Common Picture Problems
Symptom
1. 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.
4. Picture from an HDMI input is noisy
(poor quality).
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.
• 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.
• If using component video, check that the red, green, and blue input
cables are correctly connected to the red, green, and blue compo-
nent video jacks.
• If using composite video, check that the incoming cable is con-
nected the TV's green Y/VIDEO jack.
• Compare the picture to the TV's test picture (Picture > Picture+
menu) to check the source of the noise.
• Upgrade a standard (unmarked) HDMI cable to a high-speed HDMI
cable.
