Read on to learn more about why this issue occurs and how you can fix it.

Causes Of Screen Dimming

It’s like a pesky shadow that won’t go away; your LG TV is constantly dimming. The causes of this annoyance can be complex, but often the clues to resolving it are right in front of you.

One possible cause is a setting on the TV itself, such as the brightness or picture mode settings.

If these settings are too low, then they can cause the TV to appear dimmer than normal.

Other power-related issues like faulty hardware and power surges can also cause dimming.

In some cases, a light sensor within the TV may think it’s getting too dark and will adjust accordingly, leading to an unnatural dimness.

These issues can range from simple fixes to more serious problems with the hardware of your LG TV. Knowing what could potentially be causing your issue will help you take the necessary steps to resolve it.

Troubleshooting Tips

If your LG TV keeps dimming, there are a few troubleshooting tips you can try before seeking professional assistance. To start, check the TV brightness settings and make sure they’re set according to your preference.

If that doesn’t help, here are some other potential solutions to explore:

  • Adjust the TV settings – Go into your LG TV’s settings menu and adjust any relevant options that could be causing this issue.
  • Check for software updates – Make sure your LG TV has the latest software installed so it can run optimally.
  • Try a factory reset – If all else fails, try a factory reset on the LG TV to get it back to its original state.

It’s important to keep in mind that some TVs have an auto-dimming feature designed to save energy and adjust brightness depending on the environment.

If this is the case with your LG TV, simply turn off this option in order to prevent future dimming issues.

With these troubleshooting tips in mind, you should now be better equipped to tackle any dimming issues with your LG TV! With these steps completed, it may be time for professional assistance if none of these solutions solve the problem.

After troubleshooting tips have been explored, the next step is to consider professional assistance. If your LG TV keeps dimming and you’ve exhausted all your options, it might be time to call in a professional TV repair service technician.

A certified TV technician can diagnose the issue and provide a solution for your LG television service needs.

When selecting a tv repair specialist, make sure they are knowledgeable about repairing LG TVs and can provide an estimate of parts and labor costs up front.

It’s important to find someone who is reliable, has expertise with LG TVs, and puts customer satisfaction first.

If your tv isn’t functioning correctly after troubleshooting at home, contact a local professional or an authorized LG repair center for assistance. They will be able to quickly identify the problem and offer solutions that best fit your needs.

Preventative Measures

Preventative measures can help prevent your LG TV from dimming.

You can adjust the brightness or dim settings in the TV settings, allowing you to control how bright or dim you want your screen to be.

This way, you won’t have to worry about adjusting the brightness every time you turn on your TV.

Additionally, some TVs offer a ‘night mode’ setting that helps reduce eye-strain and prevents the TV from becoming too bright.

By making use of these features, you can keep your LG TV from dimming and ensure that it is comfortable to watch.

Furthermore, another preventative measure is to get an adjustable light-dimmer switch for the room where your LG TV is located. The switch will allow you to manage the amount of light in the room and prevent it from becoming too bright for comfortable viewing.

Lastly, if all else fails and your LG TV keeps dimming, consider replacing any old components that may be causing it such as cables or power supplies. Taking these steps will help ensure that you always have a pleasant viewing experience with your LG TV.


In conclusion, dimming on an LG TV can be a frustrating issue, like a stubborn knot that won’t come undone.

It happens for many reasons and can be difficult to troubleshoot.

Thankfully, there are ways to prevent it from happening in the first place.

If you’ve been unable to resolve your dimming issues with the tips outlined in this article, then it might be time to seek professional assistance.

They will be able to look at your TV and determine what is causing the dimming and provide individualized advice on how best to address the issue.

Overall, dimming of an LG TV can be a challenging problem, but with proper troubleshooting and preventative measures, I’m confident that you’ll find yourself back in control of your viewing experience soon enough.
