If a problem arises while you are using the TV, please read this troubleshooting guide carefully before you ask to have the TV
repaired. You may be able to fix it easily by yourself. For example, if the mains plug is disconnected from the mains outlet, or the
TV aerial has problems, you may think there is a problem with the TV itself.
Important:
•This troubleshooting guide only covers problems whose causes are not easy to decide. If you have a question when you are
operating a function, read the page(s) for that function carefully, not this troubleshooting guide.
•If you follow the advice in this troubleshooting guide without any success, unplug the mains plug and ask for your TV to be
repaired. Do not attempt to repair the TV by yourself or to remove the rear cover of the TV.

so, the BLUE BACK function will be activated: the entire

BACK” on page 22 to try to change the BLUE BACK function
setting to OFF.
•Have you connected headphones to the TV?

•If noise (snow) totally block out the picture, there may be a
problem with the aerial or aerial cable. Check the following
to try to solve the problem:
− Have the TV and aerial been connected properly?
− Has the aerial cable been damaged?
− Is the aerial pointing in the right direction?
− Is the aerial itself faulty?
•If the TV or aerial suffers interference from other equipment,
stripes or noise may appear in the picture. Move any
equipment sach as an amplifier, personal computer, or a
hair drier, that can cause interference away from your TV.
Or try moving the TV. If the aerial suffers interference from
a radio tower or high-voltage wire, please contact your local
dealer.
•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 18 to try to solve
the trouble.
•Have the COLOUR and BRIGHT settings been adjusted
properly? Follow the description “Picture adjustment” on
page 17 to try to adjust them properly.
•Videotaping teletext is not recommended because it may
not record correctly.
•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 is
coloured. This is 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.

•Have you adjusted BASS or TREBLE properly? If not, follow
the description “Sound adjustment” on page 19.
•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 19 to hear the sound
more easily by changing it to a mono sound.

•Have the batteries of the remote control worn out? Follow
the description “Putting batteries into the remote control” on
page 4 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 the 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 will not respond suddenly, press the main power
button on the TV and turn off the main power. Press the
main power button again to turn on the TV. If the TV returns
to a normal state, it is not a failure.

•When the SLEEP TIMER function operates, the TV is
automatically turned off. If the TV is turned off suddenly, 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 a WSS signal is included in the broadcast signal or
the signal from an external device, or when the TV is
receiving a control signal from an external device, the
ZOOM mode will change automatically. When you want to
return to the previous ZOOM mode, press the 5
55
5 button to
choose the ZOOM mode again.
•If you bring a magnetised device such as a speaker near to
your TV, the picture may be warped or unnatural colors now
appear at the corners of the screen. In this case, keep the
device away from your TV. If speakers cause this to happen,
use magnetic-shielded speakers instead.
•The TV may make a crackling sound due to a sudden
change in temperature. The picture or sound may be nomal.
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.
