TROUBLESHOOTING

If a problem arises while you are using the TV, please read this “Troubleshooting” well before you request having the TV repaired. You may be able to fix it easily by yourself. For example, if the AC plug is disconnected from the AC 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 cause are not easy to determine. If a question arise when you are operating a function, read the page(s) corresponding to the operation of the function well, not this Troubleshooting guide.

After you have followed the Troubleshooting description or the operating description of the functions concerned without any suc- cess, remove the AC plug from the AC outlet and request a repair of your TV. Do not attempt to repair the TV by yourself or remove the rear cover of the TV.

If you cannot turn on the TV

Is the AC plug connected to the AC outlet?

Is the Power lamp lit? If not, press the Main power button.

No picture/No sound

Have you chosen a TV channel whose reception is extreme- ly bad? In this case, the BLUE BACK function will be activat- ed, the entire screen becomes blue, and the sound is muted. In spite of this, if you want to view the TV channel, follow the description “BLUE BACK” on page 21 to try to change the BLUE BACK function setting to OFF.

Have you connected the headphones to the TV? Connect- ing the headphones to the TV causes sounds not to be is- sued from 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 24 to use the MANUAL function to try to change the SYSTEM setting.

Poor picture

If noise totally obscures the picture (snow), the aerial or aer- ial cable may have trouble. Check the following to try to solve the trouble:

Has the TV and aerial been connected properly? Has the aerial cable been damaged?

Is the aerial pointed to the right direction? Is the aerial itself faulty?

If the TV or aerial receives interference from the other devic- es, stripes or noise may appear in the picture. Move such devices as an amplifier, personal computer, or a hair drier that can cause interference away from your TV, or try changing its location. If the aerial suffers interference from a radio tower or high-voltage wire, please contact your local dealer.

If the TV receives interference from signal reflecting from mountains or building, double-pictures (ghosting) will occur. Try to change the aerial’s direction or replace the antenna with the one with better directionality.

Are your COLOUR SYSTEM settings for the TV channels correct? Follow the description “COLOUR SYSTEM” on page 16 to try to solve the trouble.

Has COLOUR or BRIGHT been controlled properly? Follow the description “Picture Adjustment” on page 15 to try to ad- just 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 were coloured. It is a phenomenon 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 dis- torted. 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 to try to ad- just them properly.

When the TV channel reception is poor, it can be hard to hear the 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.

Operation disabled

Have the batteries of the remote control become exhaust- ed? Follow the description “Putting Batteries into the Re- mote Control” on page 2 and replace them with new batteries to try to solve the problem.

Have you attempted to use the remote control at the sides or rear of the TV or at a location more than seven meters apart from the TV location? Operate the remote control in the front of your TV or a location less than seven meters from your TV to try to solve the problem.

When you are viewing a teletext programme, you cannot op- erate the menus. Press the bbutton to return the teletext programme to the ordinary TV programme to try operating the menus.

If the TV operation becomes disabled suddenly, press the Main power button on the TV and turn off the main power. Try to press the Main power button again to turn on the main power. If the TV returns to a normal state, it is not a failure.
