Unfortunately, this can be time-consuming and expensive, especially if you’ve invested in one of the highest-rated OLED TVs and/or large models like the top 70-inch TV.

While most new TVs sold are smart TVs, you can still buy what is referred to now as “dumb TVs.” If you want a TV without apps and an internet connection, this is the TV for you. If that interests you, check out these top-rated dumb TVs. But keep in mind, unlike most new TVs, dumb TVs will usually be smaller, like a 24-inch size TV, for example. Regardless if the TV is smart or dumb, it can develop black spots, however. Fortunately, fixing a black spot is relatively easy. As a result, we have compiled a guide on how to fix a black spot on a TV screen.

If you have the best outdoor TV, be sure to keep up with maintenance and regularly clean it.

Manufacturer defect: Black spots will appear due to a violation of the assembly. They don’t appear immediately and often lead to damage to the display matrix. A warranty usually covers black spots caused by manufacturer defects.

Stuck Pixel: A stuck pixel is a pixel on the TV display that cannot change color. Display pixels are designed to change color depending on the image projected on display. When the color doesn’t change, it’s called a stuck pixel.

Dead pixel: It’s pretty different from a stuck pixel but often gets confused for one. While a stuck pixel will light up when the TV is turned on but does not change color, a dead pixel doesn’t light up at all. This is because all of their sub-pixels are turned off permanently, and since they don’t light up, they look like black spots on the TV screen. You can read our article on how to fix dead pixels on a TV to learn more about dead pixels.

Fixing black spots on your TV screen is quite simple.First, turn off your television and unplug it from the power source for a few hours. Sometimes, turning off the power on your TV will force the stuck pixel to become unstuck when you finally plug your TV back to the mains.

Next, verify that the black spot issues aren’t caused by any devices plugged into your TV, like a console or cable box. Remove all cables connecting your TV to components, and then plug them back in. Sometimes, loose connections cause distorted images that look like dead pixels.

If a black spot is still visible, contact your manufacturer or repair shop for repair service. Depending on the time and nature of the black spot, The TV manufacturer might cover the repair under warranty. You can also try the clouding LED TV fix, which solves the black spot problem common among new TVs but often disappears as time passes.

With an LCD TV you can watch your favorite movies, cartoons, and series in excellent quality with high definition and good sound. However, owners of LCD monitors may encounter the problem of dark spots appearing on the screen. Let’s take a closer look at the reasons for their appearance and what are the best solutions to repair them.

So What Causes Dark Spots on TV Screen?Dark (black) spots on LCD TVs are typically caused by either debris or superficial dirt, a dead pixel, or a stuck pixel. Of all these problems, the easiest problem to fix is debris or superficial dirt. On the contrary, stuck pixels are harder to fix, while dead pixels are the hardest problem to fix.

It is very often, that dark spots appear on LCD TV screens, including popular brands such as Samsung, Sony, LG, and others. They can be localized in one corner, centered, or in several places at once.

Spots do not disappear when switching channels. Even when your TV is off, you can notice that glare is visible in their place. Moreover, blackouts can be not only black or dark gray but also white or colored. This most likely indicates the color errors or other problems.

Manufacturing defects. It is quite rare and manifests itself immediately. The reason is a violation of the assembly technology, leading to damage to the display matrix. The specialists of the warranty service center should eliminate such a malfunction free of charge. And in order not to buy a bad TV, you need to carefully examine the equipment in the store.

Mechanical damage. An especially common reason is when there are children in the house playing with a ball in the apartment. A strong blow or pressure will stain the CRT. Broken pixels first appear in the affected area, then spread across the screen.

Ingress of moisture or air under the protective glass. The reason is poor transportation or improper care. Do not wipe the monitor with water or a heavily dampened cloth.

The effect of high temperature. The presence of a heat source near the device leads to various malfunctions, including the appearance of yellow spots due to the delamination of the matrix.

Dust getting under the case. If you take care of household appliances incorrectly, one small black dot can develop into a large dark spot, which only the masters of the SC (service center) can remove.

