Solution
• Adjust the focus. (See page 19.)
• Clean the lens.
• Press the or button on the remote control to eliminate flicker.
• Adjust TRACKING and FINE SYNC. in the SIGNAL menu. (See page 30.)
• Set OVER SCAN in the SIGNAL menu to 100%. (See page 30.)
• Set the keystone adjustment to 0 using the KEYSTONE button. (See page 17.)
• Set the projected image size to maximum (0) in E-Zoom function.(See page 12.)
• Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 26.)
• Adjust the projector and the screen so that they are perpendicular to each other.
(See page 17.)
• This phenomenon is improved by keeping projecting an evenly bright image. (Such
"image burn-in" phenomenon where afterimages persist on the screen may occur if
a stationary image is kept displayed on the screen for a long time.)
• This phenomenon is normal for a DLP™ projector and is not a malfunction. (A very
small number of pixels may visibly or invisibly be persistent all the time, but they are
not a sign of system malfunctions. Over 99.99% of the pixels are effective.)
• This is due to interference with the screen surface and is not a malfunction. Replace
the screen or displace the focus a little.
• Vertical or horizontal streak noise may appear on the projected image, depending
on the type of the DVD player, game console or computer you use. In such a case,
you can reduce such streak noise by enabling the LPF.
• Connect the plugs of the cables to external devices securely.
• Keep the projector away from equipment generating interfering radio waves.
• When the keystone adjustment is carried out, the image may not be displayed
correctly because of the type of input signal. This isn't a product malfunction. In this
case, readjust the keystone so that the amount of keystone correction is as small as
possible.
• Check that the cables connected to the external devices are not broken.
• If the setting of COMPUTER INPUT in the SIGNAL menu is inconsistent with the
RGB/Y output setting of the external device even when the input source is
C C
B R
other than computer (for example, when the input source is HDMI), the entire image
appears reddish or greenish.
• Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 30.)
• Check that the cable connected to the external device isn't broken.
• When comparing images projected by two projectors, tints in the displayed images
may be different because of variation between their optical components. This is not
a malfunction.
• When comparing the image projected by this projector with those displayed on the
television or PC monitor, tints in the displayed images may be different because of
difference in the range of color reproducibility. This is not a malfunction.
• This is caused by the computer being used. Contact the manufacturer of your
computer.
