Are you frustrated with your LG TV’s dimming screen? You’re not alone. Many LG TV owners have reported this issue, and it can be quite annoying, especially when you’re in the middle of a movie or a crucial sports game. In this article, we’ll delve into the possible reasons behind your LG TV’s dimming screen and provide you with some troubleshooting tips to resolve the issue.
Understanding the LG TV’s Dimming Feature
Before we dive into the possible causes, it’s essential to understand the LG TV’s dimming feature. LG TVs, like many other modern TVs, come equipped with a feature called “Dynamic Backlight Control” or “Local Dimming.” This feature adjusts the backlight’s brightness based on the content being displayed on the screen. The idea behind this feature is to improve the overall picture quality by reducing the backlight’s brightness in dark scenes and increasing it in bright scenes.
However, sometimes this feature can malfunction, causing the screen to dim unnecessarily. So, let’s explore the possible reasons behind your LG TV’s dimming screen.

What are the common reasons for an LG TV to dim?
An LG TV may dim due to various reasons, including incorrect picture settings, a faulty backlight, or a malfunctioning ambient light sensor. The ambient light sensor is designed to adjust the screen brightness based on the surrounding light, but sometimes it can cause the screen to dim unnecessarily. Additionally, a software glitch or a hardware issue can also cause the TV to dim.
To resolve the issue, it’s essential to identify the root cause of the problem. Start by checking the picture settings and adjust them to your preference. If the issue persists, try disabling the ambient light sensor or updating the TV’s software. If none of these solutions work, it may be a hardware issue, and you may need to contact an LG authorized service center for further assistance.
How do I reset my LG TV to its default settings?
Resetting your LG TV to its default settings can resolve many issues, including dimming. To reset your LG TV, go to the Settings menu and select the “Picture” or “Display” option. Look for the “Reset Picture Settings” or “Reset Display Settings” option and select it. Confirm that you want to reset the settings to their default values. This will restore the TV’s picture settings to their original values.
Keep in mind that resetting the TV will also reset all your customized picture settings, so you may need to adjust them again after the reset. Additionally, if you have any customized settings for other features, such as sound or network settings, they will not be affected by the picture settings reset.
What is the ambient light sensor, and how does it affect my LG TV’s brightness?
The ambient light sensor is a feature in LG TVs that adjusts the screen brightness based on the surrounding light. It uses a sensor to detect the amount of light in the room and adjusts the screen brightness accordingly. The idea behind this feature is to provide a more comfortable viewing experience by reducing eye strain.
However, sometimes the ambient light sensor can cause the screen to dim unnecessarily, especially if the room is not well-lit. If you find that your LG TV is dimming too much, you can try disabling the ambient light sensor. To do this, go to the Settings menu and select the “Picture” or “Display” option. Look for the “Ambient Light Sensor” or “Eco Sensor” option and toggle it off.
Can a software update resolve the dimming issue on my LG TV?
Yes, a software update can resolve the dimming issue on your LG TV. LG regularly releases software updates to fix bugs and improve the performance of their TVs. If the dimming issue is caused by a software glitch, updating the TV’s software may resolve the problem.
To update your LG TV’s software, go to the Settings menu and select the “Support” or “System” option. Look for the “Software Update” or “Firmware Update” option and select it. The TV will then check for any available updates and prompt you to download and install them. Make sure to follow the on-screen instructions carefully to complete the update process.
What are the signs of a faulty backlight on my LG TV?

If you suspect that your LG TV’s backlight is faulty, it’s essential to contact an LG authorized service center for further assistance. A faulty backlight can be a complex issue to resolve, and it may require professional repair or replacement.
Can I adjust the backlight settings on my LG TV?

Look for the “Backlight” or “LED Local Dimming” option and adjust it to your preference. You can also try adjusting the “Brightness” or “Contrast” settings to see if it improves the screen’s brightness.
Keep in mind that adjusting the backlight settings can affect the overall picture quality, so it’s essential to find the right balance between brightness and picture quality. If you’re not sure about the optimal backlight settings for your LG TV, you can refer to the user manual or contact LG’s customer support for guidance.
