There is a problem with the picture
Testing the Picture
MENU > Support >  Self Diagnosis >  Picture Test Try Now
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 definition picture you can examine for 
flaws 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 flickering or dimming sporadically, you may need 
to disable some of the energy efficiency 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:  
● Confirm 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, confirm 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 first.
 
● Go to the Picture menu and adjust the Backlight/Cell Light
 (available on 
different models)  Contrast, Brightness, Sharpness, Color, and  Tint (G/R) 
settings.
In HDMI mode, there is 
something wrong with 
the screen. HDMI UHD Color
 is specific to a UHD source, and does not operate properly for 
any other source. In this case, navigate Picture >  Picture Options > HDMI UHD 
Color menu, and then set the HDMI UHD Color -enabled HDMI connector to Off.
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.
Unwanted Powering 
Off If your Samsung TV appears to turn off by itself, try disabling some of the TV's 
energy efficiency features. See if 
Sleep Timer (System >  Time > Sleep Timer ) has 
been enabled. The Sleep Timer  automatically turns the TV off after a specified 
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.

Problems Powering On When the TV is turned on, the remote control receiver flashes 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. Confirm 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 firmly 
connected. If you have a cable/satellite box confirm that it is plugged in and 
turned on.
Unable to find a 
Channel If your TV is not connected to a cable box or satellite box, run Setup
 (System > 
Setup ) or Auto Program ( Broadcasting > Auto Program).
The TV image does not 
look as good as it did 
in the store. Store displays are all tuned to digital, HD (high definition) channels.
If you have an analog cable/set top box, upgrade to a digital set top box. Use 
HDMI or Component cables to deliver HD (high definition) picture quality.
Many HD channels are upscaled from SD (Standard Definition) content. Look for a 
channel that is broadcasting true HD content.
 
● Cable/Satellite Subscribers: Try HD channels from the channel lineup.
 
● Air/Cable Antenna Connection: Try HD channels after running the Auto Program 
function.
Adjust the cable/satellite box's video output resolution to 1080i or 720p.
The picture is distorted. The compression of video content may cause picture distortions, especially in fast 
moving pictures from sports programs and action movies.
A weak or bad quality signal can cause picture distortions. This is not an issue 
with the TV.
Mobile phones used close to the TV (within 3.2 ft) may cause noise in analog and 
digital channels.
The color is wrong or 
missing. If you’re using a Component connection, make sure that the Component cables are 
connected to the correct jacks. Incorrect or loose connections may cause color 
problems or a blank screen.
The color is poor or 
the picture is not bright 
enough. Go to the Picture menu and then adjust the Picture Mode
, Brightness, Sharpness, 
and  Color settings.
See if Energy Saving  (System >  Eco Solution  > Energy Saving ) has been enabled.
Try resetting the picture. ( Picture > Picture Reset)
There is a dotted line 
on the edge of the 
screen. If the Picture Size has been set to 
Screen Fit, change the setting to  16:9.
Change the cable/satellite box resolution.
The picture is black 
and white. If you are using AV composite input, connect the video cable (yellow) to the TV's 
green component jack.

I can't hear the sound clearly
Testing the Sound
MENU > Support >  Self Diagnosis >  Sound Test Try Now
Before you review the list of problems and solutions below, make sure that the TV Sound Output  menu 
item is set to TV Speaker, and then listen to the speakers again. If the TV still does not play audio, 
run the Sound Test. The Sound Test uses a built-in melody to check for sound problems. If the TV 
does not play sound during the Sound Test, or the sound is distorted, there may be a problem with 
the TV. Contact Samsung’s Call Center for assistance. If the TV plays the Sound Test melody without 
distortion, there may be a problem with an external device. Please check the connections. If the 
problem persists, refer to the external device’s user manual.
The Problem Try this!
There is no sound or 
the sound is too low at 
maximum volume. Check the volume control of the device (cable/satellite box, DVD, Blu-ray, etc.) 
connected to your TV.
The picture is good but 
there is no sound. Set Sound > 
Speaker Settings  > TV Sound Output  to TV Speaker.
If you are using an external device, check the device’s audio output option. (For 
example, you may need to change your cable box’s audio option to HDMI if the 
box connected to your TV is using an HDMI cable.)
To listen to the computer sound, connect the external speaker to the computer’
s audio output connector.
If your TV has a headphone jack, make sure there is nothing plugged into it.
Reboot the connected device by disconnecting and then reconnecting the 
device’s power cable.
The speakers are making 
an odd sound. Make sure that the audio cable is connected to the correct audio output 
connector on the external device.
For antenna or cable connections, check the signal information. A low signal 
level may cause sound distortions.

Other Issues
The ProblemTry this!
The TV is hot. Watching TV for an extended period of time causes the panel to generate heat. 
The heat from the panel is dissipated through internal vents running along the 
top of the TV. The bottom, however, may feel hot to the touch after extended 
use. Children watching TV need constant adult supervision to prevent them from 
touching the TV. This heat, however, is not a defect and does not affect the TV's 
functionality.
The picture won’t 
display in full screen. HD channels will have black bars on either side of the screen when displaying 
upscaled SD (4:3) content.
Black bars will appear at the top and bottom of the screen when you watch 
movies that have aspect ratios different from your TV.
Adjust the picture size options on your external device or set the TV to full 
screen.
The "Mode Not 
Supported" message 
appears. The output resolution of the attached device is not supported by the TV. Check 
the TV's supported resolutions and adjust the external device’s output resolution 
accordingly.
The Captions item in the 
TV menu is grayed out. You cannot select the Caption
 menu if you have selected a source connected to 
the TV via HDMI or Component. To view captions, turn on the external device's 
caption function.
The TV smells of plastic. This smell is normal and will dissipate over time.
