Problem Possible Cause Solution/Items to Check
Scoreboard works, but some
digits do not light
Bad digit or driver (see solution above)
Incorrect sport code (see solution on previous page)
Incorrect driver address (see solution on previous page)
Wrong console controlling
scoreboard
Another console’s radio signal could
be transmitting to the scoreboard.
Radio interference
There may be other radio
transmissions in the area that
overpower the console. If it is not
possible to disable the interfering
device, It may be necessary to run a
wired signal connection instead.
All Daktronics LED squash scoreboards are front-access scoreboards, meaning that internal
electronic components and digits are reached by opening a face panel on the front of the
display.
To remove a face panel, simply unfasten the screws holding it in place and carefully lift it
from the cabinet. The power/signal plugs can then be removed from the connectors on the
back of the digits to completely free the digits and access internal components.
Refer to the electrical and signal specifications
Drawing A-133613 in Appendix A for exact
component layouts and access locations.
LEDs are embedded in a circuit board that is mounted to the back of the face panel. Do not
attempt to remove individual LEDs. In the case of a malfunctioning LED or digit segment,
replace the entire digit circuit board.
To replace a digit circuit board (
Figure 7 ):
1. Open the face panel as described in Section 5.2 .
2. Disconnect the power/signal connector 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 stud inserts.
4. Position a new digit over the studs (making sure the small plastic spacers are still in
place) and tighten the nuts.
5. 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.
