Lenses

The screen with the "swirls" on it is the fresnel lens and that is the one that goes in back then the lenticular lens goes next (it has the feel of a grid to it). Then the screen proetector goes on the very front. The fresnel lens only works installed one way. On Sony TV's look for the orange tag with the part number on it and put that to the lower right facing outword and usually 99% of the time this is how they go back in.
