Replacing a Digit Segment
Reference Drawing:
Digit Assemblies; Gen III & IV LED Digits .......................... Drawing B-177679
When a digit malfunctions, in most cases it is necessary to replace the entire digit
circuit board. Some larger digits (24", 30", 36"), however, are constructed in
segments, as shown in Figure 13, and it may be possible to make repairs by
removing only the defective segment.
As with smaller digits, the digit segment circuit boards are mounted to the back of
the digit panel.
Note: Do not attempt to remove individual LEDs.
Refer to Drawing B-177679. To remove a digit segment, follow these steps:
1. Open the digit panel as
described above in the
previous section.

2. Disconnect the 2-pin
power/signal connector
from the back of the
individual segment.
Release the connector by
squeezing together the
locking tabs as you pull
the connector free.
3. The individual segments
are secured to the inside of
the panel with fixed
machine screws, spacers,
and push nuts. Remove
the nuts and lift the
segment off the standoff
screws.
4. Position a new segment
over the screws and
tighten the nuts.
5. Reconnect the power/signal connector.
Note: This is a keyed connector and will attach in one way only. Do not
attempt to force the connection!
6. Close and secure the digit panel and test the scoreboard.
Note: Replace a malfunctioning colon, decimal, or indicator assembly in
the same manner.
