レビジヨン受像機。[Claim for Utility Model Registration] A switching circuit that switches and outputs a video signal in the TV mode and a convergence adjustment signal in the convergence adjustment mode based on a mode switching signal between the TV mode and the convergence adjustment mode, and this switching circuit. In a television receiver comprising a video amplification circuit to which an output of the circuit is applied and control voltages for brightness adjustment and contrast adjustment are respectively applied, the brightness adjustment is performed in the convergence adjustment mode based on the mode switching signal. 1. A television receiver comprising a control circuit for lowering the black level of a convergence adjustment signal by controlling at least one of control voltages for contrast adjustment and contrast adjustment.
