Troubleshooting Table
This section lists potential problems with the system, indicates possible causes, and
suggests corrective action. This list does not include every possible problem, but it does
represent some of the more common situations that may occur.
Problem Possible Cause Solution/Items to Check
Display does not light,
and console does not
work
No power to the display
Check that the main circuit breaker for the
display is on.
Check that the display is receiving 100,
120, or 240 VAC power.
No power to the control
console
Ensure the console is plugged into a 100,
120, or 240 VAC power supply.
Exchange the console with a working one,
and enter the correct sport code and/or
radio settings to test. Replace console if
necessary.
Display digits do not
light, but console works
No wired signal from
control console
Check that the display is receiving 100,
120, or 240 VAC power.
Check that the red DS5 LED on the driver
lights up when sending commands from
the controller; see LED Drivers (p� 7).
No radio signal from
control console
Verify that both the console and display
antennas are securely tightened and in a
vertical position.
Keep the console 20–500' (6–152 m) away
from the display. Check that the green
POWER and amber RADIO IN RANGE
indicators on the radio receiver in the
display light up when the control console is
powered on. Move the console 20–30' (6–9
m) from the display and test again.
Replace the radio receiver.
No signal to driver
Check that the display is receiving 100,
120, or 240 VAC power.
Check that the red DS5 LED on the driver
lights up when sending commands from
the controller. See LED Drivers (p� 7).
Exchange the driver with a working one of
the same part #. Replace if necessary. See
LED Drivers (p� 7).
No power to driver
Check that the red DS8 LED on the driver
remains lit up when the display is powered
on. See LED Drivers (p� 7).

Troubleshooting
4
Problem Possible Cause Solution/Items to Check
Display digits light, but
not in the correct order
Incorrect sport code
Ensure the correct sport code is being
used for the display model. Refer to the
appropriate console operation manual.
Incorrect driver address
Ensure all drivers are set to the correct
address. See Setting the Driver Address (p�
9).
Digits light, console
works, but nothing
displays
No wired signal from
control console (see solution on previous page)
No radio signal from
control console (see solution on previous page)
Bad/damaged eld
wiring
Check that the red DS5 LED on the driver
lights up when sending commands from
the controller. See LED Drivers (p� 7).
Display works, but some
LEDs always stay on
Short in digit or indicator
circuit
Exchange the digit/indicator with a
working one of the same part # to verify
the problem. Replace if necessary. See
Replacing Digits (p� 5).
Display works, but some
LEDs do not light or they
blink
Bad connection Verify the connector on the back of the
digit circuit board is secure.
Bad digit or driver
Exchange the digit or driver with a
working one of the same part # to verify
the problem. Replace if necessary. See
Replacing Digits (p� 5) or LED Drivers (p�
7).
Display works, but some
digits do not light
Bad digit or driver (see solution above)
Incorrect sport code (see solution above)
Incorrect driver address (see solution above)
Wrong console
controlling the
scoreboard
Another console’s radio signal may be
transmitting to the display. For example,
two basketball scoreboards in different
gyms that are within 500' (152 m) of
each other. Change the radio settings as
described in Radio Connections (p� 11).
Radio Interference
There may be other radio transmissions in
the area that overpower the console.
If it is not possible to disable the interfering
device, it may be necessary to run a wired
signal connection instead.
Display works, but one
section of digits does
not light
Bad multi-section
connection
Verify power/signal interconnects between
display sections are properly connected.
Refer to appropriate schematic drawings.
Bad transformer
Exchange the transformer with a working
one of the same part # to verify the
problem. Replace if necessary.

Troubleshooting

Component Locations & Access
All internal electronic components and digits are reached by opening a digit panel on
the front of the display.
Digit panels are typically held in place on the
display face by screws. To remove a digit,
simply unfasten the screws and carefully lift it
from the cabinet. The power/signal plug can
then be removed from the connector on the
back of the digit to completely free the digit
and access internal components.
Component location varies with each model, but drivers and power and signal
components are typically mounted inside the cabinet behind a digit panel. To locate
the driver(s), look for a warning label similar to that shown in Figure 4.
Replacing Digits
LEDs are embedded in a circuit board that is
mounted to the back of the digit panel. Do not
attempt to remove individual LEDs. In the case of
a malfunctioning LED or digit segment, replace the
entire digit circuit board. The process of replacing
digits varies by whether it is a PanaView digit or
UniView digit (Figure 5).

1� Open the digit panel as described in Component Locations & Access (p� 5).
2� Disconnect the 9-pin plug from the back of the digit by squeezing the locking tabs
together and pulling the connector free.
3� Use a 9/32" nut driver to remove the nuts securing the digits to the inside of the panel,
and then lift the digit off the stud inserts.
4� Position a new digit over the studs (making sure the small plastic spacers are still in
place), and then tighten the nuts.
5� Reconnect the 9-pin plug. This is a keyed connector and it will attach in one way
only. Do not force the connection.
6� Secure the digit panel to the display face with the screws, and then power up and
test the display to verify the issue has been resolved.

1� Open the digit panel as described in Component Locations & Access (p� 5).
2� Disconnect the 9-pin plug from the back of the digit by squeezing the locking tabs
together and pulling the connector free.
3� Use a 9/32" nut driver to remove the nuts securing the digits to the aluminum
standoffs, and then lift the digit off the standoff/diffuser assembly.
4� Position a new digit over the standoffs, and then tighten the nuts. It may be necessary
to also tighten the standoffs if they became loose while removing the nuts.
5� Reconnect the 9-pin plug. This is a keyed connector and it will attach in one way
only. Do not force the connection.
6� Secure the digit panel to the display face with the screws, and then power up and
test the display to verify the issue has been resolved.
