Daktronics BB-2101 Tuff Sport Basketball LED Scoreboard - Manual (Page 27)

Scoreboard Troubleshooting 21
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 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.
5.2 Component Location & Access
All Tuff Sport indoor basketball displays are front-access scoreboards, meaning that internal
electronic components and digits are reached by opening a face panel, an access door, or a
digit panel on the front of the display.
Digit panels are typically held in place on the scoreboard face by two screws. To remove a
digit, simply unfasten the screws and carefully lift it from the cabinet. The power/signal plug
can then be removed from the connector on the back of the digit to completely free the digit
and access internal components.
Remove non-digit access panels by unfastening the top, side or bottom screws holding it in
place. Some panels are hinged and swing open when the screws are removed or loosened.
Component location varies with each scoreboard model,
but drivers and power and signal components are
typically mounted inside the scoreboard behind a digit
panel. To locate the driver(s), look for a warning label
similar to that shown in Figure 13.
Refer to the electrical and signal specification drawings in
Appendix B for model-specific component layouts and
access locations.
5.3 Replacing Digits
LEDs are embedded in a circuit board that is mounted to
the back of the digit panel. Do not attempt to remove
individual LEDs. In the case of a malfunctioning LED or
digit segment, replace the entire digit circuit board.
The process of replacing digits varies by whether it is a
PanaView
® digit or UniView ® digit (Figure 14).
