Once the screen is warm to touch, apply a suction handle to the bottom edge of the screen and as close to the edge as possible.

If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction cup to the screen.

Lift the screen with the suction handle to create a small gap between the screen and the frame.

Insert an opening pick into the gap between the frame and the screen.
