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. 20)
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 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.

✎
Many HD channels are upscaled from SD(Standard Definition) contents.

• Compression of video contents may cause picture distortion, especially in fast moving pictures such
as sports and action movies.

• Mobile phones used close to the TV (up to 3.3ft) may cause noise in picture on analog and digital TV.

correct jacks. Incorrect or loose connections may cause color problems or a blank screen.
