ン受像機。In a television receiver that performs channel selection by continuously changing the local frequency of the tuner using a local frequency variable means while the AFT is in operation, a horizontal synchronizing signal is detected by a horizontal synchronizing signal detection circuit, and the detection signal is generated. A television receiver characterized in that the monostable multivibrator is triggered to generate a pulse as a tuning instruction signal, and a means for producing audio or visual display on a speaker or a cathode ray tube screen is driven by the pulse for the pulse period. .
