DCT6200\DCT6208 Installation Manual
Possible Solutions
Verify that the TV is powered on and set to the appropriate input source for the
DCT*.
Verify that the DCT* is powered on and tuned to an authorized cable channel.
Verify that the coaxial cable feed is firmly connected to the DCT* and the wall
jack.
The DCT* DVI output may not yet be enabled. Use the component video
(Y Pb Pr) output instead.
If the DCT* video output is connected to a home theater unit, verify that the
home theater unit is powered on and set to the appropriate input source.
Not all HDTVs can display every output format (1080i, 720p, 480p, or 480i)
available on the DCT*. Enter the User Settings menu and cycle through the
available output formats until a picture displays on the TV.
Verify that all video cables between the DCT* and the TV are firmly connected.
The DCT* cannot generate graphics on all video outputs at all times. If the
DCT* is set to 1080i, 720p, or 480p output format, graphics are only available
on the high definition video outputs (DVI and component video). If the DCT* is
set to 480i, graphics are available on all video outputs. For more information,
see "Graphics Overlaying the Video" in Section 3, "Installation."
If the DCT* is connected to a standard definition (SD) TV, verify that the DCT* is
configured to use the 480i output mode.
Verify that closed captions on the DCT* have been enabled in the User Settings
menu.
Wide screen TVs display 4:3 programs in this format unless set to Stretch. Turn
on the 4:3 OVERRIDE feature in the User Settings menu. This enables most
wide screen TVs to stretch the video to fill the screen (see the TV manual for
information about stretching 4:3 video).
If the DCT* is connected to a wide screen TV, verify that the TV TYPE is set to
16:9 in the User Settings menu.
Many HD programs are broadcast in pillar-box format with black bars to the left
and right of the picture. These programs are broadcast in 16:9 HD formats even
though the video is not 16:9.
All 4:3 HDTVs display HD programs in letterbox format (black bars above and
below the picture) because of the shape of the display screen.
Turn on the 4:3 OVERRIDE feature in the User Settings menu. This enables
most standard screen TVs to display a full screen picture when the DCT* is
tuned to a 4:3 program.
Set the TV TYPE to 4:3 Pan-Scan. This enables the DCT* to remove the black
bars above and below the picture when possible.
Some SD programs are broadcast in the letterbox format with black bars above
and below the picture. Some wide screens TVs offer a zoom feature that may
be able to remove the black bars (see the TV manual for information about
zooming 4:3 video).
