How to Replace the Lamp in a Mitsubishi DLP TV
Digital Light Processing television's (DLP television) crystal-clear picture quality is based on a replaceable mercury-vapor metal halide arc lamp unit. Lamp units are designed to last between two and three years before they begin to dull or burn out. Once the lamp begins to become dull or burn out, you must replace the lamp to keep your Mitsubishi DLP television working well.
