marks on lcd screen brands
Are you looking for how to get rid of those irritating spots on your phone screen? This article shows you everything you need to know on how to fix pressure spots on LCD screens and how to prevent them in the future.
One of the deadliest and most frustrating issues you could have with your mobile phone is screen damages. And for pressure spots on LCD screens, it"s somewhat annoying than breaking the whole screen itself, as it requires going for replacement in most cases.
As its name implies, pressure spots on phone screens can render the display useless (or irritating, based on how you see it) by creating spots of different shapes and styles on the screen. These spots show continually, and most times, permanently on the display and can obstruct your viewing or cause other problems such as dead pixels, flickering, or blurriness.
When you apply too much pressure on your phone’s display – whether accidentally, intentionally, or carelessly, it damaged the LCD components, hence creating different spots on the display.
Pressure spots on LCD screens can come in different forms and shapes depending on the density of pressure applied. Sometimes, the spots can be whitish, deep black, or come in various colors depending on what’s currently showing on the screen.
Unfortunately, learning how to fix pressure spots on LCD screens isn"t the same as learning how to fix simple hardware and software issues. Simply put, there is no way to repair a phone screen that was damaged by pressure.
Attempting to get rid of pressure spots on LCD screens can cause more harm than good. Hence, you had better find a professional phone repairer to help you with screen replacement.
Meanwhile, some users reported that the pressure spots on their phone screen got healed after a few years. But do you want to keep seeing the same issue on your screen for years? So, a screen replacement is the only way out.

Paying for screen replacement from your own pocket (especially when you don’t have any form of screen insurance or protection plan), can be a pain in the ass. However, there’s probably nothing you could have done better than learning how to protect your phone screen from pressure spots in the future.
Pressure spots on LCD screens (or any screen in general) occur accidentally or carelessly. The only way to avoid such damage in the future is to handle your phone carefully. Try as much to shun applying much pressure on the screen while playing games and performing other tasks.
When inserting your phone into your pocket, purse or bag, ensure there"s enough space to accommodate it. Also, ensure there are no other objects inside the pocket, purse, or bag.
Equally important, if you"re wearing a dress with tight pockets, we recommend you keep your phone somewhere else rather than forcing it inside the pocket, as it may be pressurized when you move your body.
Overall, the only way to prevent your phone screen from getting pressure spots in the feature is to handle it carefully whenever and wherever possible. If you ever come across the need to drop your phone somewhere, ensure you don’t place anything on it.
Taking these few things into consideration would help you protect your phone screen from pressure spots in the future, rather than looking for how to fix pressure spots on LCD screen when it happens.
Now, if you’ve accidentally applied much pressure on your phone’s screen and some spots are showing on it when you turn it on, the best thing you can do is to visit the official service provider for your device for a screen replacement. Trying to shift the spots away or performing some DIY tricks may cause more harm than good.
The most annoying thing about laptop damage is having a problem with its screen. It is not enough to have the laptop in good working condition. Rather, it is best if the laptop looks perfect on the outside too.
Some laptop problems do not need an expert to fix, you can do it as a DIY project. Find out how to remove pressure marks on LCD screens as explained in this article.
Pressure marks, despite how nasty they can be, unfortunately, have no specific fixing techniques. You might be lucky if you manage to remove the damage without interfering with your laptop’s part.
Liquid crystal displayis a technology used in making many electronics’ screens. Mostly found on monitors, TV screens, and even phone screens, the technology creates images by illuminating light through multiple liquid crystals.
Pressure application is the major cause of damage to these screens. This is because these screens are very sensitive. The liquid crystal, in the LCD screen, is fixed between two glass sheets.
After purchasing a good LCD screen, usually, you feel so contented; not knowing with time some problems may arise. The most common issues experienced are:
When you turn on the monitor, you may realize sudden flashes are appearing. On most occasions, the major reason for this to happen is having a loose video cable.
Tightening the cable will resolve this problem perfectly. Make sure you’re not using a cable that is faulty. Suppose the cable is damaged, buy a new one to replace it.
The mark does not damage your screen, although it can be frustrating seeing it there. There is software to solve this. They work by forcing the area with the dead pixel to experience a rapid change of colors.
This is a layer of a crushed crystal, found between two glasses that makes the screen. They form due to physical pressure exerted on the screen. The pressure forces the crystal to lose its solid properties.
