4-1-2. Troubleshooting
Picture Quality
First of all, please perform the Picture Test and confirm that your TV is properly displaying test image.
MENU • → Support → Self Diagnosis → Picture Test
Problem Solution
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.
Cable/Satellite subscribers: Try HD channels from the channel line up.
•
Air/Cable Antenna connection: Try HD channels after performing Auto program. NNMany
•
HD channels are up scaled from SD (Standard Definition) contents. Look for a channel
that is broadcasting true HD content.
Adjust the Cable/Sat box video output resolution to 1080i or 720p.
•
The picture is distorted: macro
block 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 or bad quality can cause picture distortion. This is not a TV issue.
•
Mobile phones used close to the TV (cca up to 1m) may cause noise in picture on analog
•
and digital TV.
There is poor color or brightness. Adjust the Picture options in the TV menu.
•
Picture mode / Color / Brightness / Sharpness -
Adjust Energy Saving option in the TV menu.
•
MENU → System → Eco Solution → Energy Saving
-
Try resetting the picture to view the default picture settings.
•
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 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.
•
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.
3D
Problem Solution
The 3D Active Glasses may not work properly if there is any other
3D product or electronic devices turned on near the glasses or TV.
If there is a problem, keep other electronic devices
•
as far away as possible from the 3D Active Glasses.
You may notice a small amount of screen flickering when watching
3D images in poor light conditions (from a strobe light, etc.), or
under a fluorescent lamp (50Hz ~ 60Hz) or 3 wavelength lamp.
If so, dim the light or turn the lamp off.
•
The ideal viewing distance should be three times or more the
height of the screen.
We recommend sitting with viewer’s eyes on a level
•
with the screen.
If you leave 3D glasses on, battery lifespan is shortened.
Turn off 3D glasses while not using them.
