Possible Solution
Verify that the TV is powered on and set to the appropriate input source for the
DCX set-top.
Verify that the DCX set-top is powered on and tuned to an authorized cable
channel.
Verify that all video cables between the DCX set-top and the TV are firmly
connected.
Verify that the coaxial cable feed is firmly connected to the DCX set-top and the
wall jack.
•
If the DCX set-top 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.
•
If the DCX set-top video output is connected to a TV through an HDMI™
connection, power off the TV and then power off the DCX set-top. Wait
one second and then power on the devices.
Not all HDTVs can display every output format (1080i, 720p, 480p, or 480i)
available on the DCX set-top. To select a different format:
1. Ensure that your DCX set-top is plugged into a power outlet and is turned
off.

the DCX set-top OSD.

If you use the IEEE-1394 connection, on-screen graphics, including closed
captions and program guides, are not displayed by the DCX set-top. On-screen
graphics and captions may still be overlaid by the TV, if enabled. Alternatively,
use HDMI™ or component video instead.
Verify on the User Settings menu that closed captions are enabled on the DCX
set-top.
Verify that closed captions are enabled on the TV.
Note: Closed captioning may not be available on the current program.
Widescreen 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
widescreen TVs to stretch the video to fill the screen (see the TV manual for
information about stretching 4:3 video).
•
If the DCX3200 is connected to a widescreen 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.
