Removal
1. Before starting this procedure, fill out a Service Data Sheet if this has not already been done. A
copy is located at the back of this manual.
2. Power the unit off and disconnect power from the unit.
3. Remove the four screws from the sides of chassis near the front.
4. Unplug the 34-pin ribbon cable from the back of the display controller board.
Replacement
1. Plug the 34-pin ribbon cable in the back of the display unit. This header on the display controller
board is not labeled. The red edge of ribbon cable should be on the side closest to the center of
unit. The ribbon cable should go up from the header and loop back over to P202 on the NAV
board. This keeps it up out of the way of the card slot. The red edge of the ribbon cable should go
to P202 pin 1. See Figure 8-3.
2. Position the bezel assembly (see the Parts Required section above for correct part number) in
place on the front of the chassis and replace the four screws (224-0414) on the sides of chassis
near the front.
Torque screws to 5.0 lb.-in.
3. Flatten the cable so it does not touch the switch assembly.
4. Test the unit to verify proper operation (see Return to Service procedures).
5. Using the Service Data Sheet, reenter the customer configuration.