If the black spots on your LCD TV screen disappear, the cause was most likely a software failure. In such a situation, it is not necessary to disassemble or repair the device in the service. If the malfunction remains, it is better to contact a professional to repair an expensive modern TV.

One of the reasons for the appearance of spots in the external adhesion of dirt, dust. In such a situation, it is not necessary to disassemble the equipment or reboot it. It is enough to wash the screen surface. For this:

If a defect appears due to water ingress, rinse the matrix. This requires a special detergent. Running water is not suitable. It contains a large number of invisible impurities, abrasive particles that will settle on the matrix and make the situation even worse.

Cleaning should be done in a well-ventilated area with good ventilation to remove dark spots from the TV matrix. It is advisable to turn on a humidifier, if available. Use soft cotton gloves to clean.

If you wish, you can carry out the replacement yourself if you have the skills to work with household television appliances. The repair instructions are as follows:

Important! If the TV is still under warranty, you do not need to disassemble it yourself. After any of your interventions, the warranty card will expire. And the repairs will be carried out for you free of charge or with a big discount and at the service center.

Rarely wiping the surface from dirt and dust leads to the ingress of microparticles on the matrix. Over time, a large dark spot is born from a small black dot. With the following actions you can save your TV from manifestations:

If the dark spots have not disappeared after all the manipulations, the Sony, Samsung, or any other manufacturer’sTV must be carried to the workshop for a full diagnosis and repair.

If a dark (black) spot appears due to moisture or dust, you can easily fix this problem by yourself. If on the other hand streaks appeared due to mechanical stress or strong exposure to high temperatures, which in most cases led to matrix delamination or failure of loops, then it is necessary to carry that equipment to the workshop.

In most cases it takes from 1 to 5 working days to repair and remove dark spots on a TV screen, depending on the workload of the wizard and the availability of parts in the service. The cost of repairs depends on the degree of damage and the price of spare parts.

Proper care of household appliances is the key to their correct operation for a long time. To avoid the appearance of dark spots, streaks on the screen of a plasma, liquid crystal TV, follow these recommendations:

Do not overheat the equipment. TVs can work around the clock, but this has a bad effect on their performance, color rendition, and image playback speed.

Taking care of your LCD or plasma TV in this way will save you from the appearance of dark spots on the screen. Try to avoid mechanical damage. Explain to the children that technology is not a toy. And enjoy digital TV for years on end.

Light, colored spots and streaks are removed by other methods. General repair method only in cases with software failure. Therefore, if any screen defects appear, just try to completely restart the equipment and reset the router to factory settings.

The panel’s pixels deteriorate and form memories for the colors they are displaying. Only those colors will start to appear on your television, creating a shadow of the still image long after you delete it. Never leave a still image on your TV for longer than 30 minutes to avoid this.

Dark (black) spots on LCD TVs are typically caused by either debris or superficial dirt, a dead pixel, or a stuck pixel. Of all these problems, the easiest problem to fix is debris or superficial dirt. On the contrary, stuck pixels are harder to fix, while dead pixels are the hardest problem to fix.

With an LCD TV, you can watch your favorite movies, cartoons, and series in excellent quality with high definition and good sound. However, owners of LCD monitors may encounter the problem of dark spots appearing on the screen. Let’s take a closer look at the reasons for their appearance and what are the best solutions to repair them and What causes a dark shadows on tv screen?

There are lots of reasons why you might be seeing shadows on your TV. To name a few, some of the most common reasons for shadowing on your tv, are burn-in, a poorly mounted TV, or faulty cables. Shadowing mostly occurs when you leave a still image on the screen for a long period of time. So, remember to always turn your tv off when no one is watching.

The truth is, there’s no easy way to fix shadows caused by burn-in, so the best idea is to prevent it. If you haven’t left a static image on the screen but you’re still seeing shadows, your TV may have some installation problems

How does burn-in happen? A Burn-in usually occurs when you leave a still image, for a long period of time, on your tv screen. Still, images such as a paused DVD or menu screen will be the main reason. The pixels inside the panel become damaged and develop a memory for the colors they are displaying. Your tv will begin to display only those colors, developing a shadow of the still image even after you remove the image.

