Solutions and Explanations
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 > Eco Sensor) and/or Energy Saving (System > Eco
Solution > Energy Saving) and check again.
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 jacks are connected to the correct external video
device output jacks and that none of the connections are loose. Finally, if possible, test your external
video devices by connecting them to another TV.
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.
If you ﬁnd that there is a blur or "ghost" shadow to the images on your television screen, you might be
able to correct the issue using Auto Motion Plus (Picture > Picture Options > Auto Motion Plus).
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.
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.
If you have any trouble assembling the stand, review the stand assembly instruction in the Quick Start
Re-run Setup (Go to Menu > System > Setup) or run Auto Program. (Go to Menu > Broadcasting >
