If a setting option appears in gray, this indicates that the settings option is unavailable
in current input mode.
TV cabinet creaks
!
When the TV is in use, there is a natural rise in temperature, causing the cabinet to
expand or contract and may be accompanied by a slight creaking noise. This is not a
malfunction.
Control buttons do not operate
!
Disconnect the power cord and wait for a few seconds. Then re-plug the power cord
and turn on the unit again.
Some occasional operating “glitches” can be solved by unplugging and replugging the AC power cord.
Never attempt to repair a defective TV yourself.

Problem
Possible Solutions
A pixel of the screen does not light
up.
The display panel is manufactured using an extremely high level of precision technology,
however, sometimes 1or 2 pixels of the screen may be missing picture elements or have
luminous spots. This is not a malfunction.
Display panel
After-images appear
Do not allow a still picture to be displayed for an extended period, as this can cause a
permanent after-image to remain more so on a Display Panel.
Examples of still pictures include logos, video games, computer images, teletext and
images displayed in 4:3 mode.
Note:
The permanent after-image on the Display resulting from fixed image use is not an
operating defect.
This product is not designed to display fixed images for extended periods of time.
Snapping sounds may be heard from
the display unit.
This sound is produced when the cabinet expands or contracts due to variations in
temperature and is not a malfunction.
