Laptop screens can easily get damaged from drops, impacts, or excessive pressure on the display. A cracked or broken laptop screen can make it difficult to use your computer. Thankfully, with the right tools and replacement parts, repairing a damaged laptop screen is a DIY project that most people can tackle. This comprehensive guide will teach you everything you need to know to successfully replace a broken laptop screen yourself.

Assessing the Damage

Before replacing your laptop screen, you need to thoroughly assess the damage to determine exactly what needs to be repaired or replaced.

Types of Laptop Screen Damage

There are several common types of laptop screen damage:

  • Cracks or breaks in the actual display panel
  • Broken or cracked bezel (the plastic frame around the display)
  • Faulty video cable connections
  • Issues with the LCD backlight

Carefully inspect your laptop screen and identify what type of damage has occurred. Cracks, breaks, or dark spots in the actual display will require replacing the entire display panel. Damage to the bezel or video cables may just need minor repairs. Backlight issues could need a new inverter board or display panel.

Determining the Replacement Part Needed

Once you’ve identified the type of damage, you can determine the necessary replacement part(s). You’ll need to find a replacement screen that is compatible with your exact laptop make and model. Replacement screens come in various forms:

  • Complete display assembly (easy drop-in replacement)
  • Just the LCD panel
  • Separate bezel assembly

For cracks or breaks in the actual display, a full replacement display assembly is usually best and easiest to install. The assembly will come with the LCD panel, bezels, cables, and backlight/inverter already put together and tested.

If you just have minor bezel damage or video cable issues, you may be able to replace those individual parts instead of the entire display.

Gather Tools and Supplies

Repairing a laptop screen requires some special tools. Having the right equipment makes the repair process much smoother. Before disassembling your laptop, make sure you have the following:

Essential Tools

Follow these steps when selecting the correct replacement part:

  2. Note the size of your display – the inch measurement diagonally (e.g 15.6-inch)
  3. Find out if you have a touchscreen display or not
  4. Note the resolution or pixel dimensions (e.g. 1920 x 1080)
  5. Purchase a replacement screen with identical specs from a reputable parts supplier

  2. Carefully remove any screws from the back panel and set them aside in an organized way.
  3. Starting prying up the plastic edges around the perimeter of the display side. Apply steady pressure with your plastic tools to release the snapped on clips from the frame.

  2. Line up any brackets or mounting points and lower it directly into the open frame where the original screen was located.
  3. Thread any display cables through the openings and firmly plug them into their respective ports on the motherboard. You may need to refer back to disassembly photos to reconnect everything properly.
  4. Reattach any small mounting screws or adhesive strips to hold the screen firmly in position inside the frame.
  5. Finally, snap the plastic rear cover back into place starting from the hinges and applying steady pressure to reseat the perimeter clips. Replace all screws.
