How to Replace a Laptop Screen

Have you ever dropped your laptop and cracked the screen? Or maybe your screen has some dead pixels or displaying strange colours that make it hard to use. If you’re facing any of these problems, you might be wondering how to replace a laptop screen yourself. 

Replacing a laptop screen is not as difficult as it sounds. In fact, with some basic tools and a little DIY knowledge, you can repair it yourself and save cost. In this article, I will show you how to replace a laptop screen step by step, and what to look out for when dealing with a laptop screen. You will also learn the right tools to use when fixing a laptop, and how to avoid common mistakes that could damage your laptop.

How to check if your laptop screen needs replacement

Before you attempt to replace your laptop screen, you should make sure that the problem is not with the graphics card or the motherboard. A faulty graphics card or motherboard can also cause your screen to malfunction or display nothing at all. You should also inspect your laptop for any other signs of physical damage, especially if it has been dropped or hit recently.

To test if your graphics card is working, you can connect your laptop to an external monitor or TV using a VGA or HDMI cable. Most laptops have one or both of these ports. If the external display shows a normal picture, your graphics card is fine and your screen is the culprit. If the external display is blank, you may need to press a function key on your laptop to switch the output mode. If that still doesn’t work, your graphics card or motherboard is likely damaged and needs repair.

Common Issues with Laptop Screens

Some of the common laptop screen problems include:

  1. Dead Pixels

Dead pixels are tiny dots on the screen that do not change color or brightness. They are usually caused by manufacturing defects, physical damage, or aging of the screen. Dead pixels can be annoying and reduce the quality of the display. There are some software tools and methods that claim to fix dead pixels, but they are not always effective or reliable. The best way to avoid dead pixels is to buy a laptop with a high-quality screen and a warranty that covers pixel defects.

  1. Backlight Bleeding

Backlight bleeding is a phenomenon where the edges or corners of the screen appear brighter than the rest of the display. This is because the backlight that illuminates the screen is not evenly distributed or blocked by the bezel. Backlight bleeding can affect the contrast, color accuracy, and viewing angles of the screen. It is more noticeable in dark or black scenes. Backlight bleeding is a common issue with LCD screens, especially those that use edge-lit technology. There is no easy way to fix backlight bleeding, except by replacing the screen or adjusting the brightness sett

  1. Flickering Screen

Flickering is a rapid and visible change in the brightness or color of the screen. It can be caused by various factors, such as faulty hardware, incompatible drivers, loose connections, power supply issues, or refresh rate settings. Flickering can strain the eyes, cause headaches, and affect the performance of the laptop. Flickering can be resolved by updating the drivers, checking the cables, changing the power options, or adjusting the refresh rate and resolution of the screen.

  1. Screen Burn-In

Screen burn-in is a permanent discoloration or ghosting of the screen that occurs when a static image is displayed for a long time. It is caused by the degradation of the pixels or the phosphors that emit light. Screen burn-in can affect the clarity, color accuracy, and uniformity of the screen. It is more common with older technologies, such as CRT and plasma screens, but it can also occur with OLED and LCD screens. Screen burn-in can be prevented by using a screensaver, turning off the screen when not in use, or changing the wallpaper and icons frequently.

  1. Cracked Screen

Cracked screen is a physical damage to the screen that results from impact, pressure, or bending. It can cause the screen to shatter, crack, or break into pieces. Cracked screen can affect the functionality, safety, and aesthetics of the laptop. It can also expose the internal components and wires to dust, moisture, and electric shocks. Cracked screen can be repaired by replacing the screen or the entire laptop, depending on the extent of the damage and the cost of the repair.

  1. Ghosting

Ghosting is a visual artifact that occurs when the screen fails to update or refresh fast enough. It causes a trail or a blur behind the moving objects on the screen. It is caused by the slow response time or the low refresh rate of the screen. Ghosting can affect the quality, smoothness, and realism of the display. It is more noticeable in fast-paced games, videos, or animations. Ghosting can be reduced by using a screen with a higher response time and refresh rate, or by enabling features such as overdrive or motion blur reduction.

  1. Vertical or Horizontal Screen Lines

Vertical or horizontal lines are thin or thick lines that appear across the screen. They can be of different colors, such as white, black, red, green, or blue. They are caused by various factors, such as faulty hardware, loose connections, corrupted drivers, or software glitches. Vertical or horizontal lines can interfere with the visibility, readability, and functionality of the screen. They can be fixed by updating the drivers, reconnecting the cables, resetting the BIOS, or running a diagnostic test.

