You have discovered a black spot on your laptop screen, and you are not alone! Finding a black mark on your LCD can be disheartening, but there are steps you can take to get rid of it. So, if you are here to know how to fix black spots on a laptop, do not skip any part of this article and read until the end.
The black spots are just surface blemishes that appear when dirt or other particles lie on the glass of your screen or due to some defects with the LCD pixels. They are not cracks or tears that may cause the display to fail in the near future, and it’s certainly not an indication of broken glass. Although these can easily be fixed, it is crucial to have a proper understanding of what causes the spots so you can take measures to prevent them from appearing again in the future.
A laptop or LCD monitor’s screen is like a mirror, and it reflects the light from your computer’s display back at you. Black spots on display occur when small amounts of dirt and dust or smudges gather and are stuck to the surface.
Sometimes, dirt or debris may accumulate on your laptop screen, which leads to black spots that become visible to the naked eye and grow larger over time and can cause problems with screen resolution if left untreated.
These spots are typically easy to remove without damaging the monitor. However, failing to clean the dirt or debris on a regular basis, more of them will appear and gradually obscure more of your laptop’s screen, making the rest of the screen appear duller by comparison.
Though such black marks will not reduce the quality of the display of your LCD screen and cause any damage to the internal circuit of the monitor, they are very annoying.
The easy solution to get rid of these spots is to clean your screen with a moderately dampened microfiber cloth or soft eraser. Make sure you do not apply pressure while rubbing the display; instead, wipe it with gentle and circular strokes to avoid scratches and leftover marks.
Different types of pixel defects happen on LCD screens, including dead pixels and stuck pixels. Identifying the problem correctly will help you to choose the right methods to fix it that will not result in damaging the screen any further.
Most laptops have some pixel problems in them. The number of defective pixels you see depends on the screen resolution – the smaller the resolution, the larger they seem. In most cases, they are not noticeable during regular use as they are not bright spots, and if your laptop is free from pixel issues when you buy it, consider yourself lucky.
LCD manufacturing technology has improved dramatically over the years, and today’s panels almost don’t come with any such problem. However, as earlier as a few years back, there were times when defective pixels or vertical/horizontal lines would be let out into the market for lower-cost models.
When a pixel gets permanently damaged, it fails to receive power, resulting in a dark or black spot on your laptop display. This specific malfunction can occur during the manufacturing process of LCD monitors, and it is sort of permanent, which does not recover over time.
However, one can rarely experience such defects on their laptop screens out of the box since manufacturers strive to follow stringent quality control processes to make sure they deliver a flawless product. On the other hand, it’s quite normal to notice dead pixels appearing on the screen over time, depending on multiple usage factors.
Unlike dead pixels, stuck pixels are able to be powered on, which leads to a permanently colored pixel. They can be any of these three colors – red, blue, or green. While dead pixels are pretty much a permanent condition, a stuck pixel might just go away on its own.
Every modern laptop comes with a built-in LCD diagnostic mode that can successfully identify any pixel malfunction on your laptop’s screen. Follow the step-by-step method as below –
Now, turn the laptop on while pressing and holding the D key at the same time, and you will be taken to the self-test mode. Do not release the D key until the color bars appear on the LCD.
The monitor should display multiple color bars that constantly change from one color to another, which you want to inspect carefully in order to find out any distortion or irregular pixels.
On the contrary, stuck pixels are not dead and can receive power like other normal pixels; however, they get stuck on a single color always (hence, the name), which is either red, blue, or green.
In a dead pixel, all three of the colored sub-pixels – red, blue, and green – are forever “dead” or turned off and can’t be illuminated, so it looks like a black spot to our eyes.
However, it’s tricky to differentiate between dead and stuck pixels by naked eyes; therefore, you may want to look for other ways. If you are using a Windows laptop, install a free software named “InjuredPixels” – you can Google for its official website and download from there. Or if it’s a Mac, “LCD DeadPixel Test” is a browser-based tool (so nothing to download or install) that can help.
Spotting any defective pixel is relatively easy using these apps. They run single solid colors on your display so that you can quickly find out the malfunctioning pixel that doesn’t match the color of the rest of the screen real estate. You can further ensure whether it is a dead or stuck pixel before you attempt to fix it.
The common causes of an LCD monitor having a bad pixel are the following: extremely high or low temperature, a sudden drop in voltage, high levels of humidity, and static display over an extended period.
Keeping your laptop unprotected close to a heating source can force the pixels on the LCD to get solidified. Even lower temperatures below the allowed limit can lead to the same result.
