ENGLISH
• When viewing images from commercially
available video software products, or
videos from videotapes which have been
recorded improperly, the top of the image
may be distorted. This is due to the
condition of the video signal. There is
nothing wrong with the TV.
• Since this TV is designed to make full use
of the resolution of the original video
source, the motion may appear unnatural
when the video source is input with 576p
progressive-scanning component signals.
If this occurs, change the output setting of
the connected device to 576i interlace-
scanning component signal output. See
the instructions that came with the device
for more information.
Poor sound
• Have you adjusted BASS or TREBLE
properly? If not, follow the description
“BASS” or “TREBLE” on page 34.
• When TV channel reception is poor, it can
be hard to hear stereo or bilingual sound.
In this case, follow the description
“STEREO / I • II” on page 34 to hear the
sound more easily by changing it to a
mono sound.
• If you cannot hear the normal sound even
if the picture of the TV channel appears
normally. Follow the description “EDIT/
MANUAL” on page 39 to use the
MANUAL function to change the
SYSTEM setting.
If the TV does not respond to the
remote control
• Have the batteries of the remote control
worn out? Follow the description “Putting
the batteries into the remote control” on
page 7 and replace them with new batteries.
• Have you attempted to use the remote
control from the sides or rear of the TV or
from more than seven metres away from the
TV? Use the remote control in front of your
TV or from less than seven metres away.
• When you are viewing a teletext
programme, you cannot operate the
menus. Press the 4 button to
return to the ordinary TV programme, and
then try operating the menus.
• If the TV suddenly stops responding,
press the A button on the receiver and
turn off the TV. Press the A button again
to turn on the TV. If the TV returns to a
normal state, it is not a failure.
Other issues
• If the CHILD LOCK function set to ON,
you cannot operate the TV with the front
control buttons of the TV. Set the CHILD
LOCK function to OFF.
• When the SLEEP TIMER function or
AUTO SHUTOFF function operates, the
TV is automatically turned off. If the TV
suddenly turns off, try to press the #
(standby) button to turn on the TV once
again. If the TV goes back to normal,
there is no problem.
• When the TV is receiving a wide-screen
signal (WSS) or a signal from an external
device affecting the screen size, the
ZOOM mode automatically changes.
When you want to resume the previous
ZOOM mode, press the c button
again.
• If you bring magnetised equipment such
as a speaker near to your TV, the picture
may be warped or unnatural colours may
appear at the corners of the screen. In this
case, keep the equipment away from your
TV. If speakers cause this to happen, use
magnetically-shielded speakers instead.
• It takes a short period of time from the
time an operation such as changing
channels is performed until an image is
displayed. This is not a fault. This is the
time needed for the image to stabilize
before it can be displayed.
• The TV may make a crackling sound due
to a sudden change in temperature. The
picture or sound may be normal. If you
hear crackling sounds frequently while
you are viewing the TV, there may be
other causes. As a precaution, ask your
service technician to inspect it.
• Touching the screen may cause you to
feel a slight electric shock due to its static
electricity. This is unavoidable due to the
construction of the picture tube. It is not a
problem with the TV. You can rest
assured that this static discharge is not
harmful.
