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 high-voltage wire, please contact
your local dealer.
•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.
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.
•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.
