18 Scoreboard Troubleshooting
4.3 Replacing Digits
Digits consist of a circuit board with embedded LEDs mounted to a black polycarbonate tray
and encased in protective gel as shown in Figure 19. 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.
To replace a digit:
1. Open the digit panel as described in Section 4.2.
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.
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.
