Figure 4: Power Warning Label
2.2 Component Locations & Access
All indoor scoreboards are front-access, meaning that 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 scoreboard 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 scoreboard model,
but drivers and power and signal components are
typically mounted inside the scoreboard behind a digit
panel. To locate the driver(s), look for a warning label
similar to that shown in Figure 4.
For model-specific component layouts and access
locations, refer to the electrical and signal or component
location drawings attached to the product specifications

Figure 8: 16-ColumnDriver Tray Components
2.4 LED Drivers
In each scoreboard, one or more LED drivers perform the task of switching LEDs on and off.
LED drivers are mounted to a driver tray. Refer to Figure 8 to view the typical components of
a Tuff Sport driver tray.
All Tuff Sport scoreboards and statistics displays use 16-column drivers (Figure 8), while
some smaller displays use 4-column drivers. Several scoreboard models contain more than
one driver to accommodate all of the digits and indicators. Refer to the drawings attached to
the product specification sheets listed in Appendix A to determine the type and number of
drivers for a particular scoreboard model. Also refer to Appendix B to find the scoreboard’s
schematic drawings.

Note: While it is necessary to have the scoreboard powered on to check the LED indicators,
always disconnect scoreboard power before servicing.
16-Column “Gyrus” Drivers
16-Column Drivers (prior to April 2015) & 4-Column Drivers
Multiple Drivers
Scoreboards that require multiple drivers operate using a primary/secondary driver
configuration. The two drivers have been designed to simply plug into one another, and this
is done at the factory, so no additional on-site connection is necessary.
If it appears as though only a certain group of digits on the scoreboard is not functioning,
there may be a problem with the secondary driver(s) or the power/signal connection from
the other driver(s).
Note: The BB-2117 and BB-2119 require an interconnect cable between their driver
and the driver in the BB-2116. Refer to appropriate schematics listed in Appendix B.

Replacing a Driver
If the driver status indicators do not appear to be working correctly, it may be necessary to
replace the driver.
1. Open the digit panel or scoreboard face panel as described in Section 2.2.
2. Disconnect all connectors from the driver by squeezing together the locking tabs and
pulling the connectors free. It may be helpful to label the cables to know which cable
goes to which connector when reattaching the driver.
3. Remove the wing nuts securing the driver to the driver tray.
4. Carefully lift the driver from the display and place it on a clean, flat surface.
5. Position a new driver over the screws and tighten the nuts.
6. Reconnect all power/signal connectors.
Note: The connectors are keyed and will attach in one way only. Do not attempt to
force the connections.
7. Ensure the driver is set to the correct address (refer to Setting the Driver Address).
8. Close and secure the access panel, then power up and test the scoreboard to see if
changing the driver has resolved the problem.
Setting the Driver Address
Since the same LED drivers can be used for many scoreboard models, each driver must be set
to receive the correct signal input, or address, for the model being used. The way the address
is set depends on the driver type:
For 16-column “Gyrus” drivers, addresses
For older 16-column and 4-column drivers, addresses
10 Scoreboard Troubleshooting
are set through the S2 (L) and S3 (H) rotary
switches on the driver (Figure 9) using a
small flathead screwdriver.
Refer to the tables on the following pages to
determine the correct address setting of the
driver(s) in a particular scoreboard model
and see Drawing B-1198765 in Appendix C
for addressing information of driver
addresses 1 – 255.
are set with jumper wires in a 12-pin plug which mates
with jack J19 on the driver (Figure 10).
It may be possible to reuse the same address plug from
the driver that was replaced. If not, first refer to the
table on the following page to determine the correct
address setting of the driver(s) in a particular
scoreboard model. Then see Drawing A-115078 in
Appendix C for a listing of the wire/pin connections
for driver addresses 1 – 128.

