white dots on lcd screen brands

If you find yourself in a situation where you notice white spots or dots on your TV, don’t worry. This problem is known to occur on most LCD TVs and it is really simple to solve. White spots (dots) that you notice are the light from the LED backlight inside your TV.

Due to frequent use or poor quality, some parts inside the TV can move from their spot and cause white spots or dots to project onto the screen. In this article, we’ll explain why this problem occurs and how to solve it. So, let’s start.

So What Causes White Spots or Dots on TV Screen?White spots or dots on LCD TV are a result of a fallen 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 on the screen. Usually, they fall off due to the poor quality or the heat that is created inside the TV.

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

There is also a similar problem with LCD TVs, and that is the creation of dark (black) spots on TV. If you are interested to learn What Causes Dark (Black) Spots on TV Screen, read the following article.

As we said above, these white spots or dots that appear on LCD TVs are most often the cause due to overheating problems and the poor built-in quality.Anyone who has paid attention knows that older TVs are practically not affected by this image error.

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

LED Reflectors: Each LCD TV comes with a reflector (lens) that helps to facilitate and spread the LED light on the screen. Sometimes, these reflectors get to loosen up and they fall off from their spot. When that happens, you will notice the white bright spot on your TV screen. In most cases, you will have several white spots (dots) on your screen, not just one.

Whether or not you have previous experience in repairing TVs or gadgets, if you follow the instructions below, I believe you will be able to fix your TV and get rid of the white spots on your TV screen. You will need to disassemble your LCD TV and return the fallen reflectors to their original place with the help of glue. What you will need is the following:

If you already have an LCD TV or have decided to buy one, the testing process is identical. I always do a test before I decide to buy a new LCD TV. Even new models can have problems with white spots or dots. During transport or by the poor installation quality, round reflectors can fall out of place and cause white spots. So, to test a TV before buying and see whether the image defect is present you can do a simple test.

There are different TV models (types) where this problem with white spots or dots can occur. On some TV models, the problem that causes white spots may be different, so it is necessary to know how to proceed.

Also, keep in mind that if you encounter a more complex problem, leave it to the professionals. In the table below, you can see how to fix the problem with white spots or dots for different TV types:

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

When the reflector or lens is moved from the spot, it causes these white dots to appear on the screen. But in some cases, there might be more damage on your TV screen than just a moved reflector or a dead pixel and it can cost you more than a new matrix.

Therefore, it is recommended to contact the TV specialist if you notice that the problem is not only with the moved reflectors but in something more. Keep in mind that if your TV is under warranty, it is recommended to contact a service center, and let them handle this problem. They have more experience with these kinds of problems and they will fix your TV for free.

The problem of white spots or dots is not something new, and it can appear on almost any LCD or LED TV whether it is completely new or used. We have already mentioned in this article that this problem can be solved very easily and you do not have to be afraid.

You can disassemble the TV and see if the reflective lenses have fallen out of place and use super glue to put them back on. If you think you can’t solve this problem on your own, contact a TV service technician and let him do the job. I hope that we helped you at least a little and that you will be able to solve the problem with white dots.

A high-quality picture of digital television depends on the correct setup of the equipment, a good receiver, and the correct operation of the monitor. Over time, even the quality models of Sony, Samsung, LG equipment, white spots may appear on the TV screen. To eliminate them, you need to find out the cause of the breakdown, decide if you can fix the TV by yourself or if you should refer the equipment to professionals.

So What Are White Spots on TV?LCD TV Screens are comprised with thousands of tiny pixels, and they cycle through 3 basic colors; blue, red, and green and they create an image. The problem arises when a pixel gets stuck in the “on” position, and it appears as a white dot. Hot pixels come with defined edges and they are either square or straight lines.

White spots (or dots) on the TV screen are the result of a damaged processor and the overheating process during warm summer temperatures.Another reason that can be the cause of white spots on the TV screens is spikes or surges as electricity supplies can vary throughout the year.On top of every LED of your TV, there sits the reflector. These white dots on your TV screen are the results of a fallen reflector. The number of dots has corresponded to the number of fallen reflectors.

