with the technical specifications of the projector, and in
particular, with the specifications of the selected input.

• Check compatibility of the video or graphic signals
with the technical specifications of the system, and in
particular, with the specifications of the selected input.
• Adjust Y/C DELAY settings in the IMAGE menu to reduce
colour misalignment.
REMOTE CONTROL DOES NOT WORK
• Check remote control battery power and that they are
inserted correctly.
• Ensure the area between the infrared sensors (on the
front panel of the projector) and the remote control is
free from obstructions.
• Make sure the infrared sensors on the front and rear
of the projector are not exposed to very bright light
levels.

safety norms included in the bracket packaging.
12 OPTIONAL ACCESSORIES
• Check the state of the connection by interpreting the
code displayed by the projector LEDs.
• Make sure the cooling air vents on the units are not
blocked and that the room temperature is below
35°C.
IMAGE IS DISTURBED, UNSTABLE OR NOISY
• Check compatibility of the video or graphic signals with
the technical specifications of the projector, and specifi-
cally, with the specifications of the selected input.
• Check all cables.
• If the problem occurs on a terrestrial broadcast source
signal, check that the receiver has been correctly tuned
in and that the aerial system is in good working order.
• Adjust the Sharpness parameter in the PICTURE menu
to optimise the projected image.
• If you are using a Blue-Ray or HDVD high-definition disk
player, consider that the material recorded on the disk
may be coded with a frame rate of 1080p 24Hz, which
is the same format shown at the movies. Often the film
previews, screen notices, menus and special sections
are recorded at a different frequency than the main
section, such as 1080i 25/30Hz, etc.
• For this reason, depending on how the player is set, the
projector will appear to be “searching” for the correct
signal and sometimes it will display “No signal” while
the player is synchronizing on the correct format. On
these occasions, a few seconds of the beginning of the
program may not be displayed while the projector is
stabilizing. This is normal and should not be considered
as a malfunction.
INCOMPLETE IMAGE AT EDGES
• Check compatibility of the video or graphic signals
with the technical specifications of the projector, and in
particular, with the specifications of the selected input.
• Open the automatic image adjustment function by
pressing the key A on the remote control or ◀ on the
projector’s keypad.
• Adjust the horizontal or vertical position of the image with
the IMAGE/POSITION menu (if available for the input in
question).
• Adjust the image width and height, selecting Aspect in
the IMAGE /ASPECT menu.
• Adjust the overscan setting applied to the image on the
IMAGE/OVERSCAN menu.
IMAGE TOO DARK/PALE OR UNNATURALLY COL-
OURED
• Check compatibility of the video or graphic signals
with the technical specifications of the projector, and in
particular, with the specifications of the selected input.
• Adjust the CONTRAST, BRIGHTNESS, COLOUR and
TINT parameters in the PICTURE menu.

GAMMA CORRECTION (IMAGE menu).
