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 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.
•
Press and hold the • POWER button on the control panel for ten
seconds to perform System Reset.
3. You cannot view a picture when playing a
VHS tape. Check your VCR’s owner’s guide for further troubleshooting.
4. 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.
5. When viewing a stopped VCR, white lines
are rolling on the screen. • Turn off video mute for the VCR.
• Begin playing the tape.
• Change the VCR input from Line 1 to the VCR antenna input.
6. A color program appears as a black and
white image, or the colors are dim, or the
screen is black. The PerfectColor color balance has been incorrectly set. Reset
the PerfectColor balance.
7. Picture from an HDMI input is noisy (poor
quality). Upgrade a standard (unmarked) HDMI cable to a high-speed
HDMI cable.
8. The image from a computer appears dis-
torted when viewed on the TV. Normal TV operation. The TV does not correct distortion in •
the picture from a computer because the correction process
may cut off the edges of the image.
The aspect ratio may be wrong for the image. Press
• FORMAT
to change.
