lcd screen deep scratch repair made in china
The old way to refurbish the screen and back glass is to replace the front glass and back glass, which is not only difficult and costly but also less efficient. The grinding and polishing machine recommended this time is specifically designed to solve this problem in refurbishment. For the front and back glass with smaller scratches, the grinding and polishing machine only needs 3-6 minutes to complete refurbishment while bigger scratches require 8-12 minutes, which shows great power in refurbishment.
The grinding & polishing machine is used to refurbish the phone screen, back glass and apple watch screen. Refurbishing the screen and back glass is a necessary step for refurbishing factories and pre-owned phone recycling companies.
Magic erasers are usually used for cleaning up messes, but could they clean up scratches? Yup. It wiped out small scratches on the phone"s screen in just a few seconds. Taylor Martin has a tutorial on how to make your own magic erasers for just around $0.10 (£0.07 or AU$0.14) each.
Wiping a screen with toothpaste (not the gel kind) supposedly works for fixing scratched screens. All it did in my tests was make the screen shinier and seemed to add small abrasion marks. I also tried toothpaste on a plastic screen protector, such as the kind that comes with OtterBox phone cases. It worked great on that! So it"s a no for screens, but a yes for plastic screen protectors.
Erasers work great for making scratches disappear. I used a white rubber eraser, but you can also use the type that"s found on the end of a pencil. Simply rub the scratch left and right with the eraser for about 60 seconds, and then rub it up and down for 60 seconds. The friction softens the eraser and it fills in the scratch. Don"t press down too hard, though!
Car waxes and headlight lens creams are supposed to be effective at removing scratches on screens, so I gave Mothers PowerPlastic 4Lights headlight cream a try. It made the scratches fade significantly, and l liked the shine it gave my screen.
A paste of two parts baking soda to one part water has been bandied about as a great screen fixer. Nope. It just made the screen really shiny. Plus, the moisture in the paste could damage your device.
According to the internet, coconut oil can solve just about any problem. Shockingly, it didn"t work well on phone scratches. Like with the petroleum jelly, it just made the phone super slippery.
I wasn"t sure about this tip. Sites say to mix the corn starch with a little water to make a paste, rub it on the screen with a soft cloth, and then wipe it off. It didn"t do anything to the scratches, but it made the screen shiny.
OK, this one freaked me out. A lot. Putting gooey, oily stuff on electronics is never a good idea, but I gave it a shot in the name of science. I dabbed a bit on as recommended, and rubbed it into the screen with a tissue. As I feared, all it did was make the test screen oily and sticky.
Why do people think it"s a good idea to rub food on their phones? Nope, rubbing a banana peel on your screen won"t help it. I tried it a couple different ways and it just left a crusty mess that is hard to remove.
Powdered cleanser like Bar Keepers Friend, Comet, Ajax and the like seem a good idea for buffing out scratches. They are slightly abrasive, so you"d think they"d polish your screen to a gleaming scratch-free shine. Well, they don"t. They can even leave new little scratches on your screen. Yah, this test didn"t go well.
There’s nothing quite as frustrating as pulling out your phone to use Face ID only to find a fresh scratch getting in the way of your phone screen and reflection. (Well, other than whenFace ID stops workingentirely, or theentire screen is cracked).
Not only are these scrapes bothersome, but they make it challenging to see the display and can even interfere with touchscreen capabilities (if they’re deep enough). So, how can you fix these phone screen scratches?
There are several options available. Before you doanything, however, be sure to power off your phone and avoid getting any liquids or debris in the device. It can cause harm if you don’t follow theseprecisely, leaving you with more damage to fix. Let’s look at the best – and worst – bets when it comes to fixing phone screen scratches.
A simple Google search for how to fix a scratched cell phone screen will yield several results, but the most interesting and common tip we’ve come across? Toothpaste.
Cheap and easy to find, toothpaste seems like a magic fix that’s too good to be true. Well, that’s because it is. Most tests reveal that using toothpaste results in a squeaky clean but still scratched screen. That is unless you’re trying to buff scratches out of a plastic screen protector or case, as many people do experience some success there.
