Highlights on the monitor

Often, many users have an unpleasant problem. When you buy a new monitor or TV, after some time or immediately, there is a specific glow on the screen. It is especially visible if the image on the monitor or TV is dark. Many believe that this is a factory defect, however, often users are faced with the fact that the seller does not add this problem to the list of warranty or critical failures and refuses to repair. What to do in this case will be described in this article.

How does the light on the monitor look

First you need to determine what exactly is the "light" on a monitor or TV. The easiest way to determine this malfunction is to open a black image on the screen. After which the user can see the glow from one or more points along the edges of the screen. This is the "light". You can also see malfunctions if you put the device in demo mode and completely turn off the light in the room. In this case, the user is given the opportunity to detect all malfunctions or errors in the screen.

Attention! Check the device for flashes or other malfunctions in a dark room, since the presence of third-party light sources can create glare, which will not allow the user to fully evaluate the performance of the screen.

The reasons

This problem is typical for LCD monitors in connection with the specifics of their work. The display of colors is achieved through special crystals that move. They are constantly illuminated by a special backlight, which is either a lamp or a series of LEDs (depending on the technology of the TV). Thanks to this backlight, the image on the screen changes color and brightness.

Due to incorrect tilt of the LCD crystals or a change in the position of the lamp, the light from the backlight is reflected from the surface and becomes visible to the user. Due to the fact that the matrix can move away from the screen at different distances, the light can be both strong and hardly noticeable. Also, the glow from the lamps can be either just light or color, which makes the use of this screen less comfortable.

How to get rid

Basically, most manufacturers recognize this malfunction and can replace the device only if the monitor has not been exposed to external influences and has not been disassembled.

Important! To avoid such situations, you should always check the image quality in a demo mode before buying. If the store refuses to connect the device to the network, you should think about the reasons for such a failure.

If it is not possible to take the device to a service center, there are several ways to fix this problem at home.

Attention! Remember that improper actions or excessive use of force can damage the screen.

1. The easiest way to remove the highlights is to reduce the brightness and contrast in the monitor settings. This method will help if the light is weak and covers only a small area. This does not solve the problem technically, however, it will help get rid of the malfunction, and increase comfort from use ...
2. The second method is more effective. It is necessary to “stick” the matrix back to the surface so that the light again passes only through the crystals. To do this, you need to take a lint-free towel, and leaning against the screen, slightly press on it with your hands in places of glow. This should be done carefully, but hard, as there is a risk of damaging the surface of the monitor. Then with effort it is necessary to smooth out flashes on corners. This "massage" should be carried out in a dark room on a working screen, on which there will be only a black image. This will allow the user to observe the result of their work.
3. For the third method, you first need to warm up the matrix. To do this, leave the device turned on for 2-3 hours. After that, you need to carefully take the monitor and tilt it towards you almost to a horizontal state. Then "shake" him around the corners. After that, the light should disappear.
4. The latter method is the most unsafe, so it is not recommended for users who are new to the technique. This method will require a screwdriver. The user needs to unscrew the monitor cover and then screw it back. Perhaps the problem is not enough tight fit of the screen to the body.

Attention! Many bolts that secure the mount have special seals, and if they fail, the warranty service of the device becomes impossible.

Above are the main ways to eliminate light on the monitor screen. If none of them helped, then you should seek professional help from a service center where experts can help correct this malfunction.