How to Prevent Screen Damage 

Your screen can get damaged by many things, like hitting, water, heat, or blue light. To keep your screen safe, follow these tips:

  1. Put a screen protector or a case on your screen to stop it from getting scratched, cracked, or broken.
  2. Do not put your screen close to hot things, like heaters, stoves, or the sun.
  3. Make sure your screen is clean and dry, and do not touch it with wet or dirty hands.
  4. Change the brightness, contrast, and color of your screen to make it comfortable for your eyes.
  5. Use a blue light filter or night mode to make your screen less blue, especially at night.
  6. Update your drivers and software often to make your screen work well and fit with your device.

Essential Tools for Laptop Screen Repair 

Laptop screens are delicate and prone to damage, so repairing or replacing them requires some care and precision. Before you start, make sure you have the following tools ready:

  1. A clean, flat surface: You’ll need a spacious and tidy area to work on your laptop, such as a table or a desk. Avoid working on carpets, beds, or couches, as they can generate static electricity and attract dust.
  2. A magnetic screwdriver: You’ll need a small-head Phillips or Torx screwdriver to remove the screws that hold the laptop casing and the screen assembly. A magnetic screwdriver will help you keep track of the screws and prevent them from falling or getting lost.
  3. A prying tool: You’ll need a thin and flat object, such as a plastic putty knife to gently pry apart the plastic bezel around the screen. Be careful not to damage or scratch the bezel or the screen.
  4. A needle or a pin: You’ll need this to remove the stickers or rubber pads that cover some of the screws on the bezel. Don’t lose or damage the stickers, because you’ll need to put them back later.
  5. A small container: You’ll need this to store the screws and the stickers you remove from the laptop. You can use a small bowl, a cup, or a plastic bag. 
  6. A replacement screen: If you’re replacing a broken or faulty screen, you’ll need to buy a new one that matches the specifications of your laptop model. You can find the model number on the back of your laptop or on the manufacturer’s website. Make sure the new screen has the same size, resolution, connector type, and backlight type as the old one.
  7. A microfiber cloth: You’ll need this to clean the screen and remove any dust or fingerprints before and after installation. Don’t use paper towels, tissues, or other abrasive materials, as they can scratch the screen or leave lint behind.
  8. A light source: You’ll need a bright and steady light source, such as a lamp or a flashlight, to see the small components and connections inside the laptop. Avoid working in dim or flickering light, as it can strain your eyes and cause mistakes.

These are the essential tools you’ll need for laptop screen repair. You may also need some optional tools, such as an anti-static wrist strap, a screen adhesive, or a pair of tweezers, depending on the type and condition of your laptop. Visit Hardware Village to buy all your DIY repair tools. 

How to Replace a Broken or Cracked Laptop Screen

If your laptop screen is broken or cracked, you can fix it by getting a new screen and replacing it. Here’s how you do it:

  1. Get the tools and parts you need

You will need a new screen that works with your laptop model. You can buy one online or at a computer shop. Check the size, quality, and plug of the screen before you buy it. You will also need a small screwdriver, a plastic tool or a thin knife, and a cloth or a towel to keep your laptop safe.

  1. Turn off your laptop and take out the battery and power cord

You need to turn off your laptop and unplug it. Then, take out the battery from the back of the laptop. This will stop any electricity or damage to the laptop parts. You can usually move or push a button to take out the battery, but look at your laptop manual if you are not sure. After taking out the battery, press and hold the power button for a few seconds to use up any power left.

  1. Take off the bezel and screws

The next step is to take off the bezel, which is the plastic part around the screen. You need to use the plastic tool or the knife to gently lift the bezel from the sides of the screen. Be careful not to break any clips or tabs that keep the bezel in place. You may also need to take off some stickers or rubber pads that hide the screws on the bezel. When you have taken off the bezel, you will see the screws that hold the screen to the hinges and the metal part. Use the screwdriver to take off these screws and put them somewhere safe.

  1. Unplug the cable and take off the screen

The last step is to unplug the cable that connects the screen to the laptop. You will see a plug at the back of the screen, usually covered by some tape or plastic. Gently take off the tape or plastic and pull the plug out. Do not pull on the cable itself, as it may break or damage the pins. When you have unplugged the cable, you can lift the screen out of the part and put it away.

  1. Put in the new screen and put the laptop back together

To put in the new screen, you need to do the steps above in reverse. First, line up the new screen with the part and plug the cable to the laptop. Make sure the plug is tight and cover it with some tape or plastic. Then, put the screen in the part and screw it to the hinges and the metal part. Next, put the bezel back on the screen and put back any stickers or rubber pads that hide the screws. Finally, put in the battery and plug in the power cord. Turn on your laptop and enjoy your new screen.
