58 Solving Problems
■ Make sure the input signal matches the connected source. Check
the settings for the
Video Signal, Input A, and Input B options
in the Advanced menu. If the
Input B option is set to RGB when
the projector is receiving component video signals, the images
may look too green. If the
Input B option is set to YCbCr or
YpbPr when a computer is connected, the images may look too
purple. (See page 33 for more information.)
■ If the input source is a computer, check its display settings to
correct the color balance.
■ If the lamp is running out, the image will become darker. You
may need to replace the lamp.
Solving Problems with the Remote
Control
The projector doesn’t respond to remote control commands.
■ Make sure you are within 30 feet (9 meters) of the projector, and
within range of the projector’s front or back sensor
(approximately 30° to the left or right and 15° above or below).
■ The remote control batteries may not be installed correctly or may
be low on power. Try replacing the batteries.
■ Dim the room lights and turn off any fluorescent lights. Make
sure the projector is not in direct sunlight. Strong lighting,
especially fluorescent lights, may affect the projector’s infrared
receivers.
■ Turn off any nearby equipment that emits infrared energy, such
as a radiant room heater.
