LG's program for replacing monitors with defective pixels is called Zero Bright Dot. Its essence is that if at least one bright dot appears on a monitor of the premium series Lx40, Lx60, Lx70, Lx80 or Mx80, then such a monitor is subject to warranty repair - replacing the matrix or replacing the monitor (the decision is made by the service center). Moreover this rule valid throughout the entire warranty period for LG monitors, i.e. three years.
For all other models there are tolerances for defective points (see slide). Here they are stricter than the generally accepted ISO 13406-2 standard, and guarantee LG monitor users a higher quality product than competitors. Information on tolerances is available in printed and in electronic format at all sellers and retail stores, which sell displays manufactured by LG Electronics.
The program is valid for three years from the date of purchase of the monitor, i.e. during the entire warranty period. This applies to premium series monitors, in which not a single bright point is allowed, and to all other monitors according to LG rules.
If defective pixels are detected, the buyer can contact any of more than 100 authorized LG service centers in our country. The warranty repair periods for LG products correspond to those specified in the Law of Ukraine “On the Protection of Consumer Rights” - i.e., a maximum of 14 days from the date of the buyer’s request. As a rule, LG Electronics service centers carry out repairs in a shorter time - within a few days.
"Ingress"
Alexey Kichaty, product manager of Ingress LLC
As such, neither NEC Display Solutions nor BenQ have a marketing program regarding defective pixels. But since the problem of dead pixels is very important when selling monitors, our company has a flexible approach to solving it in each specific case. This could be either a monitor replacement or an additional discount. Fortunately, due to the high quality of LCD panels, such cases are very rare.
All NEC and BenQ monitors comply ISO standard 13406-2 for LCD panels, which describes the acceptable number and location of defective pixels and subpixels on a panel. Briefly about pixels and subpixels, which are very often confused - how to distinguish them? All LCD panels are made up of pixels, each with three sub-pixels (red, green, blue). There are three types of problems:
- constantly glowing pixels (white) are white dots on all colors;
- “dead” pixels (black) – black dots on all colors;
- defective red, blue and green subpixels - when one of the pixel elements does not work, the dot can change color depending on the background, the formation of the required color is disrupted.
According to this classification, all monitors are divided into four classes. In the first, not a single problematic pixel or subpixel is allowed, and if the manufacturer rates its product 1st class, then the presence of even one point is the basis for a service replacement of the monitor. But class 1 panels are very rare.
All NEC and BenQ monitors are Class 2 compliant. According to the standard, the presence of either 2 problematic pixels of types 1 and 2, or up to 5 problematic subpixels per 1 million pixels is allowed. Classes 3 and 4 of panels allow for an even greater number of problematic pixels and subpixels.
Since a “flexible” approach to resolving such issues has already been mentioned, our only condition is that the buyer contacts us within a week; after this period, all “pixel” problems are resolved only through service centers. One of the features of LCD matrices is that if problem pixels are absent when the monitor is first turned on and do not appear within an hour (when the panel warms up), then the likelihood of them appearing in the future without physical impact on the matrix is very small.
It is worth noting that we try to resolve similar issues regarding all models of NEC and BenQ monitors. The buyer can contact the seller within a week or upon completion of the examination period for the admissibility of the number and location of points, which is carried out service center. Technical examination does not take much time either with us or at the service center: there are special tables of acceptable defects, and a conclusion can be issued within one hour. If the inspection was carried out by a service center, then if the acceptable number of points is exceeded, it issues a certificate indicating the need to replace the product, upon presentation of which the buyer can receive a new monitor on the same day.
ViewSonic
Andrey Lunev, regional service manager for the CIS, ViewSonic Europe Limited
A new program aimed at familiarizing consumers with the terms of warranty exchange of LCD monitors in case of detection of defective pixels is called Zero Bright Dot for professional VP series monitors.
Given that the percentage of our monitors with defective pixels is close to zero, ViewSonic provides an additional quality guarantee for our VP Series models.
