Troubleshooting
AV-32/28EX5BK / LCT1821-001A-U / ENGLISH
If the TV suffers interference from signals
reflecting from mountains or buildings,
double-pictures (ghosting) will occur. Try
to change the aerial’s direction or replace
it with one with better directionality.
Are your COLOUR SYSTEM settings
correct? Follow the description
“COLOUR SYSTEM” on page 39 to try
to solve the trouble.
Have the COLOUR and BRIGHT settings
been adjusted properly? Follow the
description “Picture Adjustment” on
page 37 to try to adjust them properly.
Videotaping teletext is not recommended
because it may not record correctly.
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.
When a white and bright still image (such
as a white dress) is displayed on the
screen, the white part may look as if it
were coloured. It is a phenomenon
unavoidable due to the nature of the
picture tube itself, and not due to a TV
failure. When the picture disappears from
the screen, the unnatural colours will also
disappear.
Poor sound
Have you adjusted BASS or TREBLE
properly? If not, follow the description
“Sound Adjustment” on page 41.
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 TV/DTV button to
return to the ordinary TV programme, and
then try operating the menus.
If the TV suddenly stops responding,
disconnect the power cord of the TV from
the AC outlet. Connect them to the AC
outlet again to turn on the TV. If the TV
returns to a normal state, it is not a failure.
Other issues
When the SLEEP TIMER 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.
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 stabilise
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.
If you bring a magnetised device such as a
speaker near to your TV, a picture may be
warped or unnatural colours appear at the
corners of the screen. In this case, keep
the device apart from your TV. If the
speakers causes such phenomena, use the
magnetic-shielded speakers instead.
