10 - 15 minutes if there is no signal.
There is no picture/video.
• Check the cable connections. (Remove and reconnect all cables connected to
the TV and external devices).
• Set your external device’s (Cable/Sat Box, DVD, Blu-ray etc) video outputs to
match the connections to the TV input. For example, if an external device’s
output is HDMI, it should be connected to an HDMI input on the TV.
• Make sure your connected devices are powered on.

SOURCE
button on the

Antenna (Air / Cable) Connection
The TV is not receiving all
channels.
• Make sure the coaxial cable is connected securely.
• Run
Auto Program
to add available channels to the channel list. There are 3
options,
STD, HRC
and
IRC
. Most cable systems use
STD
.
• Verify the antenna is positioned correctly.
No Caption on digital channels.
• Check the
Caption
Setup menu. Try changing
Caption Mode Service1
to
CC1
.
• Some channels may not have caption data.
The picture is distorted:
macroblock, error, small block,
dots, pixelization.
• The compression of video contents may cause picture distortion, especially in
programs with fast moving pictures such as sports programs and action movies.
• A weak signal can cause picture distortion. This is not a TV problem.
Others
Purple/green rolling horizontal
bars and buzzing noise from the
TV speakers with Component
cable connection.
• Remove the left and right audio connections from the set-top-box. If the
buzzing stops, this indicates that the set-top-box has a grounding issue. Replace
the Component video cables with an HDMI connection.
Plasma TV is making humming
noise.
• Plasma TVs typically make a soft humming sound. This is normal. It’s caused by
the electrical charges that are used to create the images on the screen.
• If the humming sound is loud, you may have set the brightness on the TV too
high. Try setting the brightness lower.
• You can also have loud humming if the back of your Plasma TV is too close to a
wall or other hard surface. Also try rerouting your connection cables.
• Improper installation of the wall mount can create excessive noise.