2.5 Radio Connections
To determine the settings for radio connections between the scoreboard and control console:
1. Power off any radio-equipped consoles in the area.
2. Cycle power to the scoreboard, and watch for the radio settings. These settings
appear in different locations based on the scoreboard layout:
When using the All Sport 5000
controller, the scoreboard will
display “bX CY” where X is the
Broadcast group number and Y is
the Channel number. The default is
b1C1.
o If there is a clock, the settings
appear in the first four clock
digits (Figure 11).
o If there is no clock, the settings
should appear in the Home and
Guest score digits, but this may
vary by scoreboard model.
When using the RC-100 controller,
the scoreboard will display “CXX”,
where the XX is a channel from 0115 (Figure 12). The default is
channel 01.
Note: If these settings do not appear, the radio receiver may need to be
repaired/replaced.
To make sure the console radio settings match the receiver in the scoreboard, refer to the
appropriate control console manual.
All Sport Radio Settings RC-100 Radio Settings
Radio Interference
If it has been determined that a nearby scoreboard’s radio signal is interfering, the settings of
the radio receiver or wireless base station inside the scoreboard(s) must be changed.
1. To locate the radio receiver or base station, simply look for the black antenna sticking
out the front of the scoreboard. Component location drawings also show the exact
position where the radio receiver will be mounted.
2. Open the access panel to which the receiver is attached as described in Section 2.2.
The channel selection process varies depending on whether the scoreboard is equipped with
or a radio receiver (All Sport 5000) or a wireless base station (RC-100).

to test the radio connection.
For more information, refer to the Remote Control System RC-100 All Sport Operation Manual
(ED-15133).
2.6 Segmentation & Digit Designation
In each digit, certain LEDs always go on and off together. These groupings of LEDs are called
segments. Drawing A-38532 in Appendix C details which connector pin is wired to each digit
segment and the wiring color code used throughout the scoreboard.
The Electrical and Signal drawings and Component Location drawings also specify the driver
connectors controlling the digits. Numbers shown in hexagons in the upper half of each digit
indicate which connector is wired to that digit.
2.7 Schematics
For advanced scoreboard troubleshooting and repair, it may be necessary to consult the
schematic drawings. Listed in Appendix B, schematic drawings show detailed power and
signal wiring diagrams of internal display components such as drivers, horn interface cards,
and transformers as well as optional components like TNMCs, radio receivers, and end of

2. Permit only qualified service personnel to access internal display electronics.
3. Disconnect power when not using the scoreboard.
3.1 Display Overview
Team Name Message Centers (TNMCs) are programmable LED displays that allow users to
show custom Home and Guest names or messages of ~15 characters on the scoreboard in
place of static vinyl captions. TNMCs are typically ordered factory-installed, but they may
also be field-mounted after the scoreboard is in place. Characters are shown on one line using
single- or double-stroke fonts.
Electronic captions, on the other hand, are pre-programmed to only show specific labels to
match the captions for a particular sport mode, making it much simpler to switch between
sports. Characters are shown on one line using single-stroke fonts.
Primary matrix size is 8x48 with 0.75" pixel spacing. Figure 16 shows examples of both
TNMCs and electronic captions.
* Weight shown is for a pair of displays.
** Only used on BB-2116 and H-2101.
*** Only used on tennis scoreboards.
One or more LEDs on a single
module fails to light or turn off
Check/replace the ribbon cables on the module.

