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.

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.

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.

Broken screen replacement service is provided from thousands of repairs stores and phone parts wholesalers worldwide, iPhone of which are mostly engaged in. So how to purchase reliable LCD screens among so many quality grades from China suppliers? Let me firstly elaborate on the quality grades of the iPhone LCD digitizer assembly that most repair stores and traders used to replace the broken ones.

According to the investigation, 90% of the Chinese iPhone LCD screen suppliers are found selling third-party manufactured screens and seldom sell genuine original LCD screens. Therefore, if your phone screen is broken, there would be a high chance for your screen to be replaced with a non-original one. Why? Maybe the cost and quality are relatively competitive, so why not?

As known, Foxconn is authorized to assemble iPhone, so there are some original iPhone LCD screens leaked from the assemble factory. And there are brought out from the factory for replacement. However the price is definitely high and still, some people care more about the quality of the screen than how much they cost, so for this group of customers, the Original Quality of LCD digitizer assemblies are preferred.

For some LCD digitizers, the LCDs are still working while the front glasses are broken, which can be recycled. Some factories recycled these broken screens by removing the broken front glass and attach a new one, then the LCD digitizer assembly would be new again, which is what called refurbished. Brand new original LCD screens are limited, and the refurbished ones can replenish the shortage of the new original LCD digitizer assemblies, for their quality would be more stable than the third-party manufactured.

Some Chinese factories purchase the original single LCD display, not compete LCD screen from the original factory, and then attach high copy front glass, backlight, etc, materials into a complete LCD screen, which quality is not stable and the display color is slightly different from the ones with high copy backlight. Well, their price would be cheaper and loved by many repair shops and wholesalers.

Under the shortage of original LCD screens, many Chinese factories begin to produce the high copy LCD screen. The stock and supply are getting less and less since about 2015, which leads the price goes higher and higher. Therefore the Chinese manufacturer starts to produce LCD screens with high copy raw materials. With competitive prices and good quality that meet most iPhone users’ needs, they are also popular among many wholesalers and repair shops.

With the premium quality of LCD and OLED screens tested strictly, we’ve helped many clients enlarge their markets worldwide. If you wholesale the LCD digitizer assembly or retail them in your repair shop, more information and sample are supported for your reference, please do not hesitate to contact us or leave your comment to discuss more.

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.

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.

Sharing her experiences of living in both China and the United States, the author describes how life events have influenced and impacted her social values, attitudes, behaviors, and further discusses how she continues to be resocialized by both American and Chinese societies. She focuses on the connection of those experiences to helping students see a world beyond the borders of the United States. The text presents sociological concepts and theories and lays a foundation on the subject of globalization and offers a comprehensive perspective by which to view other societies. Major topics presented include research methods, including data collection and setting up research projects; a comparison of Chinese and American cultures; new immigrant resocialization; social interactions from society to society; the relative and universal nature of deviance; comparison and evaluation of U.S. and Chinese social stratification; racial group issues; comparison of U.S. and Chinese sex and gender behaviors; different approaches to the importance of family in cultures; the influence of Confucius versus Christianity; population issues, including family planning and abortion; and urbanization and its effect on social change. The book is especially important in the study of history of immigration, world cultures, current American immigration, and the socialization and assimilation by the dominant culture in a society. It serves as an excellent supplementary text for the general study of sociology and social sciences at all levels.

Television is a very intimate object in our daily lives. It not just entertains and informs us about the happenings around us, but it also helps unite families at several houses as we binge on our favourite movies and TV shows together. And despite it being the age of hand-held gadgets, there are still enough people around who prefer television to mobile. No doubt, it feels terrifying when your beloved TV gets a cracked screen.

Though a cracked TV screen is not something that happens so often. But when it happens, not any random mechanic should be assigned the task of repairing it. Instead, only the experts who know the job in and out should be called upon.

Besides, here’re some important things and suggestions, directly from our experts, you must go through before moving ahead on cracked tv screen repair

Firstly, the question is how TV screens can get cracked. Well, there are umpteen reasons to cause this. In most cases, it is accidentally damaged. Your child kicking or hitting at a ball that, unfortunately, lands up at the heart of the TV! Or, the television, placed precariously at the edge of a table, tips over and develops a crack! And at times, you may drop it while either moving or installing it. So it’s advisable to place your TV out of kids’ reach, and you had better not allow kids to play balls in that room. Also, its installation and movement (from one place to another) should be immaculately done, preferably with the help of trained professionals.

Now, the next question is what if your TV screen does get cracked? Is it the end of the story (as some internet articles seem to claim) or you can still get it repaired successfully?

Access the Damage: When a TV screen cracks, there could be several levels of severity and you could be dealing with anything from a completely dead screen to small lines in the picture, and no-picture, no-sound to poor picture quality.

Unless you’re skilled at electronics, you should not try to fix the problem at home, especially if it’s a flat-screen CRT. Most often than not, you end up touching it wrong and are likely to get a serious jolt.

Check Your TV Warranty: A feasible thing to do here is, bring out the papers and check if the TV is still within the warranty period. If yes, then all you need to do is to take the TV to the authorized service centre (Please, make sure to contact the guys only at an authorised service centre to get genuine services). Most probably, you will earn a free repair or a paid repair or a replacement (depends on the reason behind the damage and the sub-clauses in the warranty contract from your TV manufacturer/supplier).

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).

As we can see, the backlight system is made of 5 LED strips. First thing to do is look for burnt LEDs. Most LED backlight systems have strips set in series, meaning that if one of the them fails, all the system goes dark…

Using a multimeter, we can confirm that the strips are indeed set in series, so now we have to test each strip individually. Professionals use LED testers such as this one (about 40$ on amazon) but as I didn’t had one at the time, I decided to make one, McGyver style!
