Abstract
There is provided a rear projection television having a construction which facilitates replacement of a light source lamp and repair work within the body. The rear projection television includes a screen panel disposed at the front of a cabinet thereof, for receiving projection light projected from behind for image display, to thereby display an image thereon, a light source lamp removably disposed within the cabinet, for projecting the projection light, and a working door provided in the front face of the cabinet. An opening-detecting sensor detects opening of the working door and outputs an opening-detecting signal. An illumination section for replacement work disposed within the cabinet illuminates the inside of the body. The control section causes the illumination section to light when the opening-detecting signal is outputted by the opening-detecting sensor.
