Illuminated PCB Assemblies
The LED assemblies and circuit boards (but not individual LEDs) are field replaceable
parts. Each LED is soldered to a printed circuit board (PCB) which is, in turn, attached
to the detachable aluminum face. The face is attached to the scoreboard cabinet with
self-tapping screws. You will need a 1/4-inch nut driver to remove these screws.
Removing an LED Assembly, Step-By-Step:
•
Disconnect power to the shot clock cabinet before performing any service work.
•
Remove the self-tapping screws holding the face to the cabinet, leaving for last
one of the screws along the top of the face.
•
Support the face with
one hand as you
remove the final
screw.
•
Rotate the face so
that you can see the
PCB (or PCBs)
behind it and the
cable connections
along the back side.
•
Unplug the ribbon
cables from the
PCBs.
Each LED circuit board is
held to the face by several nuts, which you can remove using a 3/8-inch nut driver. Be
careful to keep the PCBs right side up when you return them to the shot clock cabinet.
