ヨン受像機。[Claims for Utility Model Registration] A television receiver that has an external input terminal and is used by switching between a reception mode in which a television signal from normal broadcasting is displayed and an external signal display mode in which an external signal from the external input terminal is displayed. a signal switching means for inputting the external signal and the television signal and selectively outputting one of them; a signal determining means for determining the presence or absence of a synchronization signal based on the output from the signal switching means; mode determining means for determining whether it is an external signal display mode; and when a signal for determining the external signal display mode is output from the mode determining means and a signal for determining the absence of a synchronizing signal is generated from the signal discriminating circuit; 1. A television receiver comprising means for displaying an external signal display mode on a screen.