Therefore, it makes the computer not manipulate the crystals to filter the backlight. This at times even pushes the crystals out of their fixed position. They either tend to rotate or get twisted.
To prevent it, you will require less pressing of the screen. Avoid unnecessary holding of the screen, not unless it’s a touch screen that is designed to withstand pressure.
This should also apply when you are wiping the screen or other sensitive laptop parts like the touchpad. Ensure you do it lightly and gently. While traveling, ensure your laptop is closed properly without having any object that will exert pressure between the keyboard and screen.
Pressure marks are a result of physical force that occurs when a laptop is mishandled, example when you bring the laptop to a plane. Therefore it will require physical fixing attention.
Physically fixing the screen also is not a 100 percent guarantee of solving the problem. It may even result in worse damages since it will require opening the laptop parts.
If the spot does not obstruct you from working well, then you can ignore it. It will help you save on the cost of getting a new laptop after an unsuccessful attempt to repair the problem.
Having black spots on a TV screen can be very confusing and annoying for most TV owners. If you just spotted a black spot on your TV screen, you are probably worried that you’ll need to replace the entire set. But this should not be the case, especially since you spent a handsome figure getting the best TV available.
Perhaps the most common cause of black spots is dirt and debris that have accumulated on the surface of the TV screen over time. If ignored, it will lead to black spots.
Most TV owners would consider sending their TVs back to their manufacturer when they spot a black spot, like sending your best Vizio TV back to Vizio. 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.
Black spots can be a pain, especially if you just bought a wide color gamut TV and are looking to have enjoyable weekends. Regardless of where the black spot is located on your TV screen, it will stand out like a sore thumb. It’ll be the first thing you spot when your TV screen lights up. Black spots on your TV screen are caused by debris, dead pixels, or stuck pixels. This can be especially annoying if you invested in the best anti-glare TV and depend on good visuals for a good TV experience.Dirt or Debris: Perhaps the most common cause of black spots. Dirt and debris accumulate on the surface of the TV screen over time, and if ignored, will lead to black spots. 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. Black spots caused by manufacturer defects are usually covered by a warranty.
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 that is common among new TVs but often disappears as time goes by.
Regardless of where the black spot is located on your TV screen, it will stand out like a sore thumb. It’ll be the first thing you spot when your TV screen lights up.
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.

A pressure mark is a sign of physical damage to the inside of an LCD screen. It is related to, but not always synonymous with, the problem of dead or stuck pixels. Usually it is not financially viable to repair pressure marks.
Virtually all laptops have a liquid crystal display screen, mainly because the technology lends itself to light and thin screens. LCD involves shining light through a sheet of crystals which combine properties of a solid and a liquid. These crystals are red, green and blue and can be electrically controlled to be "on" (meaning they let light through) and "off" (meaning they block light.) The combination of the different colored crystals across the screen being either on or off and the backlight passing through creates the colored image on the screen.
A pressure mark is where physical pressure on the screen has led to the layer of crystal being crushed between the two layers of glass that surround it in the screen. This could cause crystals to lose either their liquid or solid properties, meaning they can no longer be manipulated by the computer to act as a filter for the back lighting. Another problem is that the crystal may be pushed out of position, for example by being twisted or rotated. These forms of damage may be visible in the screen by showing the wrong colors, or the image may be blurred or distorted, looking a little like if a drop of water fell on a painting that hadn"t yet dried.
A stuck or defective pixel is a specific problem with a laptop screen. It may be a symptom of the damage that caused a pressure mark, but may also be the result of unrelated problems such as electrical failure. A stuck pixel is one in which at least one of its three sub-pixels (which are colored red, green and blue) remains permanently on or off, meaning the pixel will often appear to be the wrong color. A dead pixel has all three sub-pixels permanently off, meaning the pixel is continually black. The fact that pixels are extremely small means that most pressure marks will involve numerous pixels being affected, whereas other causes can lead to a single pixel being dead or stuck.
To reduce the risk of pressure marks, avoid pressing or holding the screen wherever possible (unless of course it is a touchscreen, which is designed for such pressure.) Take particular care not to press down when wiping the screen. When transporting the laptop, make sure it is securely closed and that you have not left any objects such as a pen or a magazine between the keyboard and screen.
