troubleshooting tips apply, visit www.samsung.com/support or call Samsung Customer Service.
Issues
Solutions and Explanations
Flickering and Dimming
If your Samsung Television is flickering or dimming sporadically, you may need to disable some
of the energy efficiency features.
Disable
Energy Saving
(
System
>
Eco Solution
>
Energy Saving
) and check again.
Component Connections /
Screen Color
If you find that the color on your Samsung television screen is not correct or the black and white
colors are off, 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
If you find that the colors on your Samsung TV are correct but just a little too dark or bright, try
adjusting the following settings first.
Navigate to
Picture
and adjust
Backlight
,
Contrast
,
Brightness
,
Sharpness
,
Color
,
Tint (G/R)
and other
picture quality adjustment settings.
Unwanted Powering Off
If your Samsung TV appears to turn off by itself, try disabling some of the TV's energy efficiency
and automatic off features. 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
When the TV is turned on, the remote control receiver flashes 5 times before the screen turns on.
If you find that you are having problems powering on your Samsung television, there are a
number of things to check before calling the service department.
If the power cord is connected properly and the remote control is operating normally, the
problem might be with the antenna cable connection or the cable/satellite box not being turned
on. Check the antenna connection or turn on the cable/satellite box.
Stand Assembly
If you have any trouble assembling the stand, review the stand assembly instruction in the Quick
Start Guide.
