ABSTRACT:
A microprocessor commonly receives at an A/D port the potentials of the power supplies output from a plurality of types of power supplies (a power supply for HDMI, a power supply for LSI, a power supply for an audio driver IC, and a power supply for a tuner). The A/D port receives the potential of the voltage on an output line of the power supply for HDMI that is divided. If that the potential of the divided voltage is lower than a set potential is detected, the output line is interrupted to interrupt power supply voltage supplied to external equipment.
