Replacing a Driver
1. Access the internal components as described in Section ‎ 7.5 .
2. Disconnect all power and signal connectors from the driver by squeezing together the
locking tabs and pulling the connectors free.
Note: It may be helpful to label the cables to know which cable goes to which
connector when reattaching a driver.
3. Remove the four screws securing the driver to the module. This will be the right-most
module, when viewing the display from the front.
4. Position a new driver over the standoffs on the module and tighten the screws.
5. Reconnect all power/signal connectors.
6. Power up and test the scoreboard/display to see if the problem has been resolved.
