4.1 Introduction
This section gives maintenance and troubleshooting information. Included are
troubleshooting guides for typical scoreboard malfunctions. If the cause of a problem
cannot be determined, please contact the customer service department.
WARNING !!!
120 VAC wires are exposed whenever the cover over the power supply assembly is
removed from the scoreboard. Use extreme caution during troubleshooting or repair.
To avoid possible damage to equipment or personal injury, always turn off the main
power before removing the cover or replacing assemblies.
6

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.
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) Check to see that the Green LED on the power supply is lit.
(e) Check for 12 VDC at the power supply terminal.
(f) 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 red wire
and the black wire in the junction box, using a voltmeter set on the 12 VDC
or higher scale.
If the voltage is 10 VDC or greater contact the customer service
department.
If the voltage is 0 VDC, 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 (red and black wires).
If the voltage is less than 10 VDC consult the wiring instructions for long cable
compensation (modify for AC adaptor).
7

If the voltage is 10 VDC 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 D1 on the receiver board is flashing rapidly call the customer service
department.
If LED D1 on the receiver board is not flashing, plug the control console
directly into the top of the scoreboard.
If LED D1 on the receiver board flashes now check the junction box and data
cable for continuity. (green and white wires)
If LED D1 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.
(e) Check LED D4 on the receiver board. It should be medium brightness. Change
the Dim level on the control console. D4 brightness should change.
(f) Check if LED D5 on the receiver board is on.
If D5 is on, check if D2 and D6 are flashing and call customer service
department. The flash will be very fast. The LED's may appear to be on at
half brightness.
8

If D5 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) Find the first digit in the shift order that is not working.
(b) Check for 12 VDC at the digit.
(c) Reseat the data in and data out cable connectors.
(d) Swap the driver board with a driver further down the shift order.
(e) If the digit still doesn't work call the customer service department.
