When the channel switch is opened after the state ends, the tuning voltage in the channel control means is detected by the tuning output voltage detection means, and a mute output is generated by controlling the mute output switching circuit, and the channel switch is opened. 1. A mute voltage generating circuit that suppresses white nozzle generated from a tuner and mutes a video circuit and/or an audio circuit during a predetermined time required for tape unloading.
