Add Note Edit Step 1 — Rear Display Bezel  ¶ 

  • Remove the single Phillips screw near the lower left and right corners of the display.

  • Removing these two screws may be difficult. It is helpful to open the display as much as possible for clearance to use a screwdriver. Also, a combination of #00 Phillips and small flathead screwdrivers along with a pair of tweezers may aid in removal.