You can prevent this by never leaving your TV on a still image for more than half an hour. It’s always a good idea just to be safe. Plasma TVs, with their phosphor technology, are more susceptible to burn-in than LCD TVs that use liquid-crystal technology, especially during the first 200 hours of use.

Another thing you can do is to avoid playing video games with static boxes, on plasma TVs if possible. What does this mean? These are the type of video games that show your power levels on the tv screen while playing. Playing for long hours at a time can cause the static boxes to burn-in.

Another thing is, to stay away from the black bars that appear when watching a widescreen movie. These days, most DVDs will give you an option to watch a full-screen version. If you do not have these options, change the TV’s aspect ratio through the picture menu until the black bars disappear. Black bars can leave shadows along the entire top and bottom of the TV screen.

Not a lot of people realize this, but if your tv is poorly mounted to a wall, shadowing may occur. Why does this happen? A poorly mounted tv’s wait will not always be shifted as it should and this may damage your TV’s pixels. Also, check whether TV is running in Power Saving Mode. Always follow the manufacturer’s instructions when mounting your television to a wall.

Are you someone that prefers to have your TV sit on the floor or on an entertainment center? There is no problem with this. With this said, always use the model’s mounting stand. Do not put the tv directly on the floor, the weight of the TV could compress lower pixels, causing a shadow effect at the bottom of the screen. Samsung tv screen

If you are watching tv on a 3-D television, you may see a shadow effect on the image. This especially happens if you aren’t sitting directly in front of the Samsung tv or any other TV. The 3-D technology used for many of these TVs still relies on the addition of special glasses to make the images clear with no shadowing.

Something that happens a lot with cable boxes and TVs, is incompatibility issues. This may lead to shadowing. This problem often presents when you are pairing up a newer TV with an older cable box. What you can do, is update your cable box’s firmware to try to resolve the problem; some cable providers make firmware updates available online, others will send updated firmware to you and some will send out a repair person to update the firmware.

Using an HDMI cable with external devices can sometimes result in a shadow image appearing on the LCD screen. This is often not because of the cable directly, but maybe because of the external device’s video output settings and the use of an HDMI cable, more than likely the LCD panel is going bad. You can try changing the output settings on the external device or using a different type of cable, such as a component cable.

A shadow image can appear on your tv screen if you are using an antenna to pull in channels over the air. This type of image appears when the antenna pulls in the same source from two different signals. How to get rid of this? Move the antenna around to different locations until the ghost image disappears, indicating that the antenna is now pulling the source in from one signal.

So, how do you prevent a dark shadow from appearing on your TV screen?Don’t keep a still image on your TV screen for more than 30 minutes; it might result in a “burn-in.”

Adhere to the preventive measure outlined above, and your TV will be miles off from developing a dark shadow fault. You’ll also be saving yourself the burden of trying to fix it. As they say, “it’s better to be safe than sorry.”

Before trying to disassemble an LCD TV or hand it over to a service center, it is worth excluding software failures that are possible with digital broadcasting. The test scheme for Samsung, Sony, and LG are common. There may be some nuances depending on the TV model. While watching TV with connected external devices and shadow appears only on specific channels, then the cause may be a broadcast signal.

One of the reasons for the appearance of spots in the external adhesion of dirt is dust. In such a situation, it is not necessary to disassemble the equipment or reboot it. It is enough to wash the screen surface. For this:Disconnect equipment. Disconnect it from the network to be sure.

If a defect appears due to water ingress, rinse the matrix. This requires a special detergent. Running water is not suitable. It contains a large number of invisible impurities and abrasive particles that will settle on the matrix and make the situation even worse.

If you wish, you can carry out the replacement yourself if you have the skills to work with household television appliances. The repair instructions are as follows:Prepare your work area and all necessary screwdrivers and other tools.

If the dark spots have not disappeared after all the manipulations, the Sony, Samsung, or any other manufacturer’sTV must be carried to the workshop for a full diagnosis and repair.

