Abstract

본 발명은 텔레비젼 수상기의 표시소자 오동작 방지회로에 관한 것으로서, 채널 절환시 또는 채널자동 선국시에 표시소자(STERO, SAP)에 발생되는 오동작을 방지하는데 있으며, 본 발명의 특징은 음성다중IC(10)의 입력단자(ST,SAP등)에 공급되는 동작전원을 소정시간 동안 지연하느 동작전원 지연수단(20)과, 이 동작전원 지연수단(20)에 의해 작동되어 대기전원부에서 공급되는 전원을 공급받아 시스템에 선택된 방송상태를 외부로 표시하는 표시수단(30)으로 이루어짐을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display element malfunction prevention circuit of a television receiver, and to prevent a malfunction occurring in the display elements (STERO, SAP) at the time of channel switching or automatic channel selection. The operation power delay means 20 for delaying the operation power supplied to the input terminals ST, SAP, etc. for a predetermined time, and the power supplied by the operation power delay means 20 to supply the power supplied from the standby power supply. And display means 30 for displaying the broadcast status selected in the system to the outside.
