In the Daktronics DistaView LED outdoor scoreboards, digits are attached to the
hinged doors on the front of the scoreboard. Refer to Component location
drawings for more details.
Component location varies with each scoreboard model, but drivers and power and
signal components are typically mounted inside the scoreboard behind an access
panel or a digit.
With a non-digit access panel, simply remove the top, side and bottom screws
holding it in place. Some panels are hinged and swing open when the screws are
removed or loosened.
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.
Replacing a Digit
The digit circuit board, the platform for the LEDs, is mounted to the back of the digit
panel. See
Figure 7
below. Do not attempt to remove individual LEDs. In the case
of a malfunctioning board, replace the entire digit panel.
To remove a scoreboard digit, follow these steps:
1. Open the digit panel as
described in the preceding
section.
5-2 Scoreboard Maintenance
and Troubleshooting
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.
3. The digits are secured to the
inside of the panel with fixed
machine screws, spacers, and
push nuts. Remove the nuts and
lift the digit off the standoff
screws. (The push nuts can be
removed in several ways, but
Daktronics recommends using a
9
/
32
" nut driver.)
4. Position a new digit over the
screws and tighten the nuts.
5. Reconnect the power/signal
connector.
Note: This is a keyed connector
Β it will attach in one way only. Do not attempt to force the connection!
