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 > 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.
• The PerfectColor color balance has been incorrectly set. Reset
the PerfectColor balance.
4. Picture from an HDMI input is noisy
(poor quality). • 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.
Network
Symptom Remarks
I cannot connect the TV to the network. Go the Setup > Network menu. Obtain the TV MAC address and
provide it to the router.
