4. MAINTENANCE AND TROUBLESHOOTING
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.
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
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.
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) Scoreboard digits don't light, but the console works
(a) With the main power switch "off";remove the cover over the controller
assembly.
(b) Check all connections.
(c) Turn the main power on.
(d) If the scoreboard still doesn't light, check the transformer voltage going to the
receiver PCB (printed circuit board) assembly (blue wires) using a voltmeter
set on the
12 VAC or higher scale.
If the voltage is less than
8 VAC contact the customer service department.
If the voltage is between
8-12 VAC see the replacement parts list for a
receiver PCB assembly, and contact the customer service department.
(C) 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 0 VAC see the controller parts list for a transformer
assembly.
If the voltage is less than
8 VAC consult the controller wiring diagram for
instructions on long cable compensation.
If the voltage is between
8 VAC and 12 VAC contact the customer service
department.
(D) The scoreboard digits light, the console works, but there is no control of the
scoreboard.
(a) Check the voltage between the black and red wires in the junction box with a
voltmeter set on the 3 VDC or higher scale. The voltage should read
somewhere between 2-3 VDC when the console is working properly.
(b) If the voltage is
0 VDC contact the customer service department for
assistance.
(c) If the voltage is correct, (2-3 VDC) check that this reading also appears at the
scoreboard.
(d) If the correct voltage also appears at the scoreboard, see the replacement parts
list for a receiver PCB assembly.
(E) The scoreboard works, but some lights stay on all the time
(a) With the main power "OFF", switch the plug from the bad digit with the plug
for a known good digit.
EXAMPLE: Plug "C" into "D" and "DMinto "C" locations.
(b) Turn the power back on. If the same lamps remain lit all the time, the
problem is a shorted lamp socket. If the lamps on a different digit now stay lit
all the time, the problem is on the driver PCB assembly. See the replacement
parts list for the proper replacement part.
(F) The scoreboard works, but some lights do not come on.
(a) Check for burned out lamps.
(b) Check for a broken wire or bad connection on the
12 pin connector.
(c) See the replacement parts list for the proper replacement driver board.
