2. I set the Speakers option to AV
Receiver, but hear sound from the TV
speakers instead of the A/V receiver.
Make sure the A/V receiver is connected to one of the T V’s audio
outputs (AVR AUDIO OUTPUT or DIGITAL AUDIO OUTPUT).
3. The sound does not match the screen
picture.
The TV’s Listen to: setting may be set to SAP. See page 42.
4. The sound from my A/V receiver does
not match the screen picture (I should
hear the correct audio from my A/ V
receiver).
Check that DIGITAL AUDIO OUTPUT and/or AVR AUDIO OUTPUT •
on TV’s main panel is connected to the A/ V receiver.
Without this connection, devices connected only to the TV (and
not the A/V receiver) can be heard o nly from the TV speakers.
Note that this includes the ANT 1/ANT 2 inputs, a device (such as
a camcorder) connected to the convenience jacks, and any other
device sending audio to the TV only.
Check A/V receiver input sele ction in the Inputs > AVR menu. If •
NetCommand is set up incorrectly for the A/ V receiver, see “A/V
Receiver Control: Automatic Audio Switching,” page 61.
5. The sound from my A/V receiver does
not match the screen picture (my source
device should be sending both audio
and video through the A/V rece iver).
Check A/V receiver input sele ction in the Inputs > AVR menu. •
If NetC
ommand is set up incorrectly for the A/ V receiver, see
“Setup to Control Automatic Audio and Video Switching via
HDMI,” page 64.
The TV’s •
Listen to: setting may be set to SAP. See page 42.
6. Cannot select an audio-only device; it
does not appear in the Input Selection
Menu.
Plug a video plug into any composite
VIDEO
jack for the Auto Input
Sensing screen to appear. See “Audio-Only Device,” page 28.
Picture
Symptom Remarks
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.
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.
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 to the 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 bee n incorrectly set. Reset
the PerfectColor balance.
7. Picture from an HDMI input is noisy (poor
quality).
Try using a different HDMI cable.•
If the signal is 1080p, upgrade a Category 1 (unmarked) •
HDMI cable to a Category 2 high-speed HDMI cable.
8. The image from a computer appears dis-
torted when viewed on the TV.
Normal TV operation. The TV doe s not correct distortion in the
picture from a computer because the correction pro cess may
cut off the edges of the image.
