Remove and Replace the Top Case
The top case (505-1508-xx) covers the top half of the half of the projector. Once you remove the top
case, you have access to FRUs inside the projector. When you replace the top case, you need to adhere
a new nameplate (020-1118-xx) to the top case.
1. Remove the following items:
Lamp module (see page 42)
Focus ring (see page 30)
Zoom ring (see page 30)
Front bezel (see page 32)
Rear bezel (see page 49)
2. Place the projector upside down on a soft work surface. Remove the four M4x18 Plastite Phillips
screws from the bottom case.
3. Holding the top case against the bottom case, turn the projector over and place it right side up on
the work surface.
