The cable pictured below is adhered down, so using the Plastic Pry Tool, come from behind the Shield Plate, following the cable down to the adhered section, gently prying underneath it to free the cable from it's adhesive. (Below is an example of prying the cable from behind the Shield Plate).
Once all screws are removed and the cable is free from the adhesive, the Shield Plate is able to be removed and transferred over to the new replacement Screen
Re-apply the three screws either side and one bottom screw to secure the Shield Plate
