In this method, when the TV is turned on or a channel is selected, the window AFT value and channel AFT value for the corresponding channel are windowed, and when the channel AFT value is out of the windowing range, the user can display an abnormal antenna. In response to the first control signal, the apparatus selects and demodulates a desired signal from a broadcast signal propagated from a broadcasting station, demodulates and outputs a composite video intermediate frequency signal, and amplifies the input composite video intermediate frequency signal. Video intermediate frequency processing means for separating and outputting a video and audio signal, a first ALGI ratio signal, and a second ALGI ratio signal processing the video signal, and outputting a mixed ALGI ratio signal to drive means for driving the display device. Outputting a first control signal in accordance with a video signal processing means and a channel request signal, AFT means for windowing the modern AFT value detected from the false signal with the reference AFT value and outputting a first AL ratio signal indicating that the antenna is abnormal when it is out of the windowing range. When an abnormality occurs in an antenna such as a poor contact or an antenna is misaligned due to various reasons, there is an effect of detecting and displaying it to the user.
