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 28 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.

 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 22 to try

to solve the trouble.

• Have the COLOUR and BRIGHT settings

been adjusted properly? Follow the

description “Picture adjustment” on

page 20 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. There is

nothing wrong with the TV.
