3.

 

Remove the old glass LCD display from the bezel. 

Note 

Make sure the new LCD display is clean (free of lint and finger prints) 

before placing it in position in the bezel. 

4.

 

Position the new glass LCD display in the bezel; the silver face should face the 

rear, and the stepped portion of the glass should be directly under the elastomeric 

slot on the bezel. 

5.

 

Drop the elastomeric strip into its slot on the bezel. 

6.

 

Position the translucent light-dispersing back panel over the silver side of the 

glass LCD display. Make sure the guide pins on the light dispersing back panel 

are facing up and that they are on the side opposite the elastomeric strip. 

7.

 

While holding the LCD assembly (face down) in one hand, position the PCA 

(fuse side up) over the bezel; match the guide holes in the PCA with the plastic 

guide pins on the bezel and the translucent light dispersing back panel. After the 

LCD assembly is in position, lock it in place by pressing (below the display) the 

bezel against the PCA; listen for the tab on the bezel to snap (lock) into position 

on the PCA. 

8.

 

Secure the PCA to the LCD assembly by installing the two screws that attach the 

PCA to the bezel. These screws also ensure contact between the glass LCD 

display, the elastomeric strip, and the PCA.
