Some channels may not have caption data.
The picture is distorted.
The compression of the video content may cause picture distortions. This is especially true
with fast moving pictures from sports programs and action movies.
A weak signal can cause picture distortions. This is not a problem with the TV.
The picture quality is low. Select high definition (HD) channels or programs.
My Computer Won't Connect

The problem Try this!
The "Mode Not Supported"
message appears.
Set your PC’s output resolution so it matches a resolution supported by the TV.
The video is OK but there is
no audio.
If you are using an HDMI connection, check the audio output setting on your PC.
If you are using an HDMI-to-DVI cable, a separate audio cable is required. Note that the
HDMI-to-DVI connection is only supported by the HDMI (DVI) port and does not transmit
audio. To listen to the computer sound, connect external speakers to the audio output
connection of the computer.
