Solutions and Explanations
• Set your PC's output resolution and frequency so they match the resolutions supported by the TV (p. 19).
• This is normal; "PC" is always shown on the source list, regardless of whether a PC is connected.
• If you are using a HDMI connection, check the audio output setting on your PC.
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) (p. 32)
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.
• Antenna connection: Try HD stations after performing Auto programme.
✎
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)
(p. 25)
• Adjust Energy Saving option in the TV menu. (go to
Energy Saving) (p. 31)

• 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.
