Scoreboard Troubleshooting
Note: While it is necessary to have the scoreboard powered on to check the LED
indicators, always disconnect scoreboard power before servicing.
To replace a driver:
1. Open the digit panel as described in Section 4.2.
2. Disconnect all 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 the driver.
3. Remove the screws or nuts securing the driver to the inside of the enclosure.
4. Carefully lift the driver from the display and place it on a clean, flat surface.
5. Position a new driver over the screws and tighten the nuts.
6. Reconnect all power/signal connectors.
Note: The connectors are keyed and will attach in one way only. Do not attempt to
force the connections.
7. Ensure the driver is set to the correct address (refer to Setting the Driver Address).
8. Close and secure the face panel, then power up and test the scoreboard to see if
changing the driver has resolved the problem.
