Scoreboard Troubleshooting 7
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
the connector free.
3. Use a 9 /
32
" nut driver to
remove the nuts securing the
digits to the inside of the
panel, and then lift the digit
off the standoff studs.
4. Position a new digit over the
studs, making sure the rubber
side of the rubber-backed
spacer is facing the digit
circuit board. Weather-sealed
digits do not require spacers.
5. Tighten the nuts.
6. Reconnect the power/signal
connector.
Note: This is a keyed
connector and it will attach in
one way only. Do not attempt
to force the connection.
7. Close and secure the digit
panel, then power up and test
the scoreboard to see if
changing the digit has
resolved the problem.
