Scoreboard Troubleshooting

To replace a digit:

1. Open the digit panel as described

in Section 4.2.

2. Disconnect the power/signal plug

from the back of the digit by
squeezing together the locking tabs
and pulling the connector free.

3. Use a 9/32" nut driver to remove

the nuts securing the digits to the
inside of the panel, and then lift the
digit off the standoff studs.

4. Position a new digit over the studs.
5. Tighten the nuts.
6. Reconnect the power/signal

connector.

Note: This is a keyed connector and
it will attach in one way only. Do
not attempt to force the connection.


7. Close and secure the digit panel, then power up and test the scoreboard to see if

changing the digit has resolved the problem.

Segmentation & 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 B details which connector pin is wired to each digit
segment and the wiring color code used throughout the display.

The Electrical Specification drawings in Appendix B specify the driver connectors controlling
the digits. Numbers shown in the upper half of each digit indicate which connector is wired
to that digit.

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 10 to
view the typical components of a driver tray.
