Replacing a Digit Segment
When a digit malfunctions, in most cases it is necessary to replace the entire digit
circuit board. Some larger digits (36", 48", 60"), however, are constructed in
segments, as shown in Figure 9, 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. Do not attempt to remove individual
LEDs.
To remove a digit segment, follow these steps:
Display Maintenance 3-3
and Troubleshooting
1. Open the digit panel as described
above.
2. Disconnect the 2-pin or 4-pin
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 replace and tighten the nuts.

5. Reconnect the power/signal connector.
Note: This is a keyed connector B it will attach in one way only. Do not
attempt to force the connection!
6. Close and secure the digit panel and test the display.
