Figure 5. Accessing the LCD
Replacing the LCD
The LCD assembly consists of four pieces as shown in Figure 5:
• Translucent light-dispersing back panel
• Flexible elastomeric conducting strip
• Plastic bezel for housing the assembly's components
• Glass LCD display
With the LCD assembly removed from the PCA, use the following procedure to replace
the LCD:
1. Lift the translucent light dispersing back panel off of the plastic bezel.
2. Remove the pink and black elastomeric strip from its slot in the bezel.
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.
