Signal Process Start-up Circuit

F+15V is the only voltage needed from the power supply to activate the signal process circuit.
F+15V is the source of a DC-DC converter circuit in the DA board which output supplies all the
different circuits involved in the processing of the signal.
Note: Turning on the Display's Main power switch, turns on the Tuner Box. Turning it off does not turn
off the Tuner Box. (This is true for wired or wireless connection).