Read the user manual for the ideal range of humidity levels within which you should operate your laptop. Keeping your LCD screen powered on in a high level of humidity may cause tiny droplets of moisture to enter the inside exposed areas of your display, resulting in a pixel malfunction.
Alternatively, you can let the laptop be turned off for about an hour and then turn it on. Repeat the process a few times and check for any changes in the pixels. This simple method is especially beneficial in case the stuck pixel shows when running a specific program and not other times.
In contrast, a black spot due to dead pixels is a more complex problem and hard to fix. You can find the few expert-recommended methods with comparatively higher success rates below.
If you find that your LCD panel display has dead pixels, there are a few things you can try. One of the simplest things to try is rubbing it gently, particularly if the dead pixel is on the edge of your screen where it is barely noticeable.
Before you try this technique, your LCD panel must be clean and free of dust and debris. Simply wiping with a soft cloth should remove most dirt and smudges. Also, using an object with a circular end, such as a smartphone stylus, and placing a soft microfiber cloth over the problem spot during the process will greatly reduce the risk of causing more harm to the screen.
JScreenFix is a website that can help you with your dead or stuck pixel issues. No expensive equipment or software is required as using the site is 100% free. All you need is just your laptop and an internet connection, and you are good to go. Below is a step-by-step guide that will walk you through the steps to solve the problem!
Once you have it on your laptop – open it up, move the red box to the area where you marked the dead pixel, set the timer, and click the “Start Flashing” button.
You would be in luck if your laptop was still under warranty period when you noticed the pixel defect. Take the unit to the official service center or the retailer you purchased it from and ask about the warranty claim process. In the majority of cases, any such pixel damages are considered manufacturing defects, and the company will simply replace the LCD.
No, both are different conditions. While dead pixels mean literally dead or not able to be activated or powered on and hence display no color, a stuck pixel does turn on and sticks to a single color instead of constantly shifting to red, green, and blue as required like a healthy and working pixel.
It depends. If you are experiencing a stuck pixel problem on your screen, it will likely recover by itself after a while in the majority of cases, without any user input. On the other hand, a dead pixel is more or less a permanent condition.
For stuck pixels, you have little to worry about as they usually disappear over time. However, dead pixels are mostly not user repairable. With that’s being said, JScreenFix and PixelHealer are two incredibly effective software solutions that you can use to restore your stuck and dead pixels – experts found their success rates pretty high.
Before you start looking for how to fix black spots on a laptop, it’s crucial to figure out exactly what caused the condition. Typically the issues people face are minor, and the black spots on their screens are a result of dust and dirt accumulation, which can be fixed with a simple cleaning.
However, sometimes it might be a symptom of a larger problem, including dead and stuck pixels that may require professional help. Unless you know what you are doing, we recommend you take your laptop to an authorized repair shop or claim a replacement from the brand if it’s still under the warranty period.
Imagine turning on your laptop to undertake a crucial task only to notice an unusual visitor: a black spot on its screen. This experience is scary at best, and it can be debilitating if you just broke the bank to procure the gadget.
Usually, when people notice black spots on their laptop screens, they conclude its screen damage immediately, just like you did when you first discovered yours.
However, not all black spots on your laptop mean screen damage. In this article, I will be taking you through some of the causes of black spots on your laptop screen and the possible solutions.Also, you’ll learn some maintenance tips to avoid future occurrences.
There are a couple of reasons you may have black spots on your laptop screen, but it’s usually because of a stuck or dead pixel.Dirt accumulating on the LCD surface may also cause black dots on your screen. Exposure to high temperatures and manufacturing defects are other causes of black dots.
Superficial dribs and specks of dirt at the surface of your laptop might be the reason why there are black spots on your screen. Specks of dirt gather on your LCD screens when you use them. When these specks of dirt are left unattended, they gather to form black spots on your screen.
This is a minor issue because specks of dirt don’t gather inside the screen but on the surface of the LCD screen. This makes it easy to correct by cleaning them off with a damp cloth.
Dead pixelscould also be why you have black spots on your screen. Pixels are the unit of color on your computer screen, and your LCD screen comprises millions of pixels that work together to produce images.
Pixels have to be illuminated by light before they can produce pictures. When the pixels are unable to illuminate light at all, they are said to be dead. This could cause a disturbing effect of a black spot appearing on your laptop screen.
Most people tend to confuse stuck pixels with dead pixels. While dead pixels won’t display any light at all, stuck pixels will get stuck on one color.
