Abstract
An image display device capable of reducing power consumption with improved effectiveness even when a sync signal sensor fails to sense both horizontal and vertical sync signals, wherein when a first sync signal sensor fails to sense both horizontal and vertical sync signals, a main power source, a heater power source device, and a first sync signal sensor power source device are turned off. Power is thus saved. When a second sync signal sensor senses at least one of the horizontal and vertical sync signals, the first sync signal sensor power source device that was turned off is turned on.
