Scoreboard Maintenance & Troubleshooting
LEDs are embedded in a circuit board that is
mounted to the back of the digit panel, as
shown in Figure 21. 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 5.1.
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 inside of
the panel, and then lift the digit off the
standoff screws.
4. Position a new digit over the screws,
making sure the rubber side of the
rubber-backed washer on the standoff
screws is facing the digit circuit board.
5. Tighten the nuts.
6. Reconnect the power/signal connector.
7. Close and secure the digit panel, then power up and test the scoreboard to see if
changing the digit has resolved the problem.
Scoreboards with 8-column drivers use a single transformer, while 16-column driver
enclosures require a dual transformer assembly.
To remove a transformer:
1. Open the access panel as described in Section 5.1.
2. Locate and disconnect all wires connected to the transformer (Figure 22).
3. Use a 9/32" nut driver to remove the hardware securing the transformer.
4. Fasten the new transformer in place and reconnect all wires.

Note:
This is a keyed connector and it will attach in
one way only. Do not attempt to force the connection.
