Step-by-Step Tutorial: Replacing a Lenovo Legion Y740-17IRH Laptop Screen

In this tutorial, I will guide you through the process of replacing a cracked screen on a Lenovo Legion Y740-17IRH gaming laptop.

Tools Needed:

• Pry tool
• Screwdriver (suitable for your laptop’s screws)
• Replacement screen
• Safety goggles

Steps:

1. Turn Off the Laptop:
   • Ensure the laptop is completely turned off. Press and hold the power button if necessary.
   • Check that indicators like the caps lock light are off, confirming the laptop is indeed shut down.
2. Prepare the Work Area:
   • Lay the laptop flat with the screen fully open.
   • Put on safety goggles to protect your eyes from any potential glass shards.
3. Removing the Bezel:
   • Insert the pry tool between the bezel and the screen. Gently pry around the edges to loosen the bezel.
   • The bezel is held in place with clips and possibly double-sided tape, so proceed with care to avoid breaking it.
   • Once loose, gently remove the bezel and set it aside.
4. Removing the Damaged Screen:
   • Locate and remove the screws holding the screen in place. There are usually four screws, two on the top and two on the bottom of the screen.
   • Carefully lift the screen and gently tilt it forward to expose the cable connector on the back.
   • Gently detach the connector. This may be secured with tape, so carefully peel that away first.
   • Remove the damaged screen and set it aside.
5. Installing the New Screen:
   • Take the new screen and align it in the same position as the old one.
   • Carefully connect the cable to the new screen. Ensure it is securely fastened.
   • Place the new screen back into the frame and secure it with the screws you previously removed.
6. Reattaching the Bezel:
   • Carefully align the bezel back into its original position.
   • Press around the edges to snap it back into place. The clips should click, indicating they are secure.
   • If there was double-sided tape, ensure it adheres well to keep the bezel in place.
7. Testing:
   • Once everything is reassembled, turn on the laptop to test the new screen.
   • Check for any display issues and ensure the screen is functioning properly.

Conclusion:

Replacing a laptop screen can seem daunting, but with the right tools and careful handling, it’s a manageable task. If you feel uncomfortable at any point, consider seeking professional assistance. Always ensure you purchase the correct replacement screen for your specific laptop model.