With glass, however, that isnotthe case. In fact, you may even make your screen even more smudged, forcing you to use some elbow grease to get it out. (Particularly if you use something stronger like, say, AquaFresh.)
While it never hurts to try, just set your expectations low. If you’re feeling adventurous, use toothpaste like Colgate or Crest and not anything gel-related. Just apply the paste to the scratch with something soft like a cotton swab or cloth and rub it in.
Forget the delete key, rememberMagic Erasers? Back in the day, they were known to get rid of stains all around the house. But, surprise, they can actually eliminate phone screen scratches.
However, just remember that they remove them as long as the scratches are small and shallow. While deep abrasions are untouchable by the eraser, surface-level cosmetic scratches buff away pretty quickly. It never hurts to have one around, just in case.
Baking soda mixed with water is touted as a quick fix for phone screen scratches, but does it work? Thanks to its similarly abrasive nature, it turns out that this method is about the same as toothpaste as far as results go.
It’ll take care of marks decently enough on plastic covers and screen protectors, but definitely not glass. The Internet will tell you to make the baking soda mixture and then gently apply it to the screen, rubbing it in a circular motion. Afterward, you might notice that your screen is shinier, but chances are that the scratches will most likely remain. So unless you have a plastic screen, look elsewhere.
If a product can get scratches out of the body of your car, then logic clearly dictates that it can fix up your phone screen, right? Even though it’s a different material, you might be surprised how well car polish can work!
Depending on how deep the scratches are, this method is actually pretty effective. Products likeTurtle Wax,Meguiar’s Mirror Glaze Swirl Remover,3M Scratch Remover, and more can all help get rid of fine cuts on your phone screen. Just follow the instructions on your chosen product and imagine you’re buffing out the scratch your high school-ex left when they keyed your first car. (That’s not just us, right? Um, right?)
Another common fix touted all over the Internet is to use silver polish for your phone. I know what you’re thinking: If it can work wonders on my Nana’s heirloom silver, it’s obviously good enough for cell phone screen scratches. Right?
Wrong. Dead wrong.While products likeSilvo,Brasso, orWeimansilver polish can get tarnished metal shining like new again, it can do a number on your device. Not only is the method not proven to work, but it can also damage the coating on your screen, making the matter much worse. In this particular case, all that glitters is not silver.
Let’s be honest – sometimes home remedies can only do so much to fix your phone screen scratches. Want to bring out the big guns and spend a bit more money? Have your carrier or the phone’s manufacturer replace the screen altogether.
Apple offers repairs for $29 for cracked screens withAppleCare+(or up to $149 if you’re out of warranty). A third-party repair can be cheaper, or you could buy a kit online for around $60 to tackle shallow scratches. You get what you pay for here, and without having to pour some weird substance over the surface of your phone.
(One quick side note. Due to COVID restrictions, it may take you a little longer to take your phone into a Genius Bar for repair. If you have the option, send it in instead. Who knows, Apple may even send you a replacement in its place, depending on your coverage plans!)
If you don’t want to risk further phone screen scratches by using the above methods and you’d rather not spend the cash on having it professionally repaired, you can always cover scratches using a screen protector. While this won’t remove or reduce the visibility of deep scratches, it will help you avoid doing further damage to your phone. So it won’t fix the problem, but it’ll keep it from getting worse.
If push comes to shove and you just can’t live with a scratch, there is one more very highly effective step. Purchase a new phone and sell your old one to us!
If you’re tired of looking at all the knicks and dings on your device’s phone screen and it’s time for an upgrade anyway, consider selling your phone to us here atGadgetGone.
From there, you can buy a new device and you’re good to go. That said, make sure you take protective measures next time, so you don’t get a scratch. Because, then, you might just have to repeat the process.
We hope these methods (well, most of them, anyway) guide you in getting rid of those bothersome scratches. Now, as far as those dents in the Ford Mustang in the parking lot…you’re on your own.
