PC Picture
If no PC picture appears, check that the D-
SUB cable is connected properly. Check that
your PC’s resolution set correctly. See
pages 43 for supported modes.
Sound
You can not hear any sound. Did you per-
haps interrupt the sound, pressing “ ” but-
ton? Are external speakers connected to the
TV?
Sound is coming from only one of the
speakers. Is the balance set to one direction
extreme? See Sound menu.
Remote Control
If your TV no longer responds to the remote
control, perhaps the batteries are ex-
hausted. Replace the batteries.
Have you selected the wrong menu? Press
“ MENU ” button to return to normal screen or
press “ BACK ” button to return to the previous
menu.
No solution
If the TV suddenly stops responding, discon-
nect the power cord of the TV from the AC
outlet. Connect themto the AC outlet again to
turn on the TV. If the TV returns to a normal
state, it is not a failure. If this does not work,
switch off, remove the mains plug and call
the service personnel; never attempt to re-
pair it yourself.
Bad picture (in digital mode)
Although this TV can receive both Digital ter-
restrial broadcasting (DVB-T) and Analogue
terrestrial broadcasting, you may not be able
to receive DVB-T depending on the area in
which you live.
If the picture freezes a lot, or block effect is
seen frequently on screen, probably there is
a problem with your reception.
Please contact customer services of your
service provider if you are a subscriber.
Tips
Can not turn the TV on?
Check that TV/VCR/DVD switch is set to TV
position.

the TV on soon after you turn the TV off. If you
can turn the TV on again, it is not a problem.
Can not turn the TV off?
Check that TV/VCR/DVD switch is set to TV
position.
Care of the Screen
Clean the screen with a slightly damp, soft
cloth. Do not use abrasive solvents as they
may damage the TV screen coating layer.
Colours of image on screen are
abnormal
Have you selected the correct TV system? Is
your TV set or house aerial located too close
to the loudspeakers, non-earthed audio
equipment or neon lights, etc. ?
Mountains or high buildings can cause
double pictures or ghost images. Some-
times you can improve the picture quality by
changing the direction of the aerial.
Is the picture or Teletext unrecognisable?
Check if you have entered the correct fre-
quency.
The picture quality may degrade when two
peripherals are connected to the TV at the
same time. In such a case, disconnect one
of the peripherals.
No Image on Display Screen
Is the aerial connected properly? Are the
plugs connected tightly to the aerial socket?
Is the aerial cable damaged? Are suitable
plugs used to connect the aerial? If you are
in doubt, consult your dealer.
No Image means that your TV is not receiv-
ing any transmission. Have you pressed the
correct buttons on the remote control? Try
once more.
