24 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 18 ).
It may be possible to reuse the same address plug
from the driver that was replaced. If not, first refer
to the specifications table in
Section 2 to find the
correct driver address(es) for a particular scoreboard
model. Then refer to
Drawing A-1054354 in
Appendix D for a listing of the wire/pin
connections for up to 12 courts, including TNMCs.
Multiple Drivers
Scoreboards that require multiple drivers operate using a master/slave driver configuration.
Master and slave drivers function identically, but slave units lack the power/signal
termination blocks. The drivers have been designed to simply plug into one another, and this
is done at the factory, so no additional on-site connection is necessary.
If it appears as though only a certain group of digits on the scoreboard is not functioning,
there may be a problem with the slave driver(s) or the power/signal connection from the
other driver(s).
