5 TROUBLESHOOTING
Problem
There are black bars
on all four sides of the
picture
Colors do not appear
correctly
The DCH receiver is
making a humming
noise.
Possible Solution
This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is OFF. To set 4:3 SD
programming to fill the screen, depending on the capabilities of the TV, set
4:3 OVERRIDE to 480i or 480p.
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 widescreen 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 DCH3416 cannot correct the video. You
may be able to minimize the border using the zoom feature on the TV.
Be sure to match up each signal to the same YPbPr connection on the TV. Otherwise,
colors will not appear correctly on your TV.
The DCH3416 includes an integrated hard drive and a fan for cooling. During normal
operation, the DCH3416 emits a low humming noise, similar to a personal computer. The
noise varies in volume occasionally when the speed of the internal fan adjusts to changes
in the temperature around the DCH receiver. Please note the hard drive will stay on even
when the DCH3416 is turned off (standby).
