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

The picture is black and white. If you are using an AV composite input,  

connect the video cable (yellow) to the 
Green jack of Component 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. 

Sound (Troubleshooting)
First, perform the Sound Test to 
determine if your TV audio is operating 
properly. (Go to  Support 
→ Self 
Diagnosis  → Sound Test).
If the audio is OK, the sound problem 
may be caused by the source or signal.
There is no sound or the sound is too low 
at maximum volume. Please check the volume of the device 
(Cable/Sat Box, DVD, Blu-ray etc.)  

connected to your TV.
The picture is good but there is no sound. Set the Speaker Select option to  TV 
Speaker in the Sound  menu.
If you are using an external device, 
check the device’s audio output option. 
(Ex. You may need to change your 
cable box’s audio option to HDMI if 
you have the box connected to your TV 
using an HDMI cable.)
If you are using a DVI to HDMI cable, a  

separate audio cable is required.
If your TV has a headphone jack, make 
sure there is nothing plugged into it.
Reboot the connected device by 
disconnecting, and then reconnecting 
device’s power cable.
The speakers are making an inappropriate 
noise. Check cable connections. Make sure 
a video cable is not connected to an 
audio input. 

For antenna or cable connections, check 
the signal information. A low signal 
level may cause sound distortion.
Perform the Sound Test feature. 
(Support → Self Diagnosis 
→ Sound 
Test ) 

Antenna (Air / Cable) Connection (Troubleshooting)
The TV is not receiving all channels.
Make sure the coaxial cable is 
connected securely.
Run  Auto Program to add available 
channels to the channel list. Go to 
Channel  → Auto Program then select 
Cable and make sure to select the 
correct Cable TV signal type. There are 
3 options, STD, HRC and  IRC. Most 
cable systems use STD. 

Verify the antenna is positioned 
correctly.
No caption on digital channels. Check the Caption Setup menu. Try 
changing  Caption Mode Service1 to 
CC1 .
Some channels may not have caption 
data.
The picture is distorted: macro block error, 
small block, dots, pixelization. The compression of video contents may  

cause picture distortion, especially with 
fast moving pictures such as sports and 
action movies.
A weak signal can cause picture 
distortion. This is not a TV problem.
