Troubleshooting (continued)
POOR SOUND
Have you adjusted BASS or TREBLE
properly? If not, follow the description
“Adjusting the sound” on page 11 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 11 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 6 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 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 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 15 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.
OTHER CONCERNS
When the AUTO SHUTOFF function oper-
ates, 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 is no problem.
If you bring a magnetized device such as a
speaker near to your TV, a picture may be
warped or unnatural 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 influence
of the earth’s magnetism. In this case, use
the “PICTURE TILT” on page 9 to complete
the tilt.
It takes a short period of time from the time
an operation such as changing channels is
per-formed until an image is displayed. This
is not a malfunction. This is the time
required for the image to stabilize before it
can be displayed.
The TV may emit a crackling sound due to a
sudden change in temperature. It does not
matter if a picture or sound does not show
any abnormality. If you hear crackling
sounds frequently while you are viewing the
TV, other causes may be assumed. For
precautionary purposes, request your
service technician to inspect it.
•Touching the screen may cause you feel a
slight electric shock due to its static electric-
ity. It is an unavoidable phenomenon due to
the construc-tion of the picture tube. It is not
a problem with the TV. You can rest assured
that this static discharge does not have
harmful influence over the human body.
