How To Remove A Dead Pixel On The Monitor
UndeadPixel will fit most
Go to the official website and download the program installer. I recommend the installation version, not the portable one.
In the main window of the program, it is proposed to start finding dead pixels by filling the screen with solid colors: red, lime, blue, white, black and yellow. Different broken pixels will show up on different backgrounds. If you already know where your pixels are, then immediately proceed to restore.
UDPixel works like this: a square appears in which colors change quickly, i.e. there the pixel recovery aLGorithm works, and we need to move this square to the Problem spot on the screen. In the “Undead pixel” section, you need to set the parameters:
- Flash windows. the number of squares, i.e. how many problem areas are you going to treat at the same time
- Flash size. the size of one square in 1×1 or 5×5 pixels. Since it is very difficult to set a 1×1 square exactly 1 pixel, then a 5×5 area is suitable to restore even one pixel.
- Flash interval. pixel refresh rate by aLGorithm. The shorter the time, the faster the speed. Maximum speed at 3 ms.
Press Start and move the twinkling square (s) to the Defective spots, see below. When the pixel starts blinking, then this is already an application for victory, just leave it for a longer time. If everything is unchanged, then select the maximum speed and wait until the pixel disappears. In the worst cases, it can take 10 hours, there is no point in waiting any longer.
The peculiarity of UDPixel is that during the recovery of pixels, you can continue to work if the squares are not large and DO NOT interfere.
Dead pixel recovery software
High-tech methods used only in laboratories are not worth talking about. Is it possible, in principle, to get rid of multi-colored dots at home? Yes it is possible! And I was convinced of this myself. There are two ways to eliminate dead pixels. software and mechanical.
The restoration is carried out by quickly changing the colors of adjacent pixels. Thanks to this process, a large amount of energy is supplied to the subpixels and they come to life. This technology promises to recover from 55% to 90% of “stuck pixels”. True, each case may take a different amount of time, you will have to experiment if you cannot remove the damaged pixels with the raids. Experiments mean changing the speed of changing colors and running time of the program.
The recovered pixel may become overwhelmed after a while, especially in hot weather. Then the treatment process will need to be repeated. In some cases, such a pixel cannot be completely cured.
Recovering dead pixels on screens
Summer has begun, heat and new fun. I have a one-room apartment and, imagine yourself, I decided to put a second computer in the kitchen with a 19-inch TFT monitor! And what does summer and broken pixels have to do with it? And here’s what. 36 degrees outside, the stove, oven and high humidity did their dirty work. a couple of dead pixels appeared on the monitor.
Dead pixels are constantly glowing or vice versa. non-working dots or parts of dots (subpixels) on the monitor. If the pixel does not work at all, then it always looks black and is noticeable only in white and light colors. This is the most harmless kind of dead pixels, but it is practically NOT amenable to treatment.
The most common broken subpixels are when a bright red, blue, green, yellow, turquoise or magenta dot is constantly lit. They are also called “stuck” pixels (stuck pixels). If such a pixel comes out in a conspicuous place. it is very annoying, especially the red # 128578; If all three subpixels are buggy, then a white dot will glow on the screen.
By the way, defective pixels can either appear or disappear by themselves. On my main monitor from the purchase itself, there were three multi-colored dots in the middle of the screen. When buying, I either did not notice them, or they appeared already at home, I don’t know. But I did not bother on this score, because they were completely invisible to the eye, if not peering. For 4 years of working with this monitor, I never noticed them, although they were in the middle of the screen.
I think this is due to the fact that my monitor is on the MVA matrix, and not on the common TN. Probably, the specificity of the matrix is such that small defects are NOT noticeable. So, I recently decided to check if these pixels can be removed in a new way. Began to check. but they are not! All have gone somewhere in formation # 128578;
JScreenFix for browser
This is not a program, but just a website, a free service on the Internet. Thanks to this, JScreenFix can be run on any device with the Internet: computer, laptop, tablet, MacBook or LCD panel.
Scroll down the page and press the Launch JScreenFix button. The JScreenFix script restores dead pixels in the same way as UDPixel, only without the ability to change the parameters, and it will not work at this time to work at the computer.
