Remedy
The on-screen display does not appear when
"Status" in the Operation menu is set to "Off."
The image may not display correctly because the
input signal cannot be judged correctly. In this case,
set "Aspect" manually.
The images become trapezoidal because of the
projection angle. In this case, you can correct the
trapezoidal distortion, using a Keystone feature.
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 this case, let the
projector sit for about two hours with the power on.
Check if the connecting cable is connected to the
external equipment properly.
Check that the connecting cables between the
projector and external video or audio equipment are
securely connected.
Check if the external audio equipment is set