Cracked or broken mobile device screens can be costly to fix, but a few inexpensive do-it-yourself strategies can eliminate a repair shop visit and salvage your tablet or phone.
Third-party repair shops typically replace glass on a tablet for about US$100-$200, depending on the model. Replacing the tablet’s touchscreen can cost $50-$75 extra.
Replacing the cracked glass with a functioning touchscreen is much cheaper. You usually can find suppliers online for $6 to $20 for a phone. A tablet replacement digitizer can cost about $50 or more if you perform the work.
It is first things first when it comes to fixing cracks on a smartphone’s screen. Often, the actual screen is not cracked at all. You may have installed a glass screen protector when you purchased the phone.
The film covers can become cloudy or scratched. They usually help absorb shock from items dropping on the tablet to lessen risk of cracking the touchscreen glass under it.
When the culprit really is a damaged screen, choosing one of the next three approaches can help you solve the problem. You might be able to repair the damage rather than replace it.
For instance, is the screen clouded or otherwise damaged from your mistaken use of harsh cleaning fluids or coarse paper towels to clean the screen? If so, there is a fix for that.
Is the screen merely cracked or full-out broken — as in massive spider cracks from being smashed? You can cure a cracked screen on a phone or tablet more easily with Sugru, a commercial product. A fully cracked screen on either type of device is a solid candidate for a screen replacement.
If your phone or tablet screen shows signs of cleaning abuse or wear from heavy handling, return its condition to nearly new with an oleophobic coating kit. This is an oil-repellent coating that protects the screen, along with adding smoothness and reducing fingerprints.
Prepare a wiping finger. The oleophobic coating’s liquid solvent evaporates very quickly when applied, so once you start, work quickly. Wrap one finger with plastic wrap or a sandwich bag. Use this finger to rub the coating liquid onto the screen.
Apply 10-15 drops of the coating to the screen’s surface. If the phone or tablet screen has a large surface, apply 10 drops to a portion of the screen, working on one portion at a time.
Wipe the screen dry with a clean microfiber cloth. Then give the coating time to dry. Do not touch the screen for 8-12 hours to allow the coating to bond to the surface.
If your only complaint involves tiny scratches and cracks on a smartphone screen or a tablet glass, there are remedies that work with varying degrees of reliability. You can use a household eraser pad or an actual pencil eraser.
Pencil erasers also work reasonably well in making scratches disappear. Simply rub the scratch left and right with the eraser for about 60 seconds. Then rub it up and down for 60 seconds.
Sugru is a moldable glue kit for repairing rather than replacing cracked screens. Actually, the product was not created with phone and tablet repairs in mind. Its intended purpose is more in the line of general repairs where bonding surfaces together and filling surfaces are needed.
Depending on how badly the screen is damaged, it can be a good solution for cracks that spread from the phone or tablet screen’s edges. However, for massive cracks that spread over the entire screen — as spider cracks tend to do over time — it will be a short-term fix at best.
If your phone or tablet screen has suffered more serious damage, full scale surgery is the only option other than getting a new device. Repairing the device’s LCD screen is a complicated procedure due to the compact internal design.
The repair process involves completely dismantling the phone or tablet’s outer casing. It is particularly easy if the replacement screen comes with a top frame.
Otherwise, you may have to seal the layers to avoid loss of structural strength and moisture/dust protection. You can use either sealing pads for the size of the particular device at hand or double-sided sticky tape. A simpler solution for phone screen replacement is to use B-7000/T-7000 glue.
The first step is to tear down the device so you can assess the extent of the damage and determine what screen parts to order. Locate the model number for the LCD screen. Use this number in an Internet search to find a replacement screen.
The part or model number usually is printed on a label adhered to the sensor cable attached to the screen. You can access this cable after you separate the screen from the rest of the unit. Carefully disconnect the cable connector from the backside of the screen along the edge.
Step 3: Unscrew the Phillips or Torx screws that hold the motherboard-containing back frame to the LCD-containing chassis and place the screws in a bowl for safe-keeping. Then separate the back frame from the chassis by gently and carefully pulling the two apart.
