It has two cable connec- tors, C1 which carries the display signals, and C2 which connects the power supply. • There are no serviceable components on the dis- play module. A fuse is present, however it is soldered in and failure of this fuse indicates a catastrophic internal failure of the module. • The Display Module is supplied power from the Interface Board. An overload condition of the Display Module (e.g., short) can cause Interface Board failure.
