The temperature is abnormally high.
• Refer to “About the Temperature Protector” below.
The fan has stopped.
Unplug the power cable and contact a store that sells the U7-
132/U7-137 for repairs.
The lamp will not light.
Wait at least 90 seconds, then turn the power back on. If the
problem persists, unplug the power cord and contact a store
that sells the U7-132/U7-137 for repairs.
Should an indicator be in a condition other than normal or flash at a rate other than the aforementioned, disconnect the power
cable and contact your store of purchase.
Thermal Protector
When the temperature inside the projector becomes abnormally high, the STATUS indicator blinks 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 blinking red?
• When the component signal of the DVD player is connected with the DVI or
RGB connector and the image is not output, is [Input Settings] of the DVI or
RGB connector properly selected?
•
For a analog RGB or DVI analog input, has the picture been properly adjusted?
• Is the projector properly installed?
• For trapezoidal (keystone) distortion, perform keystone adjustment.
• 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 inputting component signals (HDTV signals only), is “Color Space”
setting correct?
• For a composite input, is “Tint” properly adjusted?
• From the menu, select “Image” and adjust the “Picture Adj.” and “Fine Picture”.
• Other than [Setup], [Option] and [Info], selection will not be possible 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 blinking”. 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.
