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.

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);
