ABSTRACT:
Disclosed is a power supply source control apparatus for a satellite broadcast receiver. The voltage supplied to the outdoor-installed satellite broadcast receiving facilities is compared with a reference voltage to detect whether there is an extraordinary state such as a short circuit in a power source. In response to the detected signal, a signal for disconnecting the power supply voltage is generated. At the same time, a display device is made to operate to inform the user of the power failure.