You need to move the iridescent square to the problematic pixels, and if they are outside the browser window, then switch to full screen mode by clicking the green button. Check out how Undead Pixel and JScreenFix work:
Recovering dead pixels
Hello, friends! With the entry of LCD monitors to the mass market, free space began to appear on the desktop), the background radiation noticeably decreased and everyone breathed a sigh of relief. However, in liquid crystal monitors, in addition to the huge positive sides (diagonal 21 “and more, absolutely flat screen, the possibility of wide-format performance) there may be “negative” points, called dead pixels. What it is and how you can try to restore these points I will tell below.
A little bit in dead pixels
In a modern LCD monitor, an image is built from dots called pixels. The word “pixel” itself comes from the abbreviation. pix element or piсture cell.
The number of pixels is determined by the resolution of the monitor. eg:
1920 x 1080 = 2073600 pixels
Each pixel consists of 3 subpixels: red (R ed), green (G reen) and blue (Blue). Hence the abbreviation R G B.
To set a certain color of a pixel, you must specify the brightness values of 3 subpixels. Each value is indicated by 2 digits in hexadecimal format (00 minimum brightness, FF. maximum brightness). For example: black color. 00 00 00, white. FF FF FF, red. FF 00 00, etc.
There are two types of “broken pixels”: “dead”. which have little chance to restore (they are permanently white or black) and “stuck”. which burn in a certain color. It makes sense to restore these.
Before “curing” broken pixels, you need to determine exactly where they are. For this, the AIDA64 program or any other program with a test for monitors is suitable. Download, Install. The “trial” version is also suitable for us.
The UDPixel program is also perfect. Considered below.
Let’s show with the example of AIDA64
Launching and Opening the “Service” menu. Select the item “Monitor Diagnostics”
The following window will open
If you know what tests you need, leave the birds only on them, if you do not know, leave everything as it is and starts the test by clicking the “Run Selected Tests” button. Next, change the images on the screen with a space and look out for these very broken pixels.
They are especially noticeable when viewing a picture of a fully filled screen in a certain color. (My former boss used a magnifying glass to find dead pixels)
Why Sometimes You Can’t Return Your Monitor Under Warranty?
All monitors are divided into classes.
- 1. in which there are dead pixels and, if they occur, a Warranty replacement is carried out
- 2. allows a certain number (up to 7) of dead pixels (depends on the diagonal of the monitor)
- 3. up to 70
The most common is the 2nd grade. This characteristic should be indicated in the specification for the monitor. If not specified. class 1 monitor.
Therefore, if your number of dead pixels does NOT exceed the acceptable in its class, the probability of product replacement is very low.
We decided on the location, we are trying to restore.
Bad Crystal. dead pixel recovery and prevention
Let’s start with software recovery methods. They are safe, i.e. Should NOT make the situation worse.
All software methods use fast color change in the “sore” area. The probability of dead pixels returning to a working state, more than 50%.
Bad Crystal is a paid program. The demo version has a pretty good tool. We will use it.
Download, Install and run the program. Click on the arrow circled in a red rectangle
In the opened window with activation, click “Continue”
If you want to restore dead pixels on the screen of a phone, TV or game console, press the same arrow and select your product. We’ll stop at a computer monitor. Click “Fix Now”
In the trial version of the program, it is possible to use only CCM mode with an efficiency of more than 55%. In the activated version, more efficient SMF and CFV modes are available with a recovery rate of up to 80%. PPM is a prophylaxis regimen. It is necessary to run a couple of times a month if the dead pixel is successfully restored to life.
Select CCM mode and click “Launch”
Hover the opened window over the broken pixel and wait 10 minutes. Checking. If nothing has changed, increase the speed (press Speed Up) and leave it on the “sore spot” for 20 minutes.
Checking. Increase the speed to the maximum and leave for 30 minutes. If it does not help, leave it overnight. If this does not help, go to physical methods.
If the broken pixel comes to life, then the program developer recommends conducting preventive maintenance (PPM mode) 2 times a month.
We select the PPM mode. In the window that opens, click “Manual Mode” and minimize all windows
The screen is “massaged” with different colors. Wait for completion and close the program. If the program does NOT close, use the task manager and remove the selected tasks
For prevention, you can also use the following on which the “massage” is written.
You need to download, unpack, run and point to the disinfected place.
Recovering a broken pixel “manually
Software methods are completely safe as opposed to “physical”.
