Abstract

PROBLEM TO BE SOLVED: To avoid complaints completely by displaying a cause to power interruption on a screen at application of power except that the user forcibly interrupts power so as to allow the user to recognize the cause to power interruption even when the user depresses an off-timer key in mistake resulting in causing power interruption. SOLUTION: An input video signal (a) is given to a video signal processing circuit 4 and also to a synchronization detection circuit 2, and the result is outputted to a microcomputer 1. The microcomputer 1 incorporates a timer processing section 1-1 to conduct processing such as off-timer processing, and controls a color and size of characters and a display position of them for an on-screen generating circuit 3, and a video signal processing circuit 4 selects an on-screen signal or a video signal and provides an output of the selected signal to a CRT 5. In the case that a function of interrupting power automatically is in operation, the reason is on-screen-displayed for a prescribed time. Furthermore, so long as the user does not depress a key, the display is not automatically put out.
