Abstract
Abstract A television set has a satellite broadcast receiver which includes a BS converter and a BS tuner. A power supply voltage is selectively supplied from the BS tuner to the BS converter. The BS tuner has a selector switch for selecting an "ON" mode in which the power supply voltage is to be supplied on the BS converter, or an "OFF" mode in which the power supply voltage is not to be supplied to the BS converter. A control unit in the BS tuner displays on a CRT a message indicating that the power supply voltage is not supplied to the BS converter if the selector switch is selecting the "ON" mode and no BS program is being received.
