how to fix a cracked lcd screen made in china

Mandy, ETS is obviously a company that you are connected to and this could easily be taken for spam. I think we can make an exception at this time since you are asking a good market research question that may be useful to many.

Having checked out your video, I personally will not use the aftermarket screen as a replacement for my X. It just doesn"t have what I expect for a $1000 USD phone. I recognize that $300 USD for a replacement is hefty but the aftermarket screen does not appear to have the quality that I would expect for my phone.

Maybe your significant other tossed your phone off the balcony after discovering flirty texts with a certain coworker, or maybe you were just blackout drunk and dropped your phone on the club’s tile washroom floor while taking a shameless mirror selfie. Either way, your mobile’s glass screen likely looks like a drunken spider’s web.

Luckily for you, smartphone repairs in China are both affordable and fast. But before you venture off to your city’s electronics sales and repair market, we encourage you to browse these six helpful tips for repairing your phone screen:

As with damage to just about any electronic product, knowing the extent of the destruction will go a long way towards ensuring your trusty repairman doesn’t try and pull a fast one by over-quoting or overstating the damage.

In the case of phone glass and the LCD – or more recently AMOLED – screen underneath, it helps to know whether just one, or both, of these elements needs replacing (particularly so you can better estimate the cost).

While broken glass on the front of your mobile is obvious and easy to diagnose, a damaged screen (the part that actually displays all the programs and interface) can be a bit trickier to identify. Look for black spots, discolored areas, new lines and out-of-place patterns on your screen, as any of these may indicate a problem with the screen. Naturally, a totally black screen is a pretty good indicator that something is amiss.

One way to test your screen is to hold down on an app on your phone’s ‘desktop area’ until it starts vibrating, allowing you the move the app to new locations on your screen. Move the app to all parts of your display, if the app is unable to reach a certain area, this is a good indication that you’ll be fixing more than just broken glass.

From our experience, this may very likely be the most important step of all. When having your device"s screen or glass fixed, be sure to show the person doing the repair that all of its key components are in working order. In particular, be sure to demonstrate that both your front and rear cameras work, as well as the speaker and microphone.

We cannot count how many times we have heard of a phone being returned after a repair only for the owner to discover that the phone’s microphone (key for, you know, speaking on the phone) or cameras are no longer working. Also from experience: most repair people are unlikely to take your word that your camera was fine before you handed it over to them.

This should probably go without saying, but here we go anyway: having your mobile device repaired by someone other than a company technician from your phone’s particular brand will likely (like basically 100 percent) result in your warranty being voided.

Not every repair shop will give you the option of watching your phone’s crushed glass be replaced. This is because many smaller shops, particularly in electronics markets, will have your phone sent to an offsite repair area and tell you to come back in a few hours to collect it.

If possible, try and find a shop that will complete the repair in front of you. The main reason we encourage this is because we have heard several unfortunate stories where costumers have had their fully-functioning phone battery swapped out for one that can only hold a two-hour charge. Sad!

The price of having your phone’s glass or LCD screen replaced will depend greatly on the make and model of your phone, the honesty of the person fixing it and – like all things in Asia – your bargaining skills. If your local smartphone repair person wants RMB300 to replace your iPhone 6’s shattered glass, lowball them and offer RMB150. From our experience, repair people seem more inclined to budge on price when it comes to older model phones, meaning your brand new iPhone Xs Plus or Huawei P20 will likely have a higher price point and less discount wiggle-room.

Finding a good repair shop with honest staff who do repairs at a high quality and reasonable price can sometimes be difficult. If you manage to track down a good phone-fixing location, be sure to recommend it to your friends to save them the potentially costly and annoying trial-and-error process when having their glass or screen replaced.

Unfortunately, in most cases, you cannot fix a broken TV screen. TV manufacturers do not sell screen replacements, and there is no secondary market for used screens. That’s because the screen is the most expensive part of the TV, by far. Replacing it would cost more than buying a new TV!

In many cases, your local electronics or TV repair shop won’t even consider working on your broken TV screen. They know that it’s just not worth their time.

If you bought your TV recently, chances are incredibly high that it came from China. Specifically, the BOE Technology factory in Hefei, the capital of China’s Anhui Province.

The BOE factory, where most US TV screens are made today, is almost a mile long and cost about 7 BILLION dollars to build! Sony, Samsung, LG, Vizio, etc. all buy their TV screens from BOE.

“Liquid Crystal display screens are made by putting two thin sheets of glass together. On one of the sheets transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through. That’s how you can get electrical signals to the middle of a screen.

Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts. This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen. Each step has to be precisely aligned to the previous one within a few microns. Remember, the average human hair is 40 microns in diameter.”

This is the number one reason your TV screen is so costly – they are incredibly challenging to build, and as a result there are only a few companies in the world that make them.

I’ve also heard that only 1 out of every 3 TV screens pass testing at the END of the manufacturing process. That means 2 out of every 3 screens made are worthless!

The screens are made in China and then have to be shipped across the world to be sold in the US. The cost to ship them is high, and a lot of damage can happen during the journey.

So the complexity, and shipping both contribute to the high cost of TV screens. It’s why no one sells the screen separately, it just doesn’t make financial sense.

If your TV screen has an imperfection, discoloration, lines, streaks, spots, etc., then there is a good chance that your warranty will cover it (if it’s within the allotted time period). Most TV warranties are in place for the first year, and they cover these types of manufacturer defects.

And the even better news here is thatthe majority of issues you’re likely to encounter with your TV will happen within the first year (when you’re covered by the manufacturer).

You can always try selling it. Your broken TV isn’t worth much, but to the right person, it’s worth something. Someone who knows what they are doing will take your TV apart, and sell off each individual piece.

Technically, you could do this yourself, but it’s time consuming and you risk damaging the parts. I wouldn’t bother. Instead, try listing the whole TV for sale. Getting something for a broken TV it is better than nothing.

If it turns out no one is willing to buy it, you can try listing it on those same marketplaces for free!Tons of people usually respond when they can get something for no cost, even if it’s broken.

Find a local electronics recycler. There are a lot of these out there. You can look up the closest one to you using Earth911’s website. Type in “TV” and then your Zip Code to find the nearest option to you. Once you find the closest location, you just have to drop off your TV.

Local electronics stores typically recycle products that they sell. A great example of this is Best Buy. They have a nationwide recycling program. But keep in mind, they will charge you a small fee!

Your town likely collects e-waste. Check out your town/cities trash website and see what their policies are for electronic waste. Some towns have special pick up days, others have drop off locations. I would just call your city’s public works department and ask for a place to recycle or dispose of old electronics.

Buy a TV screen protector. You can buy a screen that covers your TV and protects it against damage, and many are waterproof! These provide great added protection from possible bumps and contact with liquids from pets and children.

Mount your TV on the wall.This way your television is up off the ground, and out of reach. It won’t stop your kids from throwing a toy at it, but at least they can’t bump into it, or accidentally knock something, or someone into it.

Don’t allow video games. This might sound harsh (especially for the kids), but I’ve heard too many stories of Nintendo Wii controllers being accidentally thrown at the TV. If you don’t hook up a video game console to your TV, this can’t happen.

Most TV repair shops won’t even bother trying to fix a broken screen. In the end, between a screen replacement and the repair costs, you’d spend the same amount for a brand new TV!

If your TV is cracked or damage because of something you did, your warranty is unlikely to cover it. In that case, consider selling your broken TV or disposing of it.

China, we’re told, can make anything. If you need some PCBs in a few weeks, there are a few factories in China that will do it. If you need a nuclear reactor, yep, there’s probably a factory in China that’ll do it because nuclear reactors are listed as one of the items facing new tariffs when imported into the United States. No, I am not kidding. What about LCDs? What about old-school character LCDs? Is it possible to find a factory in China that will make you the LCD you want? That’s what [Robert Baruch] will find out, because he’s repairing an old computer with new parts.

The object of this repair and restomod is a TRS-80 Pocket Computer (PC-1), otherwise known as the Sharp PC-1211. It looks like a calculator, but no, it’s a legitimate computer you can program in BASIC. [Robert] bought this computer for a bit more than $5 on eBay ‘for repair’, which means the zinc-air battery was dead, and unfortunately, the LCD was shot. The LCD technically works, but it just doesn’t look good. Sometime in the last thirty years, moisture got in between the layers of glass, polarizing film, and liquid crystal. This is not unique to [Robert]’s unit — a lot of these PC-1s have the same problem, many of these broken seals rendering the computers themselves useless.

This is an ancient computer, and replacements for this LCD are impossible to find, but because the Sharp PC-1211 is well documented, it is possible to find the datasheet for the original display. With that, it’s just a question of finding an LCD manufacturer that will do it. So far, the costs look good — $800 USD ($300 for tooling and 10 samples, $500 for another 200 LCDs) is what it’ll take to get a few units. [Robert] already has a few people interested in repairing their own Pocket Computers. You can follow the eevblog thread here, or check out the video below.

Chemicals leaking from millions of computer screens in homes, offices and schools could damage human health, according to research by Chinese scientists.