If light spots appear on the LCD TV screen, you will need a clean soft cloth and remote control to remove them. The second thing to do is adjust the TV settings. This can be done by adjusting the backlight and screen brightness:

Important! In the process of changing the brightness level, the intensity of the white spots should change. If they remain unchanged, the settings are not the cause of the defect.

If wiping the screen, checking that the brightness and contrast settings are correct, and loosening the screws did not get rid of the white spots on the LCD TV screen, you can replace the matrix. It is better to contact specialists for this, but if you have experience with television equipment, you can carry out repairs on your own.

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.

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.

Thanks guys! I just replaced the leds for my tcl 55 inch tv and after bout a week I started seeing the bulbs on the left side of the screen. Since the tv was an awesome find and the bulbs were like 30 bucks on eBay I’m fighting the inevitable being going back in and fixing that plastic deflector post. The screen is extremely fragile so if u don’t wanna pay 14 bucks at Home Depot for them window suction cups that were well worth the money For loners like myself lol, make sure u get another person to help u with the screen panel once it’s been dislodged . Especially if it’s a big honker. Nothing more scary than popping it out by urself and get stuck in a very bad situation as in u can almost hear the crackin of the screen Or knowing that I’d u take one more step this here screen will crack .

Bright or white spots are a big problem with tv screens, especially on Samsung. And yet, even their formidable LCD tv screens are vulnerable to one of the most annoying TV problems: white spots.

Setting up your LCD TV can be a lot of hard work. From mounting it away from annoying glares to adjusting image settings to be most pleasing and easy on your eyes, you want to make sure that you can properly relax for your hours of entertainment.

You also want to make sure that you’re not overworking your TV. Those white dots flashing on after you’ve powered up your set can be a serious distraction, especially when they beam over darker images.

You might not be wrong, but in the case of roughly three small, white circles on the side of your screen, if not more than a dozen throughout, the problem may be deeper.

The repair costs for a Samsung TV with White Spots would usually range anywhere from around $200 to $300. This is quite pricey, so make sure you read through the whole article before you get it repaired.

This might not even solve your problem, as there could be more serious LED damage behind the white dots. If you want to play it safe, calling a technician may be more cost-effective.

The white spots on a TV are most likely stuck pixels. This usually isn’t that serious of a situation and can be dealt with through serious troubleshooting.

There is a common misconception that white spot pixelation issues in Samsung TVs stem from LED reflectors. This can also cause lines on your Samsung TV.

Screen time is as much for the screen’s health as it is for yours. Of course, overheating may also be due to your TV’s climate, particularly during the hotter seasons.

There are also fewer technical reasons for white spots, both in software and in hardware. Regarding the former, you can relax the processing power of your TV by adjusting image settings.

Most people would just see white pixel-looking things on their screen, but a few users have been reporting that they have seen white spots on their Samsung TV as well.

I wouldn’t recommend doing this yourself unless you have dabbled in electronics before, but if you’re feeling a bit confident, you can always watch a quick youtube video.

White spots on your tv usually happen because your tv has been hit in a certain area. If you can think back to a time when something hit your tv or if this happened just now, then this explains it.

It is always important to practice good hygiene with your TVs. We all know that we need to clean dust and debris off of our screens from time to time.

But then, we all also know that we should be flossing our teeth regularly. Of course, as with black spots on your teeth, white spots on your TV screen can mean getting invasive with your upkeep.

Gently place the TV on the ground, facedown, and unscrew the back case to expose the monitor inside. Afterward, gently remove the small screws along those edges.

After you have removed the screen as carefully as possible, you should be able to see any smudges or blemishes that may have snuck into the back of it.

If so, gently wipe the screen down with a microfiber cloth lightly sprayed with distilled water. Some people have recommended alcohol, but I say better safe than sorry.

You may have to use a cotton swab very lightly to remove some of the more stubborn spots. After you’re done cleaning, carefully put your TV back together.

Just for good measure, give the front of your screen a good cleaning as well. Feel free to be more vigorous than you were with the back, but still be careful with this highly sensitive equipment. If the white spots are still there, then the issue is more than cosmetic.

