PROBLEM POSSIBLE CAUSE SOLUTION
The Projector does not turn on after
initial installation. The Power LED on
the front of the Controller stays red
after the power button is pressed.
· The DVI cable is not connected
between the Controller and Projector,
or is connected improperly.
· The projector is not plugged in, or
its AC outlet is not active. Look at its
power LED and see if it is illuminated.
· Ensure it is firmly plugged into both
the Controller and the Projector.
· Verify that the AC outlet is active, or
that the Projector is plugged in.
The Projector and Controller are both
on, but there is no video image on-
screen. · The Controller is on the wrong source.
· The Controller is on the correct
source, but the source itself is off.
· Press MENU on the Projector’s
remote, and look to see which source is
active (the arrow will be pointing to the
active source). Select the correct source
as appropriate.
· Turn on the source. It is recommended
that all sources be turned on first
BEFORE the VX-2c.
The Projector is producing a ‘split
screen’ or an otherwise scrambled
image.
· A progressive scan DVD is plugged
into Component input rather than the
RGB/Component input.
· Only NTSC/PAL can be input to the
Component input. Progressive scan
must go into RGB/Component.
The image appears too bright, and there
is a loss of definition in the brightest
areas of the image.
· Contrast is set too high.
· The DVD player is set for a high-level
output.
· The video signal has not been
terminated properly somewhere in the
system.
· Turn down the CONTRAST level on
the Controller.
· Set the DVD player for a nominal
output (no boost or gain).
· Ensure all video signals are
terminated in 75 Ohms.
The image appears too ‘washed out’, or
the darkest areas of the image appear
too bright. · Brightness is set too high.
· The DVD player may be set for too
high of a brightness level. · Turn down the BRIGHTNESS level
on the Controller. If possible, use a
PLUGE pattern to set the brightness
level properly.
· Set the DVD player for a nominal
output (no boost or gain).
The colors of the image appear
abnormal · The Red, Green and/or Blue outputs
of the Controller or inputs to the
Projector are reversed.
· The Pr and Pb inputs on the
Component input on the Controller are
reversed · Check the cable connections on
the back of the Controller or on the
Projector.
The Projector will not turn back on
after it was powered-down, or the
image disappears during operation. · The Projector will not turn on for two
minutes after power-down to protect its
bulb.
· The bulb has failed · Wait two minutes until the LED on the
front of the Controller turns red.