Pixels should change color to reflect the image on the screen. When this doesn’t happen, then the pixel is stuck. If the pixel got stuck in black, that could lead to a black spot appearing on your screen.
Exposure to high temperatures might be problematic for your laptop, and this is why there is a cooling system installed on most laptops. When used or exposed to high temperatures, the computer may experience lags and hardware issues.
The processors might also slow down in operation. Overheating may also trigger the appearance of black spots on your Liquid Crystal Display (LCD) screen.
Operating your laptop under unfavorable conditions is dangerous for the device. One of such is dry or moist air. Cleaning your monitor with a wet cloth can cause temperature problems, leading to condensation or conductivity.
So it’s essential to be wary of the environment in which you use your laptop to avoid defects like black spots. Try as much as possible to stay away from areas with low humidity.
Perhaps the most common cause of dark spots on a screen is physical damage. A drop or accidentally hitting your device against a wall or stronger body may lead to the appearance of irreversible black spots on the screen.
In rare cases, manufacturing defects might be why black spots appear on your screen. In this case, the only solution will be to replace the device with an alternative.
The specific way to fix the black spot on your laptop screen depends on the case. If it’s just dirt, wiping it with a damp cloth will do. However, stuck and dead pixels might be pretty stubborn, but almost everything has a fix.
When you notice stuck pixels on your laptop screen, you shouldn’t take immediate action. Wait and observe the stuck pixels to see if it goes away on its own. However, you may have to turn to the second option if it doesn’t.
Clean the affected part of the screen with a soft cloth; this should erase the stuck Pixel. You can also attempt rebooting your computer to see if that helps.
Gently use a soft microfibre cloth to light massage the affected pixels. This may correct the fault, and if it doesn’t, you may have to perform a full-screen replacement.
Another way you can fix black spots on your laptop screen is by using the pressure method to correct pixel faults. This is done using a soft cloth and a pen or pencil with a rounded end.
To fix your faulty screen using the ‘Pressure Method,’ you only need to fold the cloth, put it on your laptop screen, and apply pressure using a pen or a pencil with a rounded end. Do this till the faulty pixel returns to normal if it ever does.
The tapping method can also correct faulty pixels on your screen. To use this method, you’ll also need an item with a rounded end, like an eraser or a pen. However, this time you won’t need a soft cloth.
Using a wallpaper effect or a blanker, display an all-black background on your screen. Directly tap on the affected part of the screen with the eraser or pen. Apply enough pressure so you can see a white glow when you tap the screen.
Another way you could get rid of black spots on your laptop screen is to download pixel repairing software. These programs are specially designed to find and repair faulty pixels on your laptop, but there’s no guarantee that they’ll work for you.
Ink on a laptop screen is mainly caused by a fall or a hard impact. Your best option would be to replace the screen when you notice ink accumulation. Even if you choose to use it anyway, the ink will spread to the rest of the laptop screen sooner or later.
If you’re not financially buoyant enough to replace your laptop screen, here are some simple precautions you can take to stop the ink from spreading across your laptop screen.Immediately you notice an inky screen, try limiting the movement of your laptop as much as possible. The more you carry the device around, the more susceptible it is to damage. Get a padded traveling case for extra protection if you carry the laptop around.
Avoid cleaning the screen with ammonia cleaning agents. Ammonia weakens your laptop’s screen and accentuates cracks, helping the ink spread much faster.
You should also avoid poking or touching the screen with your fingers. This will only worsen the condition. If you must point at your computer, try to refrain from touching your screen.
Prevention is better than cure, says an adage. Nobody wants to get black spots on their laptop in the first place. If you haven’t got one already, here are some expert tips to prevent black spots on your laptop screen.
When cleaning your computer, use a soft and damp microfiber cloth. Avoid using rough fiber or cleaning agents containing acetone, ammonia, or alcohol. These are all strong liquids that could potentially damage your LCD screen.
When substances like ammonia get on your keyboard, it could cause the paint to fade away. Using ordinary water should be enough to wipe the dust off your laptop.
Lastly, frequent exposure to direct sunlight can also damage your laptop screen. If you are using your laptop to work in the open, try to limit the exposure of its LCD to direct sunlight to prevent stuck or dead pixels.
Exposing your laptop to high temperatures can be disastrous. Most laptops will malfunction when exposed to temperatures over 35 degrees centigrade, and this is because of overheating of the batteries and other internal and external hardware.
It’s essential to maintain normal temperatures when using your laptop for optimal performance. Getting regular temperatures will also help prevent black spots on your screen in the first place.
