Troubleshooting

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.
If you cannot turn on the TV
• Are the mains plugs on the power cords from the TV and
receiver connected to mains outlets?
No picture or no sound
• Have you chosen a TV channel with very poor
reception? If so, the BLUE BACK function will be
activated: the entire screen becomes blue, and the sound
is muted. If you still want to view the TV channel,
follow the description "BLUE BACK" on page 33 to
change the BLUE BACK function setting to OFF.
• Have you set the SPEAKER function to OFF? Follow
the description "SPEAKER" on page 29 to check the
SPEAKER function setting.
Poor picture
• If noise (snow) totally blocks 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 such 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 27 to try
to solve the trouble.
• Have the COLOUR and BRIGHT settings been adjusted
properly? Follow the description "Picture Adjustment"
on page 25 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.

Poor sound
• Have you adjusted BASS or TREBLE properly? If not,
follow the description "Sound Adjustment" on page 29.
• 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 29 to hear the
sound more easily by changing it to a mono sound.
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 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 b button to return to the
ordinary TV programme, and then try operating the
menus.
• If the TV suddenly stops responding, disconnect the
power cords of the TV and receiver from the AC outlets.
Connect them to the AC outlets again to turn on the TV.
If the TV returns to a normal state, it is not a failure.
