Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.
No, accidental damage is covered for Dell computers or monitors which are covered under the Accidental Damage Service offering for that specific product.
For more information about Dell Limited Hardware Warranty and Dell"s Accidental Damage service offering, see the Dell Warranty & Support Services page.
NOTE: Other damages may be considered customer induced if determined by Dell Technical Support, an on-site field engineer, or at the mail-in repair center.
The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.
Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, attempting to close the lid while an object is on the keypad area, or even holding the laptop by its screen.
Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.
If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.
Dell monitors cannot be repaired by an on-site field engineer or at the mail-in repair center. If you notice any damage to the monitor, you must purchase a new monitor.
Laptop users can strive to make the most of their laptops to maximize stability, longevity, and usability. Understanding and implementing a few best practices for the safe handling of their laptop will enable them to enjoy their laptop for many years to come.

LCD display screens on tablets are made of two thin layers of glass with dark liquid crystal material in between. The glass is covered on the outside by a layer of plastic. Customers often feel there cannot be a broken LCD display because they cannot feel the break. However, cracks in the glass usually cannot be felt because the plastic covering rarely breaks or fractures.
Black “spots” might also appear. This can be liquid crystal material spilling out of a crack. A crack might be present which causes lines to appear but no liquid crystal spots are apparent. The spots might be small or might appear later or grow larger in time. Customers often say that there were no black spot(s) when the unit was sent for repair, so it must have occurred during or after shipment.
It is important to understand that lines on the LCD can also be caused by video driver issues or a problem with the media you are using. Video driver issues can normally be resolved by downloading and installing a new video driver. However, if the damage is due to a broken LCD, you should understand the following policies.
Once you have found the correct part number, see HP Consumer Notebook PCs - Ordering HP certified replacement parts. Use the instructions in this document to order a replacement part.
HP recommends that you only order parts from an authorized HP repair parts dealer. Parts ordered from third-party companies might not perform as expected and might cause additional
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!
Ok.... look. I am working on a PhD in Robotics and hold an MS in electrical engineering. These spots will go away, but only after many on/off + rgb + bl cycles UNLESS the screen is cracked. Electrons displace themselves from each other. At some point, something got squished. My advice, use your device SPARINGLY but DO USE IT. Turn on the display at least once a day, no more than a dozen, for a few weeks. If the spots are growing, you may have a seal problem preventing the screen aligning itself. If they are EXACTLY the same. New screen bezel, sorry.

Knowing how to fix dead pixels is a good skill to know. If you’ve noticed unusual spots on your display, you might be dealing with stuck or dead pixels. Fortunately, these pixels are usually harmless and can be detected using special pixel tests.
Dead and stuck pixels can appear on LCD screens of all kinds. This includes monitors, phones, and camera displays. It’s easier to spot them on larger displays, though.
If you’re using a camera, carefully look at your LCD display as you take photos. Are there any spots that stay in the same place no matter how much you move your camera? Those spots are dead or stuck pixels.
There’s a distinct difference between stuck and dead pixels. If you’re completely sure that the pixels on your screen aren’t dust, you need to identify them.
Stuck pixels are usually red, green, blue, or yellow. Dead pixels are black. No matter how much your screen changes, those pixels will remain fixed in one spot and won’t change their color.
Keep in mind that stuck pixels can also be black or very dark in color. You might accidentally mistake them for dead pixels. To make sure that they’re not dead, you need to use a dead pixel test. More on this later.
Stuck pixels are much easier to remove than dead pixels. If you’re sure that there’s a dead pixel on your screen, you’ll probably have to hire a specialist or replace your display.
Here are a few simple websites that let you check for dead pixels using solid colors. They basically do the same thing, but one of them might be more compatible with your device/browser than the other.
You need to be in full-screen mode. Make sure you wipe your screen beforehand so that you don’t accidentally mistake a speck of dust for a dead pixel!
Click on each color. If you don’t notice any unusual spots (black or any other color) on your screen, it’s likely that you don’t have an issue with dead or stuck pixels.
Some users recommend rubbing a dead pixel using a cloth to get rid of it. This might work temporarily, but it will damage your display in the long run.
Too much rubbing can damage even more pixels on your screen and lead to serious problems. If none of the solutions work, the best way out is to contact a specialist.
As mentioned previously, dead pixels are usually impossible to remove without professional help. However, you need to make sure that those dead pixels aren’t secretly stuck pixels or simply dust particles.
This is a very simple and seemingly straightforward method. But it might be the best solution to your problem. If your screen appears glitchy, it might simply need to be refreshed.
Use a screen-cleaning spray and a cloth to wipe your display. Make sure you don’t apply too much pressure or else you might damage your screen. A few gentle swipes might get rid of the problem.
