Solutions and Explanations
Poor picture
First, perform the
Picture Test
and to see if your TV is properly displaying the test
image.
• Go to
MENU
-
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 typically tuned to digital, HD (high definition) channels.
• If you have an analog cable/satellite box, upgrade to a digital set top box. Use
HDMI or Component cables to deliver HD (high definition) picture quality.
• Cable/Satellite subscribers: Try HD channels from the channel line up.
• Air/Cable Antenna connection: Try HD channels after performing an Auto
program.
✎
Many HD channel programs are up scaled from SD (Standard Definition)
content. Look for a channel that is broadcasting true HD content.
• Adjust the Cable/Set top box video output resolution to 1080i or 720p.
The picture is distorted:
macroblock error, small block,
dots, pixelization.
• The compression of video contents may cause picture distortion, especially in
programs with fast moving pictures such as sports programs and action movies.
• A weak signal can cause picture distortion. This is not a TV problem.
• 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.
There is poor color or brightness. • 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
MENU
- System - Eco
Solution - Energy Saving
)
• Try resetting the picture to the default picture settings. (go to
MENU
- 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 jack of Component input 1 on the TV.
When changing channels, the
picture freezes or is distorted or
delayed.
• If the TV is connected to a cable box, reset the box. (Disconnect and then
reconnect the AC cord, and then 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, perform the
Sound Test
to determine if your TV audio is operating properly.
• Go to
MENU
- 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.
• Reboot the connected device by disconnecting and then reconnecting the
device’s power cable.
The speakers are making an
inappropriate noise.
• Check the cable connections. Make sure a video cable is not connected to an
audio input.
• For Antenna or Cable connections, check the signal information. A weak signal
may cause sound distortion.
• Perform the
Sound Test
as explained above.