Our displays meet the requirements of the international standard ISO13406-2 (class 2). Striving to better meet customer needs, ViewSonic delivers the highest quality products in the industry. Therefore, our LCD displays usually have very few dead pixels. For example, an 18-inch SXGA (1280x1024) display contains almost 4 million subpixels, and if any particular example has seven defective pixels, then this is an extremely small fraction (only 0.00018%) of the total number of subpixels:
(1280 pixels horizontal)×(1024 pixels vertical)×(3 subpixels per pixel) = 3,932,160 subpixels
7 defective subpixels / 3,932,160 subpixels×100% = 0.00018%
In order to guarantee highest quality of its displays, ViewSonic sets a maximum acceptable number of defective pixels. The company accepted following criteria Determination of the number of defective pixels in relation to its three-year warranty (this policy applies to all ViewSonic LCD displays for the entire warranty period):
For 14- and 15-inch LCDs, ViewSonic sets the limit at 4 non-bombing subpixels, 4 non-bombing subpixels, or a combination of 4 subpixels of both.
For 17- to 19-inch LCDs, ViewSonic sets the limit at 7 non-bombing subpixels, 7 non-bombing subpixels, or a combination of 7 subpixels of both.
For 20-inch and larger LCDs, ViewSonic sets the limit at 10 non-bombing subpixels, 10 non-bombing subpixels, or a combination of 10 subpixels of both. No defective pixels are allowed.
Within 15 days from the date of purchase, the buyer can exchange the monitor even if dark background Only one subpixel is constantly lit. The limited return period is established because 99% of image defects appear after one normal thermal cycle (that is, after the display has been in use, then turned off and on again - heating, cooling, heating).
The introduction of the Zero Bright Dot guarantee creates an additional advantage for the VP series. If defective pixels are detected, the buyer must contact the service center. Technical examination and warranty exchange usually take one day.
Samsung
Andrey Leiko, customer support manager
The terms of the Zero Bright Dot promotion provide the following: Samsung Electronics undertakes to replace the monitor to the user if at least one bright defective subpixel (red, green, blue or white) is detected within two weeks from the date of purchase of the Samsung TFT monitor (models SyncMaster 172X, 173P, 173P+, 193P, 193P+).
There are two types of defective subpixels: bright and dark. If you display a white field on the screen and subpixels are visible on it, then these are dark. If subpixels are visible on a black field (white, red, green or blue), then they are light. When a subpixel turns out to be partially dark or luminous, it is also considered defective and is taken into account in the specification. For example, for 17" Samsung monitors(except for Zero Bright Dot Warranty models) it is acceptable to have 3 bright and 5 dark subpixels, but not more than 5 in total. However, even the presence of only 3 bright subpixels on the monitor screen may be considered unacceptable by Samsung if they are located at a distance of less than 15 mm from each other. An opinion on the acceptability of defective subpixels is given by any authorized Samsung service center from our most extensive network (there are more than two dozen of them in Kyiv alone).
The Zero Bright Dot guarantee provides the ability to replace the monitor (SyncMaster 172X, 173P, 173P+, 193P, 193P+ models) within 14 days from the date of purchase if at least one bright subpixel is detected. Samsung's usual three-year warranty continues.
In case of detection of defective pixels falling under the terms of the Zero Bright Dot Warranty, the buyer can contact either the seller or an authorized Samsung service center. A technical report can be issued immediately or within any period of up to 14 days from the moment the device arrives at the service center, it depends on the complexity of the procedure for determining the defect.
TV production technologies are constantly evolving. It's safe to say that we live in the generation of plasma and LCD panels. The well-known bulky TVs with cathode ray tubes went out of fashion. And this is not surprising, because modern TVs are far ahead of their predecessors, both in performance and in build quality and a number of other parameters.
But as they say, every technique has its drawbacks. In this article we will discuss an important issue regarding dead pixels on plasma and LCD TVs.
What is a dead pixel on a TV?
To put it simply, the image on a television panel is formed from a huge number of colored dots called pixels. The principle of operation of a plasma TV is of course different from the principle of operation of an LCD TV, but the structure of the image in both cases is the same. The pixels change their color in a given way, resulting in the desired picture.
