After a few years of use, some issues will likely pop up with your television. Among the most common TV issues is having trouble with the LED light strips and device backlighting. LED backlights start to lose their shine after five to seven years, resulting in display problems that sour the viewing experience. Fortunately, LED light strips are repairable and replaceable. Therefore, you can make the device’s picture look as good as new again.
The Common Signs of Light Strip Issues
When a TV has problems, we tend to notice them through the screen’s display before anything else. LED light strip issues are all noticeable based on your TV’s picture quality. Examples of problems include failing bulbs, low backlight power, or dead light strips. The following are some of the most common signs that indicate an issue with your LED light strips.
A Flickering or Flashing Display
A flickering or flashing display is one of the most subtle signs your TV’s LED light strips need to be replaced. This issue can take time to notice, as it may blend in with the movie or TV show that you’re watching. But over time, the flashing can become more noticeable.
One or two specific areas might flash if bulbs go out individually, or the entire screen may appear to flash as the set of strips go out. If you don’t address it, the flickering or flashing may become more frequent with time as the light strips continue to age and fail.
Dim Lines, Areas, or Screen
A symptom of malfunctioning LED light strips that’s much easier to diagnose is a dim screen. These dark areas can appear as straight lines or patches. They can also span across the entire display. If one light strip has failed, that portion of the TV may suddenly become dimmer than before. Individual bulbs failing to light up can also cause dim regions.
Entire strips will ultimately be easier to replace than individual bulbs. Sometimes, only one bulb goes out, though. Thankfully, if you want to replace the LED light, you have the option to do that as well.
A Cloudy or Fuzzy Picture
When your TV’s image is cloudy or fuzzy, this is usually a sign that the backlighting has become uneven. This issue will be especially visible when the image on the screen is very dark. A vivid, pure black picture will appear cloudy when one side has more light than the other. This lack of uniformity can be a problem with the light strips or the backlight inverter board that powers the lights.
A Black Screen While the TV Is On
One of the most gut-wrenching TV issues to experience is an entirely black screen. This problem can become more confusing when you can still hear audio playing. But it’s a good sign when you can perceive audio and see the power lights. In such cases, the issue most likely only relates to the display.
If you see an all-black screen despite knowing that the TV is on, the picture may still be playing. If the backlights have gone out, there is no way for the device to illuminate the picture in a way that makes it enjoyable from a distance.
Diagnosing the Problem
Some of the signs your TV’s LED light strips need to be replaced are also signs of issues with T-Con boards and other TV parts. This is because many kinds of problems are diagnosable through the display. Fortunately for owners, there are a few ways to confirm that the source of the poor picture quality is the light strips. Here are three ways to check if the LED light strips are the problem.
Start in the Settings
The first thing to do when having display issues is to pull up your TV’s settings. Before beginning the repair process, you want to ensure that the problem isn’t solvable by correcting any picture mode, power-saving, or automatic brightness controls that could impact your display.
You may see no effect when changing the display settings of your device. If so, the issue is probably a result of malfunctioning TV’s parts instead.
Check With a Flashlight
If you’re struggling to see the image on a dim or entirely black screen, you can check to determine if the problem is the light strips. You can do this without opening your television first. Turn off or lower the lights in the room and use a flashlight to check the display.
When a backlight or light strip has failed, you’ll still be able to see the picture under a flashlight. This test also lets you know that the boards that generate the image are still functioning, allowing you to rule out other problems.
Reinstalling vs. Replacing
Before purchasing a new LED light strip, you want to check that the current light strips aren’t loose or incorrectly installed. Light strips must align and have the correct length for the model to generate the right backlighting. Often, dim spots in the corner of the display can manifest due to improperly installed light strips.
Replacing the Light Strips
Accessing the light strips requires some technical skill. The most significant issue for those looking to repair an LED television will likely be protecting the LCD panel itself while trying to access the light strips. These fragile parts are costly and virtually impossible to repair. So, you need to take great care when opening an LED TV.
However, once inside, you’ll need to remove the chassis or film protecting the strips. Once you remove this blank piece, you’ll have full access to the LED strips. You can take out most of them by simply breaking the adhesive seal on their backs and pulling them up as you go.
Though the process of getting to the LED light strips may be intimidating, the resulting picture quality is worth the effort. LED light strips must be compatible with your device. So, knowing the exact model you need will be essential for successfully replacing your light strips.
