Modules
Each module assembly consists of a module housing (containing LEDs and the driver)
and a louver assembly. Individual components such as louvers can be removed for
service, but Daktronics recommends that the module be kept intact and that the entire
assembly be sent in for repair or replacement.
Replacing a Module
To replace a module from the front:
1�
Follow the steps as described in Front Access (p�22) .
2� Carefully disconnect all power and signal cables. It may be helpful to label the
cables or take a picture to know which cable goes to which connector when
reattaching a module.
3� Position a new module on the front of the display frame and reconnect all power
and signal cables.
4� Re-latch the fasteners.
5� Power up and test the scoreboard/display to verify the issue has been resolved.
To replace a module from the rear:
1�
Follow the steps as described in Rear Access (p�23) .
2� Use a 1/8" hex wrench to loosen the latch fastener assembly ( Figure 22 ). Turn each
fastener 1/4 turn. *Do not over turn the fastener!*
3� While holding onto the module, push it out and turn it in such a manner (generally a
sideways, diagonal turn) that it can be pulled back through the frame opening.
4� Carefully disconnect all power and signal cables. It may be helpful to label the
cables or take a picture to know which cable goes to which connector when
reattaching a module.
5� Reconnect all power and signal cables to the new module and push it back through
and out the front of the display frame.
6� Re-latch the fasteners.
7� Power up and test the scoreboard/display to verify the issue has been resolved.