Each pixel has its own strict structure. Pixels consist of three subpixels of different colors. Red, green and blue have different intensities and can create any color. Most modern TVs use an active matrix. In this case, each individual pixel is controlled by a special transistor. If a transistor fails, the corresponding pixel stops functioning - this is called a dead pixel.
This pixel looks like a black dot on the screen. A dead pixel of this type can only be restored by replacing a faulty or malfunctioning transistor. This method is not suitable for ordinary users.
There is another type of dead pixel - stuck pixel. A characteristic feature of such a pixel is the fact that it looks like a bright spot on the TV matrix. This is because the subpixel gets stuck in one position and only lights up in one color. Pixel defects of this type can be eliminated at home using a specialized software or through the use of physical manipulation. The question inevitably arises: why bother repairing dead pixels on a TV yourself if there is warranty service?
The answer is very simple. The production of panels without dead pixels is almost impossible; if you set up production that does not allow such a defect, the cost of TVs will increase significantly. Therefore, TV manufacturers have adopted specific standards according to which a certain amount of Dead pixels on the matrix are not defective and cannot be repaired. There is a generally accepted state standard ISO-13406. According to this standard, there are three main types of dead pixels, and all panels can be divided into 4 classes. So the types of dead pixels:
1. There is a white pixel on a dark background.
2. There is a black pixel on a light background.
3 . The pixel is constantly lit in one color (problem with subpixels).
First class panels do not allow any dead pixels. If there is at least one dead pixel, then you have the right to warranty replacement panels.
Panels of the second class allow the presence of two defects of the first and second types, as well as five defects of the third type. It would be appropriate to say that such panels are the most common on the modern market. If your new TV has a second-class matrix and a couple of dead pixels, then this is not a defect and do not expect a replacement.
Panels of the third class allow the presence of five defects of the first type, fifteen dead pixels of the second type and 50 of the third.
And finally, the fourth class has the largest range: 50, 150 and 500 dead pixels of the first, second and third types, respectively.
Check your TV screen for dead pixels
Determining the presence of dead pixels on a TV matrix can be difficult. In-store TVs display bright images, making it difficult to spot a pixel defect by eye. But if you take this issue seriously, you can still protect yourself from a low-quality matrix.
Of course, there are stores that provide paid services to check the TV panel for dead pixels. But there are also free methods. In order to check the TV matrix for the presence of dead pixels, it is necessary to display images of a single color on the screen one by one.
For example, if you are looking for black dots, then display White background. If you are looking for a white point, then display a black background, and so on. If you carefully view the entire screen, the dead pixel will be visible to the naked eye. The method is painstaking, but reliable. As they say, everything is in your hands.
There are special generators that display images of the corresponding color on the screen. The same can be done by loading pictures of the corresponding colors prepared in Painte from a flash drive onto the TV. A similar function can be built into the TV model you choose. Ask the seller about this.
A more functional way is to check for dead pixels using programs. But for this you need to first or. Download the appropriate testing program onto your computer and search for defects. I would like to highlight the functional utility Nokia Monitor Test, which will help detect defects and dead pixels on the TV panel.
Install Nokia Monitor Test on your computer. Launch the program and select the color check mode. Alternately switch the colors with the left mouse button and analyze the matrix. You can write the program to a disk or flash drive before visiting the store and ask a consultant to check it. If you are lucky, you will not find any defects. What to do if there are dead pixels? Read on.
Repairing dead pixels on TV
The sad news is that black pixels (the transistor burns out) cannot be restored with your own efforts. We will talk about restoring stuck pixels. There are several methods, they will not be 100% effective, but it is always worth a try.
The first method is to physically impact the malfunctioning pixels. Turn off the TV, and using a cotton swab, very gently press on the area where the dead pixel was detected. A few minutes and stop, turn on the TV and evaluate the result. Repeat the procedure if necessary. This method is intended for LCD panels, mechanical impact can move the liquid crystal and the pixel will begin to function normally. Do not use sharp or cutting objects as this will further damage the matrix.
