Abstract

PURPOSE:To release forcibly blanking and muting by detecting unlocking when a broadcast signal is not locked for a fixed time or longer by the AFT operation in case of channel selecting operation. CONSTITUTION:When channel selecting operation is performed by a key device 22, the video image blanking and muting operation are attained. When a channel selecting voltage is applied to a tuner 1 by a channel selection voltage generating circuit 23, the channel selection operation is attained and the AFT operation is performed by an AFT circuit 24. When the broadcast signal is locked by the AFT operation, a blanking/muting release instruction is applied to a muting signal generating circuit 25. When the absence of the broadcast signal in the AFT locking range continues for a fixed time, a timer 15 gives an output and even if the broadcast signal is not locked to an effective television signal by the AFT, the blanking and muting are released. Thus, it is prevented that the blanking/ muting operation at channel selection operation are regarded as a fault.