Take an ear stick or pencil with a grater on the back end or any other soft blunt object.
Find our “stuck” pixel and set the tool to it.
We make light pressure to the appearance of the first “stains” and release
Checking. If it doesn’t help, add “newtons” and repeat.
Then we move on to circular movements. Make the radius as small as possible. It is necessary to perform movements in both directions.
If it doesn’t help. Make light pressure on the broken pixel and move the tool up a few pixels. We do the same in all 4 directions, then back to the center (in a pixel bit)
If it does not help, then we take a sharpened pencil not an island and through a cloth napkin (so as NOT to scratch the surface), we repeat all the exercises.
If this did not give results, then it is necessary to combine the software and “physical” methods.
UDPixel. Free Dead Pixel Recovery Tool
This software product is free and allows you to work almost comfortably at the computer while performing recovery.
Download, Install and Run
In the Flash Windows field, you can select the number of “mustard plasters” equal to the number of dead pixels. For example, take 5 and press Start.
5 flashing dots will appear at the top left of the screen
Each point must be moved under the broken pixel for 10 minutes. If it does not help in betting on 20, 30 or more.
The beauty is that you can choose the size of the “mustard” 1 X 1 pixel or 5 X 5 pixels. Thanks to this, you can not distract from work while treating the monitor. Unless, of course, this does not annoy you.
In order to stop treatment, you must press “Reset”
UDPixel also allows you to conveniently test the monitor by clicking on the Matching Colors in the main program window. over, it is possible to choose any color clicked on. the case here is yellow
The function will start in the “Run cycle” cycle, indicating the number of cycles, it will help carry out the monitoring of the monitor 2 times a month.
If the software does NOT help, you must go to physical or “manual” methods.
In this article, we met with you already a rare defect. broken pixels. We figured out why it can be difficult to hand over the monitor under warranty.
Acquainted with software (Bad Crystal and UDPixel) and “manual” methods of treatment.
Therefore, the main and most reliable means of dealing with broken pixels is to check the monitor immediately after purchase and return if necessary.
Thank you for sharing the article on social media. Good luck to you!
How to remove dead pixels
Since black pixels are the result of damage to the transistor, they cannot be repaired without replacing THESE components. And this is almost unrealistic even in laboratory conditions. The situation is different with colored dots, which appear due to freezing of subpixels. You can try to remove them.
What pixel defects are there
Beats call any Abnormal pixels, Visible against the general background, but this is not entirely correct. Really broken or dead pixels are only those in which the transistor has failed. They do NOT glow in any color and just remain black, falling out of the matrix grid. Clearly visible on a white background.
Left and right pixels are frozen, in the center. broken / digital-boom.ru
There are also frozen or stuck pixels. these are red, green, blue or white dots, which are clearly visible on a black background. They occur when subpixels freeze when updating colors.
How to check the display
You can visually determine the absence of defective pixels by carefully examining a solid white, black, red, green and blue background. To do this, you need to download such pictures to a USB flash drive and play them on the device you like. If none of the dots are out of the general color, then everything is in order with the screen.
Another option is to use special software if you can run it. In fact, these are the same color pictures, but in a more convenient format for applications or online services.
- Dead Pixel Tester is a simple open source utility for Windows. After starting, you need to select the mode and carefully look at the screen.
- InjuredPixels is another free Windows app. Colors are switched by mouse or using arrows.
- Dead Pixel Buddy is an online color checker tool. Works in any browser, including mobile ones. Don’t forget to enable full screen mode.
- LCD DeadPixel Test is another online service. Choose a color, expand the window to full screen and check.
The method consists in the cyclic output of rapidly changing images, which, due to frequent color changes, increase the chance of returning the hung pixels to the ability to switch again.
There are many options for implementing this method through utilities, online services, and even YouTube. They can be used on a computer, as well as on a TV when connecting a PC with an HDMI cable.
- Bad Pixel is a professional paid utility for Windows, the creators of which promise to remove Defective pixels in just 10 minutes.
- DeadPix is a universal program for Windows and Android that helps you find and then fix problem pixels using color cycling.
- PixelHealer is another utility for Windows. Eliminates stuck pixels with fast flickering RGB colors.
- JScreenFix is an online service to run on computer, TV and mobile devices. Outputs an area with digital noise that can be moved to the desired area of the screen.
