にしたテレビジョン受像機。A first human power section to which a composite video signal is input, a second human power section to which three primary color signals and a synchronization signal are respectively input, and a second human power section to which the composite video signal and the composite video signal are input by switching selection to the first human power section. a switch section that outputs the formed color difference signal and outputs the synchronization signal and the three primary color signals by selectively switching to the second human power section; In a television receiver comprising a video amplifier section that extracts and outputs a luminance signal from the input composite video signal, the switch section is provided with a bias for sharpness adjustment to the video amplifier section when the selection is switched to the second manual input section. A television receiver that is provided with a switch that cuts off voltage and contrast adjustment bias voltage, and minimizes sharpness and contrast when switching selection to the second human power section.
