Samsung Television UNES7150 User Manual

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.
Stand Assembly If you have any trouble assembling the 
stand first, review "Install the Stand" in 
the paper manual.

Picture (Troubleshooting)First, perform the Picture Test to see if 
your TV is properly displaying the test 
image (go to  Support 
→ Self Diagnosis 
→  Picture Test).
If the test image is properly displayed, 
the poor picture may be caused by the 
source or signal.
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.
 
NMany HD channels are up scaled 
from SD (Standard Definition) 
contents. Look for a channel that is 
broadcasting true HD content.
 
ΠCable/Satellite subscribers: Try HD  

channels from the channel line up.
 
ΠAir/Cable Antenna connection: Try 
HD channels after performing an 
Auto Program.
Adjust the Cable/Sat box video output 
resolution to 1080i or 720p.
The picture is distorted: macro block error, 
small block, dots, pixelization The compression of video contents 
may cause picture distortion especially 
in fast moving pictures such as those  

in sports and action movies.
A weak or bad quality signal can cause 
picture distortion. This is not a TV 
issue.
Mobile phones used close to the TV 
(within 3.3 ft) may cause noise in the 
picture on analog and digital channels.
Color is wrong or missing. If you’re using a Component 
connection, make sure 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. Adjust the Picture options in the TV 
menu (go to  Picture Mode /  Color / 
Brightness /  Sharpness)
Adjust the Energy Saving option in the 
TV menu (go to System  → 
Eco Solution  
→  Energy Saving) 

Try resetting the picture to view the 
default picture settings (go to Picture 
→  Reset Picture).
There is a dotted line on the edge of the 
screen. If the Picture Size is set to Screen Fit, 
change it to  16:9.
Change the cable/satellite box 
resolution.
The picture is black and white. If you are using an AV composite input,  

connect the video cable (yellow) to the 
green Y Component jack on the TV.
When changing channels, the picture 
freezes or is distorted or delayed. If the TV is connected to a cable box, 
try to reset the box. (Disconnect and 
then reconnect the AC cord and wait 
until the cable box reboots. It may take 
up to 20 minutes.)
Set the output resolution of the cable 
box to 1080i or 720p.