Some online resources claim the ability to fix dead or stuck pixels through techniques such as repeatedly flashing the screen dark and light. While the success of these techniques is debatable, they are not relevant to pressure damage as they are attempting to fix an electrical fault. Pressure marks are a sign of physical damage which cannot be undone without physical attention to the layer of crystals -- and even this is not a guaranteed fix. As physically dealing with the crystals involves taking apart the laptop screen -- a tricky and intricate task -- it is rarely if ever economical to fix a pressure mark compared to replacing the screen (if that is possible with a particular laptop) or replacing the entire laptop. If you do get a pressure mark on your screen, generally you will have to decide if the visual annoyance outweighs the cost of replacing the screen or laptop.
A professional writer since 1998 with a Bachelor of Arts in journalism, John Lister ran the press department for the Plain English Campaign until 2005. He then worked as a freelance writer with credits including national newspapers, magazines and online work. He specializes in technology and communications.
Screens can scratch easily, and even paper towels and tissues contain fibers that can do damage. “Your best bet is to use a soft, anti-static microfiber cloth—the kind used to clean eyeglasses and camera lenses—and wipe in a circular motion,” says John Walsh, who cleans more than 250 TVs a year in his role as a CR photographer. (Some TV manufacturers will include a cloth for this purpose.) “Gently wipe the screen with a dry cloth to remove dust and other debris, but don’t press too hard,” he says.
You may also want to wipe down the TV’s cabinet, and make sure dust isn’t clogging the vents that help dissipate heat. If the TV is on a stand and not tethered to the wall, Walsh suggests cleaning with one hand while supporting the TV with the other to prevent the set from tipping over. However, CR strongly recommends anchoring all stand-mounted TVs using anti-tipping straps designed for this purpose.
If there are hard-to-remove stains, you can dampen the cloth slightly with distilled water and gently clean the screen. Don’t spray water directly onto the screen; that could cause a shock or component failure if water seeps into the inner workings of the set.
For the most stubborn stains, you can try using a solution of very mild dish soap highly diluted with water, once again applied to the cloth and not to the TV itself. (As a guideline, Panasonic used to recommend a 100:1 ratio of water to soap.) LCD screens, in particular, are very sensitive to pressure and can scratch easily, so don’t press hard.
SecretCeremony from what I"ve read it looks like voltage issues on the LED driver board that control the LED"s. I would start with a new main board (yes I"d buy it from somewhere where I can return it in case it does not work) then re-evaluate on that.
The LCD panel will be connect to a driver board that is part of the panel, take a look on that one and see what you find. Post some good images of that board with your question so we may be lucky and find some sort of schematic etc. I would even contemplate on getting a universal driver for the panel just to see if the same issues are present when every board from the TV is disconnected. Sounds like a lot of work and maybe even some $$$ foolishly spend but I do not like to concede defeat.

Remember when your computer LCD display had that brand-new, fresh out-of-the-box shine? If it"s looking a little dull lately, it might be time to give it a good cleaning. Here"s how:
Step 2:Gently wipe the dust from the surface of the display using a dry, lint-free cloth, like a microfiber cloth. Remove any tags that may be on the cloth to avoid scratching the display with the tags.
If you prefer, you can use a cleanser made specifically for cleaning LCD displays, but do not spray it directly onto the display. Spray a small amount of the cleaner onto a microfiber cloth first, to avoid getting any cleaning solution inside the display.
Even if you don"t have snot-nosed kids or wet-nosed pets, your computer monitor or HDTV panel will eventually accumulate a collection of annoying smudges and stains. My household happens to contain both of the aforementioned creatures and, thus, I"ve developed a method for wiping down the HDTV in the living room and the LCD monitor in my office, as well as the screen of my laptop and iPad.
If you take a quick survey of LCD or HDTV manufacturers about the recommended method for cleaning the surface of your monitor or TV screen, you"ll discover more don"ts than dos, often in conflict with one another.
In the don"t column:Don"t use aerosol sprays, solvents, or abrasives. (This means don"t reach for the Windex under the kitchen sink, as tempting as it may be.)
First, attempt to clean your screen with a dry, lint-free cloth. If you can"t find the cleaning cloth that came with your screen in question, then it"s likely you have one laying around from a laptop, iPad, or iPhone purchase.