If the options above don’t work, JScreenFix might be your best solution. This is a website that anyone can use for free. You don’t need to download any programs or extensions to use it. Best of all, it promises to remove stuck pixels in less than 10 minutes.
What JScreenFix does is fix stuck pixels. If you think you have a dead pixel, you can try this method as well. For this to work effectively, you need to know where exactly your stuck pixels are located.
Your job is to find the stuck pixel and drag the box to it. Leave it there for a few minutes. This should get rid of any unusual pixels on your display.
If you’re sure that the pixel is dead (and not stuck), then you’ll need to see a specialist. There are a few methods for fixing dead pixels, but most of them don’t seem to work effectively.
Dead pixels usually don’t spread. They’re usually a small fault in a display. If they do spread, you might need to hire a specialist or replace your screen.
Make sure you clean your display, take a dead pixel test, and use JScreenFix to get rid of the pixels. It’s likely that this will fix the problem and prevent you from consulting a specialist.
Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.
Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.
In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.
If you are concerned about pixel anomalies on your display, take your Apple product in for closer examination at an Apple Store, Apple Authorized Service Provider, or an Independent Repair Provider. There may be a charge for the evaluation. Genuine Apple parts are also available for out-of-warranty repairs through Self Service Repair.*
The most attractive part of your phone is the screen, yet it’s also the most delicate component. This is why it requires special care and attention. Physical damage to your screen mostly takes the form of obvious cracks in the glass, but you may also come across what appears like an ink spot (blot) or bleeding pixels. When the black spot is spreading on your phone screen, you need to have the screen replaced. If you try to repair the phone yourself, you may cause more damage to it, thus complicating the issue.
Trained technicians have a great wealth of experience in fixing various issues with a phone’s screen, offering you a flawless screen replacement service best suited to your specific model.
How to get rid of black spot on phone screen;When that happens, black and/or blue and purple spots may appear on your screen. If an individual pixel gets damaged, it’ll stay turned off and also appear black.
When more pixels become damaged, the black spots will spread over your phone’s screen like an oil stain. While there are some tips given online on fixing this issue, applying them may do further damage to your device. The best line of action to follow is to seek professional help.
Speaking of LCD screens, they can struggle with external pressure. If you’ve ever pressed on an LCD screen, you probably saw the colors distort and darken under your fingers.
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.
That boils down to a few causes. If dead pixels are expanding across the screen, it means that something is continuing to damage more and more pixels over time.
There are a few possible explanations for black spots on your smartphone screen or iPhone screen. So black spots on a phone screen can be fixed. However, the fix may not be permanent and the spots may reappear over time. The cause of the black spots is typically a scratch or chip in the screen that exposes the underlying LCD panel. If the phone is still under warranty, the manufacturer may be able to repair or replace the screen. If the phone is not under warranty, a third-party repair service may be able to fix the screen for a fee.
The best line of action to follow is to seek professional help. To solve the issue of black spots spreading on your phone’s screen, you need to get the screen replaced.
Stuck pixels aren’t like a disease or virus, they don’t spread around the screen. It is possible to get more, and if you have one the likelihood of more coming increases, but the dead pixel itself isn’t contagious so to speak. There are some temporary fixes that may work, such as flashing colors or rubbing the pixel.
Dead pixels are usually the result of a manufacturing defect. If a defect prevents a pixel from receiving power, the pixel will remain black at all times. Bumping into or knocking over a display device, for example, may damage the power connection to one or more of its pixels, in which case a dead pixel can occur. Take your device to an authorized service center or the Apple Store FOR A FIX.
Backlight bleeding is an effect where light leaks around the edges of your tv screen or phone screen, making it unevenly lit. This cannot be remedied, but it can be partially prevented by buying a high-quality monitor and being careful with it.
Have you ever left your TV or monitor on for days, stuck on the same image? You return to your screen, only to find an image burned into the display. No matter what you do, it won"t go away. It is a permanent image burn.
Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?
In some cases, you can minimize the image burn effect. In others, you can remove the image burn completely, so long as it hasn"t been burning too long.
Before flat-screens and crystal displays, most TVs and monitors featured CRT (Cathode Ray Tube) technology. In CRTs, individual pixels comprise a red, blue, and green phosphor component. Depending on the intensity of each phosphor component, the pixel appears to the human eye as a unique color.
When a particular still image remains for too long, the intensity of each phosphor component diminishes at an uneven rate. The result is a ghost image on the screen, which is known as image burning.
Plasma displays use plasma, a gaseous substance containing free-flowing ions. When the plasma is not in use, the particles in the plasma are uncharged and display nothing. With the introduction of an electric current, the ions become charged and begin colliding, releasing photons of light.
This is a very simplified version of how a plasma screen works. However, the main thing to understand is that plasma screens use phosphor material (like CRTs) to turn those photons into images.
LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.
LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.
Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?
First, let"s tackle plasma screen burn-in. Remember why CRTs experience image burn? When a still image remains on the screen for too long, the phosphor components in each pixel wear out at different rates. The uneven burn rates leave behind a ghost image, forever etched into the screen.
Plasma screens also suffer from phosphor deterioration. Plasma burning occurs when pixels on the screen are damaged through long exposure. The phosphor loses its intensity and only shows the light it was fed repeatedly. In this case, the still image, which causes the burn.
LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).
Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.
Image retention is a different issue from image burn (although it is a precursor to image burn). For example, you"re using an image of a steam train as a reference point for a drawing. You have the steam train image on your screen for a few hours before you decide to play a video game instead.
When you load up the video game on the screen, you can still see the faint outline of the steam train on the screen. The steam train image will remain for a short while, but the movement and color changes of the video game (or film, TV show, or other media type) should erase the retained image.
The other thing to consider is that LED and OLED image burn-in, when it happens, is irreversible. That"s because of how LED and OLED screens work. Individual pixels within an LED display decay when they emit light.
Under normal use, an LED, OLED, or QLED screen won"t suffer image burn. However, if you leave your screen on a single channel for hours every day, then burn-in can become an issue, as it would with almost any screen.
Issues arise when a screen shows a single news channel 24 hours a day, every day, causing channel logos to burn-in, along with the outline of the scrolling news ticker and so on. News channels are a well-known source of television burn-in, no matter the screen type.
Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.
The best fix for screen burn is to prevent it in the first place. Okay, that isn"t super useful if your screen is already experiencing image burn. However, you should always try not to leave your screen on a still image for too long. The time it takes for an image to burn-in varies from screen to screen, between manufacturers, sizes, and panel type.
My personal rule of thumb is to turn off the display if I plan on being away for more than 15 minutes. That way, it is difficult to get caught out, plus you save yourself money on electricity costs and monitor or TV wear and tear.
Another prevention method is to reduce screen contrast as much as you can. Unfortunately, most screens aren"t calibrated correctly, often pushing the contrast and brightness settings too high.
Lower contrast means the lighting across your screen is more even. This means less strain on specific areas of the screen, which helps protect against image burning.
If your plasma or LCD screen already has image burn-in, you can try turning on white static for 12 to 24 hours. The constant moving of white-and-black across your screen in random patterns can help remove the ghost image from your screen.
Unfortunately, this won"t work for extreme cases. Some TVs will have a built-in pattern swiping option that basically accomplishes the same thing (filling your screen with random patterns).
Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.
Other modern screens feature built-in screen refresh functions that the manufacturer will advise using to remove image retention and image burn issues.
The best tool for fixing ghost images is JScreenFix. The original program helps fix monitors with dead pixels, but the same company also released an "advanced" version of the tool, known as JScreenFix Deluxe.
While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.
You can find the free version of the Deluxe app online, but it is limited to 20 minutes running at a time. Furthermore, we"re not going to link out to the versions you can find online as we cannot verify the security of these installations. If you do use the Deluxe version, you do so at your own risk.
Another option is to set a completely white desktop background and leaving to run for a few hours. The solid color might reset the image burn. A solid color background is more likely to help with image persistence than image burn, but it is still worth trying.
If you have television burn-in, you can attach a laptop to your TV using an HDMI cable, extend your desktop to the television, and share the white screensaver. Hopefully, that will shift your television burn-in.
The team over at ScreenBurnFixer offers a few different ways you can attempt to fix screen burn on your TV or monitor. As with any other screen burn-in fixes, their chance of working depends on the scale of the issue.
You can head to the ScreenBurnFixer Video page and find a video that matches your screen type, then let the video play for as long as possible (we"re talking multiple hours, not a quick half an hour blast). Alternatively, head to the Chart page and find your device or a device that matches your specifications.
There are several ways you can attempt to fix screen burn-in. The results will vary between the screen type and the level of burn-in. A screen with extensive image burn may not clear entirely, although you might see an improvement.
Some screen degradation over time is understandable. However, if you follow the steps in this guide, you"ll protect your screen from image burn before it becomes a permanent issue.
You use your phone for at least a few hours daily, so seeing a black spot there is unpleasant. You can’t comfortably watch movies or write messages because you see that annoying black spot in the corner of the phone. The good news is that you can fix it! Read our troubleshooting guide on how to remove black spots from the phone screen and follow the expert advice we share.
There are two groups of reasons why the phone screen is turning black: software and hardware. If it’s a software problem, you can quickly fix it. You don’t need to go to the service center.
