Abstract

PURPOSE: To manufacture and design a printed circuit with its area reduced by reducing the number of wirings until a service switch in a switching unit which stops temporarily the operation of a video signal and vertical deflection at the time of setting the cut-off level of the CRT of a color TV receiver.
CONSTITUTION: The anode of diode 14 is connected to the video line of video amplifier circuit 3 of the color TV receiver, and the anode of diode 15 is to the vertical signal line of vertical synchronizing circuit 5 with cathodes of both diodes 14 and 15 connected in common. Then, DC power supply 17 is connected via resistance 16 from the intersection of this common connection, and service switch 19 is provided between the connection point between both diodes 14 and 15 and the ground. At the time of the out-off adjustment of CRT8, switch 19 is closed to make diodes 14 and 15 conductive, thereby temporarily stopping video signals and vertical deflecting signals applied to CRT8.
