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.

the Controller and the Projector.

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

screen’ or an otherwise scrambled
image.
· A progressive scan DVD is plugged
into Component input rather than the
RGB/Component input.

is a loss of denition in the brightest
areas of the image.