More gentle and safe way, this is the use of specialized programs. One of these is located at jscreenfix.com/basic.php. According to the developers of the utility, after 20-30 minutes of using it, the problem with stuck pixels is resolved. If there is no result, repeat the procedure after a few hours. What does the miracle program do, you ask? This program quickly changes colors around the broken pixel, which allows you to programmatically solve the problem.
Go to the above site and click Launch. When you launch the program, you will see a window with flickering pixels. Point it at the area of defects and wait for the results. This program may require the purchase of a license. But there are other similar utilities.
conclusions
In this voluminous article, we examined all the questions regarding dead pixels on a TV. If you do not want to solve the problem with pixels at home, then after discovering them, it is better to turn to specialized services. Good luck to you, we hope the article was useful.
Dead pixels are one of the most pressing issues, often becoming the reason for heated showdowns with suppliers of LCD monitors, tablets and smartphones. Managers of fashionable stores often hasten to disown this problem, citing the regulations of official manufacturers. We will focus on what “broken” pixels are and how to deal with them one-on-one in this article.
Checking and treating dead pixels
Monitor, like Personal Computer, we buy for more than one year. But, unlike a PC, which can always be upgraded if desired, there is no way to improve the quality of the image using hardware. That is why, when assessing the functionality and picture quality of a potential candidate for the position of a home monitor, we approach the issue of choosing a model extremely responsibly, investing in the new product to the maximum and for a long time.
And now, all the accents have finally been set, a brand new monitor has been purchased and connected, it shows all the signs of life, it pleases the eye with image quality and color depth. You are, of course, happy with the purchase and everything would be fine, but something confuses you, distracts your attention and prevents you from perceiving the picture in all its fullness and entertainment. The gaze every now and then slides to a dark, light or colored point, which retains its color regardless of the image being broadcast. Well, introduce yourself, gentlemen, you are extremely lucky: before you is His Majesty “Broken Pixel”!
Problem
The image that we see and perceive on an LCD monitor as a single whole is actually formed from many clusters of dots called “pixels”. In turn, the entirety color range can be achieved using only three subpixels - red, blue and green. In models of LCD monitors with an active matrix, each pixel is assigned an individual thin film transistor (TFT), damage to which will appear on the screen as a black inactive dot, which is called a “broken” pixel. And in this case, the problem can only be solved by replacing the transistor in the laboratory and, alas, there is no alternative here.
If you observe a light point on a dark background, do not rush to despair! Quite often, the reason for the appearance of broken subpixels is their “stuck” in some intermediate position, which outwardly manifests itself in the absence of their reaction to a changing picture. You can solve the problem at home, without fear of damaging the monitor, using software, or by performing some physical manipulations.
Why do it yourself if the monitor is under warranty?
An absolutely normal question that everyone asks themselves who has already become familiar with our problem, but is not yet familiar with the likely reaction of the store. It turns out that even despite the warranty obligations of the service, nuances and disagreements are very likely.
Defective pixels? - Complain to the Stockholm Arbitration Court!
The real reason for the dispute is the manufacturers themselves, who have officially established a tolerance for a certain number of “allowed” dead pixels on monitors of the relevant standards - ISO-13406 regulations.
In accordance with accepted tolerances, monitors are divided into 4 classes:
1st class - dead pixels are practically excluded, warranty repair and replacement in case of detection is mandatory and carried out immediately;
Class 2 is the most common option, allowing for the presence of 2 defects of types I and II;
3rd grade - budget models, allowing the presence of 5 dead pixels of type I, 15 - type II, 50 - type III.
4th grade - monitors Low quality, allowing the presence of 50, 150 and up to 500 (!) defects of type I, II and III, respectively.
Note:
Type I - white pixel visible on a black background;
Type II - black pixel on a white background;
III type - red, blue, green pixels.
It becomes clear that despite the warranty, the annoying single white pixel in the center of the screen of a class 2 monitor remains your problem, and The best way to prevent such a situation - connect and test the display before payment or within the period available for exchange in accordance with the consumer protection law.
