How to Fix a LG TV that is Showing a Black Screen

Why does my LG TV have a black screen?

The main reason why your LG TV is displaying a black screen is because of corrupt or outdated firmware, a faulty HDMI connection, or the backlight setting is too high.


We see our television as a dependable technology that operates on-demand to meet our usual entertainment demands.

We may occasionally get set to watch our favorite show only to be greeted by a dark screen. While this might be irritating, studying the problem and determining what caused it will quickly restore the entertainment.

Several factors can cause a black screen on your LG TV. Most difficulties may be resolved by updating firmware, providing power to the TV, and verifying connections are properly plugged in. Power cycling the TV or briefly disconnecting it usually fixes a black screen, resetting the TV functionality.

This problem can be caused by a variety of factors, including the image mode you have selected, a transient bug that has resulted in the black screen, repairing an overheated backlight, and others.


Possible causes:

  • Power Cycle
  • Backlight issue
  • Power source
  • Faulty connections


How do I fix a Sony TV black screen?

To fix a Sony TV black screen, you can unplug your TV, solve the problems with the remote controller or examine the backlight and power supply unit.

When your screen goes dark or stops operating, it might be inconvenient, but there are several easy options you can attempt to get it back up and running.


Problems with the Remote Controller

You may start by pressing the power button on your television. If your screen turns on, you have a simple solution to the problem.

You only need to change the batteries in your remote. If your remote still does not function after changing the batteries, it may be time to buy a new remote. Remote controls are relatively inexpensive. Options like this one are available from a variety of merchants.


Unplugging Your LG TV

Some LG TV software difficulties may be resolved with a few easy actions. Begin by disconnecting the television from the wall for approximately 45 seconds. All you have to do now is plug it back into the socket and try to turn on the TV again. If this fails, you may need to attempt a few more steps.

Your outlet may have failed, so try plugging the TV into a different outlet in your wall. If this resolves the black screen problem, you may need to contact an electrician to repair the electrical outlet in your home.


Examine the Backlight and the Power Supply Board

Whether your TV has an LCD screen, which most do, you should investigate to determine if this is the source of your issue. The backlight on your television is what allows you to view images. If this fails, your screen will go black, and you will be unable to see anything on your TV. To resolve this issue, you should:

  • Use a flashlight to illuminate the television screen
  • Examine the TV to check whether you can still see the graphics even with the spotlight on
  • If you can see them with a flashlight, the LCD screen is damaged, and you’ll need to buy a new TV


Alter the Picture Mode and Backlighting Settings

If you can obtain a picture after trying the fixes above, altering the image mode and backlight settings on your LG TV may help you resolve the black screen of death issue. It would help if you made the following adjustments to your image and lighting settings.

  • Select all options from the settings menu
  • Now, choose the image from the list

These modifications will keep your smart tv backlight from overheating, and you will no longer have an LG tv black screen issue on your LG smart TV.
