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.
Each module may 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 38).
3. Disconnect the two ribbon cables from the module,
noting their connection to the back. (Figure 39). Release
ribbon cables by spreading the tabs on the sides and
then lifting the cable head from the jack.
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 using the hex wrench.
Notes:
• 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.
• 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.
