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.
• 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.
• When the correct picture has not been displayed on screen,
the following error messages will display on screen.
NO SIGNAL - TV received no signal from PC, you may
check your PC is working correctly or not.
OUT OF RANGE - The picture resolution is out of limit.
Ensure that the PC picture resolution is set correctly.
