Solutions and Explanations
First of all, please perform the Picture Test and confirm that your TV is properly displaying test
image. (go to MENU - Support - Self Diagnosis - Picture Test) If the test image is properly
displayed, the poor picture may caused by the source or signal.
• If you have an analogue 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 stations from the channel line up.
• Aerial connection: Try HD stations after performing Auto tuning.
• Many HD channels are up scaled from SD (Standard Definition) contents.
Adjust the Cable/Set top 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.
• 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 analogue
and digital TV.
• If you're using a component connection, make sure the component cables are connected to
the correct jacks. Incorrect or loose connections may cause colour problems or a blank screen.
• Adjust the Picture options in the TV menu. (go to Picture Mode / Colour / Brightness /
Sharpness)
• Adjust Energy Saving option in the TV menu. (go to
Energy Saving)
• Try resetting the picture to view the default picture settings. (go to
Picture)
• If the picture size is set to Screen Fit, change it to 16:9.
• 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 with a cable box, please try to reset the cable box. 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.
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)
If the audio is ok, the sound problem may be caused by the source or signal.
• Please check the volume of the device (Cable/Sat Box, DVD, Blu-ray etc) connected to your TV.
• Set the Speaker Select option to TV Speaker in the sound menu.
• 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.
Reboot the connected device by reconnecting the device's power cable.