If a dark (black) spot appears due to moisture or dust, you can easily fix this problem by yourself. If on the other hand, streaks appeared due to mechanical stress or strong exposure to high temperatures, which in most cases led to matrix delamination or failure of loops, then it is necessary to carry that equipment to the workshop.

The service center specialist will carry out the repairs to your TV in the following sequence:Accept the equipment and write out a ticket that you have handed it over.

Proper care of household appliances is the key to their correct operation for a long time. To avoid the appearance of dark spots, or streaks on the screen of a plasma, liquid crystal TV, follow these recommendations:Place household appliances at a distance of 20 cm or more from a heat source: radiator battery, heater, and fireplace.

Do not overheat the equipment. TVs can work around the clock, but this has a bad effect on their performance, color rendition, and image playback speed.

Light, colored spots and streaks are removed by other methods. General repair method only in cases of software failure. Therefore, if any screen defects appear, just try to completely restart the equipment and reset the router to factory settings.

There are many reasons why dark black spots appear on the TV. But in most cases, their presence indicates damage to the matrix. And it doesn’t have to be mechanical. It is possible that the diffuser peeled off due to a manufacturing defect. And sometimes a dark spot on the TV can be eliminated by yourself! But in most cases, you have to seek help from an authorized service center of the manufacturer.

External polarizing filter . If it is missing, then instead of the image on the screen there will be only a dark gray background. Even if the layer of liquid crystals, as well as the backlight, function properly.

Also behind the matrix is an LED backlight. It is placed evenly over the entire diagonal plane of the TV. As a rule, this is an LED strip, where each element is connected in parallel (in some TVs it also happens in series, but this design is usually not used now).

failure of the video chip (graphic processor, which is responsible for processing the digital signal, converting it and outputting it to the liquid crystal matrix).

Experts say that they can be provoked either by mechanical damage to the TV (impact on the matrix), or sudden voltage drops (in particular, exceeding its permissible value, over 230 – 250 Volts). Therefore, if the current in the home electrical network is not stable, then it is recommended to connect the TV through an external voltage regulator – this really helps to extend the operational life of the equipment.

Indicates an open circuit supplying one of the liquid crystal zones. It is impossible to repair such a breakdown. There is also always a risk that such spots will increase in size over time. That is, with a probability of 95%, the matrix will soon become unusable. It should also be noted that operating a TV with a damaged mechanically damaged matrix is not a good idea. There is a possibility that there is a short circuit between the supply circuits of the matrix, which will also lead to the failure of the inverter, or even the GPU. Repairing such breakdowns is impractical. That is, in the future you will have to purchase a new TV to replace the old one.

Failure of the LED itself . That is, the semiconductor of which it consists, corny burned out. It is impossible to replace, in service centers they offer only a complete replacement of all LED-backlight strips. But this is a relatively inexpensive procedure.

Failure of the inverter, which is responsible for supplying current to the backlight . In this case, the LED may initially not work only in a certain zone (for example, in the upper left corner). But in the future, other lighting zones will definitely be de-energized.

It looks more like a blackout zone with a corresponding halo rather than a separate dark spot. But at the same time, if you shine a powerful flashlight on the darkened part, you will notice that the image is displayed normally on the liquid crystal matrix. It just doesn’t light up. You should not do something on your own, it is better to contact an authorized service center for help as soon as possible. It should also be noted that if the backlight is damaged, it can periodically recover on its own. But this is a short-term effect. It is only additional confirmation that there is a violation in the supply circuits of LED strips.

In principle, the causes of spots for almost all TVs are the same, since the structure of the matrix and the principle of displaying the image are similar. But there are a few exceptions:

On Samsung TVs with AMOLED matrices, dark spots may indicate matrix “burn-in”. There is no backlighting, as each pixel is technically an organic LED. At the same time, the spots look like an afterimage (they are often called “ghosts”).

Dark spots on the LG TV screen are sometimes the result of a software glitch! More precisely, because of the violation of the AVI and MPEG4 codec coding technology. In such cases, a banal firmware update using the built-in tools of the TV itself helps. With this problem, dark spots appear in different places every time you turn it on, without any cyclical order.

