Burn-in, also known as image retention, is a common issue that can affect LCD TVs, causing permanent ghostly images to appear on the screen. This problem can be frustrating, especially if you’ve invested in a high-quality TV. Fortunately, there are ways to fix burn-in on LCD TVs, and in this article, we’ll explore the causes, symptoms, and solutions to help you revive your screen.
Understanding Burn-In on LCD TVs
Before we dive into the solutions, it’s essential to understand what causes burn-in on LCD TVs. Burn-in occurs when a static image is displayed on the screen for an extended period, causing the pixels to become fatigued. This can happen when you display the same image, such as a video game menu or a TV channel logo, for several hours or days.
LCD TVs use a layer of liquid crystals to block or allow light to pass through a matrix of pixels. When a static image is displayed, the liquid crystals can become stuck in a particular position, causing the pixels to retain the image even after the TV is turned off. This can lead to a permanent ghostly image on the screen.
Symptoms of Burn-In on LCD TVs
If you suspect that your LCD TV has burn-in, look out for the following symptoms:
- A faint, ghostly image of a static picture or logo appears on the screen
- The image is usually lighter or darker than the surrounding area
- The image is permanent and doesn’t disappear even after the TV is turned off
- The image can be more noticeable in bright or dark environments
Prevention is the Best Solution
Preventing burn-in is always better than trying to fix it. Here are some tips to help you prevent burn-in on your LCD TV:
- Avoid displaying static images for extended periods. If you need to display a static image, such as a video game menu, try to limit the time to less than an hour.
- Use a screensaver. Many modern TVs come with built-in screensavers that can help prevent burn-in. You can also set your TV to turn off after a certain period of inactivity.
- Adjust the TV’s picture settings. Lowering the brightness and contrast can help reduce the risk of burn-in.
- Use a TV with burn-in prevention features. Some modern TVs come with features such as pixel shifting, which can help prevent burn-in.
Fixing Burn-In on LCD TVs
If you’ve already noticed burn-in on your LCD TV, don’t worry. There are several methods you can try to fix it. Here are a few:
- Image retention compensation. Some TVs come with a built-in image retention compensation feature that can help fix burn-in. Check your TV’s manual to see if this feature is available.
- Pixel shifting. Pixel shifting involves slightly moving the image on the screen to help redistribute the pixels. This can help fix burn-in and prevent it from happening again.
- Screen calibration. Calibrating your TV’s screen can help fix burn-in by adjusting the brightness and contrast settings.
Using a Burn-In Fixing App
There are several apps available that can help fix burn-in on LCD TVs. These apps work by displaying a series of images that can help redistribute the pixels and fix the burn-in. Some popular burn-in fixing apps include:
- Burn-in Fixer (available on Android and iOS)
- Image Retention Fixer (available on Android and iOS)
- Pixel Fixer (available on Android and iOS)
DIY Methods to Fix Burn-In
If you’re not comfortable using a burn-in fixing app, you can try some DIY methods to fix burn-in on your LCD TV. Here are a few:
- Display a white screen. Displaying a white screen for an extended period can help fix burn-in by redistributing the pixels. You can display a white screen by playing a white video or by using a white screensaver.
- Display a moving image. Displaying a moving image, such as a video or a slideshow, can help fix burn-in by keeping the pixels moving.
- Use a burn-in fixing DVD. There are several DVDs available that can help fix burn-in on LCD TVs. These DVDs display a series of images that can help redistribute the pixels and fix the burn-in.

What is burn-in on LCD TVs and how does it occur?
Burn-in on LCD TVs is a permanent ghostly impression that remains on the screen after displaying the same image for an extended period. This phenomenon occurs when the same image is displayed on the screen for a long time, causing the pixels to degrade and lose their ability to display the correct colors. As a result, a ghostly impression of the image remains on the screen even after the image has changed.
Burn-in can occur due to various reasons such as displaying the same image for an extended period, using the TV as a computer monitor, or playing video games for long hours. It can also occur due to the TV’s settings, such as having the brightness and contrast set too high. To prevent burn-in, it is essential to take regular breaks and adjust the TV’s settings to a comfortable level.
How do I identify burn-in on my LCD TV?
Identifying burn-in on an LCD TV can be a bit challenging, but there are some signs that you can look out for. One of the most common signs of burn-in is a ghostly impression of an image that remains on the screen even after the image has changed. This impression can be a faint outline of a logo, a menu, or a static image. Another sign of burn-in is a discoloration of the screen, where certain areas appear brighter or darker than others.
If you suspect that your TV has burn-in, try displaying a full-screen image with a solid color, such as white or black. If you notice any ghostly impressions or discoloration, it could be a sign of burn-in. You can also try adjusting the TV’s settings, such as the brightness and contrast, to see if it makes any difference.
Can burn-in be fixed, or is it permanent?
Burn-in can be fixed, but it depends on the severity of the damage. If the burn-in is minor, it can be fixed by adjusting the TV’s settings or using a burn-in removal tool. However, if the burn-in is severe, it may be permanent and cannot be fixed. In some cases, the burn-in may be so severe that it affects the overall picture quality of the TV.
If you want to fix burn-in on your TV, it is essential to act quickly. The longer you wait, the more severe the burn-in can become. You can try adjusting the TV’s settings, using a burn-in removal tool, or seeking the help of a professional. In some cases, the manufacturer may be able to repair or replace the TV if it is still under warranty.

Can I prevent burn-in from occurring on my LCD TV?
Yes, you can prevent burn-in from occurring on your LCD TV by taking regular breaks and adjusting the TV’s settings to a comfortable level. It is essential to display a variety of images on the screen to prevent the same image from being displayed for an extended period. You can also try using a screen saver or turning off the TV when not in use.
Another way to prevent burn-in is to adjust the TV’s settings, such as the brightness and contrast, to a comfortable level. You can also try using a feature called “pixel shifting,” which helps to move the image slightly to prevent burn-in. Some TVs also have a feature called “image retention compensation,” which helps to remove burn-in by displaying a series of images.
How often should I take breaks to prevent burn-in on my LCD TV?
It is essential to take regular breaks to prevent burn-in on your LCD TV. The frequency of the breaks depends on how often you use the TV and the type of content you display. If you use the TV for extended periods, such as for gaming or watching movies, it is recommended to take a break every 30 minutes to an hour.
During the break, turn off the TV or display a different image to give the pixels a chance to recover. You can also try using a screen saver or a feature called “pixel shifting,” which helps to move the image slightly to prevent burn-in. By taking regular breaks, you can help prevent burn-in and extend the life of your TV.
Are all LCD TVs prone to burn-in, or are some models more susceptible?
Not all LCD TVs are prone to burn-in, but some models are more susceptible than others. The susceptibility to burn-in depends on the type of panel used in the TV, the quality of the panel, and the TV’s settings. Some TVs, such as those with IPS panels, are less prone to burn-in than others, such as those with VA panels.
It is essential to check the specifications of the TV before purchasing to see if it is prone to burn-in. You can also read reviews from other users to see if they have experienced any issues with burn-in. By doing your research, you can choose a TV that is less susceptible to burn-in and take steps to prevent it from occurring.
