8.2 Instructions for Replacing Parts
Module Replacement
Tool Required: 1 /
8
" Hex Wrench
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 Section 6.2
to 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 at both top and bottom by
turning the hex wrench a quarter turn clockwise.