If the black dot results from stuck or dead pixels, you can fix it by using a damp cloth to wipe your laptop screen carefully. You can also use pixel repairing software out there on the internet.
Yes, software like Dead Pixel Buddy and Jscreen will help you detect and fix problems with your laptop’s LCD. They are straightforward to use, but the success rate when using one of those programs is meager.
To get rid of black spots on your laptop screen, use a soft microfiber cloth to clean the affected part. You can also use screen repair software to help you get rid of black dots on your laptop screen.
Dead pixels will not go away themselves, and you can get rid of them by following the tips in this article. These range from wiping the screen with a microfiber cloth to replacing the screen entirely if there seem to be no solutions.
While you can’t directly fix a dead pixel, you can revive them. You can do this by using a damp cloth to wipe over the area with the dead pixels. If you can’t do it yourself, you can always contact a technician for professional help.
Locate and mark the dead pixel with any removable writing material, preferably a sticky office note. Apply pressure gently on the pixel using one finger using a damp cloth. With your hand still massaging the pixel, turn your laptop on, and this should clear the dead pixel or prevent it from spreading.
Irrespective of the brand you use, the procedures for fixing black dots stay the same. The pixel correcting software for HP will work for other brands, and the manual pixel correcting process will work on all laptop brands.
As you can see, fixing a black spot on your laptop isn’t a complex process, and you may not even need it if you take proper care of your device. They can easily be corrected if you know the required steps, whether stuck or dead pixels.
However, if the defect is complex, do not hesitate to contact a qualified professional for help. If your device is still in assurance coverage, you should return the computer as soon as you notice a black screen.
I got this strange ‘dust problem’ on my Mac. In December 2009 my dream came true and I purchased new lovely Apple iMac 27”, 2.66, i5. One day I have noticed dark grey smudges on both sides of the screen (left and right). I actually didn"t notice any spots until I changed the background to pure white (or any other solid color really). At first, I thought it was fingerprint smudges or something. I cleaned the entire screen and it still remains.
I contacted with Apple service and they said iMac is very sensitive to dust. They call it ‘interlaminar dust’in matrix. As time passes, dust accumulates inside the machine and irreversibly penetrates the LCD itself, causing the dark stains. They blamed environment in my room! My Mac is placed on a normal work desk with lots of space around it and not more dust then in a normal house. Not that I am surprised that iMac is very sensitive to dust but I am so woefully disappointed.
Most people believe it was a factory defect on the LCDs. The only trouble they say is how to convince Apple Service to make a replacement of LCD under Apple repair program. They say if you pushy enough might get lucky and Apple might fix it for you.
Unfortunately the only way to determine if the problem is in the display or in the motherboard is to replace the display and check if the problem still occurs.

All Pixel phones have proximity sensors. Because the Pixel 5’s display goes almost to the edge, you can see the Pixel 5’s sensor under the screen. Check our Pixel 5 phone diagram.
IMPORTANT: A factory data reset will remove all data from your phone. While any data stored in your Google Account will be restored, all apps and their associated data will be uninstalled. Before you perform a factory data reset, we recommend backing up your phone.
Any TV with a liquid crystal coating, even the most expensive and proven as a reliable technology, may be malfunctioning or quickly deteriorate if used improperly. In this article, we will try to figure it out and find out what needs to be done if a dark spot appears on the LCD TV screen.
Such “blots” and dots are often first slightly visible and invisible, and then grow and interfere with viewing TV shows, distorting or closing the panel. In this section, we will try to understand the causes of the malfunction.
Often a dark spot formed on the liquid crystal coating indicates a malfunction of the most important part - the matrix. Basically, these are factory defects.
The defect appeared at the factory itself. If you purchased an LCD device and found a dark growing spot on it, immediately bring the device back to the store, provided that the warranty has not expired.
The appearance of a dark unpleasant spot on the plasma TV screen indicates a problem with the blocks themselves, the image being edited. Most likely, these blocks have already worn out. Also, in rare cases, the device manufacturers themselves are to blame.
Important! During operation, scratches can form on any item, and the TV screen is no exception. In our separate review, we described in detail howremove screen scratches.
Such “blots” often appear on such a model; the most common cause is the shedding of the phosphor deposited on the inside of the monitor. It also provides viewing of TV channels.
This defect occurs as a result of shock, pressure, falling of the picture tube or its wear. Here only the replacement of the tube itself can help, but it costs a lot of money. It happens that it is impossible to change it. Only buying a new TV will help.
