Maintenance and Troubleshooting

Replacing a Driver
Drivers are typically mounted
inside the scoreboard and
immediately behind a digit,
but location and mounting
varies with the model of the
scoreboard. For the location
of your scoreboard driver,
refer to the
component
locations drawings in your
scoreboard manual.
Each driver is enclosed with a
power supply and signal
terminal block. To reach a
failed driver, you must open
the driver enclosure. Follow
these steps:
1. Open the digit panel
or scoreboard face panel as described in the previous section.
2. Remove the cover from the driver enclosure.
3. Disconnect all connectors from the driver. Release each connector by
squeezing together the locking tabs as you pull the connector free.
Note: When reconnecting, remember that these are keyed connectors and
will attach in one way only. Do not attempt to force the connections.
4. Remove the screws, nuts, or wing nuts securing the driver to the inside of
the enclosure. Refer to
Figure 9 below.
5. Carefully lift the driver from the display and place it on a clean, flat surface.
6. Follow steps 1 through 5 in reverse order to attach a new driver.