- PixelFixel is a 12-hour YouTube, which is suggested to run and leave overnight. Attention! The colors change at a very high rate and can cause an epileptic seizure. Do not look at the screen, but rather turn it to the side.
What are dead pixels
In all LCDs, an image is formed from a grid of pixels. They consist of three SEPARATE subpixels of red, green and blue, which are responsible for full-color image formation. Each subpixel has a transistor that controls its on and off.
It looks like a broken pixel on the screen / overclock.net
Even the matrix of a conventional HD monitor contains over 6 million subpixels, and in 4K displays their number reaches 37 million. With such a huge number, some of the transistors can malfunction. Then certain subpixels remain on or, conversely, off.
How to check a monitor or TV for dead pixels and get rid of the problem
You will need a free app, a Q-tip, and a little patience.
How many dead pixels are allowed
It seems logical to replace a computer monitor or TV with broken pixels, but manufacturers DO NOT consider the latter to be a factory defect. When you contact the service with a similar complaint, you will most likely be denied service.
Dell Dead Pixel Policy / dell.com
Different suppliers have their own standards for the number of defective pixels, depending on their location, resolution and display diagonal. So, LG considers up to 10 frozen and 3 dead pixels on 20-inch screens to be the norm. Samsung has 7 dead pixels for monitors, while Dell has 1-6 stuck pixels and 6-13 dead pixels, depending on the display line.
Another way is to physically influence the screen. A little pressure helps to clear up stuck pixels and get them back into working order. The method does NOT work in all cases, but you can try.
- Locate the glowing pixel and unplug your monitor or TV.
- Take a cotton swab or pencil eraser.
- Gently press the display in the area of the frozen pixel several times.
- Wait a few minutes, turn on the monitor and check the result.
Keep in mind that even if the frozen pixels are gone, they may reappear. It is also possible that after the described manipulations new Defective pixels will appear.
If there are few colored dots and they do not really interfere with work, it is better not to pay attention to them and leave everything as it is.
What are the broken pixels?
On the monitor, you can see broken pixels of various types, these are:
- On a black background, white dots are the first type,
- On a white background, black dots are the second type,
- Multi-colored pixels, green, red, magenta and blue are the third type.
In simple terms, a broken pixel is constantly glowing white or colored, as well as black dots, which DO NOT react in any way to a change in the color rendering of the monitor screen.
All of the above types are legalized by the international standard ISO-13406, which also regulates the permissible number of dead pixels in different classes of monitors.
Much depends on the model of the matrix used, so when buying an LCD monitor or laptop, be sure to turn them on and check for such problems.
- Monitors of the first class are considered to be the best and should not have dead pixels a priori.
- The second class allows the presence of NOT more than 5 problematic pixels of the III type, no more than two failed pixels of the first and second types.
- The third class assumes the presence of at least 50 defective squeaks of the III. type, by the 15th of the second and up to 5 of the first types.
- The fourth class allows the presence of 500 defective pixels of the III type, 150 of the second and, accordingly, 50 of the third types.
At the heart of the device of each pixel is a thin-film transistor, which controls the entire process of color rendering at a specific point on the screen.
If this transistor is out of order, then we can observe a black dot on the screen and we will NOT be able to change something at the software level.
Such a pixel can be noticed only on light screens or where the picture is transmitted in white.
Therefore, as a rule, despite the fact that the black pixel cannot be repaired at home, it is rarely paid attention to, since it is the least noticeable and does NOT irritate the eyes.
Other types of dead pixels are called “stuck pixels”. They glow in different colors and very much annoy the PC user, as they are clearly visible on the screen.
Here, as a rule, with this broken pixels, users of laptops, LCD monitors and other devices that use a similar technology in the operation of screens are struggling.
How to remove a dead pixel on the monitor
There are several reasons why a dead pixel appears on the monitor. This is the long stay of the LCD monitor outside the premises typical for such devices, for example, in the kitchen, where, in addition to constant temperature fluctuations, there is a lot of humidity.
We are not talking about fatty vapors in the air, which penetrate into the inside of devices and negatively affect their operation.
Mechanical impact on the monitor is a frequent occurrence when you press your finger on the matrix with an excessive force. And many other reasons.
