IMPORTANT SAFEGUARDS

 Read and understand all instructions before servicing the scoreboard.  Disconnect display power when not in use or when servicing.  Disconnect display power before servicing power supplies to avoid electrical shock.

Power supplies run on high voltage and may cause physical injury if touched while powered.

 Do not modify the scoreboard structure or attach any panels or coverings to the

scoreboard without the express written consent of Daktronics.

 Do not disassemble control equipment or electronic controls of the display; failure to

follow this safeguard will make the warranty null and void.

 Do not drop control equipment or allow it to get wet.

Project-specific information takes precedence over any other general information found in this manual. Such information may include:

 Shop Drawings: describe mounting methods to structural elements, access method

(front or rear), and power and signal entrance points

 System Risers: describe power and signal connections between display components

and the control location; may also include control room layout and schematic

To request project-specific information, contact a Daktronics sales coordinator or project manager.

1.1 Specifications Label

Power specifications as well as serial and model number information can be found on an ID label on the display, similar to the one shown in Figure 1.

Please have the assembly number, model number, and the date manufactured on hand when calling Daktronics customer service to ensure the request is serviced as quickly as possible. Knowing the facility name and/or job number will also be helpful. Note that the Product Number(s) are sometimes used to distinguish different generations of the scoreboards having the same model number.

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

2.3 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).

PanaView

To replace a PanaView digit circuit board (Figure 6):

1. Open the digit panel as described in Section 2.2.

2. Disconnect the power/signal connector from the back of the digit by squeezing

together the locking tabs and pulling the connector free.
