7. Carefully, remove the lens mount from the front of the projector and at the same
time, feed the lens mount harnesses through the bottom left corner of the lens
mount.
When replacing the lens mount, perform steps in reverse. It is important to route
the harnesses back through the opening in the bottom left corner of the lens mount.
If installing a new lens mount, Lens Bore-sight Alignment will be required. Refer
to the separate instruction sheet provided in the Lens Mount service kit.
Light Engine
(42 minutes)
The light engine is on the right hand side of the projector, behind the lens mount. It
is mounted to the optical mount. To safely remove the light engine, the entire
optical assembly (optical mount and light engine) must first be removed and then
separated.
1. Remove the top cover. See Top Cover for instructions.
2. Remove the TIPM card cage. See Card Cage (TIPM).
3. Remove the black exhaust duct secured to the light shield (three screws). See
Figure 19.
4. Disconnect the cables from the TCPD/HDPD. Then route the blue DMD
flex/LVDS cable through the small bracket on the board.
IMPORTANT – Do not pull on the flex cables when disconnecting to prevent
damage. Unlock the flex cable connector first (flip tab down) before removing
the cable. See Flex/LVDS Cables.
5. Disconnect the shutter, DMD fans (not on 500W models), DMD power cables,
the LiteLOC sensor and the contrast aperture from the Panel Driver PCB.
(Figure 23.)
6. Remove the lens dust cover (also called the lens bezel), by removing seven (7)
screws accessible from the inside and the two (2) screws located on the bottom
cover. (Figure 52.)
7. Disconnect all the lens cable connections from the front edge of the
TCPD/HDPD (Figure 53.) Unclip them from the wire clip so they are free to
remove when the optical assembly is removed in the next step.
8. Remove the optical assembly (includes optical mount and light engine) from
the projector by removing the following five (5) screws (Figure 55.):
• Two (2) screws located on the fold mirror side (#1 & 2)
• One (1) screw located behind the red DMD (#4)
NOTE: Requires a long screwdriver to access.
• One (1) screw located on the side closest to the lamp compartment (#3)
• One (1) screw securing the optical mount to the TCPD/HDPD mounting
frame (#5)
Lift the optical assembly out of the projector and set it aside in a clean area for
further disassembly.
