Daktronics SW-2101 Aquatics/Track LED Scoreboard - Manual (Page 23)

Scoreboard Troubleshooting 17
Problem Possible Cause Solution/Items to Check
Scoreboard works, but some
digits do not light
Bad digit or driver (see solution on previous page)
Incorrect sport mode (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.
4.2 Component Locations & Access
All internal electronic components and digits are reached by
opening a digit panel on the front of the display.
Component location varies with each scoreboard model, but
drivers and power and signal components are typically
mounted inside the scoreboard behind a digit panel. Look for
labels similar to those shown in Figure 8 to access primary scoreboard components.
For model-specific component layouts and access locations, refer to the Electrical
Specification drawings listed in Appendix B.
To open a digit panel:
1. Hold the digit panel in place by putting hand pressure on it, and remove the
holding screws.
2. Carefully lift the panel away from the scoreboard, sliding it out and down.
Note: If the panel is not held in place when the screws are removed, it could drop
and possibly damage LEDs or the digit harness.
When closing a digit or access panel, make sure all screws/latches are holding it firmly in
place to prevent moisture and debris from entering the scoreboard.
4.3 Replacing Digits
Digits consist of a circuit board with embedded LEDs mounted to a black polycarbonate tray
and encased in protective gel as shown in Figure 9. One or more digits may be secured to a
single face panel. Do not attempt to remove individual LEDs; in the case of a malfunctioning
LED or digit segment, replace the entire digit.
