摘要

The present invention relates to a TV, and in particular, to provide a TV and an external device status notification method having an external device status notification function capable of promptly responding to the user by inputting the input status of various external devices connected to the TV. The TV having the external device status notification function of the present invention includes a tuner unit for selectively amplifying a radio wave of a channel to be received and converting the signal into an intermediate frequency signal of video and audio, and an original color difference in an output signal of the tuner unit. A television receiver comprising a chroma circuit section for extracting a signal, an R, G and B driver section for converting a color difference signal output from the chroma circuit section into a signal for display on a CRT, and a microcomputer for controlling the entire system. An external device input unit for connecting an external device to a television system, a first switching unit for selectively outputting a signal input from a VCR among the external devices and a signal output from the tuner unit to the chroma circuit unit under the control of the microcomputer; Signal output from audio device among external devices and output through chroma circuit unit Is configured to include a display device for display and a second switching unit for outputting the selected audio signal, and if inappropriate to detect the state of the external input device to the user,
