徴とするテレビジヨン受像機。[Claims for Utility Model Registration] A television receiver equipped with a channel selection control circuit that outputs a sign color signal for displaying the channel, volume, etc. on the screen and a blanking signal for blanking the video signal portion corresponding to the display portion. , a synchronization signal detection means for detecting the presence or absence of a synchronization signal separated from the video signal and outputting a corresponding detection signal; and based on the output of the synchronization signal detection means, when there is no synchronization signal, the detection signal; A sine mixing circuit generates an output corresponding to at least the remaining portion of the screen other than the display portion as a sine color signal based on the blank signal, the horizontal sync pulse and the vertical sync pulse formed from the sine color signal and the flyback pulse. and an output means for providing the sine mixing circuit, based on the output of the sine mixing circuit,
A television receiver characterized in that when there is no synchronization signal, at least the remaining portion other than the display portion is displayed in a single color.
