Troubleshooting
Check
• Projector power cord is not plugged into the wall outlet.
• Power to the external connected devices is off.
• The selected input mode is wrong.
• The AV MUTE function is working.
• Cables incorrectly connected to the rear panel of the projector.
• Remote control batteries have run out.
• External output has not been set when connecting notebook computer.
• The filter cover, lamp unit cover or lamp housing cover is not
installed correctly.
• If the connected DVI digital equipment is turned on before the
“DVI-D” input mode is selected on the projector, the image may
not be projected properly or may not be displayed at all. Ensure
that the appropriate input mode has been selected on the
projector before you turn on the connected equipment.
• Cables incorrectly connected to the rear panel of the projector.
• “Bright” is set to minimum position.
• Depending on the computer you are using, an image may not
be projected unless the signal output setting of the computer is
switched to the external output. Refer to the computer’s
operation manual for how to switch its signal output settings.
• Image adjustments are incorrectly set.
(Video, S-Video Input only)
• Video input system is incorrectly set.
(COMPUTER/COMPONENT 1, 2, DVI-D only)
• Input signal type (RGB/Component) is incorrectly set.
• Adjust the focus.
• The projection distance exceeds the focus range.
• There is fog on the lens. If the projector is carried from a cold
room into a warm room, or if it is suddenly heated,
condensation may form on the surface of the lens and the
image will become blurred. Please set up the projector at least
one hour before it is to be used. If condensation should form,
remove the power cord from the wall outlet and wait for it to
clear.
(Computer Input only)
• Perform “SIG-ADJ” Adjustments. (“Clock” Adjustment)
• Perform “SIG-ADJ” Adjustments. (“Phase” Adjustment)
• Noise may appear depending on the computer.
• Cables incorrectly connected to the rear panel of the projector.
• Volume is set to minimum.
• When the projector is connected to an external device and the
volume is set to minimum, the sound is not output even if you
turn up the volume of the external device.
• “Speaker” is set to “Off”.
• Make the necessary adjustments of each item in the “SIG-ADJ”
menu.
• Depending on the computer you are using, the output resolution
signal may be different from the one you have set. For details,
refer to the operation manual of the computer.