In very rare cases, dark spots disappear on their own over time. This happens if they appear due to delamination of the polarization layer with a slight overheating of the matrix. But this is about 0.5% of all cases. In other situations, a visit to the service center is required. And the faster, the better. How can the risk of stains be minimized? The following recommendations must be followed:

by any available means to level possible mechanical damage to the TV (for example, if there are small children in the house, then it is better to place the TV on the wall at a height of at least 1.5 – 1.7 meters);

While replacing the screen is the most effective way to restore a screen that’s no longer displaying the correct image, it can also be difficult and can damage the TV. If you’re not sure how to fix dead pixels, you can try some DIY methods and use a soft cloth to massage the screen of your television. Make sure you avoid rubbing the screen with your finger as that can scratch the screen and cause more dead pixels.

If you notice that your Samsung television’s picture quality is declining, you should get it repaired. While most manufacturers don’t cover dead pixels, some of them do. Some will only replace a television after it’s been under warranty for a certain amount of time. For brand-new devices, you might want to try exchanging your TV. If the dead pixels are caused by a malfunctioning transistor, contact the manufacturer of your television to see if you can get a replacement.

To fix a black spot on your Samsung TV, you should first unplug it from its power source. Leaving it unplugged for several hours should force the black pixel to become unstuck. Then, use a clean, dry microfiber cloth to wipe off the accumulated dirt on the screen. It could be caused by plugged-in devices or loose connections. A black spot could be a sign of a dead pixel.

Sometimes, dark spots appear on the TV screen for no apparent reason. These are often caused by dirt and debris on the screen. The most common cause is dirt, but there are other causes as well, including assembly violations that lead to display matrix damage.

There’s other rare event that occurs little often after turning on the TV, which consists of displaying a perfect image for around half a minute. Then, the whole image turns extremely dark and doesn’t come back until I turn off and on my TV.

This TV has a software check option, which apparently doesn’t work. After holding the on button for a few seconds with the TV off, it displays the message “Software file check failed, please unplug then plug the power cord back in, and try again.“ unplugging then plugging doesn’t allow me to do the software check.

When it comes to fixing a black or dark spot on a Samsung TV, there are several steps you should follow. First, examine the TV’s screen to see whether it is truly black or if it is partially or completely black. If the screen is completely black, the problem likely stems from the backlighting. If you can’t see any color, you can try adjusting the brightness or contrast levels. If none of these steps resolves the problem, you will need to reset your TV.

If you have never performed any TV repair before, you should not attempt to repair the screen yourself. The reason for this is that fixing the TV is difficult and requires disassembling the television’s case to find the problem. You might also end up damaging its warranty coverage or worse, damaging the TV further. For this reason, you should contact an expert technician. If this doesn’t work, you should try the second step.

If you’ve been watching TV and noticed a dark shadow, you’re probably wondering “What causes this dark shadow?” If so, you’re not alone. Samsung is notorious for having led issues. If you’ve had a similar problem with your TV, you can try to fix it yourself. To do so, simply use a blunt object to strike the outer edge of the TV. Make sure you don’t hit the screen.

If you can’t find the problem by using the remote control, try changing the picture settings on the TV. You can do this through the setup menu. If this does not work, try removing the power cord from the TV and wait about thirty seconds. If the problem persists, you may need to replace the screen or perform a factory reset. Otherwise, you should check with the manufacturer. If you can’t find an easy solution to this problem, here are a few things you can try.

If you’ve tried all these solutions and still don’t see a solution, try a soft reset. It will likely fix the problem, but you should first disconnect the power cord from the wall outlet. If you don’t see any change in the image quality after resetting, the video controller board could be causing the problem. If your Samsung TV’s screen is completely black, perform a soft reset to eliminate any unwanted dark shadow.

If you have noticed that your TV screen is starting to appear cloudy and dark, you may want to learn how to fix dark spots on Samsung TV. If you notice that your television is displaying a dark bar across the bottom, this problem is most likely caused by a problem with your signal or with your TV’s backlighting. To solve the problem, simply turn up the brightness of your Samsung TV. If the issue persists, you may want to reset the TV.

