Flickering and Dimming If your Samsung Television is flickering 
or dimming sporadically, you may need 
to disable some of its energy efficient 
features such as the Eco Sensor or the 
Energy Saving feature. Follow the steps 
below with your remote to turn these 
features off or on.

Component Connections / Screen Color If you find that the color on your 
Samsung television’s screen is not 
correct or black and white, first run a 
Self Diagnosis on the TV to make sure 
there are no device issues. 
ΠSelf Diagnosis : 
Support 
→ Self  

Diagnosis → Picture Test
If the problem does not appear in the 
Picture test, make sure:  
ΠYour connections are all consistent. 
For example, if you’ve used the AV In 
jack on your TV, make sure you have 
used the AV Out jack on your video 
source.
 
ΠYou have connected to your devices 
to the correct jacks. For example, 
if you use the Component jacks,  

labeled Pb, Pr, and Y, to connect your 
TV and video source, make sure you 
have connected the blue Pb jack on 
the video source to the blue Pb jack 
on the TV, the red Pr jack on the 
source to the red Pr jack on the 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 in the Picture option  

in the Main menu:  
ΠBacklight
 
 for LED TV  / Cell Light  
for PDP TV 
, Contrast , Brightness, 
Sharpness, Color , Tint (G/R) and so 
on. Go in to  Picture on user Menu 
then try adjusting options mentioned 
above.
Blur If you find that there is a blur or 
“ghostlike” appearance to the images 
on your television’s screen, you might  

be able to correct the blurring using 
Auto Motion Plus.

Unwanted Powering Off If your Samsung TV appears to turn off 
by itself, there may be an issue with 
either your Timer settings or your Eco 
friendly No Signal Power Off feature.
First make sure Sleep Timer is not 
accidentally set. The Sleep Timer turns  

off the TV automatically after a certain 
period of time has passed. 
ΠSleep Timer: 
System 
→  Time 
→ 
Sleep Timer
If the Sleep Timer is not activated, you 
may have engaged the No Signal Power 
Off or Auto Power Off feature.  
ΠNo Signal Power Off: 
System 
→  Eco 
Solution  → No Signal Power Off
 
ΠAuto Power Off: 
System 
→  Eco 
Solution  → Auto Power Off 

Trouble Powering OnPress the power on button on the TV or 
remote and the light should blink about 5 
times before the TV turns on.
If you find that you are having trouble 
powering on your Samsung television, 
there are a number of things to check 
before making a call to the service 
department.
If you’re sure your power cord, remote 
control, and PC are functioning  

properly, you may be having a cable 
issue. If you have a cable or satellite 
box, your TV may appear to be off 
because the cable or satellite box is not 
outputting a signal. To test the signal 
output of your cable or satellite box, 
press the guide or info button on the 
cable or satellite box remote control. If 
the screen displays the guide or info 
data, the problem is caused by the box.
