Field of the Invention The present invention relates to an automatic channel search apparatus and method for television, comprising: tuner means 56 for tuning a broadcast signal transmitted from a broadcast station, and audio signals of the broadcast signal tuned by the tuner means 56; The control panel 50 in a television comprising audio processing means 58, 60, 62, 64 for processing and video processing means 66, 68, 70, 72, 74 for processing the video signal of the broadcast signal. When the automatic channel search mode is set for the television, the automatic channel search mode generated by the OSD processing unit 78, the automatic channel search mode, and the channels targeted for the automatic channel search are sequentially displayed. Under the automatic channel search mode, the channel for which the synchronization signal is detected while applying the tuning voltage from the lower channel to the upper channel based on the tuning data stored in the channel data storage 76 under the control of the control unit 52 is selected. Following the search, the channel is searched for the synchronization signal detected by applying the tuning voltage from the upper channel to the lower channel, and the channels are highly ordered by the tuning of the tuning voltage during automatic channel searching. The search is executed.