Step 5: Remove the LCD-containing chassis from the front frame or bezel and glass assembly by unscrewing a second batch of screws. Store the second set of screws in a second bowl. Remove any further parts such as the camera.
Step 6: Don’t touch the LCD face. Separate the existing, damaged glass from the bezel or front frame by waving the heat gun over the adhesive join and pulling apart. Wear gloves here because the process involves further breaking the glass.
Step 3: Thread the digitizer cable and remount the new digitizer glass to the bezel by firmly pressing it into place. Then remove any dust from the LCD and glass with canned air.
Replacing damaged touchscreens and digitizer panels is not rocket science, but the process does require careful attention to details. Following visual guides and screenshots can make the difference between initial success and having to make second or third efforts.
Scratches on your phone screen can be a sore sight for the eyes. Getting them removed from your phone could also be tricky. The first step to take is knowing what to do, before you remove scratches from phone screen. Before selecting a method to remove scratches, firstly find out from your phone manual, the sort of material your phone screen is made from. If it is not indicated in your manual, you could check for it online, by entering the full name of your phone model in a search engine. This will enable you to know what substance you can or cannot use on your phone screen. When this information has been obtained, you can try a total of 9 solutions to remove scratches on phone screen no matter you use a glass phone screen or a phone screen protector.
Replace the screen guard if it was removed, when cleaning with the cloth. Replacement of the screen guard can be done at any service center. Please remember that this is a chargeable service, and you will need to pay for it.
This is usually used as a coating but can serve in hiding scratches on your phone screen. Preferably used to remove scratches from the phone screen protector
Also not a permanent solution. Used for very minor scratches that can be easily hidden. Apply a little oil on a cotton swab or lint-free cloth, and rub gently over the scratch. Use a dry cloth to wipe off any oil residue.
There are other options such as the combination of egg white, and aluminum sulfate to remove scratches from phone screen, but the procedures for combining both substances to obtain a Polish is quite tasking, and time-consuming. It is highly recommended that other readily available options be sorted to. There is also the option for the use of car scratch removal lotions, but several reports have indicated that it may not be safe to use on phone screens, considering the fact the phone screens are made differently from car screens.
When trying these screen scratch remover options above, if it doesn’t yield the results you want, you may need to find a professional phone repair provider.
Carlcare services is a very good option if you are considering where to go to. It is the official after-sales service center Infinix , TECNO, and Itel phones. If there are scratches on your phone for these brands or the phone screen is cracked, you can take the phone to the Carlcare service center to fix scratches on phone.

I ordered a replacement screen from China on eBay. I followed this write-up to disassemble the screen unit from the car, then disassembled the electronics from the screen (no biggie) plugged the FRESH new screen into the circuit board, replaced the metal protector and connected it back to the plastics, reinstalled it into the car, and voila, totally fresh new screen. Total time. 20 minutes to remove from car and check to make sure it was part number LQ088K9LA02, 2 weeks wait to receive the part from China. Then about 1 hour to remove and replace the screen. Perfect replacement, perfect fit, really pretty easy job.
Display a black image, which will show the stuck pixel very clearly against the background. (It is very important that you are showing a black image and not just a blank signal, as you need the backlighting of the LCD to be illuminating the back of the panel).
Display a white image (an empty text document, or sending your browser to about:blank and going to fullscreen with F11 is good for this) to verify that you haven"t accidentally caused more damage than you fixed.
This method is useful if large areas are discolored or even black. It works best with laptops, but it may work with separate monitors, too. By using this method, you are exposing your computer to the risk of damaging the processor and/or other components by overheating. If you do this, you should be willing to accept the loss of your computer (for laptops), or monitor (for stand-alone screens). You should backup your data before trying this method. In particularly bad cases of damage, the effect may not work completely, or the fix may not be permanent.
Close the laptop lid almost completely, but don"t let it close fully - This will keep the laptop screen turned on indefinitely. You may take a small paper pamphlet or something soft and place it on the keyboard to prevent gravity from closing the lid.