Important! Remember that if the warranty for the equipment has not yet been issued and may still be valid for some time, then immediately contact a service center in your city and hand over the equipment according to the warranty sheet.
If the warranty is over, try to write a letter with claims to the manufacturers. In extremely rare cases, in order not to lose their reputation, factories can replace faulty equipment.
Important! For the future: for the warranty period and the manufacturer’s obligations to work for sure, buy the equipment of reputable companies. These are mainly brands such as SAMSUNG, LG, SONY, PHILIPS.
Important! Some owners of Smart TV have problems connecting the Internet to the TV. Our site of useful tips will help you solve this problem, read the special post “How to connect the Internet to Smart TV?”
It also happens that for no reason color stripes and “blots” appear on the monitor, which terribly distort the image. Such a story only happens with old picture tubes.
When you witness the appearance of such spots on the TV screen, do not rush to run to the store, take the equipment or write angry letters to the manufacturers, because such a problem is very simple to fix yourself.
So, we figured out the reasons, but what to do to make the strange glow disappear? It’s not necessary to call the master to the house, the whole problem can be eliminated independently:
The most popular and easiest way is to unplug the appliance for several hours and turn it on again. If the problem persists, try again. For prevention, this procedure can be carried out once a month.
If the method presented above did not work, most likely your posistor burned out. In this case, you need to replace the thermistor with a working one, but this is not an easy task. We recommend involving a master in this, so as not to break through your technique.
In the proposed article, we figured out the causes and methods of eliminating various spots on TV screens of any shape and size. Remember that even a well-proven technique requires special vigilance.
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.
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.
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.
Whether you’re a student, a businessman, or a content creator, you need your phone and laptop in perfect working condition to get some work done in today’s digital world. It can be very distressing and even frustrating to see black spots on your phone’s or laptop’s screen.
While your first instinct might be to get the screen changed, that’s not always the right solution. There can be other reasons for black spots apart from screen damage, and solving them doesn’t necessarily need to be so costly. So, if you see a speck on your screen, don’t worry. This tutorial talks about possible reasons for these black spots and how you can fix them.
Black spots are just surface blemishes that occur for several reasons, and they can occur at any part of the screen. They can either be just small dots or appear as a dark shadow in the corner of a screen. These dots don’t indicate broken glass, and they won’t cause the display to die out on you.
Although these black dots are easy to fix, it’s essential to understand what’s causing them so that you can take the proper steps without damaging the LCD. Apart from overheating and manufacturing defects, black dots on your screen can be because of the following reasons.
If left untreated, they can grow and eventually block more of the screen and make the rest of it seem dull. While these spots won’t damage the LCD, they are super annoying. Luckily, they’re quick to deal with.
Pixels change colors to display the image on your screen. But in some cases, a pixel can get stuck on one color. If that color is black, you will see a black spot on your screen.
Black spots on your laptop and phone screen can also be because of dead pixels. An LCD comprises millions of pixels that come together to render the image to your screen. But to produce pictures, pixels must be illuminated by light. And when they don’t illuminate at all, they are known as dead pixels. As a result, you see a frustrating black spot on the screen.
External pressure on the screen can also cause black spots. Pressure on the screen distorts colors and causes it to darken. The touchscreen used in phones today is so thick that touching it doesn’t apply too much pressure to it. But a swelling or bent part inside the phone can lead to internal pressure, resulting in a dark spot.
Black spots on your laptop and phone screen usually occur because of physical damage. If you accidentally drop or hit your device against something hard, you can expect to see irreversible black spots that will only spread with time.
Damaged LCD components can also result in dark spots. LCDs consist of tubes of liquid crystals. If these tubes break, the liquid starts to leak out, resulting in dark spots on the screen. You’ll be able to see them even with the screen turned off.
Black spots can appear for many reasons, and to fix them without causing further damage, you must determine the cause first. Different kinds of issues call for distinct methods, and there’s no one sure-fire way that can fix the spots. For instance, you can wipe the screen to get rid of dirt, but you can’t do the same to fix a dead pixel.
If the black spots are due to dirt and debris, you need to use a soft eraser or a slightly dampened microfiber cloth and clean the screen. Avoid putting pressure on the screen. Instead, use gentle strokes to avoid leftover marks and scratches.
Spray some cleaning solution on your laptop’s or phone’s screen. Then, use a stylus and apply a little pressure on the dead pixel to move it from its place. Once it starts to move, drag it off the screen.
