Figure 4: Component Location Labeling
Figure 5: LED Digit Panel
2.2 Component Locations & Access
Component location varies with
each scoreboard model. Refer to
the component location drawings
attached to the product
specification sheets listed in
Appendix A. For component
locations of scoreboards with white
digits and Modular Football
Scoreboards, refer to the tables in
Appendix A.
All internal electronic components
are reached by opening a digit
panel or an access door.
Look for labels similar to those shown in Figure 4 to access primary scoreboard components.
Note that the same labels are on both front and rear access panels.
Digit panels are held in place on the
scoreboard face by an offset flange
across the top and by screws at the
bottom, as shown in Figure 5.
To open a digit panel:
1. Hold the digit panel in
place by putting hand
pressure on it and remove
the holding screws.
2. Carefully lift the panel
away from the scoreboard,
sliding it out and down.
Note: If the panel is not
held in place when the
screws are removed, it
could drop and possibly
damage LEDs or the digit
harness.
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.
Rear access panels can be lifted up and out over the screws through keyholes.
Note: When closing a digit or access panel, make sure all screws/latches are holding it
firmly in place to prevent moisture and debris from entering the scoreboard.

2.3 Replacing Digits
Digits that are 18" or smaller have LEDs embedded on a single circuit board that is mounted
to the back of a digit panel, as shown in Figure 6. Newer weather-sealed digits consist of a
digit circuit board mounted to a black polycarbonate tray and encased in protective gel as
shown in Figure 7. Multiple digits may also be secured to a single face panel. Do not attempt
to remove individual LEDs; in the case of a malfunctioning LED or digit segment, replace the
entire digit circuit board.
To replace a digit circuit board:
1. Open the digit panel as
described in Section 2.2.
2. Disconnect the power/signal
plug from the back of the
digit by squeezing together
the locking tabs and pulling

Digits that are 24" or larger are composed of seven
circuit board segments. As with smaller digits, the digit
segment circuit boards are mounted to the back of the
digit panel (Figure 8). Do not attempt to remove
individual LEDs; it may be possible to make repairs by
removing just the defective segment.
To replace a digit segment:
1. Open the digit panel as described in Section 2.2.
2. Disconnect the 2- or 4-pin power/signal
connectors from the back of the digit segment by
squeezing together the locking tabs and pulling
the connector free.
