Module Replacement
If LEDs have failed, do not attempt to replace individual LEDs. Return a failed module to
Daktronics for replacement and/or repair.
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 the
Accessing the Internal Components (p.11)
release the module from the display cabinet.
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.
4.
Unplug the power cables 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 in order to prevent water from
entering the display.
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.
