Work slowly around the edges to avoid cracking the bezel or damaging clips that hold it in place.

Once the bezel is removed, locate the screws securing the LCD panel to the metal brackets. These screws are often marked with small arrows or labeled. Remove them carefully, keeping track of each screw’s position for reassembly.

After unscrewing, gently tilt the screen forward. You will find a cable connected at the back of the panel, typically the video cable. Disconnect this cable by carefully pulling on the connector, not the wires, to avoid damage.

Choosing a Replacement Screen

Selecting the correct replacement screen is crucial for a successful repair. Laptop screens vary widely in size, resolution, connector type, and mounting style. Using an incompatible screen can result in display issues or incompatibility with the laptop’s hardware.

Key factors to consider when choosing a replacement screen include:

  • Screen Size: Measured diagonally in inches, commonly ranging from 11 to 17 inches.
  • Resolution: Ensure the replacement matches the original resolution (e.g., 1366×768, 1920×1080).
  • Connector Type and Position: Most modern laptops use a 30-pin or 40-pin LVDS or eDP connector; the connector’s position (top or bottom) must match.
  • Backlight Type: Typically LED; ensure compatibility.
  • Mounting Brackets: Check if the brackets on the replacement screen align with the laptop’s frame.

Consult the laptop’s model number and original screen part number, often found on a sticker on the back of the damaged screen, to find an exact match.
