LG TV to Factory Settings

If updating the TV’s operating system did not resolve the flickering problem, consider resetting the TV to its original factory settings. Here’s how:

Power on the TV.
Click the Gear icon on the remote control.
Go to All Settings (Advanced Settings) > General > Reset to Initial Settings.
The TV will turn off and then on again, and the initial setup screen will be displayed.

Before initiating a factory reset, make sure to back up any important data or settings, as they will be permanently deleted during the process.

Investigating Internal Hardware Problems

If the screen flickering issue on your LG TV persists after trying other troubleshooting options, it could be due to a problem with an electrical component inside the TV.

This type of problem is likely not to be fixable by a non-professional and taking the TV in for repair or considering a replacement is probably the best option.

If the TV is relatively new, it may still be covered under warranty, so it’s worth checking.

Checking LG TV Warranty

As a final effort, you can check if your LG TV is still covered under warranty.

If the issue is determined to be covered under warranty, LG may repair or replace the TV and even offer in-home services. Checking the warranty is definitely worth a shot.

The warranty is typically limited to the original purchaser and may not be transferable to subsequent owners.
