Some pixels on the screen
do not light up.
●
LCD panels are made with very high precision technology. However, there
may be missing pixels or bright spots in some parts of the screen, but this is
not a malfunction.
-
Power supply doesn’t
start.
●
Check if the power supply plug or the connector is removed from the power
socket or the device.
20
Power automatically turns
off unexpectedly.
●
Check the settings of [Sleep Timer], [Power Management Setting] and [No
Activity Power Off]. Any of them may be set to [On (Enable)].
27
Power indicator is blinding
in red
●
There is a possibility of malfunction. Please contact your dealer.
-
No remote control
operations can be
performed.
●
Check whether the batteries have discharged completely and, if they have
not, whether they were inserted properly.
-
●
Check whether the remote control sensor is exposed to an outdoor light or a
strong fluorescent light.
-
●
Check whether any obstacle is present between the remote control sensor
and the remote control.
If the installation condition is normal, pull out the remote control sensor from
the edge side of the main unit when using.
19
●
Check whether the remote control designed specifically for use with the unit
is being used. (The unit cannot be operated by any other remote control.)
-
●
Check if [Initial Setting] - [Remote Operation] is set to [Disable].
45
It takes a while for the
picture to appear.
●
The unit digitally processes the various signals in order to reproduce
esthetically pleasing images. As such, it sometimes takes a few moments
for the picture to appear when the power has been turned on, or when the
input has been switched.
-
Spots appear on the
screen.
●
This may occur because of interference from automobiles, trains, high
voltage lines, neon lights, etc.
-
Colour is pale.
●
Check if the colour strength is adjusted properly. (Check the adjusted values
of the picture.)
41
Coloured pattern appears
and then the colour fades.
●
Check if the unit is affected (interference) by another imaging device.
This symptom may improve if the installation location of the unit is changed.
-
The top or bottom of the
picture on the screen is
cut off.
●
The image position has been adjusted.
Adjust the position of the picture on the screen.
42
There are areas at the
top and bottom of the
screen where picture is not
displayed.
●
When using a video software programme (such as a cinema size
programme) with a screen wider than one in the 16:9 mode, blank areas
separate from the images are formed at the top and bottom of the screen.
-
The edges of the images
flicker.
●
Due to the characteristics of the system used to drive the liquid crystal
panel, the edges may appear to flicker in the fast-moving parts of the
images. This is normal and not indicative of malfunctioning.
-
The unit cannot be
operated with the buttons
provided in the unit.
●
Check if [Keypad Operation] is set to [Disable].
45
There is no picture
displayed or sound output
sometimes.
●
When HDMI or DVI signals are input to the display using a selector or
distributor, sound or images may not be output in the normal fashion
depending on the selector or distributor used.
The symptoms may be improved by turning the power off and on again, or
by replacing the selector or distributor.
-
Display is strange such as
no picture, or the remote
control stopped working
suddenly.
●
Very advanced software is embedded in the unit. If you feel something
is strange, for example “The remote control cannot be operated” or “The
display is corrupted”, remove the power supply plug from the power socket
and insert the power supply plug once again after about 5 seconds and start
the power supply.
26
Serial control doesn’t
work.
●
Check if the connection is correct.
