Filter Maintenance and Light-Source Lamp Replacement
Note
• If the filter is clogged with dirt, etc., the projector goes into an
emergency mode (the EMERGENCY indicator blinks).
So, clean the filter periodically. For the emergency mode, refer to
pages 8 and 24.
1
Bring the projector into stand-by
state, and turn off the MAIN POWER
switch.
Put the projector into stand-by, and make sure the STAND
BY indicator is lit, then tun off the MAIN POWER switch.
After that, disconnect the power cord from the wall outlet
and the projector. For detailed procedures, refer to
“Turning off the power” (page 25).
2
Remove the filter cover screws.
Using a Phillips screwdriver, remove the six screws fixing
each filter.
Two filters are used, one on the right side and the other
on the back of the projector.
3
Remove the filters.
To remove the filter, pinch the center portion of the filter
with your fingers and pull it toward you.
(The filter is held by four tabs.)
There are two filters used.
Cleaning and Replacing the Filter
The filters should be cleaned periodically. If they are heavily stained, do not become clean if cleaned, or are damaged, replace
them with new filters (Parts number: LC30505); otherwise, dirt and dust may get inside, possibly causing an adverse effect on
the screen and preventing you from enjoying clear pictures.
■ The projector has two filters installed, one on the right side and the other on the back.
