One issue many LG TV users have that is common is the screen going black on their TV after a couple years of use. Just like any other device these TV’s can develop issues after using them, but no worries because there are steps you can take to try and troubleshoot and resolve the issue. 

In this article, we’ll teach you those steps so you can rest easy knowing your TV hasn’t broken. Luckily, there are lots of fixes that are relatively quick and painless. 

Why Is My LG TV Screen Black?

There are many reasons your TV can turn black all of a sudden. Like many other technology devices after using them for a while, there are always issues that can arise. Luckily there are many of these issues that are straightforward and easy to determine and figure out what’s wrong. 

If your screen goes black on your LG TV you can unplug the TV from the wall for 60 seconds, plug it into a different outlet, and ensure good connection with the cables. If this still doesn’t work you can reset the TV by unplugging it from the wall again, pressing the power button for 30 seconds, then plugging it back into the wall. Once you’ve done this you can try to repower on the device as your TV has now reset. 

Remote Not Working

The result of a black screen can be an indicator that your LG TV has been turned off and your remote isn’t working when trying to turn it back on. To determine if it’s your remote, you can:

  • Power the TV on using the power button located on the TV. 
  • If possible, try to operate the TV using a different remote or your cell phone. 
  • If that solves the issue, it’s more than likely just the remote, but if it still doesn’t work it’s another problem. 

TV’s Firmware Issues

If you don’t have any issues with your remote, you can check the power indicator light on the front of your television. If the light is on, it could be a software issue causing the screen to be black. If you don’t turn your TV off as recommended, the TV software could cause technician issues. When this happens it causes the inability to install new updates on the TV and these issues can emerge with no warning. The good news is, you can fix this. 

TV’s Power Supply Board

There is a huge variety of power supply issues that can alter the functioning of your television screen. If your power supply board fails it can be a major problem. Some TV’s have multiple power supply boards. If just one of them fails it can still interfere with the ability for your screen to function and work properly. 

How To Fix Black Screen

There are many things you can try to fix your screen when it goes black. It can be inconvenient when your screen goes black or doesn’t work but there are multiple simple solutions you can try to get it up and working again. 

Remote Controller Issues

You can try the power button on your TV first. If your screen powers on then you have an easy fix to the problem. All you need to do is replace the batteries in your remote. If after replacing your remote batteries and the remote still isn’t working it may be time to purchase a new remote. You can find very affordable remotes. From many retailers, there are options such as this one

Unplugging LG TV

You can solve many LG TV software issues by doing a few simple steps. You can start by unplugging the TV from the wall for approximately 60 seconds. Then all you need to do is plug it back into the outlet and attempt to power on the TV again. If this doesn’t work then you may need to try a few more steps. 

It could be a possibility your outlet has gone bad so you may need to try and plug the TV into a different outlet in your wall. If this fixes the black screen issue then you may need to call an electrician to fix the power outlet in your home. 

Check The Backlight And Power Supply Board 

If your TV has an LCD screen, which most do, you should check this out to see if it’s the root of your problem. The backlight is what enables you to see images on your TV. If this stops working then your screen will go black and you won’t be able to see anything on your TV. To fix this issue, you should:

  • Shine a flashlight onto the TV screen
  • Look to see if you can still see the images on the TV even with the flashlight shining.
  • If you can see them with the flashlight, the LCD screen is broken and a new TV is needed. 

In Conclusion

There are several ways you can reset your LG TV even if it doesn’t have any pictures. You can simply turn off your TV and unplug it from the wall. Hold the power button for 30 seconds while leaving the TV unplugged. 

Then, plug it back into the outlet and turn it on. This should reset it and hopefully take care of the black screen you are experiencing. Hopefully, after trying the things suggested in this article your TV will be working properly and you will no longer be dealing with a black screen.
