Abstract: The present invention aims to provide a panel television device with built-in disc loader capable of constantly detecting a mounted state of a disc while alleviating the process of the television section. The panel television device with built-in disc loader has a disc loader section arranged with a disc sensor which state changes according to the detection of the presence of the disc inside, and a sub-microcomputer for performing a disc detecting process based on the state of the disc sensor; and has a television section arranged with a main microcomputer for performing the disc detecting process based on the state of the disc sensor; where drive power is constantly supplied to the disc sensor and the main microcomputer; and the disc detecting process is performed by the sub-microcomputer when the power of the disc loader section is turned ON, and the disc detecting process is performed by the main microcomputer when the power of the disc loader section is turned OFF.

Abstract: A selection operation of a designated channel for a broadcast signal received via an antenna is performed, so that the broadcast signal of the designated channel is detected and the detected broadcast signal is output to a monitor via a video IC and the like. When the power of a microcomputer is turned on (power supply is started), the microcomputer causes a tuner to perform a channel-selection operation for the channel that has been selected at the time of most recent turn-off of the power (power supply stop). As a result of the channel-selection operation, if the tuner cannot detect the broadcast signal of the channel, the microcomputer displays an image of that channel (an image where an video image is not shown) on the monitor and thereafter displays an image for notifying a user of a measure to be taken through an OSD circuit.
