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
•If the TV suffers interference from signals reflecting from mountains or buildings,
•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 bbutton 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.
