Possible Solutions:
a. If there is no display in the console’s LCD, first check that electrical
power being supplied to the scoreboard is on. If the power is on, confirm
that the data cable jack from the scoreboard to the console is plugged into
the right side of your console labeled “DATA CABLE” and not into the left
side labeled “MICROPHONE”.
b. The data cable may be disconnected or broken. If you have a second
data cable, test the console by swapping the second data cable.
c. If the LCD display is all or partially black, this could be occurring if the
console display is exposed to high temperatures. Shield the console from
direct sunlight or high heat (over 100 degrees F). The LCD display will
return to normal after it cools.
d. If the LCD displays black with multi-colored patterns, the LCD is
broken internally. Return the console to the factory for service.
Possible Solutions:
a. If the console display shows incorrect data, random data or incomplete
segments, the console may be “locked up”. Remove electrical power to the
scoreboard for ten seconds and then reapply power. (See page 7-1, under
“What To Do If ‘Nothing’ Works”). If this does not solve the problem,
press the DUAL SCBD SYNC key on the console several times. If this does
not solve the problem, the problem may be elsewhere; check the data
cable, digit cable and connection on the control board. Refer to “What To
Do If ‘Nothing’ Works” on page 7-1.
