The TV has pixels (dots) that are always dark.
• Your HDTV is precision-manufactured using an extremely
high level of technology. However, sometimes pixels may
not display correctly. These types of occurrences are
inherent to this type of product and do not constitute a
defective product.
The display image does not cover the entire screen.
• Some programs have black bars on the top or sides of
the picture so that the picture keeps its original shape.
Examples include wide-screen movies and older television
programs.
• Press the WIDE button on the remote to change the width
of the image. See
Changing the Screen Aspect Ratio

etc.).