If this problem persists, you should contact Samsung technical support to get a solution. You can reach them via phone or online. The most common cause of a dark shadow on a Samsung TV screen is the HDMI cable. If the cable is in good condition, you can easily replace it. If this does not fix the issue, you can try a diagnostic tool. Alternatively, you can try a factory reset on your TV.

Do you have black patches or dark bars on the screen of your Samsung TV? Perhaps you’ve even had the problem of the entire screen being completely dark. Regardless, the best way to fix the problem is to perform a factory reset on your television. This step will remove any current settings, such as the volume and contrast levels, and allow your TV to reset internally. However, make sure to reload all applications and enter all user accounts and passwords before you attempt the process. If the issue persists, try the second technique.

If you’ve done all this, your TV screen is probably the culprit. If your TV screen is black, this could mean a defective screen. Depending on your TV model, this might require replacing the FPC cable or main board. You can also check your TV’s LVDS cable or running a self-diagnosis to determine what’s causing the problem. If none of these steps are working, consult a qualified technician.

If you have ever wondered what causes the dark shadow on your Samsung TV screen, you have come to the right place. This article will explain what to do if you have this issue. In the first instance, you should disconnect your TV from its power source and turn it off. Then, wipe down the screen and the body of the TV. You should also remove any other connected devices. Afterward, restart the TV and check if the problem has been solved.

If the black shadow issue is not solved, try to change the signal strength of your TV. This may lead to the dead pixels that are missing their ability to emit light for the television image. Sometimes, this issue appears as afterimages. However, you can fix the problem by adjusting the picture settings in the Settings menu or by going to Menu. If the issue persists, you can always turn off Power Saving Mode and turn on the energy-efficient mode.

If you’re wondering, “Why is half of my Samsung TV dark?” you’re not alone. Millions of Samsung TV owners are wondering the same thing. Many of these TVs are plagued with a problem known as light leakage. It happens because a small gap between the screen’s two parts is letting light out before it reaches your eyes. Often, this happens because dust and dirt accumulate around the screen’s parts, preventing them from closing properly when the TV is off.

To diagnose the cause of this problem, you need to first check the HDMI cable. If the cable is faulty, it may be causing the issue. If it’s the cable itself, the problem may be something else. Sometimes, the TV’s screen backlights are no longer working on the left side. If that’s the case, it’s time to replace the cable. If the cable is still intact, try removing any external devices that are connected to the TV.

The first step to fixing the problem is to determine the cause of the dark shadow on your screen. If the shadow appears on the screen after a certain period of time, it might be caused by your TV’s backlight. To determine this, try switching to a different input and then reconnect your television to see if it helps. If the problem persists, contact Samsung technical support to get a free replacement screen.

To test the image sensor, go into the setup menu and change it from Low to High. Then, check the image in the TV. If the black shadow still persists after switching the mode, then restart the television. Restarting it will also perform a soft reset of the system. Alternatively, you can also reset your TV to factory settings. This will help the TV’s display to be free from the shadow.

A poorly mounted TV may cause the shadow as it moves around. It may not be positioned correctly on the wall and may need to be installed on a stand. When it is on the floor, the weight of the TV can compress the lower pixels, causing the shadow. If you find this is the case, you may need to replace the LCD panel. If it’s not, you can always repair the TV by purchasing a new one.

A few ways to fix dead pixels on your Samsung TV can be tried, but the most effective method is to contact the manufacturer of your television. If you do it yourself, you risk damaging the television and voiding its warranty. Alternatively, you can use a scratch-free cloth to clean the screen. Make sure to only use light pressure, as pressing the dead pixel could scratch it and cause further dead pixels.

In general, a dead pixel means that a certain portion of the screen is not receiving enough power. This can be due to a number of factors, including a failed power connection. Because pixels require power to change color, if the power is cut, the pixel is black. Occasionally, a dead pixel can be caused by many different factors. Here are the most common ones. Listed below are some simple ways to fix dead pixels on Samsung TVs.

