As mobile phone displays are much tougher than they used to be, it seems like they"re indestructible. Sadly, they"re not. Dropping your phone can often break the display. Your phone can no longer be considered useful.

Cracked your mobile phone display? Dropped it in the street, or crushed it playing football? Sat on it, even? You know by now that you"ve given yourself a headache. Can the phone be repaired, and if so, what are the costs?

Many services available online and locally will repair your mobile phone, for a price. But if you have access to the parts and they"re inexpensive, why not perform the procedure yourself?

You should also consider the non-monetary costs: time spent without a phone, data that needs archiving from the device. Hopefully your mobile platform"s cloud service can help here, or perhaps a desktop utility can check the phone"s contents.

Fitting a new display that costs the same as a replacement phone is pointless. However, if replacing the mobile phone screen is closer to $15, it makes sense to have a go yourself.

The most obvious location for a replacement display is eBay. Simply searching for the mobile phone model and the word display will turn up the required parts. Just remember to shop safely when using eBay.

In my case, "nexus 5 display" returned a wealth of accurate (and, sadly, slightly inaccurate) results. Take the time to check that the component you choose is genuinely for your device. Often, components may appear in the results thanks to a poorly written listing.

Amazon is also a resource for replacement screens, but you should also consider a general Google search as this will turn up specialist suppliers who might be able to provide a lower price.

Note that you may find listings that offer just the display, versus listings with half the phone"s chassis. Which one you buy depends on how complicated you want things to get. For example, just the display means melting the adhesive using a heatgun or hairdryer.

Alternatively, a replacement display kit that includes half the phone"s body will require components being transferred from the old body into the replacement.

These tools are included to remove the case and unscrew any components that obstruct replacing the display. For example, a mobile phone will have Torx screws under the battery cover that will need removing before you gently prize the case apart.

Note that spending money on these tools isn"t totally necessary. Sanding off the ends of a couple of plastic bicycle wheel levers will produce usable alternatives---otherwise, they can be sourced relatively cheaply.

There are so many different mobile phone models on the market (either new or used) that providing a standardized guide is next to impossible. Additionally, some models cannot be repaired without sending them back to the manufacturer.

To begin, remove (where possible) the rear cover, battery and identify where the Torx (or standard) screws might be hidden. Look under labels and beside USB ports. You might find screws in the battery cavity if you have a device with a removable cell.

These are often threaded through the different layers of hardware within the phone. Ribbon cables are delicate; easily broken, take care as damage to these could change the dynamic of the repair considerably.

Persuading your phone"s display to part with the body isn"t usually difficult. Pushing through the camera hole against the glass to begin with, slowly prize the glass display away from the body.

In this case, you won"t need to remove the display, but you will need to remove components (and even the motherboard) from the damaged device into the new body.

Narrow rolls of replacement adhesive can be bought online. Have some double-sided sticky tape laying around? Cut this into narrow 1 mm slivers, then apply the adhesive to the phone"s frame, rather than the glass.

Apply light pressure where the display meets the adhesive. Take care not to put pressure on the middle of the glass display. Excessive force can break even the strongest Gorilla glass.

Reconnect the relevant cables, locking them down where necessary. Place the components back in the case with care, checking that there are no cables or screws left over. Test the phone to check that it works.

The moment of truth: does the new screen work? Remember, a touchscreen display has two purposes: touch interaction, and displaying the phone"s operating system.

However, it isn"t always plain sailing. I"ve fitted a replacement display that caused the phone to overheat. Therefore, it is important to buy components from reputable sellers, and ensure you"re buying the right parts for your phone.

Most importantly, don"t walk into performing such a repair without some device-specific research first. Video guides are particularly useful; once you"re ready, get hold of the right tools and surprise yourself!

Here"s another tech problem you can solve yourself with a bit of time and effort: phone display flickering. And if you drop your phone into the water, don"t panic, follow these tips to help save it.

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!

Whether it’s cracked or has one too many blown pixels, a broken laptop display can stop you dead in your tracks. But with the right tools, a little technical know-how, and a bit of patience you can replace a damaged LCD.

Note: In this article and video, I show you how to replace the screen on an Asus UL50V notebook, which has an LED-backlit LCD. Depending on the make and model of your laptop, the internal hardware and specific steps may vary. The general process however, should be the same.

I also suggest you watch my earlier video on what to know before trying to fix a smartphone or tablet. It’s not specifically about laptops, but the information is still relevant, and it will help you decided if you should repair the machine yourself or take it to a shop.

Lastly, understand that if you follow the instructions in this video, you do so at your own risk. Neither CNET nor any of its representatives can be held responsible for injury, damage, or loss of data.

To begin your fix, you’ll need a few simple tools and a replacement LCD screen. For tools, I recommend a screwdriver with a variety of small bits, such as a Phillips #00 and a Torx T5. It’s also a good idea to have a few thin metal blades or plastic spudgers. These are really handy for removing the trim that surrounds the screen.

As for the replacement LCD, you should be able to buy one either from the laptop manufacturer’s authorized parts dealer or a third-party supplier. Depending the screen, they usually cost between $50 and $250 dollars–more if it’s a high-end display or you buy an OEM replacement. Regardless, you’ll want to buy a new screen that matches your broken one exactly. The only sure way to do this is to remove the broken one.

After disconnecting the power supply and removing the battery, carefully examine the bezel around the screen. You’ll need to remove this bezel to access the screws that hold the LCD panel in place.

On this laptop, several rubber cushions hide screws, which hold the bezel in place. I’ll need to remove these cushions and the screws that are underneath.

With the hidden screws removed, I used a thin metal blade to pop loose one of the bottom corners and worked my way around the bezel with a plastic spudger.

Note:Your laptop may not have cushions or hidden screws. The bezel may simply snap onto the lid or be held in place with double-side tape. Just, adapt my instructions to fit your specific laptop.

With the LCD’s mounting brackets exposed, you can remove the screws that secure it to the lid. Then rest the display front-side-down on the case and disconnect its cable.

If your laptop was made before 2010 and has a LCD with fluorescent backlights, it will likely have two cables. But as this is an LED-backlit LCD, it only has one.

Now, locate the manufacturer’s label and note the model number. Using this information you should be able to buy an exact match for your broken screen.

If the dimensions, mounting brackets, and connector all match, you ready to install the screen. Connect the new panel to the cable, position the panel in the lid, and secure it using the appropriate screws.

Before reattaching the bezel, it’s a good idea to test the new panel. Reconnect the battery and power cable and turn the machine on. If the display works, you can reattach the bezel and any external screws and rubber cushions. The repair is now complete.

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.

Apple has determined that, under very rare circumstances, a crack may form along the rounded edge of the screen in aluminum models of an Apple Watch Series 2 or Series 3. The crack may begin on one side and then may continue around the screen as shown in the images below.
