Scoreboard Troubleshooting 5
Problem Possible Cause Solution/Items to Check
Bad digit or driver
Exchange the digit/driver with a
working one of the same part # to
verify the problem. Replace if
necessary (see Section 2.3 for
digits or Section 2.4 for drivers).
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 may
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.
Scoreboard works, but a
certain section of digits do
not light
Bad multi-section connection
Verify power/signal interconnects
between scoreboard sections are
properly connected. Refer to the
appropriate schematic drawings.
Bad transformer
Exchange the transformer with a
working one of the same part # to
verify the problem. Replace if
necessary.
2.2 Component Locations & Access
All indoor scoreboards are front-access, meaning that internal electronic components and
digits are reached by opening a digit panel on the front of the display.
Digit panels are typically held in place on the scoreboard face by 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.
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 4.
For model-specific component layouts and access
locations, refer to the electrical and signal or component
location drawings attached to the product specifications
sheets listed in Appendix A.
