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-definition 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.
