LG TV Flickering

LG TVs have a knack for starting to flicker after using them for some time. This can completely ruin your viewing experience, especially if you’re one who likes to come home and relax watching your favorite show on TV without any interference. While it’s scary to see your newly bought LG TV start acting up like this, there are a number of ways you can use to fix the issue.

The leading causes behind a flickering LG TV are faulty streaming service, weak internet connectivity, and corrupt external devices. However, you can eliminate this issue by disabling the energy-saving mode, adjusting the backlight, and using a power surge protector.

Fixing a TV can be complicated, and even a minute mistake can create problems that might be pretty expensive to repair. However, if you know what’s really causing the flickering issue, repairing it can often become a piece of cake.

Major Causes Of A Flickering LG TV

The first step is to determine the cause of your LG TV flickering so that you can implement the most suitable remedy. Here are the three most common reasons for a flickering TV:

Cause 1: Faulty Streaming Service

If you are using a streaming service on your LG TV, a glitch in that streaming app can cause your LG TV to flicker.

Consider using a different device to sign up for the same streaming service. If the issue still exists on the new device, it means the streaming service app is buggy and your LG TV is absolutely fine.

This issue is out of your control so to fix this, you can only submit your complaints to the customer support team of the streaming service at the appropriate link.

Cause 2: Poor Internet Connectivity

Poor internet connection is one of the prevalent causes of a flickering TV. You should keep your internet router within 30 feet of your TV to avoid connectivity issues and provide your TV with better signals. However, you should also not keep the router too close to the TV. If the router is just within five to six feet of the TV, the TV’s screen may pause.

Furthermore, there can also be a glitch or a bug in the router that is causing your LG TV to flicker.

How To Check For A Bug In Your Internet Router

As mentioned, a bug in your internet router can cause the TV screen to flicker. You can follow these simple steps to determine whether this is the issue or not:

Step 1: Turn off your router by disconnecting it from the power socket.

Step 2: Wait for 15 seconds.

Step 3: Switch on the router and check your internet connection. If the issue is fixed, it was a bug causing your LG TV to flicker.

Cause 4: Corrupt External Sources

Sometimes, the devices you have linked to your TV can cause it to malfunction and flicker. This happens if the external sources are corrupted or faulty, causing your TV to get glitchy and flicker.

How To Check If External Device Is Faulty

Try doing a picture test on your TV to see if the linked gadgets are the issue. The following procedure will determine whether your external devices are causing the flickering:

Step 1: Select the SMART button on your TV remote.

Step 2: Go to Settings and then click on Support.

Step 3: Choose Picture Test, and then WHEEL or Enter.

Step 4: Conduct the Picture Test by following the on-screen directions.

Step 5: If the test fails, proceed as directed on the screen to the next steps.

Step 6: Disconnect any external devices linked to your TV if the test is successful.

If everything appears in order on your image test, that is excellent news for your TV but terrible news for whatever external device you have connected. Your pc, game console, or cable box is causing the problem.

Other Solutions For LG TV Flickering

If you’ve tried the above remedies to no avail, here are 3 solutions recommended by the community that can help you stop your LG TV from flickering:

Solution 1: Disable Energy-Saving Mode

Energy-saving mode allows you to save power by turning off the TV when it is not in use. Although the energy-saving mode is a helpful way to save electricity, it can also cause visual issues on the screen, like the screen flickering.

How To Disable Energy-Saving Mode On Your LG TV

You can follow the steps stated below to disable the energy-saving mode on your LG TV and stop it from flickering:

Step 1: Click on the SMART button on your remote.

Step 2: Select Settings, then Picture.

Step 3: Go to the Energy Saving option and deactivate it if it is set to AUTO.

Step 4: Turn off your TV and then switch it on. In many cases, this will be enough to eradicate flickering.

Solution 2: Change the Backlight Settings

Keep in mind that increasing the lighting intensity reduces the life of your LG TV. High-lighting settings can also harm your TV’s hardware.

Moreover, a strong backlight can cause multiple colors to flash on your TV, making it flicker. Hence, try adjusting the brightness of the TV’s backlights to avoid similar problems.

How To Change Backlight Settings On Your LG TV

Even though changing the backlight settings is easy, you should still follow these steps to avoid mistakes:

Step 1: Click on the Settings button on your LG TV’s remote.

Step 2: Select All Settings from the menu.

Step 3: Go to the Picture menu and select Picture Mode Settings.

Step 4: Click on Customize, and then choose Backlight.

Step 5: Modify the setting if it is set to 100 and reduce the lighting intensity until your TV stops flashing.

Solution 3: Use A Power Surge Protector

An external device connected to the TV might produce electrical interference, causing the power circuit to be disrupted. This will cause the TV to flicker. Furthermore, instability in the current flow can also cause your LG TV to flicker.

I recommend purchasing a good power surge protector like Belkin to filter out high or low power during spikes. Even though a power surge protector is typically included with an LG TV, you will need to change it if it becomes damaged.

You will need to call a technician to get the power surge protector installed.
