■
The projected image is blur.
■
You cannot project an image appropriately.
■
The projector is forced to be turned off.
Cause
Countermeasure
The image is out of focus.
Adjust the focus. (
)
The distance to the screen is too
short.
Check whether the distance to the screen is appropriate. If
the distance is shorter than approximately 1.2m (3.9'), the
projector cannot focus on the screen. (
The projector is not placed straight
in front of the screen.
Check whether the projector is placed obliquely to the
screen. A slight error in the projection angle can be cor-
rected through the keystone adjustment function. (
The projector has been moved to a
place where the temperature var-
ies a lot.
When the projector is moved from a low-temperature place
to a high-temperature place, condensation may form on the
lens. The condensation will evaporate a while later and the
projector will be able to project a normal image.
The lens is stained.
Clean up the lens. (

Cause
Countermeasure
The projected image is inverted in
the vertical or horizontal direction.
The ceiling mounted/rear projection setting is incorrect.
Check the [Image flip H/V] setting in the [Display settings]
menu. (
Cause
Countermeasure
The air intake or exhaust vent is
blocked.
Check whether the air intake or exhaust vent is blocked. If the
air intake or exhaust vent is blocked, the temperature inside
the projector rises and the power is automatically turned off
to protect the projector. (The WARNING lamp flashes once.)
Wait until the internal temperature gets down, and then turn
on the projector without blocking the intake and exhaust
vents. (

)
The air filter is dirty.
Check whether the bottom air filter is clogged with dust.
If the air filter is clogged, clean or replace the air filter. (
)
The lamp has exploded (or it is
defective).
Check whether the lamp has exploded.
If the lamp has exploded, replace it. The lamp may be
defective if it has not exploded. Check the lamp by replacing
it with a spare lamp if you have one. (
The operating temperature is inap-
propriate.
Check whether the operating temperature is 5 to 35°C. (
)
If you use the projector at 2300 meters or higher above sea
level, contact your dealer.
Other reasons
The projector may be damaged. Contact your dealer.
