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
• Is the mains plug connected to the mains outlet?
• Is the power lamp lit? If not, press the main power
button.
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 20 to try
to change the BLUE BACK function setting to OFF.
• Have you connected headphones to the TV?
Connecting headphones to the TV turns off the TV
speakers.
• If the SYSTEM setting for a TV channel is incorrect, it
may prevent the sound from being issued. Follow the
description "EDIT/MANUAL" on page 23 to use the
MANUAL function to try to change the SYSTEM
setting.
Poor picture
• 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 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 17 to try
to solve the trouble.
• Have the COLOUR and BRIGHT settings been adjusted
properly? Follow the description "Picture Adjustment"
on page 16 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.

• 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, and not because of malfunction.
Poor sound
• Have you adjusted BASS or TREBLE properly? If not,
follow the description "Sound Adjustment" on page 18.
• 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 18 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 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 want to change the volume of the
headphones, follow the description "HEADPHONE" on
page 18.
• 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 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.
