Abstract

본 발명은 텔레비젼 수상기의 채널전화시에 CRT(Cathode-ray tube)로부터 잡음신호가 출력되는 것을 방지할 수 있도록 된 텔레비젼 수상기의 채널전환시의 영상뮤트 장치에 관한 것으로, 영상신호를 처리함과 더불어, 수평화상의 위상이 안정한 상태에서는 수평구동부를 구동하도록 된 메인 IC와, 이메인 IC의 수평구동을 안정화시키기 위한 필터부를 구비한 텔레비젼 수상기에 있어서, 상기 메인 IC로 부터 출력되는 동기신호에 따라 상기 필터부와 메인 IC의 결합노트의 전위를 로우레벨로 스위칭하는 스위칭 수단을 포함하여 구성된 것을 특징으로 한다.The present invention relates to an image mute device for channel switching of a television receiver, which is capable of preventing noise signals from being output from a CRT (Cathode-ray tube) during channel telephone of a television receiver. A television receiver comprising a main IC configured to drive a horizontal driving section and a filter section for stabilizing horizontal driving of an e-mail IC in a state where a horizontal image is stable in phase, in accordance with a synchronization signal output from the main IC. And switching means for switching the potential of the combined portion of the filter unit and the main IC to a low level.
