26 Scoreboard Troubleshooting
5.2 Component Locations
Component location varies with each scoreboard model. Refer to the component location
drawings in Appendix A. Drivers and power and signal components are typically mounted
inside the scoreboard behind a digit or access panel. There are several ways to locate the
access panels:
Power Warning Label
Look for a power warning label toward the bottom of the access panel (Figure 12). This is the
location of the master driver. Refer to the component locations drawings to determine the
number of drivers for a particular scoreboard model.
Panel Hinges
Access panels typically have raised hinges to allow them to easily swing open.
Conduit
Knockouts
Most scoreboards have knockouts for the electrical and signal conduits on the rear that will
match up with an access panel on the front. Conduits will only run to the master driver.
5.3 Component Access
For front-access scoreboards, all internal
electronic components and digits are reached
by opening an access door or a digit panel on
the front of the display.
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 18.
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.
Note: When closing the access panel, make sure all latches/screws are holding the door
firmly in place to prevent moisture and debris from entering the scoreboard.
