cannot be determined, please contact the customer service department.

4.2 Test Equipment
A simple analog or digital voltmeter will be sufficient for all user repairable
problems. Printed circuit boards requiring troubleshooting should be returned to the
factory.
13
WARNING
120 VAC wires are exposed whenever the cover over the controller assembly is
removed from the scoreboard. Use extreme caution during troubleshooting or repair.
To avoid possible damage always remove power before removing the cover or
replacing assemblies.
4.3 Troubleshooting
Whenever possible, follow the troubleshooting guides prior to contacting the
customer service department. If a problem not described in the guides exists, contact
the customer service department immediately. Refer to the diagrams provided for
assistance in troubleshooting scoreboard malfunctions.
4.4 Troubleshooting Guides
(A) Scoreboard doesn't light and console doesn't work
(a) Check that the main power switch is turned on.
(b) Replace any defective or blown fuses.
(c) Check the power connections and voltages at the scoreboard.
(d) Contact the customer service department.
(B) The scoreboard digits light but the console doesn't work
(a) Check for continuity between the scoreboard and the junction box.
(b) If an open circuit is found, the problem is either the cable or a cable
connection.
(c) If the continuity test checks good, check the voltage between the green wire
and the white wire in the junction box, using a voltmeter set on the 12 VAC
or higher scale.
If the voltage is 10 VAC or greater contact the customer service
department.
If the voltage is 0 VAC, plug the control console directly into the top of the
scoreboard.

If the control works from the top of the scoreboard, recheck all cable
connections and check continuity again.
If the control still does not work, check the cable connections to the receiver
board (white and green wires).
If the voltage is less than 8 VAC consult the wiring instructions for long cable
compensation.
If the voltage is 8 VAC or higher contact the customer service department.
(C) The scoreboard digits light, the console works, but there is no control of the
scoreboard.
(a) With the main power switch "off"; remove the cover over the power
supply, and receiver.
(b) Check all connections.
(c) Turn the main power on.
(d) Turn the control console on and enter the code.
If LED D4 on the receiver board is flashing call the customer service
department.
If LED D4 on the receiver board is not flashing, plug the control console
directly into the top of the scoreboard.
If LED D4 on the receiver board flashes now check the junction box and data
cable for continuity.
If LED D4 on the receiver board still does not flash, call the customer service
department.
(D) Scoreboard digits don't light, but the console works
(a) With the main power switch "off"; remove the cover over the power
supply, and receiver.
(b) Check all connections.
(c) Turn the main power on.
(d) If the scoreboard still doesn't light, check the voltage between the
positive and negative terminal strips on the power supply for 12 VDC
with a voltmeter set on the 12 VDC or higher scale.
If the voltage is 12 VDC or greater, go to (e).
If the voltage is less than 12 VDC check the power supply input voltage for
120 VAC and contact the customer service department.
14

(e) Check if LED D7 on the receiver board is on.
If D7 is on, check if D5 and D6 are flashing and call customer service
department.
If D7 is not on, check that the receiver board is plugged into the power supply
and call the customer service department.
(E) The scoreboard works, but some digits do not change.
(a) Look at the digit wiring order table.
(b) Find the first digit in the wiring order that is not working.