But you need to understand that a dead pixel can be present on a new monitor or laptop matrix, and for many models of such devices this is considered a normal phenomenon.

How to remove dead pixels?
To remove a dead pixel on the monitor, I mean “stuck pixels”, at home, you can use three main methods:
There are situations when Defective pixels disappear by themselves during long-term use of the monitor, but this is a very rare phenomenon and you should not count on it. over, if the problem arose in the most prominent place and interferes with work.
The method which is the most popular in solving our problem, since in 80% of cases it helps.
The principle of its use lies in the fact that during the operation of a special program with a fast frequency, the colors of the pixels located next to the broken one change.
As a result, a larger amount of current flows to the problem area, as a result, the defective pixel is gradually reanimated.
In each case, the recovery time for a dead pixel may be different, it all depends on the complexity of the situation and on the program settings.
In the settings of the utility, you can change the frequency of color changes and the period of its operation. In some cases, it will take from 20 minutes to 5. 6 hours to solve the problem.
Programs for finding dead pixels.
If you go to test your monitor for dead pixels, then you can use a simple free utility IsMyLcdOK.
There are versions for both 32 and 64 bit systems.
Installation of the program is NOT required.
Launched the utility, this window will appear.
Acting according to the instructions, you can quickly check any monitor, including the one you want to buy for broken squeaks. The size of the program is about 200 Kb.
Dead Pixel Tester 3.00.
Multifunctional utility for checking and testing monitors. Has many features, including check for dead pixels.
Very easy to use, so there is no point in describing its work.
Dead pixel recovery software.
The most famous and one of the most effective programs is Bad Crystal. Developed in three versions Ultimate, Mobile and Primary, respectively, it has different functionality. Considered one of the best in this category of software.
At the moment, the current version is 6.1.9 BUILD 4061, the official website of the program is z-drex.com. Here you can also read how to use the program.
Description of Bad Crystal.
You can also use previously released working versions, which are not difficult to download from torrents if you feel sorry for paying 14.99 for the rarely used Bad Crystal program.
Let’s consider the work of the program using the example of version 3.0 Ultimate.
After installing and launching the program, a window will appear with the ability to select operating modes.
If you have a trial version, then in this case only CCM mode will be available. The efficiency of this mode will not exceed 55%.
efficient SMF and CFV modes work only in the paid version and provide pixel recovery in 80% of cases.
PPM mode is used for preventive maintenance, which should be carried out after recovery procedures, at least once a month.
After selecting the desired mode, click “Launch”.
A window will appear, which must be put on a dead pixel.
By default, the program will run for 10 minutes. If within such a period of time the dead pixel has not disappeared, click Speed Up and change the settings. You need to increase the speed and time of the program.
It is essentially a free Java application. To use it, you need to go to the official website jscreenfix.com and click on the “Launch JScreenFix” button.
You will go to this page with a square with running pixels.
Move this square to the problem area of the screen. By default, the program will run for 10 minutes.
If the problem is not resolved, you can increase the time of the Java application.
The program is free and fully functional. After installing and launching it, this window will appear.
For example, 5 dead pixels were detected. We expose the Appropriate settings and press start.
Five blinking dots will appear in the upper left part of the screen, each of which must be placed under the broken pixel.
Check the result after 10 minutes. Extend the run time if necessary and repeat again.
UDPixel has a second useful functionality.
The mechanical method of recovering dead pixels can be used both separately and together with the above described programs.
The essence of this method is as follows:
- The place of the dead pixel on the screen is marked in any safe way, the monitor or laptop is turned off;
- Take a toothpick and wrap cotton wool around it. Or you can use an ear stick or other object;
- With this device, gently press on the pits of the pixel, with a little scrolling. Don’t overdo it.
After a while, turn on the device and check the result, if necessary, repeat these steps several times. Be patient, all this can take up to 30 minutes.
If everything works out, run one of the above programs and effort effect.
Some people use the same method, but when the monitor is turned on and in parallel, they still use the program. But this method cannot be called safe, so we do not recommend it.
There is another way, using the stylus from the PDA.
To do this, you will need to very accurately set the stylus in front of the dead pixel, fix it in this position and turn off the monitor.
Do not press the stylus firmly against the screen and without reducing the pressing force will turn the monitor back on. When the screen is fully operational, remove the stylus, removing this effort on the dead pixel.
