How to Replace the Screen Adhesive on Your Switch Lite

Apply high concentration (90% or greater) isopropyl alcohol to the old screen adhesive on the frame.

Wait one minute to allow the alcohol to penetrate the adhesive.

Use the flat end of a spudger to scrape all the old adhesive from the frame.

Use a microfiber cloth to clean the frame.

Measure and cut four strips of 2 mm‑wide Tesa tape for the back of the screen:

Two strips for the long edges

Two strips for the short edges

Apply the adhesive strips sticky side down to the back of the screen, making sure the tape goes under the screen and digitizer cables.

Use tweezers to remove the liners from the adhesive strips.

Orient the screen before adhering it to the frame:

The right edge of the screen has two wide cables that line up with the action buttons.

The left edge of the screen has one small cable that lines up with the directional pad.

Lay the right edge of the screen on the frame at a downward angle, making sure its cables go under the frame.

Lay the left edge of the screen onto the frame, making sure the small cable goes under the frame.

Press down firmly around the perimeter of the screen to adhere it to the frame.
