Troubleshooting

When troubleshooting driver problems, several LEDs provide diagnostic information. The
number of LEDs and their function depends on the driver type.

While it is necessary to have the display powered on to check the LED status
indicators, always disconnect power before servicing.

Replacing a Driver
1�
Open the digit panel nearest the driver as described in
.
2�
Disconnect all plugs from the driver by squeezing the locking tabs together and
pulling the connectors free. It may be helpful to label the cables or take a picture to
know which plug goes to which jack when connecting the replacement driver.
3�
Remove the nuts securing the driver to the driver tray.
4�
Carefully lift the driver from the display and place it on a clean, flat surface.
5�
Position a new driver over the screws and tighten the nuts.
6�
Reconnect all plugs to their mating jacks on the driver. The connectors are keyed
and will attach in one way only. Do not force the connections.
7�
Ensure the new driver is set to the correct address. This will be the same address of the
old driver being replaced. Refer to
Setting the Driver Address (p� 9)
.
8�
Close and secure the access panel, and then power up and test the display to verify
the issue has been resolved.
