20 Maintenance
6.2 Internal Display Access
At times, the display may need to be opened for maintenance, or for troubleshooting. Follow
this procedure safely and properly to access the interior of the display.
1. Disconnect power to the display.
2. Locate the latch access fasteners on the
module. Refer to Figure 24. Locate one
centered near the top, and the other
centered near the bottom.
3. With a 1 /
8
" hex wrench, turn the latch
access fasteners a quarter turn counter-
clockwise.
4. Gently pull the module far enough forward
to reach behind the module.
Note: Do not allow the module to hang by
its power and signal cables.
5. Unplug the power cables, squeeze the tabs
on the sides of the plug head, and pull out.
6. Disconnect the two ribbon cables from the
module by spreading the side tabs, and
then lifting the cable head from the jack.
Note the cable connection locations to ensure proper reconnection.
7. When ready to reinstall the module, reconnect the cables to the module. Tightly push
the tabs against the cable head. Carefully push the ribbon wires back into the cabinet
so they are clear of the module edges.
8. Place the module in its proper location.
9. Check that the weather stripping is in place. To prevent water from entering the
display, the weather stripping on the back edge of the module must be in good
condition.
10. Latch the module at both the top and bottom locations by turning the hex wrench
clockwise a quarter turn. Fully engage the module latches to create a watertight seal
around the edge of the module.
