Remedy
If you use the lens shift function with a setting outside the
recommended range, edges of the image may be cut off or
appear dark. Use a setting within the normal range for the lens
shift function.
Warping is set.
Disable the warp correction feature.
The settings for "Brightness," "Contrast," and "Light Output
Mode" affect brightness of the image. Check if the value is
appropriate.
"With Static Signal" is set to "On."
When video signal is not input, the light is dimmed to reduce
power consumption.
When the temperature around the unit is high, the brightness
will be reduced to protect the unit.
Check if the projector is in focus.
The picture will not be clear if condensation has accumulated
on the lens. In such a case, let the projector sit for about two
hours with the power on.
Check if the connecting cable is connected to external
equipment properly.
Check that the connecting cables between the projector and
external video or audio equipment are securely connected.
Check if the output setting of connected external audio
equipment is set for output the audio signal from the projector.
Audio is not output if audio muting is activated.
Check if the "Audio Output Vol." is set to minimum.
Check that the batteries are installed correctly.
Check that the batteries are not exhausted.
Check if the "ID Mode" of the projector corresponds to that of
the Remote Commander.
Check the setting for "IR Receiver."
The sound from the fan is often greater than normal to cool the
light source in the following cases.
• When "Light Output Mode" is set to "Standard."
• The projector is in at high altitude ("High Altitude Mode" is
set to "On")
• Temperature is very high.
• Check that the air filter is clogged, then clean or replace it.
• Check that the ventilation holes (intake/exhaust) are not
blocked by a wall or an object and secure a sufficient gap.
