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
c 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 R button and display the sub-picture again.
• The headphone volume is adjusted with the
"HEADPHONE" menu. It cannot be adjusted with the
r (volume) q buttons.
• When TV SPEAKER in the "HEADPHONE" menu is
ON, even if the headphones are connected, sound is
emitted from the TV speaker. When you do not want to
emit sound from the TV speaker, turn the setting OFF.
• Even if the PICTURE SHIFT function is turned off, the
picture may shift to the left or right when the channel or
input is changed. This is to prevent burn-in and is not a
fault.
