8.2 Instructions for Replacing Parts
Module Replacement
If LEDs have failed, do not attempt to replace individual LEDs.
Return a failed module to Daktronics for replacement and/or repair.
Figure 49: Module, Front/Back
Each module can be removed separately without
moving other components of the display.
1. Turn off power to the display.
2. Follow the instructions in Section 6.1 to release
the module from the display cabinet (Figure
50).
3.
Disconnect the two ribbon cables from the
module, noting how they are connected to the
back. Release ribbon cables by spreading the
tabs on the sides and then lifting the cable head
from the jack (Figure 49).
4.
Unplug the power cable by squeezing the tabs
on the sides of the plug head and pulling out.
5.
Connect all three cables to the new module,
making sure that the ribbon cable tabs are
tightly pushed against the cable head. Carefully
push the ribbon wires back into the cabinet so
they are clear of the module edges.
6. Place the module into its proper location,
checking that the weather stripping is in place.
Latch the module tightly both top and bottom
by turning the hex wrench a quarter turn
clockwise.
Note:
• The weather-stripping on the back edge of the module must be in good condition and
returned to its proper position if it is to prevent water from seeping into the display.
Figure 50: Removing a Module
• The module latches must be fully engaged to
create a watertight seal around the edge of the
module. The module should be firmly seated
against the display when the latches are fully
engaged.
