Troubleshooting

•When a white and bright still image (su- ch 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 vi- deos 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 24 to try to adjust them properly.

•When the TV channel reception is poor, it can be haed to hear the stereo or bilingual sound. In this case, follow the description "STEREO / I • II" on page 24 to hear the sound more easily by changing it to a mono sound.

Operation disabled

•Have the batteries of the remote control become exhausted?

Follow the description "Putting the Batteries into the Remote Control" on page 4 and replace them with new batteries to try 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 locatin? 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 ploblem.

•When you are viewing a teletext progra- mme, you cannot operate the menus. Press the TV/VIDEO button to return the teletext programme to the ordinary TV programme to try operating the menus.

•Is the CHILD LOCK function set to ON? If the CHILD LOCK function is set to ON, you cannot operate the TV with the front control buttons of the TV. Follow the description "CHILD LOCK" on page 26 to try to set the CHILD LOCK function to OFF.

•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.

• The following functions do not operate when receiving Progressive Video Signal (525P signal);

Remote control function: ZOOM, PIP, MULTI, FREEZE and

STROBE BUTTON MENU function:

SHARP, TINT, DIGITAL VNR, Digipure and ZOOM

Other concerns

•When the SLEEP TIMER function or AUTO SHUTOFF function operates, the

TV is automatically turned off.

If the TV is turned off suddenly, try to press the POWER button to turn on the TV once again. At this time, if the TV resumes a normal state, there in no problem.

•If you do not want sound emitted from the TV’s speakers when using headphones, change the TV SPEAKER setting in the HEADPHONE menu to OFF. For details, see “HEADPHONE” on page 25.

•If you bring a magnetised device such as a speaker near to your TV, a picture may be warped or unnaural colours appear at the corners of the screen.

In this case, keep the device apart from your TV. If the speaker causes such phenomena, use the magnetic-shielded speaker instead.

•A picture may be tilted due to the influe-

nce of the earth's magnetism. In this
case, use the "PICTURE TILT" on page	41
23 to complete the tilt.
