24 Maintenance & Troubleshooting
5.3 Replacing Digits
LEDs are embedded in a circuit board that is mounted to the
back of the digit panel. Do not attempt to remove individual
LEDs. In the case of a malfunctioning LED or digit segment,
replace the entire digit circuit board.
The process of replacing digits varies by whether it is a
PanaView digit or UniView digit (
Figure 10 ).
PanaView
To replace a PanaView digit circuit board ( Figure 11 ):
1. Open the digit panel as described in Section ‎ 5.2 .
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 stud inserts.
4. Position a new digit over the studs (making sure the small plastic spacers are still in
place) and tighten 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.
