Scoreboard Troubleshooting 21
6.4 LED Driver
The LED driver performs the task of switching digits on and off within the scoreboard.
LED drivers are located inside of a driver enclosure. Refer to Drawing A-159887 in Appendix
A to view the location and components of the driver enclosure.
When troubleshooting driver problems, several LEDs provide diagnostic information.
The number of LEDs and their function depends on the driver type.
Note: While it is necessary to have the scoreboard powered on to check the LED
indicators, always disconnect scoreboard power before servicing.

Replacing a Driver
1. Open the back panel as described in Section 6.2.
2. Remove the metal cover of the driver enclosure to expose the driver components.
3. Disconnect all connectors from the driver by squeezing together the locking tabs and
pulling the connectors free. It may be helpful to label the cables to know which cable
goes to which connector when reattaching the driver.
4. Remove the screws or nuts securing the driver to the inside of the enclosure.
5. Carefully lift the driver from the display and place it on a clean, flat surface.
6. Position a new driver over the screws and tighten the nuts.
7. Reconnect all power/signal connectors. Note that the connectors are keyed and will
attach in one way only. Do not attempt to force the connections.
8. Ensure the driver is set to the correct address (refer to Setting the Driver Address).
9. Close and secure the back panel, then power up and test the scoreboard to see if
changing the driver has resolved the problem.
