。[Claims for Utility Model Registration] (1) The output signal of a down converter installed in a satellite broadcast receiving antenna is input via a coaxial cable, and the broadcast signal of the channel specified by the control unit is selected, amplified, and detected. The down converter demodulates and outputs video and audio signals, and is equipped with a display panel that displays reception channel numbers and other information based on the output of the control section. The satellite broadcasting receiver is equipped with an overcurrent detection circuit between the output of the power supply unit that supplies the downconverter and the chiyoke coil, and when the detection circuit detects a current exceeding a predetermined value, the downconverter What is claimed is: 1. A satellite broadcasting receiver characterized in that a power supply supplied to the receiver is cut off, a detection output thereof is supplied to the control section, and a symbol mark of an antenna provided on a display panel is displayed blinking based on the output of the control section. (2) The satellite broadcasting according to claim (1), wherein when the antenna symbol mark on the display panel is displayed blinking based on the detection output of the overcurrent detection circuit, other displays on the panel are turned off. Receiving machine.
