するカラーテレビジヨン受像機。 A capacitor that is charged by an internal DC power source during power input operation, a means for electrically disconnecting the capacitor from the internal DC power source due to a voltage drop in the internal DC power source, and a means for electrically disconnecting the capacitor from the internal DC power source due to the electrical disconnection, and operating by being electrically connected by the electrical disconnection. After the power to the receiver body is turned off, the charge stored in the capacitor is transferred to the horizontal blanking circuit or the vertical blanking circuit and the luminance signal amplification circuit via the switch means. What is claimed is: 1. A color television receiver configured to supply
