Scoreboard Troubleshooting 19
4.4 LED Drivers
In each scoreboard, one or more LED drivers perform the task of switching LEDs on and off.
LED drivers are located inside of an enclosure and mounted to a tray. Refer to Figure 20 to
view the typical components of a driver tray.
All scoreboards in this manual use 16-column drivers (Figure 20). Refer to the component
location drawings in Appendix A to determine the number of drivers for a particular
scoreboard model.
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.
