• No sound comes from the TV speakers when the headphones are connected.
TV output from the EXT-1 terminal
The video/sound signal of a TV channel you are viewing is always output from the EXT-1 terminal.
• Changing over a Programme number (Pr.) also changes over the TV output from the EXT-1 terminal.
• Teletext programmes cannot be output.
TV and video output from the EXT-

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 button on the TV.
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 26 to change the Blue Back function setting to Off.
• If the Sound System setting for a TV channel is incorrect, it may prevent the sound from being issued. Follow the description “Manual Program” on page 22 to use the Manual Program function to try to change the Sound System 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
32
moving the TV. If the aerial suffers interference from a radio tower or high­voltage 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 25 to try to solve the trouble.
• Have the Colour and Bright-1 settings been adjusted properly? Follow the description “Colour” and “Bright-1” on page 19 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 “Bass” or “Treble” on page 21.
• When TV channel reception is poor, it can be hard to hear stereo or bilingual sound. In this case, follow the description “Sound Mode” on page 21 to hear the sound more easily by changing it to a mono sound.
Troubleshooting
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 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 (Text) button to return to the ordinary TV programme, and then try operating the menus.
• If the TV suddenly stops responding, disconnect the power cord of the TV from the AC outlet. Connect them to the AC outlet again to turn on the TV. If the TV returns to a normal state, it is not a failure.
Other issues
• When the Sleep Timer function operates, the TV is automatically turned off. If the TV suddenly turns off, try to press the
(standby) button to turn on the TV once again. If the TV goes back to normal, there is no problem.
• It takes a short period of time from the time an operation such as changing channels is performed until an image is displayed. This is not a fault. This is the time needed for the image to stabilize before it can be displayed.
• The TV may make a crackling sound due to a sudden change in temperature. The picture or sound may be normal. 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.
• The top of the TV and the screen may become hot during use but this has no affect on the performance of the TV. Make sure that the ventilation holes are not blocked.
• When the picture is unstable, the screen may become white for a moment. This happens when the signal which drives the liquid crystal is missing. This is not a fault.
• When a still image has been displayed for a long period, a faint residual image may remain on the screen for a short time after the power has been turned off or when another image is displayed. This is not a fault and the image will eventually disappear.
