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 success, 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 rearcover 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
•Are your SOUND SYSTEM settings for the TV channels correct?
Forrow the description "SOUND SYSTEM Button" on page 11 to try to solve the trouble.
Poor picture
•If red, green, and blue shadows appear around the contours of the image on the screen it is necessary to adjust CRT colour convergence. For details, refer to “Adjusting CRT colour convergence” on Page 6.
•If noise totally obscures the picture (snow), the aerial or aerial 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 devices, stripes or noise may appear in the picture. Move such device 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
•If the TV receives interferences 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 button" on pege 11 to try to solve the trouble.
•Has COLOUR or BRIGHT been controlled properly? Follow the description "Adjusting the picture" on page 17 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 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 softwear products, or videos from videotapes which have been recored improperly, the top of the image may be distored.
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 "Adjusting the Sound" on page 20 to try to adjust 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 20 to hear the sound more easily by changing it to a mono sound.