Checking the monitor
A visual assessment of the picture quality in the interior often does not allow one to draw an unambiguous conclusion about the presence of broken subpixels, much less determine the presence of moire, assess the readability of moving text, the response speed of the matrix and other significant parameters. And why, if it is much more reliable, simpler and more effective to check the monitor using specialized utilities, which will allow you to receive all the data in full, and most importantly, on time. Good choice free programs, allowing us to achieve our goal without spending any money, today is off the charts.

Thus, by installing this miniature (68kb) utility, you get the opportunity to simulate on the display the conditions under which hidden monitor problems will appear explicitly.
Platform: Windows. The interface is in English.
All of the programs listed are absolutely free and do not require registration in the registry.
The patient is probably alive...
So, software diagnostics allowed us to accurately determine the presence, location and type of dead pixels. Let's assume that we are lucky, and the pixels that we see on our screen are among the “stuck” ones, that is, light ones.
Paradoxically, it is often possible to carry out an operation to “reset” the pixel into its place by massaging the injured area with circular movements. This should be done not with your finger or with hard and sharp objects, but with a cotton-tipped swab, gently, slowly, with the monitor turned off. And in order not to “miss”, mark the dead pixels detected by the program before you turn off the monitor.
Manual therapy or how to get rid of frozen pixels surgically
Repeat the rotational movements for two to three minutes, then start the monitor and appreciate the fruits of your labors. If there are none, repeat everything again. The method does not provide a 100% guarantee, but it increases the chances of getting rid of the problem many times over.
“Civilized” way
Unlike the first method, which requires some caution on your part, the alternative is programmatic method completely safe. The simplest way- use a specialized program that deals with stuck pixels in a few minutes. You can launch it directly from the site by following the link: www.jscreenfix.com/basic.php and clicking on the Launch ScreenFix button at the bottom of the page.
After starting the program, you will see a window with flickering pixels, which must be aligned with problem area. During the “shaking” process, the colors of individual pixels change at an increased speed, which at some stage allows the stuck culprit to “unstick” and return to working condition.
Jscreenfix program at work
As practice shows, in 20 minutes of work the program deals with the vast majority of problem areas. If the result is not achieved, the developers recommend leaving the computer in this mode for 5-10 hours. Note that cured pixels do not acquire immunity and with the onset of summer heat they have every chance of sticking again. In this case, it is recommended to repeat the course of treatment.
Well, now you are armed with the knowledge, and if necessary, you can deal with stuck pixels without the help of computer gurus and intractable managers. Better yet, use the acquired knowledge when purchasing by testing the monitor of one of the programs at the store counter, then the problem of “stuck” and fatal black pixels can be avoided! Add tags
Summer has begun, heat and new jokes. I have a one-room apartment and, guess what, I decided to put a second computer in the kitchen with a 19-inch TFT monitor! What does summer and dead pixels have to do with it? And here's what it has to do with it. 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, on the contrary, dots or parts of a dot (subpixels) on the monitor that are not working. If a 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 type of dead pixels, but it is practically impossible to treat.
The most common dead subpixels are when a bright red, blue, green, yellow, turquoise or purple dot is constantly glowing. They are also called “stuck pixels”. If such a pixel appears in a visible place, it is very annoying, especially the red one :) If all three subpixels are faulty at once, then a white dot will glow on the screen.
By the way, defective pixels They can either appear or disappear. On my main monitor from the moment I purchased it, there were three multi-colored dots in the middle of the screen. I either didn’t notice them when I bought them, or they already appeared at home, I don’t know. But I didn’t bother about this, because... they were absolutely invisible to the eye unless you looked closely. In 4 years of working with this monitor, I have 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 an 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 whether these pixels can be removed in a new way. I started checking - but they weren’t there! They all went somewhere in formation :)
Programs for restoring dead pixels
There is no need to talk about high-tech methods used only in laboratories. 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.
Restoration occurs due to the rapid change of 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 require a different amount of time; you will have to experiment if you can’t quickly remove damaged pixels. Experiments mean changing the speed of color changes and the running time of the program.
