-
page 51). If no device is

Poor composite or S-video picture
•
If the TV is connected to an external A/V device (e.g.,
DVD player, video game system, set-top box, etc.) try
using a
ColorStream
or
HDMI
video connection
instead.
•
If you connect an S-video cable, be sure to disconnect the
standard (composite) video cable. Do not connect both
types of video cable at the same time.
Picture and sound are out of sync
•
As with all products that contain a digital display, in rare
instances, when viewing certain content (e.g.. television
broadcasts, video games, DVDs), you may notice that the
sound and picture are slightly out of sync. This
phenomenon can be caused by various factors including,
without limitation, video processing within the TV, video
processing in an attached gaming system, and video
processing or different compression rates used by
broadcasters in their programming. You may want to try
one or more of the following suggestions, which may
help to reduce the effect of this phenomenon:
– If the TV is connected to an A/V receiver that has a
programmable audio delay feature, use this feature to
help synchronize the sound to the picture.
– If you notice this phenomenon only on certain TV
channels, please contact your local broadcast, cable, or
satellite provider to inform them of this issue.
LED indications while in reboot from standby
•
When you plug the power cord in, the yellow LED will
blink until the TV enters standby mode, (plugged in but
not powered on). This is normal and is not a sign of
malfunction.