If the first time did not give an effect, repeat everything from the beginning by manipulating the force per pixel and positioning the stylus.
This is how we try to move the “stuck” pixel out of place and make it work correctly. In 80% of cases it turns out to be done.
This method can help in 20% of cases and this is a good chance to correct the situation in our favor.
Disconnect the monitor from all power sources. mains, card, etc. Remove the battery from the laptop by completely de-energizing it. Don’t forget about the internet cable.
Leave the device in this state for several days, for example, on the weekend you went to the country.
During this time, all the capacitors of the monitor will be discharged by 100%, and the residual current will go out of the thin-film transistors.
When you turn on the device, there is a possibility that the stuck pixel will work.
PRECAUTIONS: it is not recommended to use fingers to “massage” the dead pixel, as they have a large area of contact with the monitor and, when pressed, can damage nearby working pixels.
This also applies to objects with a large area of contact.
As we can see a broken pixel in the monitor in most cases, with the exception of black, can be restored at home.
Actions do NOT require much knowledge, the main thing is to learn how to use the required software correctly and do not overdo it with effort during the mechanical procedure for correcting the problem.
But do not forget that the presence of broken pixels is possible in new devices, so carefully check them for such a malfunction when buying.
How to fix dead pixels on an LCD monitor?
You probably already know that the image on the monitor screen is built from colored dots. pixels. The smaller these dots and the more there are per unit of screen area, the higher the image quality. However, even a good monitor is not immune from one small, but very difficult problem. “broken” pixels. What are “broken” pixels and can you get rid of them??
In liquid crystal monitors, as well as in cathode-ray monitors, each pixel is formed by three sub-pixels of a strictly defined color: black, red and green. To get a pixel of the desired color, the position of the INDIVIDUAL sub-pixels is changed, as well as the direction of the light beam and its power.
A “broken” pixel on the LCD monitor appears if the thin-film transistor that controls it is faulty. In this case, the “broken” pixel looks like a black inactive point that does NOT react to changing images. Such a “dead” pixel cannot be corrected at home, because the defective transistor needs to be replaced.
But there is another kind of “broken” pixels. these are light points, which are clearly visible against a dark background. Such pixels are obtained if one of the subpixels is “stuck” in a certain position. Then, against the background of the color in which the pixel is “stuck”, it is absolutely invisible. Therefore, it is rather difficult to identify such a problem at first glance.
In order to find “broken” pixels, you need to do some kind of check. There are special utilities (for example, Nokia Monitor Test) that test the monitor for such pixels. The essence of the action of THESE utilities is that the user is offered monochromatic pictures of different colors. Switching colors, the user visually assesses whether there are “dead” pixels on the screen.
According to this standard, monitors can be divided into four classes. The first class does NOT allow for dead pixels at all. The second one allows 2 defects of types 1 and 2, as well as 5 defects of the third type. Displays of the third class can have up to 5 defects of the first type, up to 15. of the second and up to 50. of the third type. Finally, the fourth class of monitors resolves 50, 150 and 500 defects of the first, second and third types, respectively.
“Stuck” pixels, in contrast to “dead” ones, you can try to restore programmatically or by mechanical manipulation.
The essence of the mechanical method is the physical impact on the “stuck” pixel, as a result of which it “falls” into place. To do this, gently massage the defective area of the display with a suitable object, best of all with a cotton swab. Do not massage with your fingers or any sharp objects. this can damage the anti-reflective coating of the display.
Turn off your monitor before starting this procedure. After a few minutes of “massage” you need to turn it on and see the result. You need to repeat the procedure several times.
Another option for “massage treatment” is to use the PDA stylus. In this case, cover the screen with a clean paper towel or rag. The stylus should be placed as accurately as possible on the defective pixel and, if it does not absorb it, turn off the monitor. Next, you should slightly press on the “broken” pixel and turn on the monitor again. Stop pressing. If it didn’t work the first time, you can repeat this cycle again, changing the pressure and positioning accuracy of the stylus.
Such methods do not give a 100% guarantee, moreover, there is a risk that the pressure will be too strong and the pixels adjacent to the “stuck” will be damaged. Therefore, before taking “extreme measures”, you can try to correct the situation programmatically.
