Insert the tip of an opening pick under the center of the left edge of the screen at a steep angle.

Push down the opening pick so that it is level with the screen.

Leave the opening pick in the center of the left edge of the screen to prevent the adhesive from re-sealing.

At this point, the perimeter of the screen should be separated from the frame. If there is still resistance around the edges of the screen, use an opening pick to cut the adhesive again.
