Scoreboard Troubleshooting 23
Problem Possible Cause Solution/Items to Check
Scoreboard works, but some
LEDs do not light or they
blink
Bad connection
Verify the Mate-N-Lok connector on
the back of the digit circuit board is
secure (see Section 5.2 ).
Verify power/signal interconnect(s)
between scoreboard sections
properly connected
(see Section 4.5 )
Bad digit or driver
Swap the digit/driver with one known
to work correctly to verify the
problem. Replace if necessary (see
Sections 5.4 for digits or
Section 5.5 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 could
be transmitting to the scoreboard.
An example would be football and
baseball scoreboards that are within
1500 feet of each other
(see Section 5.6 ).
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 Access
All internal electronic components are
reached by opening an access door or a
digit panel on the display.
Digit panels are held in place on the
scoreboard face by an offset flange across
the top and by screws at the bottom, as
shown in
Figure 15 .
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.
