An example would be football and
baseball scoreboards that are within
1500 feet of each other
(see Section 2.8).
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.

one known to work correctly to verify
the problem. Replace if necessary
(see Section 2.4).
Blown fuse(s) on power supply
circuit board (white digits only)
Replace the fuse(s) on the circuit
board (see Section 2.7).

Verify power/signal interconnect(s)
between scoreboard sections
properly connected. Refer to
appropriate scoreboard installation
manual and/or schematic drawings.
Bad power supply
Swap the power supply with one
known to work correctly to verify the
problem. Replace if necessary
(see Section 2.7).
Bad power supply circuit board
(white digits only)
Swap the circuit board with one
known to work correctly to verify the
