The Projected Image Is Blurred; You Cannot Project An Image Appropriately; The Projector Power Turns Off - Canon REALiS WUX4000 User Manual

■The Projected Image Is Blurred

Cause
The image is out of focus.
The distance to the screen is too
short.
The projector is not placed
straight in front of the screen.
The projector has been moved to
a place where the temperature
varies a lot.
The lens is stained.
The tracking is bad.

■You Cannot Project an Image Appropriately

Cause
The projected image is inverted in
the vertical or horizontal direction.
The dot clock of the input signal is
162 MHz or higher with a BNC
cable.
A VGA cable is used in which
some pins are not connected.

■The Projector Power Turns Off

Cause
The air intake or exhaust vent is
blocked.
The air filter is dirty.
Countermeasure
Adjust the focus. (P59)
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. (P125)
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. (P62)
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.
Clean the lens. (P158)
Adjust the tracking with the [AUTO PC] or [Tracking] func-
tion. (P51, P79)
Countermeasure
The ceiling mounted / rear projection setting is incorrect.
Check the [Image flip H/V] setting in the [Display settings]
menu. (P85)
Set the signal dot clock to 162 MHz on your computer.
Use a VGA cable in which all pins are connected.
Countermeasure
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.
(P27, P45)
Check whether the air filter is clogged with dust.
If the air filter is clogged, clean or replace the air filter.
