ABSTRACT:
The present invention relates to a television power supply control method and circuit and more particularly to a TV power supply control method and circuit which automatically controls the power supply after a predetermined time period has elapsed after a viewer has left a seat and failed to turn off the power to the television. The television switches to an operation standby mode. There is thus no need to turn off the power every time the viewer leaves the room. Not only is an unnecessary waste of power prevented; also, damage to the TV due to overheating can be avoided.
