Before you review the list of problems and solutions below, use Picture Test to determine if the problem is caused by
the TV. The Picture Test displays a high denition picture you can examine for aws or faults. If the test picture does not
appear or there is noise or distortion, the TV may have a problem. Contact Samsung’s Call Center for assistance. If the
test picture is displayed properly, there may be a problem with an external device. Please check the connections. If the
problem persists,check the signal strength or refer to the external device’s user manual.
The Problem Try this!
Flickering and Dimming.
If your Samsung Television is ickering or dimming sporadically, you may need
to disable some of the energy efciency features. Disable Energy Saving (System >
Eco Solution > Energy Saving) or Eco Sensor (System > Eco Solution > Eco Sensor).
Component Connections/
Screen Color
If the color on your Samsung television screen is not correct or the black and
white colors are off, run Picture Test (Support > Self Diagnosis > Picture Test).
If the test results indicate that the problem is not caused by the TV, do the
following:
Conrm that the TV’s video input connectors are connected to the correct external •
device video output connectors.
Check the other connections as well. If the TV is connected to an external device •
via a component cable, conrm that the Pb, Pr, and Y jacks are plugged into their
proper connectors.
Screen Brightness
If the colors on your Samsung TV are correct but just a little too dark or bright, try
adjusting the following settings rst.
Go to the Picture menu and adjust the Backlight/Cell Light (available on different •
models) Contrast, Brightness, Sharpness, Color, and Tint (G/R) settings.
Ghosting, Blurring, or
Juddering
If you notice ghosting or blurring on the screen, use the Auto Motion Plus option
(Picture > Picture Options > Auto Motion Plus) to resolve the issue.

using LED Clear Motion (Picture > Picture Options > LED Clear Motion).
Unwanted Powering Off
If your Samsung TV appears to turn off by itself, try disabling some of the TV’s energy
efciency features. See if Sleep Timer (System > Time > Sleep Timer) has been
enabled. The Sleep Timer automatically turns the TV off after a specied period of
time. 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 and disable them.

When the TV is turned on, the remote control receiver ashes 5 times before the
screen turns on.
If you are having problems powering on your Samsung television, there are a number
of things to check before calling the service department. Conrm that the TV’s power
cord is connected correctly at both ends and that the remote control is operating
normally. Make sure that the antenna cable or cable TV cable is rmly connected. If
you have a cable/satellite box conrm that it is plugged in and turned on.
