5 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 DCH70 cannot correct the video. You
may be able to minimize the border using the zoom
feature on the TV.
