Solutions and Explanations

 

 

Flickering and Dimming

Try disabling some of the TV's energy efficiency features.

 

Disable Energy Saving (System > Eco Solution > Eco Sensor) and/or Energy

 

Saving (System > Eco Solution > Energy Saving) and check again.

 

 

Screen Color is Not Correct

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.

 

 

Screen Brightness

Adjust the following settings:

 

Navigate to Picture and adjust Backlight, Contrast, Brightness, Sharpness,

 

Color, Tint (G/R) and other picture quality adjustment settings.

 

 

Blurred Images

Turn on Auto Motion Plus (Picture > Picture Options > Auto Motion Plus).

 

 

Unwanted Powering Off

Check if Sleep Timer (System > Time > Sleep Timer) has been enabled.

 

Sleep Timer automatically turns off the TV after an amount of time that

 

you select. If the Sleep Timer has not been enabled, see if No Signal Power

 

Off (System > Eco Solution > No Signal Power Off) or Auto Power Off

 

(System > 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 Power Off turns off the TV if there has been no

 

user input in four hours.

 

 

Trouble Powering On

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 Start Guide.
