If you find yourself in a situation where you notice white spots or dots on the TV screen, don"t worry. This problem is known to occur on most LCD TVs and is really simple to fix. The white spots you notice are the LED backlight light inside the TV.

Due to frequent use or poor quality, some parts inside the TV may move out of their position and cause white spots or dots to be projected on the screen. In this article we will explain why this problem occurs and how to fix it. So let"s get started.

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.

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.

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.

Whether or not you are experienced in repairing TVs or gadgets, if you follow the instructions below, I believe you will be able to repair your TV and get rid of the white spots on your TV screen. You will need to take apart your LCD TV and return the fallen reflectors to their original position with the help of glue. What you will need is the following:

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.

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.

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.

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. If you think you can"t fix this on your own, contact a TV service technician and let them do the job. I hope that we have helped you at least a little and that you will be able to solve the problem with the white dots on your television screen.

Those could either be pressure points meaning something is under the screen pushing up on it or it could be a defective LCD. If you can get that screen off in one piece as those spots disappear then something is putting pressure on the display. If they’re still there when you lift the screen off then it’s a defective LCD and you should contact the supplier to get a replacement or refund depending on their policy.

Display issues with your computer can make it hard or impossible to use your machine. If you see odd behavior coming from your screen, reboot the computer to see if the issue resolves itself. Should the white spots and black background reappear, it could mean that your computer has pixel problems or screen damage.

Hot Pixels Your computer"s LCD screen is comprised of thousands of tiny pixels, which cycle through three basic colors -- red, green and blue -- to create images. Sometimes a pixel can get stuck in the "on" position, and appear as a white dot. This is known as a "hot pixel," and you may be able to get it unstuck by using pixel-fixing programs such as Undead Pixel, JScreen Fix or Stuck Pixel Fixer (see Resources). Hot pixels have defined edges and are either square or straight lines.

Screen Damage If the white spots on your screen are larger than a few pixels or are irregularly shaped, your screen may have suffered some sort of damage. Examine the screen for signs of cracks or liquid entry. Damaged screens aren"t repairable, so you need to completely replace yours if it"s damaged.

Hardware Failure In some cases, display issues occur due to hardware failure, such as with the video card. To rule this out, connect a second monitor, and then check for any display issues. If the picture on the new monitor appears properly, the problem lies with the first monitor. If the second monitor shows the same display issues as the first, your video card may have failed.

My laptop"s (Dell Latitude D630) LCD screen turned black but the system is running fine.  I purchase a replacement LCD screen and now it has a large white spot at the bottom right of the screen at the login screen.  Then after I login, the white spot moves to the left hand side.  So I reached out to the vendor for another replacement, but once I put the screen in, the white spot is on the same area at login and after logging in (see attachements).  I know the hard drive and o/s are fine b/c I connected a monitor and everything looks great.  So I"ve ruled out that the LCD screen is not the cause...now what?

so disappointing with Samsung and my 65 inch TV. Only 5 years old and I have white spots on my screen. After doing some research I find it is because some of the filter lens have come un glued causing the LED light to shine through. This is clearly due to poor workmanship. I called Samsung and they tell me sorry you are out of the warranty period. Would you like to buy a new Samsung TV, we got some great deals for loyal customers. First why would I buy a new Samsung TV when you do not make a quality product. Second the price quoted was the same as at Best Buy. So no big savings. I have a Sharp TV that is 15 years old with a perfect picture. I wanted a smart TV and thought I purchased a quality TV but now I know I did not! Make it right Samsung send me a new TV that works.

Electronic products will have some minor problems over a long period of time, and the same is true for the stretched LCD bar screen. What kind of issues will occur when the stretched LCD bar screen is used for a long time? The stretched LCD bar screen is used for a long time, the faults of the LCD screen are rough as follows: white screen, blurry screen, black screen, dark screen, yellowing, white spot, bright line, bright band, dark line, dark band, outer membrane scratch, etc.

Among these faults, it is relatively easy to repair the dark screen, yellowing, white spots, and outer membrane scratch. The dark screen is actually the aging of the lamp tube, and it is enough to replace it directly. The yellowing and white spots are both issues of the backlight source. Corresponding backlight sheet or light guide plate can be solved. Scratching of the outer film means that the polarizer covered on the surface of the liquid crystal glass is damaged, and it can also be replaced manually.
