Other concerns:
When the SLEEP TIMER function operates, the TV is auto matically 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 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.
The top of the TV and the screen may become hot during use but this has no effect 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.
