• Set your PC’s output resolution so it match the resolutions supported by the TV (p. 19).
PC
is always shown on the source list,
even if a PC is not connected.
• This is normal; “PC” is always shown on the source list, regardless of whether a PC is connected.
The video is OK but there is no audio.
• If you are using an HDMI connection, check the audio output setting on your PC.
Poor picture
First of all, please perform the
Picture Test
and confirm that your TV is properly displaying the test image.
(go to
MENu
-
Support - Self Diagnosis - Picture Test
) (p. 32)
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.
• If you have an analog cable/satellite box, upgrade to an HD digital set top box. Use HDMI or
Component cables to deliver HD (high definition) picture quality.
• Cable/Satellite subscribers: Try HD stations from the channel line up.
• Antenna connection: Try HD stations after performing Auto program.
✎
Many HD channels are upscaled from SD(Standard Definition) contents.
• Adjust the Cable/Sat box video output resolution to 1080i or 720p.
• Make sure you are watching the TV at the minimum recommended distance based on the size and
definition of the signal.
The picture is distorted: macroblock error,
small block, dots, pixelization.
• Compression of video contents may cause picture distortion, especially in fast moving pictures such
as sports and action movies.
• Low signal level can cause picture distortion. This is not a TV problem.
• Mobile phones used close to the TV (cca up to 1m) may cause noise in picture on analog and digital
TV.
Color is wrong or missing.
• If you’re using 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.
There is poor color or brightness.
• Adjust the
Picture
options in the TV menu (go to
Picture
mode /
Color / Brightness / Sharpness
)
(p. 25)
• Adjust
Energy Saving
option in the TV menu (go to
MENu

Saving
) (p.30)
• Try resetting the picture to view the default picture settings (go to
MENu
-

(p. 27)
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
(p.25).
• Change 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 jack of
component input 1 on the TV.
When changing channels, the picture
freezes or is distorted or delayed.
• If connected to a cable box, please try to reset it. (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 Problem
First of all, please perform the
Sound Test
to confirm that your TV audio is properly operating.
(go to
MENu
-
Support - Self Diagnosis - Sound Test
) (p. 32)
If the audio is OK, the sound problem may 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 (p. 28).
• If you are using an external device, make sure the audio cables are connected to the correct audio
input jacks on the TV.
• 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 when you have a HDMI connected to your TV).
• 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 reconnecting the device’s power cable.
