Common Picture Problems
Symptom

Picture does not look like a high-defini-
tion picture.
2.
TV has sound but no picture.
3.
A color program appears as a black and
white image, or the colors are dim, or
the screen is black.

Remarks
Compare the picture to the TV's test picture (Picture > Picture+ menu)
to check if the source signal is supplying a lesser-quality image.
Not all signals are high-definition signals. To receive high-definition
programming from your cable or satellite provider, you must subscribe
to the provider's high-definition service. Some over-the-air broadcasts
are in high-defi nition and can be received with a high-quality antenna
suited to your location.
