LED Module Replacement
If any LED modules fail, the recommended procedure is to replace the failed module
or send it to Daktronics or a Daktronics Sales and Service office for repair.
To remove an individual module:
1. Disconnect Power to the display.
2. Push the clips outward and gently pull the 40-pin ribbon cables from
the failed module as shown in Figure 31 .
3. Open the display and access the display interior as previously
described.
4. Press the tabs on either side of the four-pin power connector to release
it and shown in Figure 30 .
5. Each module is held in place by #6 screws. Using a 3/16” nutdriver,
remove the module screws from the rear of the panel.
6. Gently pull the failed module from the panel. Reverse the previous
steps to attach a new module.

Power to the LED modules is provided by
a small 5V power supply. Each power
supply can support up to three (3)
modules. They are located on the back
sheet of the display.
Each power supply is secured to a power
supply plate by two (2) 3x10 metric
screws. The plate is secured to the back
sheet by two (2) #6 hex head screws as
