22 Scoreboard Troubleshooting
Replacing a Driver
If the driver status indicators do not appear to be working correctly, it may be necessary to
replace the driver.
1. Open the digit panel or scoreboard face panel as described in Section
‎
5.2 .
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 wing nuts securing the driver to the driver tray.
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 access panel, then power up and test the scoreboard to see if
changing the driver has resolved the problem.
Setting the Driver Address
Since the same LED drivers can be used for many
scoreboard models, each driver must be set to
receive the correct signal input, or address, for the
model being used. This address is set with jumper
wires in a 12-pin plug which mates with jack J19 on
the driver (
Figure 17 ).
It may be possible to reuse the same address plug
from the driver that was replaced. If not, refer to
Drawing A-1054354 in Appendix A for a listing of
the wire/pin connections for up to 12 courts and
Team Score module, including TNMCs.
5.5 Segmentation and Digit
Designation
In each digit, certain LEDs always go on and off together. These groupings of LEDs are called
segments
. Drawing A-38532 in Appendix A details which connector pin is wired to each
digit segment and the wiring color code used throughout the display.
The component location
drawings in Appendix A specify the driver connectors controlling
the digits. Numbers shown in hexagons in the upper half of each digit indicate which
connector is wired to that digit.