or is garbled
Replace the first module (see Section 3.6).
Replace the display driver (see Section 3.6).
A group of modules which shares
the same power supply assembly
fails to work
Replace the power supply assembly (see Section 3.6).
Entire display fails to work
Check for proper line voltage into the power termination panel.
Check/replace the ribbon cable to the modules.
Check the voltage settings on the power supplies.
Check/replace the signal cable to the display driver.
Replace the display driver (see Section 3.6).
3.2 Initialization Information at Startup
Every time the display is powered up and there is no All Sport® signal present, the display
will run through an initialization process, during which it will test all LEDs and addresses.
First, the message center will display the proper address number.
If the entire display fails at startup, power may not be properly connected, or the address
setting may not be correct on the display driver. Check both in the event of a failure.
3.3 Display Troubleshooting Table
The table below lists potential problems with the display and indicates possible causes and
corrective actions. This list does not include every symptom that may be encountered, but it
does present several of the most common situations that may occur.
Many of the solutions offered below provide references to other sections within this manual
with further detail on how to fix the problem.
If a problem occurs that is not listed or that cannot be resolved using the solutions in the
following table, contact Daktronics using the information provided in Section 4.
Refer to Drawing B-1132254 or B-1133209 in AppendixB for detailed schematics about
display power and signal routing.
Display signal routing can be summarized as follows:
1. Data from the All Sport
(or radio) into the scoreboard.
2. The signal then travels through the driver, typically re-driven from the driver TB-31 to
the current loop interface (CLI) cards located on the right-hand module of each display
and then to the first LED module via ribbon cable.
3. The signal relays from module to module via ribbon cable in daisy-chain style until it
reaches the last module in the display.
Display power routing can be summarized as follows:
1. Incoming power from the power cord terminates at the main scoreboard LED driver tray.
2. Using interconnect harnesses, the power for TNMCs is passed from the driver tray to
the Home display power supply, and then to the Guest display power supply. In stat
display electronic captions, each power supply receives power from a separate driver.
3. Power from the power supplies is relayed to all display modules.
4. The modules draw their power directly from the power supply assemblies; the
display driver receives power out from the first module via ribbon cable.

3.5 Component Locations & Access
To access the internal components of the display, simply remove the screws on either side
of the face panel that secure it to the scoreboard. Carefully remove the face panel from
the scoreboard, as there will be several cables connected to it. Drawings B-1130367 and
B-1130784 in Appendix C provide a detailed view of each display component and the
connections between them.
3.6 Replacing a Component
1. Access the internal components as described in Section 3.5.
2. Disconnect all power/signal cables from the component by squeezing together the
locking tabs and pulling the connectors free. It may be helpful to label the cables to
know which cable goes to which connector when reattaching.
3. Remove the hardware securing the component to the display face panel.
Note: In order to replace the right-most module circuit board (when viewing the
display from the front), the power supply bracket and driver circuit board must be
removed from it first.
4. Position a new component on the display face panel and tighten the hardware.
5. Reconnect all power/signal connectors.
6. Power up and test the scoreboard/display to see if the problem has been resolved.
Refer to Figure 17 for display assembly, showing the power supply, driver, and modules.

and off when there is no current loop (CL) signal
Figure 17: Display Assembly, Top View
Figure 18: Display Driver
3.7 Display Drivers
Display drivers, also known as controllers
or shift cards, use a 12-pin plug that
mates with jack J4 to set the address.
For TNMCs, the address plug is set to 1
(221). A typical Player-Foul-Points
electronic caption for statistics displays
uses address 3 (223) while a scoreboard
with electronic captions uses address 8
(228). Pin 11 on the address plug selects
whether to show Home data (connected)
or Guest data (not connected). Refer to
Drawing A-123794 in Appendix C for
addressing information.
Note: Refer to Drawing A-3019367
for TNMC addressing information of
tennis systems with up to 12 courts.
Figure 18 illustrates some of the primary jacks and indicators of a display driver.
Diagnostic LEDs
The following table explains the functions of the primary diagnostic LEDs on the drivers:
Power Supply; 5V @ 10A, 85-264VAC (for 0.75" mods)
A-1568
Cable; 18 pos, Ribbon, 6"
W-1320
3.8 Display Maintenance
Complete a yearly inspection to maintain safe and dependable display operation.
This inspection should address the following issues:
Loose Hardware: Verify that fasteners, such as bolts and rivets, have not come loose.
Check and tighten or replace fasteners as required.
Excessive Dust Buildup: It may be necessary to occasionally vacuum the inside of
the display cabinet to remove dust/dirt buildup that may interfere with airflow.
Corrosion: Check the paint, and look for possible corrosion
Make repairs or take corrective action immediately if any of the preceding conditions are present.
3.9 Replacement Parts List
The following table contains display components that may have to be replaced. Many of the
components within the display itself have attached part number labels.
