Abstract
A system for selectively illuminates a light source that illuminates a power indicator of a video apparatus when the indicator distracts a viewer. The power button illumination is selectively set to be extinguished or illuminated when the video apparatus is powered on by means of an on-screen menu as an example. Extinguishing the power button light source does not affect the ability of the indicator to become illuminated to provide information to a viewer regarding the operating status of the video apparatus such as when a TV projection lamp has failed.
