Electrical Installation 5

Symptom/Condition

Solution/Items to Check

Display doesn't light at all.

 Check all cable connections:

 Power to the light strip controller (or shot clock)
 Signal to the light strip controller (or shot clock) from the

scoreboard controller

 Signal from the light strip controller (or shot clock) to the light

strip itself

 When using an All Sport 5000 Series controller, ensure there is

an address plug on the light strip control driver set to address 1
(refer to Section 4.3).

Note: Setups using an All Sport 4000 or ProSport 6000 controller
do not require this address plug.

 Replace controller driver (refer to Section 4.3).

Light strip comes on at
wrong time.

 Make sure gray wire from J6 is connected to appropriate position

on terminal block inside controller. Refer to Drawing A-176435 in
Appendix A.

Individual LED, or section of
LEDs, is not working.

 Swap section of light strip with one known to work correctly to

verify it is defective.

 Replace defective portion of light strip.

Section 4: Maintenance & Troubleshooting

IMPORTANT NOTES:

1. Disconnect power before doing any repair work on the display.

2. Allow only qualified service personnel access to internal display electronics.

4.2 Component Location & Access

LED end-of-period lighting system components should be located at the scorer's table and at
each backboard. Light strips are mounted directly to each backboard with mounting clips,
and to the scorer's table with hook-and-loop fasteners. The individual parts of the light strips
are directly accessible.

The light strip controller will typically be located on or under the scorer's table or, for
backboard lighting without a shot clock, on the backboard backstop. Power and signal
connections are external, and if necessary, internal components can be accessed by removing
the device's cover.

4.3 LED Drivers

Reference Drawings:

4 Column LED Driver II Specifications.................................................... Drawing A-123783

Mechanical/Electrical Specs- Light Strip Controller ................................ Drawing A-176435

Daktronics LED light strip controllers use 4-column LED drivers to perform the task of
switching LEDs on and off. Refer to Drawing A-123783 in Appendix A for detailed driver
pin out/switch specifications.

Note: The control box used to interface with non-Daktronics equipment does not include
an LED driver.

Replacing a Driver

1. Open the LED light strip controller enclosure by removing the two screws on the bottom

and lifting off the top. Refer to Drawing A-176435 in Appendix A.

2. Disconnect all connectors from the driver by squeezing together the locking tabs and

pulling the connectors free.