A little trick. If you disconnect the monitor from all cables and wires connecting it to the computer and the network, and wait a few days, then all the capacitors of the monitor should be completely discharged. After that, when you turn on the “stuck” pixel, it may start to function normally again.
There are various utilities for software elimination of “broken” pixels. One of them is jscreenfix, which is available to users online directly from the developers’ site. After starting, you need to move the program window to the defective area of the screen and leave the program to run for at least 20 minutes. If after 20 minutes the “broken” pixel has not been removed, then you can try to run the program for 5-10 hours.
The program performs high-speed color change of INDIVIDUAL pixels, which allows you to align the stuck pixel.
Thus, some types of “broken” pixels are still amenable to “treatment”. However, so that later you do not have to bite your elbows out of frustration, you should be more careful about choosing a monitor when buying and always require the seller to test for “broken” pixels.
There are dead pixels on the TV screen. how to remove?
Is there a black, white or colored dot on your TV monitor? This is a dead pixel. It would seem just a small point. If black or white dots are not always visible, then colored dots, especially red dots, are very annoying and interfere with TV viewing.
reasons for the appearance
The cause of defects is in the technology itself. Liquid crystal is very small and unstable. Any extraneous influence during production can lead to its malfunction. It can be dust particles that got on the matrix during assembly, mechanical damage to the crystal substrate, increased voltage, heating, etc. Experts say that there is not a single fully functional matrix. Each of them has 1-2 defective crystals. A violation is considered if their number began to increase and the defect became noticeable.
The appearance of defective elements can lead to:
- excessive overheating or cooling;
- a nearby powerful source of electromagnetic waves (for example, a microwave oven)
- mechanical damage to the screen.
How to identify dead pixels
- display a white screen to identify black or colored dots;
- display black screen to see white dots.
This is a rather laborious process, but it will allow you to purchase equipment with a high-quality matrix.
What are pixels
Modern plasma or liquid crystal televisions are characterized by high image quality. And although they differ from each other in the way they form the picture, the essence of their work is the same. The smallest unit of an image is a pixel or point of light. It consists of red, blue and green sub-pixels. 4K TVs have yellow subpixels.
Broken or damaged points can look different:
- black. visible on a white or colored background;
- white. visible on a dark screen;
- colored dots.
Each pixel is powered by its own transistor. If the latter is faulty, then the pixel stops working. It will appear as a black dot on the display.
White dots appear if all subpixels are lit at once (green, blue, red).
Another type of damage is when a pixel only burns in one specific color. They call it stuck. It will look like a static spot of some color on the screen.

It is almost impossible to remove black dots on your own. Since the defect occurs due to a breakdown of the transistor, when replacing it, special equipment and work experience will be required.
Stuck color pixels can be repaired by yourself. There are several ways to do this:
- You can awaken the stuck element by pressing on it. To do this, you need to remember the place on the screen where it is. Turn off the TV. Gently press a cotton swab into the area of the non-working element. Hold it for a few minutes. After that, turn on the TV receiver to check the effect. If the result is negative, repeat the procedure again. This technique is only suitable for liquid crystal models. This is explained by the fact that the liquid crystal can be slightly moved by physical impact. When using this technique, remember that the LCD panel is very fragile, so do not use hard, piercing or scratching objects.
- Using special programs to eliminate broken elements. Run the program for half an hour and repeat every 4 hours several times during the day. The action of this program is based on the fact that it detects a dead pixel, and makes it intensively change colors in this place on the screen. Frequent color changes shakes the pixel and, as it were, provokes the launch of a stuck element.
If you decide to repair the TV yourself, then you should remember that even if there is one dead pixel on the TV, this is a warranty case. And the manufacturer is obliged to replace the panel free of charge. Unauthorized repairs can lead to the denial of warranty service for the equipment. Therefore, if the equipment is still under warranty, then with any malfunction, even a minor one, you need to contact a specialized service center.
There are many software solutions used to activate a stuck pixel. Among the assortment, the most popular will be:
- Bad Crystal is shareware with a 30-day trial mode. Although the properties are limited, there is enough functionality to fix errors, which is what is needed in this situation. And if you use the old modification and remove the darkening of the active program window, you will be able to use the full potential. Suitable for smartphones, TVs or consoles.
