The front display is adhered to the frame. It will be necessary to use a heatgun (on very low) or a good hairdryer to loosen the glue.

Apply the heat on the outside of the display. Do not stay to long in one are, move the heat continously around the outside of the display.

With the glue soft enough, use a small spatula, screwdriver or other small tool to separate the display from the frame.
