20 Scoreboard Troubleshooting
5.3 Replacing Digits
LEDs are embedded in a circuit board that is mounted to the back of a digit panel, as shown
in
Figure 14 . Do not attempt to remove individual LEDs. In the case of a malfunctioning
board, replace the entire digit circuit board.
To replace a digit circuit board:
1. Open the digit panel as described on the previous page.
2. Disconnect the power/signal connector 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 aluminum
standoffs, and then lift the digit off the standoff/diffuser assembly.
4. Position a new digit over the standoffs, and tighten the nuts. It may be necessary to
also tighten the standoffs if they became loose while removing the nuts.
5. 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.
6. Secure the digit panel to the display with the two screws, then power up and test the
display to see if changing the digit has resolved the problem.
