How to Fix LG TV Black Screen

When you are faced with a black screen on your LG TV, it can be a source of frustration. There are times when turning the TV off and then back on can quickly fix a random glitch, but other times this is not the case. 

Let’s look at the most frequent causes of a black screen and the best ways to rectify this issue.

Power Cycle Your LG TV

One of the fastest ways to put an end to a black screen on your LG TV is to power cycle the device: 

  • Step 1: Unplug the TV from the outlet
  • Step 2: Wait at least 10-15 minutes before turning it back on. 
  • Step 3: To turn the TV back on, hold the power button at the bottom of the TV for at least 10-15 seconds. 

If a temporary glitch causes the black screen, this remedy should fix the problem.

If the TV has sound, but no picture, turn the TV on using the button on the TV and not the remote. 

When the TV has turned on, use the button on the TV for Menu to see if this information appears on the screen. If it does not appear, your TV may need service. There are still a few more things to try before looking into a repair. 

Check If the Power Cables Are Plugged Into Your LG TV

Checking the connections for your power cables could resolve an issue with something being accidentally knocked out of place. 

Visit all the connected cables between your TV and other sources, such as cable boxes, VCR, or connected devices such as an Amazon Fire Stick. Also, make sure that your outlet is working properly and providing power to your TV.

Move the HDMI Cables Connected to Your LG TV

When all your power cords have been checked, moving any connected HDMI cables to another HDMI slot can be attempted to troubleshoot the input and ensure it is working properly. 

Check Your LG TV’s Connection Placements

When the TV has a connected component, checking to verify that the correct cables are connected in the proper sequence is essential. 

Ensuring that the red, blue, and green cables are connected in the correct order on both devices is essential. If you have made any changes, resetting the connection can be done by unplugging for a minimum of 30 seconds and plugging back in. 

Resetting an LG TV Back to Factory Settings

After trying all the above possible solutions and you still have a black screen showing, it might be time to complete a factory reset on the device. This process will erase any custom settings you have and require you to add them back in after the reset. This solution often works for a TV with a temporary glitch or an issue that can sometimes arise from backlight settings. 

Follow these steps to reset your LG TV back to its factory settings:

  • Step 1: Access settings and choose All Settings.
  • Step 2: Locate the General option and select it.
  • Step 3: At the bottom, you will see Reset to Initial Settings. Choose this.
  • Step 4: Your TV will complete the reset process.

Now if all of these issues don’t solve the problem, you should take a look at the next section.