When setting up your TV, it is advised to adjust image settings to ease your set’s function. Backlighting requires a lot of power and should be kept relatively low if you hope to make a TV last.

If the damage is done on pixelation, there is still hope. If you are planning on doing serious maintenance with your image settings, it is recommended that you put your TV in the picture Test mode.

This will give you the option of changing to Picture Test mode, which displays the image of the color bars on your main screen. The color bars image gives you a more vivid look at an image’s color and lighting.

If pixels on your TV screen are too damaged, then it may be time to replace the screen itself. If you have managed to figure out how to clean the back of a Samsung TV screen, though, replacing one shouldn’t be too difficult. Just to be sure, let’s review it in step-by-step detail.

Step 4: Very carefully remove the television’s screen and place the new one in its stead. Make sure that it is clean and undamaged. From there, put your TV back together.

In the United States, the current service rate for Samsung TV screen replacement is around $200. That is as low as roughly $60 and as high as well over $300.

Backlight replacement service may only cost $100 or so. You can check by removing your TV’s screen and the white diffuser sheets separating it from the LED light array.

The more common cause of this issue in Samsung’s competitors is problems with LED light reflectors. If you have an LG LCD TV, for example, then maintenance on stuck pixels can be easier.

LED reflectors are small bulbs that redirect an LCD TV’s backlight to illuminate an image. Without them, the light is directed forward, thus resulting in small lapses in the image’s pixelation.

The most common malfunction in reflectors is that they have simply fallen out of position. It is usually a manufacturing error, but overheating in your TV can loosen the adhesive holding the bulbs in place.

To fix the LED reflectors in your LG TV, the steps are fairly similar to those in replacing a Samsung TV screen. If you have skimmed through the article up to this point, then let’s review it once more.

Step 4: Very carefully remove the television’s screen and carefully set it aside. Remove the diffuser sheets to reveal the LED light array and the reflectors within.

Again, though, this is considering that your issue is stuck pixels. If you are dealing with black spots, you cannot simply follow the previous instructions.

Black spots on your TV may be a much more serious issue. At best, it means that your TV screen has accumulated an excess of debris from exposure to the elements.

Even dirt on the surface of your screen can gradually erode pixelation, so be sure to clean your TV regularly. The more likely, more extreme case with black spots is dead pixels caused by power connection failure.

This problem is also known as “hot pixels”, but I’m afraid such terminology doesn’t fully reflect the seriousness of this technical issue. You can apply pressure to or lightly thump your TV to help spark a connection.

Now we’re going to go into the different color lines you can see on your screen. The main color lines people usually report to us are black, purple, and green lines on their screen.

The colors you say aren’t an indicator of what is wrong with your tv screen. Black lines are the most popular because that is the colors that are mostly used.

If you notice the lines on the bottom of your TV screen then it’s an indicator that there is damage to the bottom of your screen. At a push, black lines usually indicate that there has been damage to your tv screen.

If you’re seeing certain lines on your tv screen then the reason why is because there is a graphic failure. This may be because there is an issue with your screen or with your cables.

Due to this reason, you will see a reduced image quality and reduced graphics on your screen. The only way to overcome this is to pinpoint the actual reasons why there are lines on your screen.

Lines will usually be horizontal if the images on your screen can’t load properly. If there are vertical lines on your smart tv screen, it might be due to input cables.

If this image is too big or small for the smart tv’s resolution it will cause problems. Fixing the resolution will fix this which is what ill get into down below.

If the spots are due to stuck pixels, then a screen replacement may be needed. It is hard for a consumer to track down a replacement screen, contact Samsung’s repair services or a local independent technician for a quote.

Disassemble your TV carefully, as if you were replacing the screen, and gently glue these reflectors back into place. Of course, if you are dealing with black spots, then you are probably dealing with dead pixels.

In any case, do pay attention to the blemishes on your screen. They are hard to ignore anyways, but they may be a more serious dilemma in your relaxing at-home entertainment than they appear.

Does anyone know of a resource for causes of different types of LCD monitor defects? I"d like to know what"s causing a seemingly random spread of white dots (at least over 50, more than multiple pixel bulbs in size) to randomly appear and disappear on my screen.