LCD displays are composed of multiple layers. Each layer is separated by very small glass spacers. These spacers and the individual layers are very delicate. Rubbing an LCD panel with a finger or even a cloth can cause the spacers to break and cause further issues beyond the original pixel fault. As such, most repair technicians with service certifications are trained not to use the rub or tap methods - use them at your own risk.
Most LCD manufacturer warranties for LCD displays will cover replacement of the panel when the display reaches a certain number of pixel anomalies. These warranties, however, generally will not cover damage caused by rubbing the screen so use extreme caution and contact the manufacturer before proceeding to see if you qualify for repair or replacement.

Ever had your TV showing nothing but a black screen even if the audio was working? Unfortunately, that’s a common issue with low/middle-end LCD/LED TVs these days… Even more frustrating, this issue often comes from a rather tiny and cheap component that can be easily replaced. Most common issues are:
One of my relatives had this exact symptom happening all of a sudden. This problem on low-end TVs often occurs within the first couple years. As the repair costs for that kind of TV is pretty low, considering repairing it yourself might be a good idea!
The first step into repair is to find the root cause of the issue. As backlight failure is a very common issue, this is the first thing to test. To do so, the easiest way is to power on your screen, put a flashlight very close to it and check if you can see the image through. The image would be very dark, like turning the brightness of the screen very very low.
That implies disassembling the TV to access the backlight which is between the LCD screen in the front and the boards in the rear. In my case, with a Samsung F5000, I had to process as follows:
First we have to remove the back housing to reveal the boards (from left to right: main board, T-CON, power supply) and disconnect the LCD panel from the T-CON board.
Note: Older TVs have neon tubes for backlight, which is thicker and less exposed to this kind of failure. LED backlight is the most common thing these days, but do not mistake an LED TV with an OLED TV. The first one is a classic LCD panel with a LED backlight, whereas the second is an OLED panel that doesn’t need any backlight as it is integrated in each pixels (making the spare parts much more expensive by the way).
There might be a lot of other root causes for similar symptoms, a black screen often looks like something very serious and therefore expensive to repair, but this case is the perfect example that taking some time to look for the root cause can sometime lead to a good surprise: here a 1$ fix!
“Original” screens are those containing LCDs manufactured for Apple. “Copy” screens are compatible replacements entirely designed and manufactured by third-party companies not associated with Apple.
LCD display panel can have poorer resolution (i.e. looks “coarser”), worse brightness, contrast and vibrancy and reduced refresh rate amongst other problems.
Changes in specification from original can result in battery and performance issues. Certain badly-engineered screens could even damage the backlight circuitry.
Customers who bring their iPhones to us for a screen repair are offered two choices of replacement- an original or a “copy” screen. The most common response is “Is there a difference- and which one would you recommend?”
Originals are those screens containing LCDs that were manufactured for Apple. So-called “copy” screens are compatible replacements, but designed and manufactured entirely independently by third-party companies, typically in China.
Our answer is simple- the original screen is the one we’d go for ourselves, every time. Some people think we make more money on them, but this isn’t the case. We recommend originals because they’re far higher quality and the price difference is fairly small.
We’d rather only fit original screens. The only reason we don’t is that many people will shop around and choose purely on price. As such, we need to offer the cheaper copy screens to remain competitive and avoid losing these customers. In some cases, they didn’t even know there was a difference in the first place- especially since it’s not in some shops’ interest to draw people’s attention to the issue!
This may well be the worst copy screen we’ve ever come across. As a result, the unfortunate customer has ended up paying twice to have their screen replaced- we’re sure that had they been properly informed, they would have chosen an original in the first place.
While the difference in price between copies and originals can vary across devices, it’s generally around £10 – £14 extra to have an original screen fitted. This really isn’t a lot considering the improved quality and reliability.
We compare our prices to our competitors- and we know that we come out of it favourably. While we have to offer copy screens to remain competitive, we always advise customers to go for the original.
