What causes white spots or spots on the TV screen?

So what are the causes of white spots or spots on the TV screen? White spots or spots on the LCD TV are the result of a dropped reflector (lens) inside the LCD TV panel. These reflectors are placed in front of the LED backlight and are used to spread the LED light across the screen. They usually fall out due to poor quality or the heat created inside the TV.

When you open the TV you will find a series of LED lights covered with reflectors or plastic lenses. These lenses are mostly glued in front of the LED backlight, and as the TV gets hot with use, they start to fall off their spot and create white dots or spots on the TV screen.

Reasons why white spots or spots appear on the LCD TV screen

As we said above, these white spots or spots on the TV screen appear very often due to overheating issues and poor screen quality. Anyone who has paid attention knows that older TVs are practically unaffected by this image error.

This problem is mainly found in televisions with LED backlighting, more precisely the so-called side LED backlight. Behind the panel is a light conducting plastic plate.

There are 2 main malfunctions that cause white dots or spots to appear on the TV screen:

Dead Pixel: Each LCD and LED TV is made up of millions of pixels or dots whose main purpose is to illuminate and produce the image on the TV screen. Sometimes, the problem can occur if some pixels are damaged and get stuck in a particular state that is causing the problem and appear as white spots on the TV screen.
LED Reflectors: Each LCD TV is equipped with a reflector (lens) which helps to facilitate and diffuse the LED light on the screen. Sometimes, these spotlights loosen and fall out of place. When this happens, you will notice the white bright spot on the TV screen. In most cases, you will have several white spots or smudges on the screen, not just one.

To solve the problem of white spots on the TV screen, you will have to open the TV and with the help of the super fast glue you will have to put the fallen reflector back into place.

How to test before buying a new LCD TV

If you already own an LCD TV or have decided to buy one, the testing process is identical. I always give it a try before deciding to buy a new LCD TV. New models may also have problems with white spots or spots.

During transportation or due to poor installation quality, the round reflectors can fall out of place and cause white spots. So to test a TV before purchasing and see if the image defect is present you can do a simple test.

Ask your dealer to turn on the TV before taking it back.
Then select a dark pattern in the settings menu. If you can't find it, connect to a media source and show a black photo on the screen.
If everything is fine and there are no white spots, you can buy the TV.

Note! You can also press Pause during a movie when the screen is black to test the LCD TV to see if there are any white spots or spots on the TV screen.

When is screen replacement necessary?

White spots (dots) on the TV screen are a very common problem on LCD TVs. Almost all LCD TVs operate using a small chip made up of millions of tiny mirrors. Each mirror is like a dot or a pixel on that screen.

When the spotlight or lens moves from its original position, these white dots appear on the screen. But in some cases, there may be more damage to the TV screen than a simple displaced spotlight or dead pixel, and it can cost you more than a new television.

Therefore, it is recommended to contact a specialist if you notice that the problem is not only with the displaced reflectors but something more. Please note that if your TV is under warranty, it is recommended that you contact a service center and let them take care of this issue. They have more experience with this type of problem and will fix your TV for free.

Conclusion

The problem of spots or white spots on the TV screen is nothing new and can appear on almost any LCD or LED TV, whether they are completely new or used. We have already mentioned in this article that this problem can be solved very easily and you don't need to be afraid.

You can take apart the TV and see if the reflective lenses have fallen off and use super glue to put them back in place.
