LG currently stands as the only producer of OLED TVs, though several other entities are setting up pilot plants, and it is expected that multiple will advance to commercial production.
In this article, I’ll explore potential reasons for this problem and will offer some advice on how to resolve it.
Reasons for LG TV Screen Appearing Dark
Understanding Contrast and Backlighting
Backlighting and insufficient contrast are two of the main causes of the dark appearance of an LG TV screen. The process of backlighting involves illuminating the TV screen’s pixels, which produces the visible image.
A dim or dark image may be the consequence of backlighting not working properly. On the other hand, contrast is the distinction between an image’s lightest and darkest portions. The image may appear dark and washed out if the contrast is too low.
Solution: You can change the LG TV’s illumination and contrast settings to resolve these problems.
Monitoring the Backlighting Settings
On the LG TV, you should first navigate to the Picture Settings menu to examine and modify the backlighting settings.
Solution: To boost the quantity of light the TV emits, you can change this setting’s Backlight option. The backlighting can be increased to brighten the image and enhance the viewing experience as a whole.
Make Changes in Contrast and Brightness Settings
You should also review the contrast and brightness settings if the backlighting settings are ineffective. How bright and clear the image looks on the screen can be influenced by these settings.
Solution: You should find the Brightness and Contrast options within the Picture Settings menu to change the contrast and brightness. The brightness of the image can be made brighter overall by boosting the brightness and contrast.

The LG TV’s Calibration
The brightness and overall image quality of an LG TV can be enhanced by calibrating it. TV calibration involves changing the brightness, contrast, and program as part of providing a more realistic and accurate image. It’s possible to employ calibration equipment like the Datacolor SpyderX or the X-Rite i1 Display Pro.
Solution: By installing the calibration tool on a laptop and launching the software, the TV can be calibrated. The calibration procedure involves tweaking the TV’s settings to produce the optimum picture quality, which in turn will enable you to get crystal-clear images. The accuracy of the colors, the contrast, and the overall brightness of the image can all be enhanced by calibrating the TV.
Examining the Power Source
An LG TV screen that’s excessively dark may also have a bad power supply. Inconsistent illumination or a lack of electricity to the display may be caused by a power supply problem.
Solution: You should inspect the power cable and connectors to make sure they’re safe and undamaged before looking for problems with the power source. The power supply might need to be replaced if it’s not operating properly. However, changing the power supply can be a time-consuming and expensive repair, so it would be preferable to call in a professional.
Wear and Age
The brightness of an LG TV screen can be impacted by age and wear, just like any other electronic item. The TV’s backlighting may deteriorate or burn out with time, producing a dull or dark image. This is especially true if the TV is used regularly or is left on for a long time.
Did You Know LG TVs are the first in the world to have built-in voice assistants like Alexa?
Solution: Turning off the TV when not in use and avoiding leaving it on for longer than necessary are the best ways for you to keep away from this problem. You should also spend money on a top-notch voltage regulator, which can assist in shielding the TV parts from harm.
Here’s a list of some more causes of LG’s TV screens appearing dark and their possible solution:
| Cause | Solution |
| Incorrect Picture Settings | Adjust settings |
| Energy Saving Mode | Disable it |
| Faulty Backlight | Replace or repair |
| Outdated Firmware | Update firmware |

A defective backlight, improper picture settings, or insufficient contrast are just a few potential causes of a dark LG TV screen. Checking the TV’s settings and, if necessary, doing a factory reset are the best ways to diagnose the problem.
What causes the LG TV backlight to fail?
An LG TV’s backlight can malfunction for several different causes. Some of the typical reasons for backlight failure are listed below:
- Age: The backlight of an LG TV can stop working as it gets older, just like any other electronic item. The backlight on an older TV may decrease or stop functioning altogether.
- Power surge: The backlight of an LG TV can be harmed by an unexpected power surge. Lightning strikes, power failures, and other electrical disturbances may be to blame for this.
- Physical harm: Physical harm may also cause the lighting to malfunction. For instance, the TV’s backlight may get damaged if it’s dropped or struck.
- Manufacturing flaws: On occasion, the backlight can possess a flaw in its construction that causes it to break before its time.
- Overheating: The backlight of a television might overheat and stop working if it’s not ventilated properly or if the surrounding temperature is too high.
- Burnout: Burnout can also cause the lighting to fail. This may occur if the TV is left on for a prolonged period or if the lighting is too bright.
