TNMC Troubleshooting & Maintenance 35
7.7 Modules
Display modules consist of LEDs embedded in a circuit board. One or more circuit boards are
mounted to the back of a display face panel. Do not attempt to remove individual LEDs. In
the case of malfunctioning LEDs, replace the entire module circuit board.
Replacing Modules
1. Access the internal components as described in Section
‎
7.5 .
2. Carefully disconnect all ribbon cables from the driver by squeezing together the
locking tabs and pulling the connectors free.
Note: It may be helpful to label the cables to know which cable goes to which
connector when reattaching.
3. Remove the nuts securing the module circuit board to the face panel. If a display
driver is attached to the module, remove it along with the screws and standoffs.
4. Position a new module on the front of the face panel and reconnect all ribbon cables.
5. Reattach the module to the face panel. If a display driver was previously removed
from the module, reattach it at this time too.
6. Power up and test the scoreboard/display to see if the problem has been resolved.
