Problem Possible Solution
There are black bars on
all four sides of the
picture
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 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 DCH3416 cannot correct the video.
You may be able to minimize the border using the zoom feature on the TV.
Colors do not appear
correctly
Be sure to match up each signal to the same YPbPr connection on the TV, otherwise
the colors will not appear correctly on your TV.
The DCH receiver is
making a humming
noise.
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).
