Abstract

PURPOSE:To prevent a reception channel from changing by fixing a channel- selection stop voltage when switching to a video input is done, as to a TV receiver that controls selected channels by making use of a synchronizing signal and a defeat voltage obtained by detection. CONSTITUTION:Channel selecting circuit 7 connected to automatic channel selection tuner 1 stops a sweep with the output of synchronous separating circuit 4a. With switch 3' placed at the side of video input terminal 10, electric current flows from battery 11 to turn on transistor 25. At this time, defeat voltage 8 is low and a change in channel can be prevented.
