LG Smart TV Black Screen of Death Problem, How to Fix?

Now that we have a good understanding of what might be triggering the black screen of death problem, it’s time to apply the solutions to get them fixed.

Solution 1: Check the Cables

The cable should be connected properly to take the smart TV’s full leverage. Not doing this can be an invitation to many problems. Inspect every cable carefully and make sure that none of them are damaged. Also, make sure that the HDMI cable is connected properly.

A loose HDMI cable can result in screen flickering, black screen, and more. Hence, it’s a must to properly connect the HDMI cable. You also need to take care of the sound and video cables. Ensure they are connected to the correct ports and are not loose. Remove any cables if you are unsure about them and plug them in again. Now, turn on the TV and check whether the issue is fixed.

If your LG smart TV still shows a black screen, plug the HDMI cable into another HDMI slot (if there’s any). We also need to make sure that the HDMI cable is not defective from the inside. For this, you’ll need a new HDMI cable. Connect the new one to the TV and check if the problem is fixed.

If the black screen on your LG smart TV is caused by a software bug or a system glitch, this method can do the trick for you.

Here’s how to perform a power cycle on your LG TV:

1. Unplug the power cable from the wall socket.
2. Keep it unplugged for 5 minutes.
3. Plug the power cable back into the wall socket.
4. Turn on the TV and check if the issue persists.

Solution 3: Change Picture Mode and Backlight Settings
