Digit Panel (rear view)
The digit breakout board, the central signal/power
termination for the segments, is mounted to the back of the
digit panel. If the entire digit is malfunctioning, replace
the breakout board. Refer to Drawing A-155644.
To remove a digit breakout board, follow these steps:
1. Open the digit panel as described in the previous
section.
2. Disconnect all of the 2-pin and 9-pin power/signal
connectors from the back of the breakout board.
Release the connectors by squeezing together the
locking tabs as you pull the connector free. Refer
to Figure 7.

the panel with standoff bolts, spacers, and nuts.
Remove the #8 nuts and lift the breakout board off
the standoff bolts.
4. Position a new breakout board over the bolts and tighten the nuts.
5. Reconnect the power/signal connectors. K Note: These are keyed connectors B they
will attach in one way only. Do not attempt to force the connection!
6. Close and secure the digit panel and test the scoreboard.
Replacing a Driver
Drivers are typically mounted inside the scoreboard and immediately behind a digit, but location
and mounting varies. Refer to the Component Locations drawings for the location of your
scoreboard driver.
Each driver is enclosed with a power supply and signal terminal block. Before a failed driver
can be reached, the enclosure must be accessed. Follow these steps:
1. Open the digit panel or scoreboard face panel as described in Section 8.2.
2. Remove the cover from the driver enclosure.
3. Disconnect all connectors from the driver. Release each connector by squeezing
together the locking tabs as you pull the connector free. K Note: When reconnecting,
remember that these are keyed connectors and will attach in one way only. Do not
attempt to force the connections.
4. Remove the hardware securing the driver to the inside of the enclosure.
5. Carefully lift the driver from the display and place it on a clean, flat surface.
6. Follow steps 1 through 5 in reverse order to attach a new driver.
