Other concerns
• When the SLEEP TIMER function operates, the TV is
automatically turned off. If the TV suddenly turns off,
try to press the (standby) button to turn on the TV
once again. If the TV goes back to normal, there is no
problem.
• When the TV is receiving a wide-screen signal (WSS) or
a signal from an external device affecting the screen
size, the ZOOM mode automatically changes. When you
want to resume the previous ZOOM mode, press the
button again.
• It takes a short period of time from the time an operation
such as changing channels is performed 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 make a crackling sound due to a sudden
change in temperature. The picture or sound may be
normal. If you hear crackling sounds frequently while
you are viewing the TV, there may be other causes. As a
precaution, ask your service technician to inspect it.
• In the twin pictures mode the sub-picture may disappear
when the external device is operated. If this happens,
press the button and display the sub-picture again.
• The top of the TV and the screen may become hot during
use but this has no affect on the performance of the TV.
Ensure that the ventilation holes are not blocked.
• When the picture is unstable, the screen may become
white for a moment. This occurs when the signal which
drives the liquid crystal is missing. This is not a
malfunction.
• When a still image has been displayed for a long period,
a faint residual image may remain on the screen for a
short time after the power has been turned off or when
another image is displayed. This is not a malfunction and
the image will eventually disappear.
