<p>An automatic preset mode is to be automatically executed when a television receiver is purchased, a power source is plugged in, and the power is turned on. Also, various information is to be displayed by OSD (on-screen display) during operation or on completion of operation of the television receiver, so as to allow a user to visually check the operating state. Therefore, when a power supply plug socket (17) is inserted and then a power supply switch of a power supply circuit (16) is turned on, the channel of broadcast allocated to a specified station is detected by a synchronizing signal and an AFT voltage, thus automatically presetting a non-volatile memory (10). During the preset operation, a message indicating that it is now in operation and a message indicating the operating state are displayed on a CRT (3). On completion of all the preset operation, a message of operation completion is displayed.</p> |
