Picture
Symptom Remarks
1. Picture does not look like a high-definition
picture.
Not all signals are high-definition signals. To receive high-defini-
tion programming from your cable or satellite provider, you must
subscribe to the providers 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. Check that all video inputs are plugged in firmly.•
Press and hold the POWER button on the control panel for •
ten seconds to perform System Reset.
3. There is a large black or gray rectangle on
the screen.
The TV’s analog closed captioning has been set to “text” mode
in the Captions menu. Turn off because there is no text informa-
tion being broadcast.
4. You cannot view a picture when playing a
VHS tape.
Check your VCR’s owner’s guide for further troubleshooting.
5. VCR or DVD player’s on-screen menus jitter
up and down.
Stop playback. Possible cause: Many VCRs and DVD players
provide on-screen menus at only half-resolution that may
appear to jitter up and down.

are rolling on the screen.

quality).
Upgrade a Category 1 (unmarked) HDMI cable to a Category 2
high-speed HDMI cable.
