•When the SLEEP TIMER function or AUTO

this time, if the TV resumes a normal state, there is
no problem.
•If you do not want sound emitted from the TV’s
speakers when using headphones, change the TV
SPEAKER setting in the HEADPHONE menu to
OFF. For details, see “HEADPHONE” on page 20.
•If you bring a magnetised 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.
•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 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.
•If you jolt this TV, the picture may shake.
This is not a malfunction.
