Troubleshooting ■The projected image is blur. 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. Countermeasure Adjust the focus. (P54) 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. (P33, P131) Check whether the projector is placed obliquely to the screen. A slight error in the projection angle can be corrected through the keystone adjustment function. (P55) 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. Clean up the lens. (P123) Adjust the tracking with the [AUTO PC] or [Tracking] function. (P52, P78) ■You cannot project an image appropriately. Cause The projected image is inverted in the vertical or horizontal direction. The dot clock of the inputted signal is 170MHz or higher with a BNC cable. Using a VGA cable in which some pins are not connected. Countermeasure The ceiling mounted/rear projection setting is incorrect. Check the [Image flip H/V] setting in the [Display settings] menu. (P83) Set the signal dot clock to 170MHz on your computer. Use a VGA cable in which all pins are connected. ■The projector is forced to be turned off. Cause The air intake or exhaust vent is blocked. The air filter is dirty. 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 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. (P24, P25, P44) Check whether the bottom air filter is clogged with dust. If the air filter is clogged, clean or replace the air filter. (P124) Appendix 121

Troubleshooting
Appendix
■
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. (
P54
)
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. (
P33
,
P131
)
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. (
P55
)
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. (
P123
)
The tracking is bad.
Adjust the tracking with the [AUTO PC] or [Tracking] func-
tion. (
P52
,
P78
)
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. (
P83
)
The dot clock of the inputted sig-
nal is 170MHz or higher with a
BNC cable.
Set the signal dot clock to 170MHz on your computer.
Using a VGA cable 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 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. (
P24
,
P25
,
P44
)
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. (
P124
)
