MESSAGES
The following messages may appear on your screen:
No signal:
The system does not recognise any signal applied to the
selected input. In this case:
• Make sure the selected input is connected to a video
or graphic signal and that that source is functioning
correctly.
• Check the condition of the cables used to connect the
system to the various sources.
• Make sure the video or graphic signals supplied by the
source are compatible with the system’s technical speci-
fications and, in particular, with those of the selected
input.
Out of range
This message appears when either the resolution or the verti-
cal/horizontal frequency of the input signal exceeds system
specifications (e.g. a QXGA graphic signal).
NO POWER (LEDs AL
WAYS OFF)
• Check that the projector’s power switches are turned
on.
• Check that the power cables are correctly connected
to the projector’s power sockets.
• Check the condition of the fuse located next to the power
socket at the rear of the projector.
• Replace the fuse located on the projector’s power socket
with an identical type (T 3,15A H).
• If the fuse blows repeatedly, seek technical assistance
from your nearest service centre.
LAMP FAILS TO SWITCH ON
•
If this happens immediately after the last time the unit
was switched off, allow a few minutes between switching
off and switching on again.
This will allow the lamp to cool down to the optimum
temperature for switching on.
• If the lamp fails to light - even though the unit has had
time to cool down - seek technical assistance from your
nearest service centre.
• Check the state of the connection by using Table 1 to
interpret the code displayed by the system LEDs.
• Reset the Projector & HOST by turning off
the power
on both units. Wait 10 seconds before powering on
again.
• Check fibre Optic cable connections on Projector and
Host.
NO IMAGE
• Make sure the selected input is connected to a video
or graphic signal and that that source is functioning
correctly.
• Check that the source is HDCP compliant, you will not
get a picture using encrypted material via the DVI-D
input.
• Make sure the video or graphic signals supplied by
the source are compatible with the C3X Lumis HOST
system’s technical specifications and, in particular, with
those of the selected input.
• Check the condition of the cables used to connect the
projector to its input sources.
• Check the state of the connection by interpreting the
code displayed by the system LEDs.
•
Make sure the cooling air vents on the units are not
blocked and that the room temperature is below 35°C.
PICTURE OK ON 1080i & 720P MATERIAL BUT NO
PICTURE DISPLAYED IN 1080P 60HZ/50HZ?
• This usually means that the HDMI cable has insufficient
bandwidth to pass 1080p 60hz/50hz.This is quite com
-
monon cheap cables and also excessively long cables.
We suggest using better quality cables and as short as
possible, avoid cables in excess of 10mtrs.
The HOST system do not require internal adjustments and
do not contain any user-serviceable parts.
To change the lamp, or for any repairs, always contact your
nearest technical service centre that will resolve all your
problems in a courteous and efficient manner.
To clean the outer cover of the projector use a soft cloth and
moisten slightly if necessary with water and a small amount
of neutral soap. Do not rub hard on the printed captions on
the rear panel.
The lens may be cleaned with a very soft, non-abrasive small
brush, in order to remove dust particles. Alternatively, use
a soft dry cleaning cloth (of the type used for camera lens
cleaning) to remove fingerprints and grease marks.
