とを特徴とするテレビジヨン受像機。[Claims for Utility Model Registration] (1) In a television receiver having a synchronization detector that responds to a detection output signal of a video intermediate frequency signal, a switch that is turned on and off in response to the output signal of the synchronization detector is provided. A television receiver, characterized in that the detection output signal is provided in a path to a synchronous separation/deflection circuit. (2) In a television receiver having a synchronization detector that responds to a detection output signal of a video intermediate frequency signal, a switch that is switched and controlled in response to the output signal of the synchronization detector is connected to a synchronization separation circuit for the detection output signal. A synchronous signal generator is provided in the path to the synchronous separation/deflection circuit, and when the switch does not select the detected output signal, a synchronous signal generator is provided to send a synchronous signal to the synchronous separation/deflection circuit via the switch. Characteristic television receiver.
