6 TROUBLESHOOTING
Problem
There are black
bars on all four
sides of the
picture.
Possible Solutions
•
This may occur on a 16:9 TV if the active
video for an SD broadcast is in letterbox
format. To confirm, wait for a commercial or
look for a graphic, such as a network logo.
If the commercial fills the screen from top
to bottom, or the graphic appears below
the active video, the program is being
letterboxed by the broadcaster. You can
minimize this by activating the zoom
feature on the TV.
•
A broadcaster may include black bars on
either side of a wide screen broadcast. This
is called a "hybrid" aspect ratio and results
in a black border surrounding the video on a
4:3 TV. Because this is part of the
broadcast, the DCH100 cannot correct the
video. You may be able to minimize the
border using the zoom feature on the TV.
