4.0 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. Read through the appropriate troubleshooting section before
beginning a repair. Refer to the diagrams in chapter 6 as an aid 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 and providing power to the scoreboard.
(b) Check to see that the green Led is lit on each power supply.
(c) Check for 24 VDC at the power supply terminals.
(d) Check the 110 VAC power connections and voltages at the scoreboard.
(e) Replace any defective or blown fuses.
(f) Check for 12 to 16 VDC on the red and black wires at the data cable terminal block.
(g) Contact the Customer Service Department.
(B) Scoreboard digits
(a) Check all connections.
(b) Turn the main power "on".
(c) If the scoreboard still doesn't light, check the items in section (A), power supply
voltage and fuses.
(d) Check if LED D1 on the receiver board is lit. If not, check that the receiver board is
plugged into the power supply board, then contact the customer service department.
8

(e) Check to see that the LED on the first driver board (closest to receiver) is flashing. If not,
check the data cable connections (orange and grey wires) from the receiver to the
drivers, and check to be sure that the power connection to the driver board is OK.
(f) If the driver board LED is still not flashing, connect a different driver board to the
receiver (first in line). If the LED is now flashing, the first driver board should be
replaced. Otherwise the problem is on the receiver board.
(C) The scoreboard digits light but the console doesn't work.
(a) For a cable connected system, check for 12 to 16 VDC between the red and black wires
In the junction box. For wireless consoles, check the output of the wall transformer by
unplugging it from the console, putting the + meter lead into the center cavity of the power
plug and touching the meter lead to the metal shell. The reading should be at least 10 VDC.
(b) If the voltage is 10 V or more, turn on and code in the console, even though it may not
appear to be working. Listen for beep sounds when pressing the keys, and see if the
scoreboard responds at all. If the scoreboard is radio controlled, go to section D, step 3.
Otherwise contact customer service with results or see Advanced Troubleshooting, in
section C.
(c) If the voltage from step 1 is zero, measure the voltage on the red and black wires at the
terminal block inside the scoreboard. If the voltage is still zero, go to section A, step 3.
Otherwise check the cable to the junction box for continuity.
(d) Refer to advanced troubleshooting, section B to connect the console directly to the
receiver board.
(D) The scoreboard digits light, the console works, but there is no control of the scoreboard.
(a) If the scoreboard is a hardwired system, check for 1 to 4 volts AC on the green and
white wires at the junction box (console on and coded in). Then go to step 6.
(b) With wireless consoles, be sure that the battery (if so equipped) is fully charged, or
better still, use the wall transformer to power the console.
(c) Check the LED on the radio adapter board inside the scoreboard. If it is lit, turn the
console off. This LED should go out about 5 seconds later. Turning the console on
again should relight the LED.
(d) Bring the console within 10 to 25 feet of the scoreboard and test again. If the radio
adapter LED now works, check and tighten antenna connections as necessary, both in the
scoreboard and in the console. CAUTION: the antenna connection at the radio can be
easily broken. Push or pull the connector STRAIGHT on or off!
(e) Check to see if D1 is lit. If not, check that the receiver board is plugged into the
power supply board, then contact the customer service department.
(f) With the console turned on and coded in, check to see that LED D2 on the receiver board
is flashing. If not, refer to Advanced Troubleshooting for instructions on connecting the
console directly to the scoreboard or contact customer service.
(g) Starting with the driver board closest to the receiver, check to see that the LED on each
driver board is flashing. If not, check the data cable connections (orange and grey wires)
from the receiver to the drivers, and check to be sure that the power connection to the
driver board is OK.
(E) The scoreboard works, but some lights stay on all the time
(a) With the main power "OFF", disconnect (and tag) the suspect digit from the driver board.
Plug a known good digit into that position on the driver card. Do Not Plug the Suspect
9

