cable and contact your store of purchase.
Thermal Protector
When the temperature inside the projector becomes abnormally high, the STATUS indicator flashes red (0.5 seconds on/0.5
seconds off), the STANDBY indicator is a steady red, and at the same time the temperature protector operates and switches off
the power of the projector.
Should this happen, please take the following actions.
1. Switch off the power and disconnect the power plug from the wall outlet.
2. Check the following matters and take the required measures.
When the projector is being used in a location that has a high ambient temperature, set it up again in a cool location. Check the
outflow and intake holes and clean them if they are obstructed.
3. Wait about 60 minutes until the temperature of the projector drops.
If after having performed the above matters, the problem still has not been solved, please contact your store of purchase.

Troubleshooting
Check the following matters before requesting servicing.
•Is the power cord plugged into a power outlet?
•Is the lamp cover properly mounted?
•Is the projector’s temperature high? To protect the projector, the power can-
not be turned on when the projector’s temperature is abnormally high.
•Has the lamp reached the end of its service life?
•Depending on the timing with which the power cord is plugged in (the power
is turned on), it may happen that the STANDBY indicator (LED) does not
light and the power does not turn on. This is not a malfunction. If this hap-
pens, unplug the power cord then plug it back in.
•Is a connected input selected?
•Is the cable properly connected to the input terminal?
•When a computer is connected, are signals being output from the computer?
•Does the signal being input have a frequency usable with this projector?
•Are the brightness and contrast adjusted to the minimum?
•Is the STATUS indicator lit a steady red or flashing red?
•When the component signal of the DVD player is connected with the RGB
connector and the image is not output, is [Input Settings] of the RGB con-
nector properly selected?
•For a RGB input, has the picture been properly adjusted?
•Is the projector properly installed?
•For trapezoidal (keystone) distortion, perform keystone adjustment.
Please note that depending on the projected picture and the projection con-
ditions, it may not be possible to eliminate keystone distortion completely.
•Is the lens properly focused?
•Are the screen and projector installed at the proper distance?
•Does the projection distance exceed the focusing range?
•Is there condensation on the lens, etc.?
If the projector is moved from a cool storage area to a warm place and the
power is turned on, condensation may form on the lens or internal optical
par ts. If this happens, wait until the condensation has evaporated before
using the projector.
•For a computer input, are the horizontal and vertical positions properly ad-
justed?
•Does the input signal have a compatible resolution and frequency? Check
the computer’s resolution.
•If the image is crushed in the horizontal or vertical direction or if it is not
displayed over the entire screen, select a different aspect ratio.
•When a component signal is being input, is the color space setting proper?
•For a composite input, is the tint properly adjusted?
•From the menu, select “Image” and adjust the “Picture Adj.” and “Fine Picture”.
•Other than [Settings], [Option] and [Information], selection will not be pos-
sible unless a signal is being input to the projector and the image/picture is
projected.
•Are the remote control unit’s batteries worn? Replace with new batteries.
•Is there an obstacle between the remote control unit and the projector’s
remote control signal sensor?
•Is the remote control unit outside of range?
•Are you pointing the remote control unit’s transmitter towards the projector’s
remote control signal sensor?
•See “When an indicator is lit or flashing”. Power does not turn on

Cleaning
•Be certain to disconnect the power plug from the power outlet before cleaning.
•Do not spray or otherwise expose the projector, lens, or screen to volatile substances such as insecticides. Do not leave rubber
or vinyl products in contact with the projector for long periods. Doing so could cause them to undergo qualitative changes or the
coatings may peel, etc.
Cleaning a Soiled Projector Main Unit
•Wipe with a lint-free, soft, dry cloth.
When very dirty, wipe with a cloth that has been moistened with a diluted neutral detergent, then finish with a dry cloth. If a
chemically-treated cloth is going to be used, please follow any written warnings.
•Do not wipe with thinner, benzene, or other solvents. Doing so could cause them to undergo qualitative changes or the coatings
may peel, etc.
•When removing the dust of the outflow and intake holes, use the brush attachment on a vacuum cleaner to clean out the dust.
Avoid using the vacuum directly without attaching the adapter as well as the use of a nozzle adapter.
•Do not scratch or otherwise hit the projector body with your nails or other hard object, since this will cause scratches.
Dirty Lens
•Clean using the same method you would use to clean a camera lens: Use a commercial blower for camera use or cleaning
paper for eye glasses. Be careful not to scratch the lens at this time.
Dust of the Intake and Outflow Holes
Dust that collects in the intake and outflow holes will obstruct the ventilation and cause the internal temperature to rise which
could cause damage. Clean this area carefully. As a guideline, clean at least every 100 hours of usage.
•Switch off the power, check that the STANDBY indicator has
changed to a steadily lit amber, then unplug the power cable.
•Clean out the holes from the outside using a vacuum cleaner.
Use the brush adapter of the vacuum cleaner to do this. Avoid
using the vacuum directly without attaching the adapter as well
as the use of a nozzle adapter.
Cleaning the Inside of the Projector
Cleaning of the inside of the projector is required about once a year. Failure to clean over a long period while dust has collected
inside the projector could cause a fire or breakdown. Do not clean the inside of the projector by yourself. Please be sure to contact
your dealer.

Replacing the Lamp Cartridge
•The lamp that is used as a light source in the projector has a limited service life. The rated service life of the lamp is
about 2000 hours (when used in normal mode only). This could be shortened depending on conditions of use and
other factors.
Note that lamp life will be extended when the projector is often used in Eco mode. (The rated service life of the lamp
means the average value of lamp life for lamps that have been manufactured over a long period, and it is derived from
test conditions at this company.)
•When the life of the lamp is exceeded, the STATUS indicator lights a steady red and the message [Replace the Lamp
Cartridge] is displayed on the screen. When this occurs, it is time to replace the lamp cartridge. Please make the
replacement following the procedure below.
•If the projector is used another 100 hours after the lamp’s service life is reached, the power is set to the standby mode
and no longer turns on.
•Contact a store that sells the PX5 for a replacement lamp. Indicate you need a LKPX5 replacement lamp for the PX5.
CAUTION
• Replacement of the lamp cartridge is performed after switching off the power, waiting for the cooling fan to stop,
disconnecting the power plug from the power outlet, and then leaving the projector for about 60 minutes before
replacement is started. Replacement of the lamp cartridge during operation or immediately after operation stops will
cause burns because of the high temperature.
• Do not remove any screws other than those specified.
• Do not touch the lamp with bare hands. Doing so could shorten the life of the lamp.
• If lamp has reached the end of its usable life, the lamp bulb may shatter. When this happens, an explosive sound can
be heard and pieces of glass may be scattered in the lamp cartridge. Do not touch them as the pieces of glass may
cause injury. If this happens, contact your dealer or the store the projector was purchased.
