Why Did My LG TV’s Picture Suddenly Fade Out?

There is no exact reason for this.

It happens for a variety of reasons and the cause varies depending on how much the screen fades out.

Most of the time, if the picture fades out suddenly, without any input changes or settings changes, then the reasons are:

Backlight or T-Con Board Problems.

Panel failure.

If this is the case, you need to open the TV’s back panel, one by one check the T-con board, backlight, and panel.

Once you identify the culprit, you have to replace it.

No, the issue started after settings/input changes

Well, then reset the settings that you changed recently.

If you can’t recall what settings you made change, then you might want to reset the TV’s picture settings completely.

Or you can even go with a factory reset.

Basic troubleshooting steps

Whatever the reasons, you could try some basic troubleshooting things as a first step.

Ensure all cables (HDMI, etc.) are securely connected to your TV and any external devices.

Try different cables if possible.

After that, disconnect the TV from the power outlet, wait for a few minutes, and then plug the TV back in.

If none of the above methods work, then you could go with the process I discussed above.

I hope this helps.