Digit into any other location!
(b) Turn the power back on. If the good digit shows the same problem as the original digit,
there is a problem on the driver PCB assembly. See the original digit, replacement parts
list for the proper replacement part or refer to Advanced troubleshooting, section A to
swap another driver board into that position. There may also be a problem with the digit or
its cabling, continue with step 3.
(c) Check the digit and cable assembly for shorts to the scoreboard frame and to the + and -
power leads.
(d) Plug the suspected bad digit into another output position. USE the SAME driver board
(A bad digit may be the cause of a driver board failure). If the same lights remain on,
replace the digit and driver board.
(F) The scoreboard works, but some lights do not come on.
(a) If only part of a digit works, e.g. a 0 looks like a U, go to step 6.
(b) If one or more of the digits are completely blank, check the LED on the corresponding
driver board.
(c) If the LED is blinking, check the power connection at the opposite end of the board for
24 VDC. If not, check the power and data cable connections on the driver board.
(d) Plug the blank digit into a known good driver board position. If it is still blank, check for
broken wires or bad connections in the digit cable. Replace the digit if the cabling is OK.
(e) If the digit now works, see the replacement parts list for the proper replacement driver
board or refer to Advanced troubleshooting, section A to swap another driver board
into that position.
(f) Disconnect the suspect digit and plug a known good digit into that driver location.
(g) If the good digit shows the same problem, see the replacement parts list for the proper
replacement driver board or refer to Advanced troubleshooting, section A to swap
another driver board into that position.
(h) If the good digit is working, check for a broken wire or bad connection on the 10 pin
connector.
(i) Contact customer service for the proper replacement digit.
4.5 Advanced Troubleshooting
In emergency situations (Tournament begins in an hour), the following steps may help to make
the scoreboard usable in a temporary fashion. These procedures are best performed by someone
that has experience working on electronic equipment. If possible, consult with customer service
before proceeding.
(A) All of the driver boards in a 7000 series scoreboard are interchangeable. However, each
board has an address programmed inside its microcontroller chip. The chip from the board
being replaced must be put into the new board for proper operation. Example: The scoring
driver of a football board has a problem. The Ball On/Yards To Go driver can be used in its
place. (Ball on and yards to go will not be usable until a new driver board is received from
the factory).
(a) Remove power from the scoreboard.
(b) Take the bad driver board out and set it aside. Put the replacement driver in position.
(c) Remove the processor chip from the new driver.
(d) Carefully take the processor chip out of the old driver board and install it in the
10

replacement board. Be sure the notched end of the chip is aligned correctly.
(e) Put the processor chip from the new board into the defective driver board so it doesn't
get lost.
(f) Reconnect power, data, and the display cables to the new driver board.
(B) Direct connection of consoles to scoreboards can be done to ensure that the
electronics is working properly. For radio controlled systems, skip to step 8.
(a) For a hardwired system, the cover of the junction box with the connector and wire
pigtail can be used. Open the junction box and disconnect the connector wires at the
terminal block.
(b) Take the cover plate/connector assembly up to the scoreboard. Attach the red and black
wires to the matching positions on the terminal block. Disconnect the red and black data
cable wires (that go to the junction box).
(c) Attach the green and white wires from the cover plate connector to the terminals on the
lightning protector board where the same colored wires connect to the receiver board.
(d) Disconnect the data cable (to the junction box) green and white wires from the lightning
protector board. Mark the board so that the wires can be put back on the correct terminals.
(e) Test the system. If it works, move the green and white wires from the cover plate
connector to the other two terminals on the lightning protect board.
(f) Test again. If the scoreboard works, there is a problem in the data cable somewhere
between the scoreboard and the junction box. If not, the lightning protector board
must be replaced.
(g) The data cable can be checked by re-installing the junction box cover plate and
connecting both green wires to one of the green wire terminals on the lightning board,
and doing the same with the white wires. While the scoreboard will operate with the
lightning protect board bypassed in this fashion, it should be fixed as soon as
possible, since the board also protects the electronics in the scoreboard from other
sources of potentially damaging interference.
(h) Radio controlled consoles may be connected directly to the scoreboard through the
12 pin radio connectors. Remove the radios and interface boards.
(i) Using 22 gauge solid wire, connect pin 10 of the console connector to pin 10 of the
scoreboard receiver board connector. Also connect pin 2 of the console connector to
pin 6 on the receiver board connector.
(j) Powering the console from the battery or wall cube, the system should operate.
This eliminates any radio related communication problems.
NOTE !: if it is necessary to operate the scoreboard this way, keep the 2 wires
as short as possible (10 ft. max), since there is no protection on these lines and
(C) Console problems
(a) Power is OK, but console does not turn on: check that the keypad connector is
plugged into the main board in the console.
(b) Console beeps, but has no display: check the ribbon cable between the main
console board and the display module.
(c) Erratic operation, abnormal display: check the socketed IC chips to be sure that
they are well seated.
