Abstract: A liquid crystal display projector for projecting images on a screen. The projector includes a projector body and an optical projection system positioned generally within the projector body. A releasable first self-aligning lamp socket for receiving a first end of a longitudinal replaceable bulb and a releasable second self-aligning lamp socket for receiving a second end of a longitudinal replaceable bulb are mounted on a hinged platform coupled to the projector body. The platform has a first position where the platform swings the bulb outside of the projector body and a second position where the platform swings the bulb into an interior position inside the projector body optically aligned with respect to the optical projection system.
