problems. Printed circuit boards requiring troubleshooting should be returned to the
factory.
8

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 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 items in section (A), power supply
voltage and fuses.
(e) 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.
(f) 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.
(g) 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.
9

(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 c. Otherwise contact customer service with results or see Advanced
Troubleshooting, section C.
(c) If the voltage from step a 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 c. 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 cabled 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 f.
(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.
10

(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 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 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 c.
(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 f.
(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 who has experience working on electronic equipment. If
possible, consult with customer service before proceeding.
11

(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
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 h.
(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.
12

(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
damage to the scoreboard or console could result from static or other outside
sources.
(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.
