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.
