The outside screen is called a linticular lens and the inside one is the fresnele lens. They both should come out together from the front as the trim on this set if im not mistaking pulls or slides off then theres mounting plates holding it on. Becarefull and dont try to clean the mirror as the coatings on the outside of the mirror. Also be very carefull not to touch any componets as theres extremly hi voltage in these sets even with them unplugged. Good Luck