Chemistry professor Su Guanyong and colleagues at Nanjing University of Science and Technology in eastern Jiangsu province studied more than 360 types of chemicals used in computer and mobile phone screens and found that 87 of them could be a danger if they got into the environment.

Some chemicals in liquid crystal displays (LCDs) could alter genes, they said. Animal cells mutated unexpectedly if exposed, and preliminary results of their ongoing study published in Proceedings of the National Academy of Sciences on Monday showed that one of the most polluted places was the home.

Researchers said about a quarter of the chemicals from screens they tested might be pollutants. Photo: Getty alt=Researchers said about a quarter of the chemicals from screens they tested might be pollutants. Photo: Getty

Studies found that excessive radiation from screens could speed up the ageing of skin and blue light from diodes could harm the retina of the eye. "But nobody has looked beyond the brightness to unveil the dark secrets behind," Su said.

Over the years, screen panel manufacturers have pushed LCD technology to higher resolutions and faster refreshing rates, but the chemical composition of the liquid crystal that fills their screens has hardly changed.

Su and colleagues produced a list of chemicals used by manufacturers and found that 87 " about a quarter of the substances tested " might be "persisting organic pollutants" that were not only harmful to health, but their composition meant they would take years or sometimes decades to decompose. The exact effect of these chemicals was unknown.

They exposed embryonic chicken cells to liquid crystal taken from the screens and compared them to cells grown in normal conditions. They found genetic changes that suggested the exposed cells had mutated.

"Our laboratory has tested a large number of toxic substances. This [effect] is similar to the exposure of other known persistent organic pollutants," Su said.

The Nanjing team was baffled by the amount of liquid crystal in the air. They knew screens were made in dust-free factories and sealed, but their surveys of hotels, school buildings, canteens, dormitories, electronic product repair centres, homes and laboratories revealed surprising results.

The lowest levels were found in a canteen, a dormitory and classrooms. Su said they were not sure where the drifting liquid crystals came from. Some screens might have been cracked or broken, he said. If a screen was left on for a long time, heat and radiation might cause liquid crystal to evaporate.

There was no solution to the problem at this stage, the researchers said. To push the government for more strict regulations meant that the scientific community had to come up with more evidence and a better understanding of the problem.

"Electric device recycling plants could be a major source of emissions, with broken screens dumped everywhere and little protection. This practice must stop," he said.

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 relatively easy and cheap to replace the glass on a phone once you get the hang of it. Tablets are a bit more involved because of the larger size and added components.

Tools might require an additional monetary outlay if you do not have a well-functioning workbench. Depending on the device involved, you need a phone opener pry tool, little tweezers to deal with small cables inside, a Torx screwdriver, flat-head screwdriver and a precision screwdriver kit.

Add to that list either a variable hair dryer or a heat gun to soften glued phone parts. Also add scissors, double-sided adhesive tape, canned air and work gloves.

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.

The coating, a thin layer of fluoropolymer-based solids, is similar to Teflon and is bonded to the glass. You can buy the coating kit from a variety of electronic supply stores and online outlets.

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.

Does using toothpaste to fill in the cracks really work? I put that fix in the category of more “mythful” thinking, but I know people who swear that this method is a cheap fix that works.

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.

Before you roll up your sleeves to get started, take one huge safety step. Buy and use a static wristband and a static guard mat. This will ensure against accidentally frying any electronic components while disassembling and reassembling the devices. Disconnecting the battery is not always a guarantee that static discharge will not happen.

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 2: Loosen any stuck-on cabling that is now exposed, like the camera cable. Then remove cables if the clasps are exposed. These cables simply slide out of any exposed sockets after clasps are released. The tape-style cables are often held onto the frame and parts by adhesive, so tug gently to release.

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 4: Remove any further cable assemblies that have become exposed by the separation of parts. Maintain visual cues as to which cable to reattach where. For example, place them on the work surface face-up in the order of removal. Or take photos with a digital camera or smartphone.

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.

Tip: Be patient while the heat gun loosens the adhesive and be careful not to break the bezel or front frame while removing the glass. You need the bezel intact.

Step 1: Attach fresh two-sided tape to areas of the bezel that have lost their stickiness. Use the existing adhesive where possible. Do not allow tape to overlap the visual part of the glass.

Step 2: Look for any foam padding or seals and reattach. Do not touch the inside of the glass. You won’t be able to get rid of the fingerprints after assembly.

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.

You may have to assemble and disassemble a few times. The two sets of screws use similar holes. It is easy to insert the initial set of screws into the wrong holes. You will realize that only when the second set does not fit because you already used the hole.

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.
