Solution
First of all, please perform the Picture Test to 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 analog Cable/Set top box, upgrade to the box. Use HDMI or Component
cables to deliver HD picture quality. (Not applied to HD Tuner Built-in models)
● Cable/Satellite subscriber : Try HD(High Definition) stations from channel line up.
● Antenna connection: Try HD stations after performing Auto program.
Many HD channels are upscaled from SD(Standard Definition) contents.

Tuner Built-in models)
● Compression of video contents may cause picture distortion especially on fast moving
pictures such as sports and action movies.
● Low signal level can cause picture distortion. This is not a TV issue. Have the antenna
accessed.

connections may cause color problems or the screen will be blank.

Sharpness).

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

have HDMI connected to your TV.)
● If you are using a DVI to HDMI cable, a separate audio cable is required.