When you’ve spent- directly or indirectly- several hundred pounds for an iPhone with a Retina display, it doesn’t make sense to replace it with a lower-quality screen that can make a £400 phone look like a £40 one! Not only that, but you’re likely to have fewer issues, and a longer-lasting screen.
There’s nothing stopping any random person without training or experience opening up a smartphone repair shop. As a result, the industry is full of companies with little skill or experience who are only interested in getting hold of your money and installing the cheapest parts they can find.
Many- if not most- don’t even acknowledge the existence of copy screens, let alone explain the difference to the customer. Hardly in their interest to do so if they only fit cheap, low-quality copies. Some of them can hardly be blamed- they know so little, they’re not even clear on the differences between OEM, non-OEM and copy displays themselves! Others can be more deliberately misleading… and some outright lie.
Generally, these shops are looking for the cheapest price on replacement screens.. When offered a copy at a half or a third of a price of the original, they’re going to go for that. That might be fine if they offered the customer a cheaper price- what we disagree with is selling “supermarket beans” (i.e. the copy screens) at “Heinz beans” prices!
Heading towards the “blatantly fraudulent”, we’re aware of companies that shamelessly fit copy screens while claiming them to be original. Worse, they’ll take your broken original screen and sell that to a recycler for more than they paid for your copy!
Apple tightened up their supply chain around 2015, which reduced the number of screens available for repairs and increased their price dramatically. A lot of companies went bankrupt, and Chinese manufacturers responded by making their own “copy” screens from scratch. At first, these weren’t much cheaper than the Apple ones, but the price soon fell.
We should be clear that- despite the name- “copy” screens aren’t direct copies of the Apple originals. Rather, they’re compatible replacements that have been designed from scratch and- as a result- vary in some respects that have an effect on usability and quality.
One of the most important differences between an original and a “copy” screen is how the digitizer (touch sensor) is designed. Apple has it manufactured as part of the LCD itself, whereas the copies have it on the glass.
Although there are only a small number of manufacturers of the bare LCDs themselves, these are then bought by countless other companies who add the remaining components needed to turn these into a complete working screen. As a result, you could easily end up with an LCD from the best “copy” manufacturer, but the digitizer/touch (as part of the separately-manufactured glass) from the worst.
There are countless digitizers out there, and you can only take the supplier’s word that the quality is good. Many ship good ones at first, then switch to cheaper parts to make more profit. This is particularly bad with the iPhone 6S and 6S+, since Apple moved the chips responsible for touch processing onto the LCD itself. As a result, you’re not just getting a copy screen- you’re getting copy chips too.
The performance specification (power drain, etc.) of most copy screens isn’t identical to the originals. As a result, they can drain the battery more quickly and mislead the operating system which was optimised for the original screen design.
It’s even possible that this mismatch could damage your backlight. We do a lot of subcontracted repairs for less-experienced shops, and get backlight repairs in almost every day. We’ve had cases where we fixed the circuit, fitted the new copy screen to test it, and had it break the circuit again!
Copy screens can disrupt the touch ID fingerprint reader. With the 6S, 6S+, 7 and 7+, the home button- part of the 3D touch- is part of the screen assembly. Frequently the home button flexes on aftermarket designs don’t work properly and stop the touch ID working- annoying if you use it to unlock the phone or log in to your bank.
We’ve seen many lift away from the frame that holds them in place. This usually results in the flex cable getting torn, and the screen needing replacing. You don’t even need to have dropped the phone- this often happens through general everyday wear and tear.
That brings us to another major issue with the copies. When you drop an Apple original, the glass often breaks, but if the LCD itself is intact, you can continue to use it until it’s fixed. With the copies, the touch/digitizer is on the glass and stops working when that’s broken. Even worse, the LCD itself is more likely to break due to the thinner and more fragile glass.
We’re not convinced this will happen, since Apple recently changed their repair policy to accept iPhones with third-party screens. However, it is possible that copy screens could be stopped from working via an iOS update, since those make a number of security checks.
