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
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
(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.

9
(C) 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 from the transceiver on the controller
Assembly 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, or 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 "D" into "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.
IMPORTANT !!!
In this scoreboard the 120 volt line is on the lamp socket all the time, and the common
is switched to turn the lamps on and off. For this reason, to avoid damage to the
equipment or personal injury, it is important to turn the main power off when changing
the lamps.
(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.
