Picture
Symptom Remarks
7. VCR or DVD player’s on-screen menus jitter
up and down.
Possible cause: Many VCRs and DVD players provide on-
screen menus at only half-resolution. These lower-resolution
graphics may appear to jitter up and down when the TV con-
verts them to high-definition graphics.
8. 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 to the antenna input.
9. Screen is black. The PerfectColor™ color balance has been incorrectly set.
Reset the PerfectColor balance.
10. Picture from an HDMI input is noisy (poor
quality).
Upgrade a Category 1 (unmarked) HDMI cable to a Category 2
HDMI cable.
11. 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
cause the edges of the image to be cut off.
