Daktronics DF-1030 - Manual (Page 30)

For the front-access modules in this series, opening the hinged access doors on the
front of the display or removing one of the digits can reach all internal electronic
components and digits.
For the 13”, 18” and 24” displays the hinged door swings outward when the two
screws on the display face panel are removed, as shown in Figure 14. For the large
displays, the enclosure is reached by removing one of the digits from the face of the
display. Since component placement varies slightly with each DataMaster model,
consult the Electrical and Mechanical Specifications Drawings.

Note: Disconnect power before servicing the display! Disconnect power, too,
when the display is not in use. Prolonged power-on may shorten the life of some
electronic components.
4.3 Service and Diagnostics
Replacing a Digit
The digit circuit board, the platform for the LEDs, is mounted to the back of the digit
panel. Do not attempt to remove individual LEDs. In the case of a malfunctioning
board, replace the entire digit panel (13” and 18” displays). Refer to Figure 15 for the
digit assembly.
To remove a display digit, follow these steps:
1. Open the digit panel as described in the preceding section.
2. Disconnect the power/signal connector from the back of the digit. Release
the connector by squeezing together the locking tabs as you pull the
connector free.