The restored pixel may become stuck again after some time, especially in hot weather. Then the treatment process will need to be repeated. In some cases, such a pixel cannot be completely cured.
UndeadPixel will suit most
Go to the official website and download the program installer. I recommend the installation version, not the portable version.
In the main window of the program, you are prompted to first find dead pixels by filling the screen with solid colors: red, lime, blue, white, black and yellow. Different dead pixels will be visible on different backgrounds. If you already know where your pixels are, then go straight to recovery.
UDPixel works like this: a square appears in which the colors quickly change, i.e. there is a pixel restoration algorithm working there, and we need to move this square to the problem area of the screen. In the “Undead pixel” section you need to set the following 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 1x1 or 5x5 pixels. Since it is very difficult to set a 1x1 square to exactly 1 pixel, a 5x5 area is suitable for restoring even one pixel
- Flash interval — pixel update speed according to the algorithm. The shorter the time, the faster speed. Maximum speed at 3 ms.
Click Start and move the flickering square(s) to the defective areas, watch the video below. When the pixel starts blinking, then this is already a bid for victory, just leave it for a longer time. If everything remains unchanged, then select the maximum speed and wait until the pixel disappears. In worst cases it can take 10 hours, there is no point in waiting any longer.
The peculiarity of UDPixel is that during pixel restoration you can continue to work if the squares are not large and do not interfere.
JScreenFix for browser
This is not a program, but just a website, free service in 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 click the “Launch JScreenFix” button. The JScreenFix script restores dead pixels in the same way as UDPixel, only without the ability to change parameters, and you won’t be able to work on the computer at this time.
You need to move the iridescent square to the problem pixels, and if they are outside the browser window, then switch to full screen mode using the green button. Look at the video how Undead Pixel and JScreenFix work:
The manufacturers of these programs recommend doing preventative maintenance on your monitor, occasionally starting the “recovery process.” I don’t know how justified it is to spend your attention on this, but for plasma panels it can be really useful.
Bad Crystal - all-in-one combine
On the website you can both download the program and buy it. The free version runs for 30 days in limited functionality mode, which does not support more advanced technologies. You can find a version without restrictions on the Internet 😉
The program begins by selecting a device: computer screen, mobile phone, game console or plasma panel.
For mobile phones and game consoles, a video file is generated at the selected resolution. You will need to play it in repeat mode on your smartphone. For the TV, you can burn a DVD or flash drive with ready video, or run in “Full Screen” mode.
If you have a regular monitor or laptop, select “Computer Monitor”. To display extra menu you need to move the mouse to the top of the window. There are four modes available here: Common Clearing (CCM), System Modified (SMF), Complex Force (CFV), Personal Protection (PPM). IN free version Only CCM and PPM work. The remaining two modes should provide a higher percentage of restored pixels. By default, CCM is selected.
Click “Launch” and move the window to the area of dead pixels. We wait 5-10 minutes and check. If the point remains, then increase the speed using the “Speed Up” button, which appears if you move the mouse to it, and wait another 10-15 minutes.
The developers claim that their algorithms allow not only to treat pixels, but also to eliminate spots on the screen and. But this is the case when these are simply accumulations of pixels that are not working correctly. Watch the video:
Next, to prevent the pixels from getting stuck again, it is recommended to turn on auto mode prevention – PPM. In this mode, the colors on the monitor change over time. The process starts 2-3 times a month when no one is working at the computer.
Mechanical method
I have not tried this method, but I have seen many reviews in its favor. If the programs couldn’t cope, then it’s time to massage the monitor :) Exactly. Take the ear stick and start massaging on the spot dead pixel. You just don’t press very hard, but so that streaks appear, and massage the affected area. The case requires perseverance, as it may take from 10 to 30 minutes of work.
If it works - hooray! I congratulate you, you can “polish” this matter with Bad Crystal. And if the pixel stubbornly refuses to recover, then you can try running the program and at the same time massaging the area for 15 minutes, then leave the program running for 10 hours.
I hope that the article was very useful to you. Your friends will be very grateful if you share this information using the buttons social networks under the article.
