Modules and Drivers
A module consists of louvers, an LED board and a driver board mounted to the back.
Refer to Section 4.5 to open a display via the modules and access the LED board and
driver boards.
An LED board is a circuit board with 32 LED pixel clusters mounted directly on it.
Each LED board is removable from the module. To remove an LED board from the
module:

2. Disconnect the power and signal connector from the driver on the LED
board you wish to replace.
3. Remove the four nuts holding the LED board to the louver assembly.
4. Remove the 5/16” nut that holds the driver to the LED board, and gently pry
the driver from the LED board. (A ¼” hex screw can be removed from the
front of the LED board to remove the driver and the stand-off.
5. Reverse the above procedure to install a new pixel board.
Figure 38: Driver Board
