Troubleshooting

Solutions and Explanations
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. 25)
If the test image is properly displayed, the poor picture may be caused by the source or signal.
• 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 up scaled from SD (Standard Definition) contents.
• Adjust the Cable/Sat box video output resolution to 1080i or 720p.
• 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.
• 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.
• Adjust the Picture options in the TV menu. (go to Picture mode / Color / Brightness / Sharpness)
(p. 15)
• Adjust Energy Saving option in the Setup menu. (go to
Energy Saving) (p. 15)
• Try resetting the picture to view the default picture settings. (go to
(p. 20)
• If the picture size is set to Screen Fit, change it to 16:9 (p. 16).
• Change cable/satellite box resolution.
• If you are using an AV composite input, connect the video cable (yellow) to the Green jack of
component input 1 on the TV.
• 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.
• If there is a problem, keep other electronic devices as far away as possible from the 3D Active
Glasses.
• If so, dim the light or turn the lamp off.
• We recommend sitting with viewer's eyes on a level with the screen.
• Turn off 3D glasses while not using them.