After removing any dust from your screen with a dry cloth, dip the other cloth in your dish soap solution, wring it out, and gently wipe your display. Next, rinse out your soapy cloth, wring it out again, and wipe your display to remove any soap residue. Finally, take your dry cloth and wipe the display to remove any streaking.
However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.
If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.
Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.
A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.
Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.
A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.
Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!
Keeping your precious rugged LCD monitors or LED screens clean and tidy can be challenging. This is especially true if you happen to have handsy young children who like to touch everything or pets running amuck in your household or even if you happen to work in a particularly messy environment such as a construction site or restaurant. Sometimes, rogue bits of debris can attach themselves to your electronic devices and while this is entirely out of your control for the most part, there are a few effective and harmless cleaning solutions you can put into practice to keep your electronics clean and running smoothly. Continue reading to learn about helpful tips for cleaning your LCD and LED screens without causing internal or external damage.
Before you can get down to the cleaning part, you need to prepare your LCD or LED screen in order to reduce the risk of liquids penetrating the surface and causing internal damage. Keep in mind that modern screens might technically include higher end features than the old school CRT screens from your childhood, but that doesn’t necessarily mean they’re more durable. In fact, modern LCD and LED screens are actually a lot more fragile and easily susceptible to damage if they’re not cared for properly. To prepare the screen for cleaning, make sure you shut down the system entirely, disconnect it from its power source, and then let it cool down for a few minutes. This will reduce the risk of electrocution and it’ll make it easier to clean the screen without resulting in annoying and unattractive streaks.
Occasionally, you’ll have to contend with a tough spot, streak, or fingerprint marking that takes a little extra effort to clean. If this happens, don’t panic and definitely don’t press down harder with a cloth or try to scrape it off with your fingernails or any other tool as this can cause severe damage to the top layer or anti-gloss coating. The best thing to do is use a non-abrasive cleaning solution such as isopropyl alcohol that’s diluted with either pure or distilled water. Spray the solution onto a microfiber cloth and gently wipe down the area in either an up and down or side to side motion. Applying too much pressure to even the most rugged touchscreen can compromise its limited durability.
There are a few types of cleaning cloths you can use to wipe down your rugged LCD monitor either at home or at work. The most recommended one is microfiber cloth for a multitude of reasons. First, microfiber is a state-of-the-art technological development that’s a thin and soft, yet strong enough material to thoroughly clean your electronic devices without risking damaging them in any way. Most of the time, computer and flatscreen TV manufacturers provide microfiber cloths with their products along with a specific set of maintenance and cleaning instructions. Microfiber cloths are immune to collecting or spreading lint across your screen, and because of the intricate way in which the minuscule fibers are intertwined these cloths are able to trap larger quantities of dirt and dust without leaving streaks. You can also use a cotton tea towel, a cotton t-shirt, or cotton handkerchief if you’re in a bind and don’t have microfiber cloths on hand.
This point can’t be emphasized enough. Even though it may seem like common sense that electronic devices shouldn’t come into direct contact with any liquids (especially if they’re still plugged in), not everyone seems to think so and many people have made the mistake of spraying cleaning agents onto their devices. The safer and smarter way to clean any rackmount LCD display is by first wiping it down with a dry cloth and then spraying a small amount of the cleaning solution onto a different cloth and wiping it down gently. After you do this, wipe it down with a clean dry cloth to remove any remaining liquid.
Always avoid using ammonia or rubbing alcohol based cleaners on your touchscreen devices. The devices themselves might be constructed with the capability to withstand most types of damages, but certain features they possess aren’t. Ammonia and rubbing alcohol can irreparably strip away or damage the extremely delicate anti-glare coating on the screen, which will not only negatively alter your viewing experience but also make your device a lot harder to use in strong sunlight.
Dust that settles between the gaps in the screen where the bezel and the top layer of glass or plastic meet can penetrate deeper and cause internal damage to your device. Regularly using a vacuum with a soft-bristled brush (to prevent scratching) can help you keep your device clean and free of any issues.
For extra measure, you can also spray the surface of your screen, computer keyboard, or even the vent on the back of the device with a can of compressed air to blast away any lingering and stubborn debris or dust. If any of it lands on the surface of the device, make sure to gently wipe it away with a clean cloth to prevent it from making its way back into your device. Implementing this cleaning method on a regular basis will ultimately help to guarantee the longevity and functionality of your device.
