■The Projected Image Is Blurred
■You Cannot Project an Image Appropriately
■The Projector Power Turns Off
Cause Countermeasure
The image is out of focus. Adjust the focus. (P73)
The distance to the screen is too
short.
Check whether the distance to the screen is appropriate. If
the distance is shorter than approximately 1.3 m (4.3'), the
projector cannot focus on the screen. (P156)
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. (P76)
The projector has been moved to
a place where the temperature
varies a lot.
When the projector is moved from a location where the tem-
perature is low to a location where the temperature is high,
condensation may form on the lens. The condensation will
evaporate after a period of time and the projector will be
able to project a normal image.
The lens is stained. Clean the lens. (P192)
The tracking is bad. Adjust the tracking with the [AUTO PC] or [Tracking] func-
tion. (P62, P96)
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. (P104)
The dot clock of the input signal is
higher than 162 MHz with a BNC
cable.
Set the signal dot clock to 162 MHz or less on your com-
puter.
A VGA cable is used in which
some pins are not connected.
Use a VGA cable in which all pins are connected.
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 will increase and the power is automati-
cally turned off to protect the projector. (The [WARNING]
indicator and [TEMP] indicator are lit.) Wait until the projec-
tor temperature drops, then make sure that the intake and
exhaust vents are not blocked and turn on the projector.
(P32, P56)
The air filter is dirty. Check whether the air filter is clogged with dust.
If the air filter is clogged, clean or replace the air filter.
