Are you tired of constantly adjusting the brightness settings on your LG TV, only to have the screen fade to darkness minutes later? You’re not alone. Many LG TV owners have reported experiencing issues with their screens suddenly becoming dark or dim, leaving them frustrated and confused.
Understanding The Reasons Behind The Darkness
Before we dive into potential solutions, it’s essential to understand the reasons behind this issue. The causes of a dark or dim LG TV screen can be attributed to various factors, including hardware problems, software glitches, and settings misconfigurations.
Hardware-Related Issues
One of the primary reasons behind a dark or dim LG TV screen is a hardware problem. The backlight, which is responsible for illuminating the LCD panel, might be malfunctioning or failing. This can be due to various reasons, such as:
- Aging or worn-out backlight: Over time, the backlight can deteriorate, leading to a decrease in brightness and an increase in darkness.
- Loose or faulty connections: If the connections between the backlight and the LCD panel are loose or faulty, it can cause the screen to become dark or dim.

Checking for Hardware Issues
To determine if the issue is hardware-related, try the following steps:
- Check the backlight for any signs of wear or damage.
- Verify that all connections are secure and not loose.
- If you have a spare backlight or LCD panel, try swapping them to see if the issue persists.

Software issues can also cause an LG TV screen to become dark or dim. Some common culprits include:
- Firmware issues: Outdated or corrupted firmware can cause display problems, including darkness or dimness.
- Software glitches: Temporary software glitches can cause the screen to become dark or dim.
Updating Firmware and Resolving Software Issues
To resolve software-related issues, follow these steps:
- Check for firmware updates on the LG website and follow the instructions to download and install the latest version.
- Restart the TV and check if the issue persists.
- If the issue is still present, try resetting the TV to its factory settings.
Settings-Related Issues
Settings misconfigurations can also cause an LG TV screen to become dark or dim. Some common settings-related issues include:
- Incorrect picture mode: The picture mode might be set to a mode that reduces brightness or causes the screen to become dark.
- Backlight settings: If the backlight settings are too low, it can cause the screen to become dark or dim.
Adjusting Picture Mode And Backlight Settings
To adjust the picture mode and backlight settings, follow these steps:
- Press the “Settings” button on the remote control.
- Navigate to the “Picture” menu and select the desired picture mode (e.g., “Vivid” or “Standard”).
- Adjust the backlight settings by navigating to the “Backlight” or “Brightness” menu and increasing the level to the desired setting.
Other Potential Causes
Other potential causes of a dark or dim LG TV screen include:
- Cable or satellite signal issues: Weak or poor signal quality can cause the screen to become dark or dim.

What Is The Darkness Issue On LG TVs?
The LG TV darkness issue refers to a problem where the screen displays flickering or unresponsive to light. This issue has been reported by some users of certain LG TV models, particularly those with OLED panels. The issue can manifest in different ways, including an “OLED float” where the screen appears to “float” with a faint glow when it is supposed to be completely dark.
In some cases, the issue can also cause the image on the screen to be somewhat washed out or lacking in contrast. This can make it difficult for viewers to see the image clearly, especially in bright lighting conditions. The issue is often most noticeable when the TV is displaying dark or near-dark scenes.
Is The LG TV Darkness Issue Limited To OLED Panels?
The LG TV darkness issue is not exclusive to OLED panels, but it is more prevalent in these models. This is because OLED panels use a different type of backlighting than traditional LCD panels. Whereas LCDs use a single backlight, OLED panels have individual pixels that can be turned on and off to create true blacks. While this allows for better contrast and color accuracy, it also makes the panels more susceptible to flickering.
In addition to OLED panels, some users have reported experiencing similar issues with LG’s IPS and NanoCell panels. However, these issues are relatively rare compared to OLED panels. Regardless of the type of panel, the LG TV darkness issue can be frustrating for users, as it can detract from the overall viewing experience.
What Causes The LG TV Darkness Issue?
The cause of the LG TV darkness issue is often attributed to a combination of hardware and software factors. One possible cause is the ABL, or Automatic Brightness Limiter, which is designed to prevent the picture from becoming too bright. However, in some cases, the ABL can become overactive and start to dim the picture unnecessarily, leading to a “flickering” effect.
Another possible cause is a software issue with the TV’s picture processing. Some LG TVs use a feature called “Local Dimming,” which involves adjusting the brightness of different regions of the screen to create deeper blacks. However, if the software becomes confused or gets stuck, it can lead to the TV displaying a black or near-black screen even when it is not supposed to.
How Do I Troubleshoot The LG TV Darkness Issue?
If you are experiencing the LG TV darkness issue, there are several steps you can take to troubleshoot the problem. First, try adjusting the TV’s picture settings to see if you can improve the image quality. Check the Brightness, Contrast, and Local Dimming settings to ensure they are not set too low.
You should also check the TV’s HDMI connections to ensure they are secure and working properly. Try using a different HDMI port or cable to see if it makes a difference. Additionally, update the TV’s software to the latest version and reset the picture settings to their default values.
Can I Repair Or Replace My LG TV If I Experience The Darkness Issue?
If the LG TV darkness issue is due to a hardware problem, it may be possible to repair or replace the TV. In some cases, the issue can be caused by a faulty backlight or display panel, which can be replaced by an authorized LG service center. However, in other cases, the issue may be due to a software problem, in which case a simple software update or reset may be all that is needed.
Before contacting an authorized service center or attempting any repairs, it is recommended to consult the TV’s user manual or contact LG customer support for assistance. If your TV is still under warranty, you may be able to have it repaired or replaced at no additional cost.
What Are Some Workarounds For The LG TV Darkness Issue?
If you are unable to repair or replace your LG TV, there are several workarounds that can help mitigate the effects of the darkness issue. One possible solution is to adjust the picture settings to use the TV’s “Game Mode,” which can help to improve the image quality and reduce the likelihood of flickering.
Another solution is to use an external sound system, which can help to take the focus away from the flickering image and create a more immersive viewing experience. Additionally, using a calibration disc or a picture calibration app can help to fine-tune the TV’s picture settings and optimize its performance.
Has LG Acknowledged And Addressed The Darkness Issue?
LG has acknowledged the darkness issue and has taken steps to address it. The company has released software updates for certain TV models that are designed to fix the issue and improve picture quality. In addition, LG has also offered a warranty extension program for affected TV models, which provides owners with a longer warranty period and free repairs for issues related to the darkness problem.
However, it is worth noting that not all LG TV models have been updated to fix the darkness issue, and some users have reported continuing problems with the issue even after updating their TV’s software. As such, it is recommended to continue to monitor the TV’s picture quality and report any ongoing issues to LG customer support.