- JScreenFix. the application is launched through Java, which should be taken care of in advance. It detects damaged points for free, but it will require payment for activation. The well-being of the user’s own technique and the user’s nerves is much more important than the cost of paying for the matrix adjustment.
Checking the monitor for dead pixels: 2 ways to check it yourself
The monitor is an indispensable attribute of the computer user. Buying expensive equipment, everyone wants to get a durable tool with clear graphics and fine detail.
However, there are frustrations. incomprehensible points that DO NOT react to changes in screen color and are great annoying. What to do when a defect is found and is it possible to return the display if a warranty card has been issued. the answers are set out below.
before the purchase
If the resolution is obtained, you can choose one of the options for checking the monitor for dead pixels:
- visual inspection is an unreliable method, since it is difficult to determine “by eye” the existence of non-working components. If other methods are not available, it is recommended to bring a magnifying glass with you to help you better see every inch of the display;
- loading of contrasting monochromatic pictures from a previously prepared flash drive. The method quickly identifies such flaws, if they exist, they will certainly appear;
- application of verification software developments. Unmistakably indicate location and breakdown status.
Checking the monitor for dead pixels using the program can be done while at home or in the office. Even displays of the highest category often acquire such shortcomings over time, although before that they functioned without complaints. There are a lot of tools on the net that you can use for free. These include:
- DeadPixelTester. checks without installation;
- Is My Lcd Ok. launched with the function keys F;
- Monteon. a resource without an installation file in an online format;
- VanityMonitorTest. no need to download, but you need a flash installer.
Which case is NOT guaranteed
If a non-working or stuck element is found on a new device under warranty, this does not mean that it will be accepted for exchange or refunded. The ISO13406-2 standard defines the minimum threshold for damaged dot formations, depending on the display class.
How to remove a dead pixel on the monitor
Before proceeding with the elimination of the error, it is important to understand why micro-squares fall out of order. A pixel is the smallest particle of red, blue and green colors. THESE segments form a graphic that covers the entire spectrum.
The illuminated components work on a transistor component that controls the color rendering process. If a component is broken, the segment goes out and gets black on the screen. Such a pixel cannot be restored in any way. Consoles that it is barely noticeable and, in principle, not annoying.
If the point is white or second color. not all is lost.
What is a dead pixel on the monitor
This is a bright, or, conversely, NOT an illuminating point, which becomes visible when the background spectra change. By the way, not only whole segments are damaged, but also their components, in this case they shine in red and a second color. they appear
- for various reasons, the Fundamental ones are:
- physical influence. strong pressing on the screen, hit or other force damage;
- unfavorable environment. high humidity, heat, sudden temperature changes;
- fatty fumes and other conditions unusual for technology.
How to check the monitor for dead pixels
This procedure is easy to perform at home or contact a master. Since the process does not require special knowledge in computer technology, it is not worth spending on service, it is easy to identify the defect yourself.
How many dead pixels are allowed: table
To understand how effective treatment will be, it is important to understand the severity of the problem:
- 1st. a luminous snow-white point, easily detected on a dark background, it is possible to restore.
- 2nd. extinct pix, visible in the shades of the light spectrum. “Recovery” is impossible.
- 3rd. the “hovering” particle is highlighted in a varied palette, from blue to poisonous red. but there is a chance to use it.
In the case when it is not possible to use utilities, it is worth trying to act mechanically. Among the methods Recommended:
- circular movements of a massaging nature to the area of the point. To do this, the monitor is turned off, and to find the right place. the area is marked with an erasable marker. Be sure to use a soft tool, such as a cotton swab;
- disconnecting the monitor from the network for 5-6 days in order to remove static and accumulated voltage from the transistors. Such a reboot will help to activate the performance of the stuck subpixels.
Broken pixels appear on both new and long-running monitors. They deteriorate singly and in groups, creating squares, stripes and other geometry. You can identify the malfunction yourself if you use the methods mentioned in the article, and you can get rid of only two of the three types of points. There is a high probability that the problem may return over time, and it is not a fact that the next time it will be possible to fix it in the same way.
To make the purchase of a monitor a joy, it should be tested immediately. This is the interest of the client himself. Factory and current defects in the work of pixels do not always fall under the guaranteed return, since the manufacturer has the right to refer to the current threshold for the minimum value of damaged particles.
