テイング制御回路。[Scope of Claim for Utility Model Registration] A no-signal detection circuit that detects a no-signal state when a synchronizing signal disappears in a video-detected television signal and outputs a video muting control signal; Accordingly, the present invention comprises a switch circuit that outputs a switch signal, and a video blanking signal output circuit that outputs a video blanking signal that applies video blanking to the entire screen of a picture tube of a television receiver using the switch signal. In the video muting control circuit, a power operation circuit that outputs an ON/OFF control signal in response to an ON/OFF operation of a power supply applied to the television receiver from the outside turns on/off the main power of the television receiver. Video muting control, characterized in that it is connected to a power relay circuit and the switch circuit, and the switch circuit is configured to stop outputting the switch signal in response to an OFF control signal to the power relay circuit. circuit.
