Common Picture Problems
Symptom
Remarks
1.
Picture does not look like a high-defini-
tion picture.
Compare the picture to the TV’s test 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 sub-
scribe 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.
2.
TV has sound but no picture.
•
Press MENU on the remote control. If the menu displays, then
there is a problem with the incoming signal.
•
Check that all video inputs are plugged in firmly to the correct
input jacks.
•
Press and hold the POWER button on the control panel for ten
seconds to perform System Reset.
3.
A color program appears as a black
and white image, or the colors are dim,
or the screen is black.
•
If using component video, check that the red, green, and blue
input cables are correctly connected to the red, green, and blue
component video jacks.
•
If using composite video, check that the incoming cable is con-
nected the TV’s green Y/VIDEO jack.
4.
Picture from an HDMI input is noisy
(poor quality).
•
Compare the picture to the TV’s test picture (
Picture >
menu) to check the source of the noise.
•
Upgrade a standard (unmarked) HDMI cable to a high-speed
HDMI cable.
