What Is Required to Fix an LCD Screen Securely?

LCD screens are fragile and very easy to damage, especially on portable devices such as mobile phones and laptops. Moving them around always increases the risk of being dropped. Other damage occurs from bumping screens, spilling liquid on them, or sometimes they just get worn out and the pixels go bad. Since most of these devices are high priced, replacing them is not always an option. Luckily there are a few ways that people can try to do the repairs on their own if hiring someone to do it is out of the question.

It is definitely intimidating trying to fix these oneself because there is always the risk of doing more damage. Owners need to decide quickly if that is a risk they are willing to take. How bad the screen is makes a big difference in that decision. If it is just a few pixels out, then it is probably not worth replacing the screen, but there are other repair techniques to try. If the screen is completely cracked and the picture is now hard to see, then a replacement is the only option. Whether or not owners should do it themselves or hire someone is their choice. Hiring someone costs less than buying a new device, but more than doing a DIY repair. Most repair shops also guarantee their work which gives people a peace of mind. For those who choose to try and fix the screen themselves, a bit of information about the tools needed and the reparations needed is vital.

Check the LCD Guarantee

Before doing anything, make sure the device has no guarantee. If it has one, consider sending it back rather than doing the repair. Guarantees are voided once owners try to fix the product themselves. If their is a guarantee, see what the guidelines are. For example, guarantees do not cover damage caused by the owners. Cracked screens are most likely out of the question. However, if it is a device problem such as bad pixels or an improper seal that lets dirt in, the manufacturer may replace it.

How To Replace TV and Computer LCD Screens

LCD screens on computers and TVs need to be replaced if the screen is fully cracked, liquid was spilled on it, or it was hit with a blunt object. Cracked LCD screens have lines or patterns across the screen, black spots or blotches that occur from the crystals spilling out, or the screen may be totally black or partially black. If liquid was spilled on the screen, there is discoloured light or dark areas. Blunt objects that hit the screen cause a white spot of lightened area. Replaced screens are the only solution to fixing these problems.

What Tools Are Needed

Steps for Repair


Step 1

Turn the power to the device off and disconnect all cables

If there is a battery, remove it as well

Allow the unit to cool off for half an hour before proceeding

Step 2

Locate the screws on the sides or back of the casing and remove them

They may be covered up by plugs that need to be removed

Step 3

Take off the plastic frame and be gentle with it

The frames are harder to replace than the screens

In most cases, the frame is what secures the LCD screen in place

However, there may be a few extra screws to undo underneath the frame to release the screen

Step 4

Remove the damaged screen and put the new LCD screen in place

Replace all the screws on the inside and then screw the frame back on

If liquid was spilled on the screen, there could be more damage

Check and make sure everything is dry and there is no corroding

Step 5

Once fully assembled, hook the device back up to its power source and see if it works

Keep in mind that the LCD screen has to be the right one for the device. Many companies sell replacement screens that are ready to be installed and properly fitted.

How to Fix Scratched TV and Computer LCD Screens

If the screen appears cracked, but the picture is still working fine, then most likely the whole screen does not need to be replaced. Instead, there are a few ways to hide the scratches.

What Tools Are Needed

  • Notecard
  • Clean cloth
  • Vaseline

Steps for Repair


Step 1

Turn the device off and disconnect all cables and batteries

Step 2

Wipe off the cracked area with a damp cloth to remove all dust and dirt from the area

Step 3

Use a cloth to wipe vaseline over the scratch or crack

The vaseline matches the colour and density of the screen, so it fills the crack well

Step 4

Use the notecard to wipe off the excess vaseline and then use a clean cloth to wash off any smudges that are left around the scratch

After completed the scratch should be invisible. Be sure to note that if the crack is large and has chunks missing, this method cannot work.

How to Fix a Stuck Pixel on TV and Computer LCD Screens

There is a difference between a stuck pixel and a dead one. A stuck pixel is usually a colour, while a dead one is sold white or black. If the device is still under a guarantee, it should be covered for either of these problems. If not, the following method may fix a stuck pixel but not a dead one. However, it is worth a try even if the pixel appears dead. It may just be stuck.

What Tools Are Needed

  • Object with narrow end such as a marker or pen cap
  • Damp cloth
  • Hot damp cloth

Steps for Repair


Step 1

Turn on the device

Step 2

Display an image that clearly shows the pixel. For example, if the pixel is white, put up a black background

Step 3

Use the end of a pen or narrow object to press onto the pixel. Try to be as precise as possible so that the surrounding areas are not damaged. Tap the area just hard enough that a quick white glow appears on the screen and then remove the pen.

Step 4

Increase the tap pressure and repeat 5 - 10 times until the pixel appears to right itself

Step 5

If the tapping did not work, use a damp rag and apply the same amount of pressure as before only hold it it there for about a minute

Step 6

If the following techniques did not work, use a damp cloth that is as hot as possible. A microwave is the best way to achieve optimum heat. Wear gloves to prevent burns

Step 7

Place the cloth inside of sealed, clear plastic bag

Step 8

Hold the bag onto the damaged pixel and make sure the bag’s seam is not in the way

Step 9

Now gently massage the pixel in slow circles. This should loosen up the liquid crystals and get them flowing again

If none of these manual methods work, it is possible to purchase software or hardware that can sometimes fix the problem.

How to Fix Mobile Phone LCD Screens

Unfortunately, mobile phones are much more difficult to replace because special tools are needed for each model. However, there are mobile phone repair kits, some of which come with the screen as well as the specialised tools to complete the repair. In some cases, they come with instructions as well.

Find LCD Repair Supplies on eBay

The repair tools needed are specific to each device and in most cases, cannot be found in shops. Luckily, eBay’s thousands of sellers have all the product-specific supplies to browse through. To begin, visit the eBay website and type the specific name of what you need. For example, enter something like “iPhone Replacement Screen” or “PC Replacement LCD”. This should bring up a list of all the products that match your criteria. You can also be more specific and enter in the model of the device that needs the replacement. You may also want to consider getting LCD Cleaning Kits if you are doing the repair yourself.

Since LCD screens are fragile, make sure that the seller guarantees its safe and intact delivering. It is advisable to use a seller who takes extra precautions when packaging the screen for shipment.


No matter which type of screen is broken, it is most likely on a device that is used frequently so a solution has to be found for getting it back into working condition. Owners can check with their guarantee or insurances but if that is not an option, then the choice is between repair it themselves, hiring a repairman, or buying a new product. Depending on the cost of the device, the best option varies. Some of the repair methods are cheap, such as trying to fix a pixel, while others are more expensive and if they fail to work, the owner has lost that money. Consider all the pros and cons of repairing the LCD screen by hand before doing it. For those who decide to continue with the repair, they can do so by following the instructions provided, which are much more simple than people realise.