Scrubbing a pixel is another way to repair dead pixels. To do this, use a damp cloth on the dead pixel. Be sure to rub gently to prevent damaging the surrounding pixels. If you continue to damage the dead pixels, you risk invalidating the warranty of your TV. If you cannot do this yourself, contact the manufacturer of your Samsung TV for help. You may be able to get the problem fixed for free under the warranty.

LED-backlit LCD TVs typically come in one of two sub-types of panels: Vertical Alignment (VA) or In-Plane Switching (IPS). VA panels tend to have much high contrast ratios, and therefore better black uniformity. IPS panels, on the other hand, have worse contrast ratios and suffer from more backlight issues that can affect black uniformity, including "IPS glow", which is a kind of "glow" effect that can be seen in the corners of IPS screens.

LED-backlit LCD TVs are prone to black uniformity issues, but OLED TVs can produce virtually perfect blacks because their pixels are self-emitting, and therefore don"t have the same limitations caused by improper backlight implementation. That means they don"t suffer from clouding or flashlighting as LED TVs do.

Poorly designed backlight placement. The type of backlight and its position directly affects the uniformity of the screen. The worst uniformity can be found on edge-lit LED TVs, because the LEDs are only on the edge of the screen. Full-array LED TVs have good uniformity because their LEDs are spread out across the whole screen. Some edge-lit TVs have great uniformity. You can learn more about different backlights here.

Non-uniform frame pressure. Both the LCD screen and the diffuser layers are somewhat flexible. A slight difference in pressure on the frame of the television can change the uniformity of the picture. On some televisions, this can be fixed (see below).

Uneven lighting intensity. Sometimes, the intensity between two lighting components can vary in a set (for example, one LED could be slightly brighter than an LED next to it). This is less likely to happen with a brand new TV but can start appearing over time if some components age and degrade faster than others.

Flashlighting can sometimes be fixed on some televisions. If the flashlighting is caused by pressure from the TV"s frame, you can adjust it by slightly loosening or tightening the screws behind the edge of the screen. Some TVs don"t expose the screws, however, so this won"t always be possible. You should also keep in mind that a small change in the tightness of a screw can have a big impact on the uniformity of the screen, so be careful if ever you do try this step. While this can fix the issue, we don"t recommend it unless you know exactly what you"re doing, as it may cause more problems than it solves.

For clouding, there"s a pretty simple fix that—while not guaranteed—can have good results. Power on the TV and display a black image. This will allow you to see the lighter spots on the screen. Next, take a soft cloth and massage those brighter spots to improve the uniformity. You should only apply very gentle pressure, just barely touching the screen. You can also try a few different stroking patterns. If you are patient enough, this works surprisingly often, especially on edge-lit TVs, although you should be very careful to avoid damaging your screen.

Alternatively, you might consider returning or exchanging your television. Some models are more prone than others to having issues. Even within the same model, some units can have more uniformity issues than others because of slight variation in the manufacturing or shipping process. It can be worth trying to exchange it for the same model before going with an entirely different TV. Extreme cases of clouding are also covered under a TV"s warranty.

Backlight uniformity issues don"t increase over time unless a large amount of stress is put upon the panel (in the case of a big temperature swing, for instance, or if the TV is moved).

Sometimes, just letting the TV settle for a few days after unpacking it can solve the issue. This is especially true if the TV is laid on the side during shipping/moving.

Black uniformity refers to how evenly a TV can display black across the screen, especially when displaying a bright object over a dark background. It’s important when watching dark scenes in a dark room, and while most people shouldn’t notice black uniformity issues like flashlighting and clouding, they can become more apparent when the issues are especially bad. You won’t need to worry about these problems in rooms with lights on, though. For each TV, we take a photo of a black frame to capture the black uniformity, and then we calculate the color values of the pixels to find the standard deviation of the uniformity. We then do the same with local dimming enabled.

You may be able to remove flashlighting (to some degree) by tightening the screws of the TV’s frame. This can have pretty dramatic effects on the picture, though, so you should be very careful when attempting this. For clouding, gently massaging problem areas with a soft cloth often does a good job of fixing bad uniformity. In the end, the safest bet may be to simply return or exchange your TV if you can, since uniformity varies between individual units.