You can put a soft microfiber cloth between the tip of the stylus and the screen while dragging off the dead pixel to reduce the chances of damaging the screen.
Another way to fix stuck or dead pixels on your laptop screen is with the help of JScreenFix. The website is 100% free and doesn’t require expensive software or equipment; you only need an internet connection and a laptop. Here’s what you need to do.
If JScreenFix doesn’t work for you, you can try using PixelHealer for your Windows laptop. This free application works pretty much in the same way and is a great way to get rid of stuck pixels.
DPTF is a free app with an easy and self-explanatory interface. It also uses the same process and takes 10 minutes to 1 hour to fix the dead pixels. When running the app, make sure your phone is fully charged and connected to a power source.
If all else fails, the best thing you can do is get the LCD replaced, especially if your device is still under warranty. In most cases, pixel damage is considered a manufacturing defect, and the manufacturer will replace the LCD.
You now know what’s behind the black spots you’re seeing on your screen and how you can fix them. While these spots seem scary and worrisome, it’s easy to take care of them.

While black spots may not appear immediately, they can cause distorted images or even the entire display matrix to become damaged. Some common causes of black spots on TV screens include dirty pixels, plugged in devices, and loose connections. Here are a few ways to fix them.
First, you can try resetting the TV to its factory settings. This process will remove any current settings and allow the TV to reboot internally. After performing the reset, you’ll need to reload any applications and enter any user accounts and passwords. Then, the problem may be solved. If the problem persists, contact Samsung technical support for help. They will send you a free replacement screen.
If you notice a black spot on your Samsung LED TV, there are several things you can do to get the problem fixed as quickly as possible. First, try removing any connected devices and disconnecting the TV from power. Then, wipe the screen to eliminate any debris or dirt that may have accumulated. If the problem persists, contact Samsung technical support for a free replacement screen. You may also need to adjust the signal strength on the screen of the television.
If you can’t fix the problem after removing these sources, try resetting the TV. Resetting the TV will remove all of its current settings and allow it to start over. Make sure that you use the best quality HDMI cables to connect external resources. Unplugging the source may also fix the problem temporarily.

If you have a Samsung television and notice some black spots on the screen, you’re not alone. This is an extremely common problem. Over time, dirt and dust can accumulate on the TV’s surface, leading to the formation of black spots. Luckily, there are a few easy fixes you can try to get rid of the black spots and restore the clarity of your TV’s picture. To begin, follow these simple steps:
Clean the screen: Use a soft cotton swab to clean any stubborn spots. Clean both sides of the screen, front and back. For the front, you can use more force to clean the screen than the back. But be gentle: the TV’s screen is sensitive and should not be subjected to extreme pressure. If the problem persists, contact a Samsung repair service. Otherwise, you may need to replace the screen.
Check your TV’s connection: If the screen is black, you should first check the cable connection. If you have an HDMI cable, the issue could be with the cable. If the TV is mounted properly, it will be stable and not shift, which could result in a shadow. If that does not solve the problem, you may need to replace the LCD panel. To do this, check the settings in the TV’s menu.
If your Samsung TV has a black spot on the LCD screen, it may be caused by dead pixels. Dead pixels are the result of an assembly problem, but they won’t affect the performance of your television or damage the internal circuitry of the screen. To remove black spots on the LCD screen, start by gently wiping it clean using a damp microfiber cloth. It won’t be too difficult, but if you don’t want to use a microfiber cloth, just wipe the screen with a dry one.
If you’re still having problems, you might want to try resetting your TV. Switching the input to another device may be what’s causing the problem. If you cannot figure out the exact problem, you can contact Samsung technical support to receive a replacement screen for free. You can also try cleaning the screen with an alcohol wipe. If none of these methods work, contact a technician to repair the screen.

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. Fortunately, many black spots are caused by defects in the television’s assembly process, and they can be resolved by the manufacturer. If this is the case, you should try a new TV instead.
If the black spot persists after these steps, you may have to replace the screen. You can try removing the power cord and try again. If you’re still having trouble, you may need to replace the screen or factory reset the TV. If the issue persists, you should contact the manufacturer for more help. In most cases, it’s not necessary to buy a new TV. You can remove the black spot on Samsung TV by following these steps.
With modern phones, that isn’t a problem because the touchscreen is thick and stiff enough that touching it doesn’t apply much pressure to the LCD part of the screen.
Technically, individual pixels can be replaced, but they are so tiny on modern screens that it’s not worth the time and money to replace single pixels.
