■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. (P59)
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. (P35, P151)
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. (P60)
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. (P143)
The tracking is bad. Adjust the tracking with the AUTO PC or Tracking function. 
(P57, P82)
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. (P87)
Using a VGA cable in which some 
pins are not connected. Use a supplied VGA cable (for SX800).
 If you use a commercial VGA cable, make sure to use a 
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, P49)
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. (P144)
The lamp has exploded (or it is 
defective).Check whether the lamp has exploded.
If the lamp has exploded, replace the lamp according to 
Lamp Handling Precautions on page 18. Check the lamp 
by replacing it with a spare lamp if you have one. (P18, 
P145, P146) 
						

							Troubleshooting142
■You cannot operate the remote control.
The operating temperature is inap-
propriate. Check whether the operating temperature is 5 to 35°C. (
P20)
If you use the projector at 1900 meters or higher above sea 
level, contact your dealer.
Other reasons The projector may be damaged. Contact your dealer.
Cause Countermeasure
Batteries are not installed properly 
or they have run out. Check whether batteries are in
stalled correctly. If batteries 
are installed correctly, replace them with new batteries. ( P31)
You are operating the remote con-
trol from the outside of the remote 
control operating range. Check whether you are operating the remote control within 
the remote control operating range. (
P31)
There is an obstacle between the 
projector and the remote control. Remove the obstacle between the infrared remote receiver 
of the projector and the remote control or point the remote 
control to an obstacle-free path.
You are operating the remote con-
trol under an inappropriate operat-
ing environment. Check whether the infrared remote receiver of the projector 
is exposed to direct sunlight or
 strong light of lighting appa-
ratus. ( P31)
The channel setting of the remote 
control does not match with the 
setting of the projector. Check whether the channel setting of the remote control has 
been changed. You can check the [Remote control] setting 
in the [System settings] menu. (
P107)
The key lock function is prohibiting 
the remote control operation. Check whether [Key lock] is enabled to disable the remote 
control operation.
In the System settings menu, set [Key lock] to [Off]. (

Maintenance
Cleaning the Projector
Clean the projector frequently to prevent dust from settling on the surface.
A dirty lens may ruin the quality of the projected image.
Wipe the projectors main unit softly with a soft cloth.
If the projector is heavily soiled, soak the cloth in water with a small amount of detergent 
in it, squeeze the cloth very well, and then wipe the projector with it. After cleaning, wipe 
the projector with a dry cloth.
 The main unit is very hot immediately after turning off the projector. Wait until the projector 
cools down sufficiently (more than 1 hour) before cleaning the projector. Otherwise, you may 
get burned or injured.
 Before cleaning the projector, be sure to remove the power plug from the AC outlet. Other-
wise, electric shock or fire may result.
 Never use volatile cleaning liquid or benzine, as these may damage the finish of the pro-
jector.
 When using a chemical dust cloth, make sure to read the instructions thoroughly.
 When cleaning the projectors lens, use a commonly available air blower or lens cleaning 
paper. The lens surface is easily damaged, so do not use a hard cloth or tissues.
Caution
When Not Used for an Extended Period of Time
Be sure to attach the lens cap on the lens and store in the supplied carrying bag.

Cleaning and Replacing the Air Filter
An air filter is installed in the air intake vent on the bottom of the main body to protect the 
internal lens and mirror from dust. Should the air filter become clogged with dust, the pro-
jector may be damaged since it will block the air flow into the projector and raises the 
internal temperature of the projector. The following screen is displayed when turning on 
the projector if the air filter needs to be cleaned. Clean the air filter if such is the case.
■Cleaning the Air Filter
 Turn the projector upside down, remove the cover by pushing the latch, remove the air 
filter, and clean it with a vacuum cleaner.
 When cleaning dust off the rear exhaust vent and bottom air intake vent, bring the vac-
uum cleaner nozzle close to them directly.
 If the above screen is displayed when turning on the projector after cleaning the air fil-
ter, select [Yes].
■Replacing the Air Filter
Make sure to replace the air filter when replacing the lamp.
Follow the following procedure when replacing the air filter.
1Turn off the projector, disconnect the 
power plug from the AC outlet, and let 
the projector stand for at least 1 hour.
2Remove the filter cover by pushing the 
position of the arrow.
3Remove the air filter.
4Install a cleaned or new air filter.
5Install the filter cover securely without 
any space.
 Only [], the OK button, and the POWER button 
are available while this screen is displayed (When 
you press the POWER button, Push POWER button 
again to turn off power. message appears).
 After this screen has been displayed for 10 seconds 
and disappeared, all buttons become operable.
 Handle the air filter carefully. If damaged, the air filter will not work appropriately
 An air filter can be ordered from your dealer.

When Projecting an Image from Image Software
To project an image such as an image shot by a TV set, commercially available DVD software, 
or video camcorder (input signal [HDMI (SX80 II)], [VIDEO], [S-VIDEO (SX80 II)], [COMPO-
NENT]), select an aspect ratio according to the image software format as follows.
*1[Auto] cannot be selected for the aspect setting if the input signal type is [VIDEO].*2If an image from image software with aspect ratio of 16:9 is not projected correctly, select [16:9] 
as screen aspect.
*3If you project the 16:9 image with black borders at top and bottom such as in the terrestrial movie 
broadcasting, you can project the 16:9 image fully on the screen by selecting [Zoom] in [Aspect].
[Zoom] is available when [16:9] or [16:9 D. image shift] is selected for the screen aspect and 
[HDMI (480p)(SX80 II)], [COMPONENT (480p, 480i)], [VIDEO] or [S-VIDEO (SX80 II)] is selected 
for the input signal.
