This step opens up the optical parts that were probably originally assembled in a clean room. Take care to minimise any dust of you need to separate the front lens section.

Remove 3 silver 12mm Philips #2 screws joining the DMD optical section to the front lens. The three screws cannot be seen in one picture, so three pictures are attached.

The top screw is visible as you look down on the unit.

The left hand screw is seen as you look along the left hand underside of the DMD heat sink

The right hand screw is visible as you look along the right hand underside of the DMD heat sink.
