Poor picture

Is a component signal output device, such as a DVD player, connected correctly? (see page 5.)

Is the VIDEO-2 SET function setting correct? (see page 13.)

If noise (snow) totally blocks out the picture, check the following.

-Have the TV and antenna been connected prop erly?

-Has the antenna cable been damaged?

-Is the antenna itself faulty?

If the TV or antenna suffer interference from other equipment, stripes or noise may appear in the picture. Move any equipment which can cause interference away from the TV.

If the TV or antenna suffer interference from signals reflecting from mountains or buildings, double-pictures (ghosting) will occur. Change the antenna’s direction or replace it with an antenna with better directionality.

When a white and bright still image (such as a white dress) is displayed on the screen, the white part may look as if it is colored. When the image disappears from the screen, the unnatural colors will also disappear.

The picture is tilted
