You Cannot Project An Image Appropriately; The Projector Power Turns Off - Canon WUX450 User Manual

■ 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 higher than 162
MHz with a BNC cable.
A computer 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.
The lamp has broken
(or there is a lamp
malfunction).
The operating
temperature is
inappropriate.
Countermeasure
The ceiling mounted / rear projection setting is
incorrect. Check the [Image flip H/V] setting in the
[Install settings] menu. (P143)
Set the signal dot clock to 162 MHz or less on your
computer.
Use a computer 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 automatically turned off to protect the
projector. (The [WARNING] indicator and [TEMP]
indicator are lit.) Wait until the projector temperature
drops, then make sure that the intake and exhaust
vents are not blocked and turn on the projector. (P36,
P50)
Check whether the air filter is clogged with dust.
If the air filter is clogged, clean or replace the air filter.
(P195)
Check whether the lamp has broken.
If the lamp has broken, follow the instructions on
page 26. If the lamp has not broken, there may be a
malfunction with the lamp. Check the lamp by
replacing it with a spare lamp if you have one. (P27,
P197, P198)
Check whether the operating temperature is between
0°C and 40°C. (P29)
If you use the projector at 2,300 m (7,545.8') or
higher above sea level, contact the Canon Customer
Support Center.
