5.5 Instructions for Replacing Parts
Replacing a Digit
On displays with 10”, 13”, and 18”digits, a
digit circuit board is mounted to the back of
the digit panel. Do not attempt to remove
individual LEDs, but rather replace the
entire digit panel. Refer to Figure 15. To
remove a display digit, follow these steps:
1. Open the digit panel as described
in Section 4.1.
2. Disconnect the power connector
from the back of the digit. Release
the connector by squeezing
together the locking tabs and pull
the connector free.
3. Digits are secured to the inside of
the panel with fixed machine
screws, and push nuts. Remove the
nuts and lift the digit off the
standoff screws. (Push nuts can be removed in several ways, but Daktronics
recommends using a 9 /
32
" nut driver.)
4. Position a new digit over the screws and tighten the nuts.
5. Reconnect the power connector. Note: This is a keyed
connector - 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.
Replacing a Digit Segment
The larger digits (24") are constructed in segments, as shown
in Figure 16. In this case, make repairs by removing only the
defective segment. Do not attempt to remove individual
LEDs. To remove a digit segment, follow these steps:
1. Open the digit panel as described in Section 4.1.
2. Disconnect the two-pin power connector from the
back of the individual segment. Release the connector
by squeezing together the locking tabs and pull the
connector free.
