Solutions and Explanations
Try disabling some of the TV's energy efficiency features.
Disable Energy Saving ( System > Eco Solution > Energy Saving ) and check
again.
Run a Self Diagnosis Picture Test ( Support > Self Diagnosis > Picture Test ).
If the picture problem is caused by the TV, the problem should be visible in
the Picture Test. If the problem is not visible, next confirm that the TV's video
input ports are connected to the correct external video device output ports
and that none of the connections are loose. Finally, if possible, test your
external video devices by connecting them to another TV.
Adjust the following settings:
Navigate to Picture and adjust Backlight , Contrast , Brightness , Sharpness ,
, Tint (G/R) and other picture quality adjustment settings.
Color
Check if Sleep Timer ( System > Time > Sleep Timer ) has been enabled. Sleep
automatically turns off the TV after an amount of time that you select.
Timer
If the Sleep Timer has not been enabled, see if No Signal Power Off ( System >
> No Signal Power Off ) or Auto Power Off ( System > Eco Solution
Eco Solution
> Auto Power Off ) has been enabled. No Signal Power Off turns off the TV
if no signal has been received by the TV for a specified period time. Auto
turns off the TV if there has been no user input in four hours.
Power Off
Confirm that the power cord is connected and that the remote has live
batteries and is functioning correctly. If the power cord is connected
properly and the remote control is operating normally, there might be a
problem with the antenna cable connection or the cable/satellite box might
not be turned on. Check the antenna connection or turn on the cable/
satellite box.
If you have any trouble assembling the stand, review the stand assembly
instruction in the Quick Setup Guide.
Re-run Setup (Go to MENU > System > Setup ) or run Auto Program . (Go to
MENU > Broadcasting > Auto Program ).