It is the most common reason for black spots on LCD phone screens. The only way you can fix it — change the screen to brand new. Every LCD screen had thousands of pixels. Each one has three tiny bulbs: green, red, and blue. And when some light bulbs refuse to work as intended, you get a “dead” pixel that looks like a black spot on your phone. There are two main sub-reasons for this screen issue:Pixels burned out. Most LED screens work for 5-7 years. After this period, pixels start to burn out. It’s a natural process.
This issue doesn’t spread out. It’s just a burnout bulb. If the black spot is getting bigger, it’s not a “dead pixel” case. That means you need to take more severe measures to prevent a display failure.
Pixels also can get stuck. It’s a software issue that leads to a black spot on the phone screen. Your phone gives instructions to the screen to turn on these tiny bulbs in the proper order. Sometimes software messes up, and pixels get the wrong color.
Here is an example: your display needs to turn some pixels white. To do this properly, it should turn on all three bulbs. But for some software reason, it turns on only two bulbs: red and blue. And this pixel turns out violet, but not white as it is supposed to be.
Sometimes the phone “forgets” how to turn on all three bulbs in the pixel. That’s why it can be black. Stuck pixels look like tiny dots that keep their size without growing.
Modern phones have a thick screen, so you don’t need to worry about pressure in ordinary situations. You can use your hands and stylus freely. But beware of other objects. If they are big or heavy, they could damage the display. So don’t lay massive things on your phone.
The phone can get a few new dark spots if someone sits or steps on it because such actions create excessive pressure in some screen areas. That’s why you can have a black spot on your iPhone screen. Android devices tend to have the same issues. Moreover, your phone can break due to excessive pressure if you own an ultra-budget (below $200) Android device. You should realize this threat.
Sometimes phones have internal pressure: from swollen batteries or other broken parts. It also could lead to black pixels. Find the source of the problem to fix it. If you don’t have the skills for this, go to the nearest service center. But be ready to pay $50-100 to repair your device.
LCDs have a slightly different construction. They are made from tubes that hold the crystals. That is why your LCD is never totally black. It has a mild illumination that you can see in a dark room.
These tubes can break and lose the liquid, so they can’t illuminate. That leads to dark spots that you can see even at night. And they are signs that you need to hurry up to fix the black spot on the LCD phone screen. This liquid will continue to spill and contaminate nearby pixels, and this spot will get bigger with time. The approximate time of contamination of the whole display varies from 3-5 days to 2-3 weeks. It depends on the size of the amount of spilled crystal liquid. So change your display as soon as possible.
If you face a software issue, you can fix it in 1-2 hours. If it’s some hardware problem, take 2-3 hours out of your schedule. You will need more time to fix a black spot on your phone. In some cases, consider visiting a service center.
If you deal with a software issue, you can quickly remove black spots from the phone screen. Go to Youtube, search for “Stuck pixel fix,” and open one of the videos on this topic. You will see constantly changing colors and shapes: from solid green screen to violet and beige stripes and dots. It helps the phone to hack the mechanism that leads to a stuck pixel.
Turn on the brightness of your screen to the maximum level, lay it on some stable surface, and wait until the video ends. Check out your phone shortly after. This action should help to fix a black spot on your phone.
Try another software hack if you are confident that you have a “stuck pixels” issue. First of all, restart your phone. This action often solves minor software conflicts, one of which is stuck pixels.
If this didn’t help, do the hard reset of the device. It will delete all data and settings from the phone. So don’t forget to make a backup. This action removes corrupted files and major system conflicts.
Find what could be the source of the pressure. If it’s something external, stop using it. Don’t carry the phone in the back pocket. It could lead to a black spot in the corner of the phone because it’s the source of extra pressure too.
If the battery works as it should, the damaged components could be the reasons for malfunction. Find what may cause the problem and replace this piece. If you don’t have the skills, go to the nearest service center. The specialists will advise you on how to remove black spots from the phone screen.
The easiest way to fix dead pixels is to replace the whole screen with a new one. Technically you can replace pixels, but it would be more expensive and time-consuming than just getting a new display. The cost of the screen depends on the phone. Approximately you need to spend $50-150 for the spare parts. If you go to the service center, be prepared for a $50-100 repair fee.
When you see your phone screen turning black, you catch screen damage. Consider buying a new display for replacement. If your phone is still under warranty, contact the manufacturer’s support. Tell them everything about the issue: in some cases, they replace the screen for free or cover a significant part of the repair.
Physical damageIf your device has physical damage, check with the manufacturer. Some manufacturers may exchange or repair your device. Or, if you have an AT&T Pre-Owned device that you bought online from us, and it has a cosmetic blemish, it might be covered.
Otherwise, if your device has any of these types of damage, it won’t be covered by the manufacturer’s warranty. If you return a device with any of these signs, we’ll charge you the total sales price of the replacement device. Plus, we’ll return your damaged device to you.
