Possible Solution
•
Verify that the coaxial cable feed is firmly connected to the DCH receiver and
the wall jack.
•
If the DCH receiver 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 DCH receiver video output is connected to a TV through an HDMI
connection, power off the TV and then power off the DCH receiver. 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 DCH receiver. To select a different format:
•
Ensure that your DCH receiver is plugged into a power outlet and is turned
off.
•
Press the MENU key on the front panel. Your settings are displayed on the
DCH receiver front panel display.
•
Press the ▲ and ▼ keys to display the HDMI/YPbPr OUTPUT setting.
•
Press the ► key to cycle through the available output formats until a picture
displays on the TV.
If you use the IEEE-1394 connection, on-screen graphics, including closed captions
and program guides, are not displayed by the DCH receiver. On-screen graphics and
captions may still be overlaid by your TV, if enabled. Alternatively, use HDMI or
component video instead.
•
Verify on the User Settings menu that closed captions are enabled on the
DCH receiver.
•
Verify that closed captions are enabled on the TV.
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 wide screen
TVs to stretch the video to fill the screen (see your TV manual for information about
stretching 4:3 video).
•
If the DCH6416 is connected to a wide screen 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.
All 4:3 HDTVs display HD programs in letterbox format (black bars above and below
the picture) because of the shape of the display screen.
•
Turn on the 4:3 OVERRIDE feature in the User Settings menu. This enables
most standard screen TVs to display a full screen picture when the DCH6416
is tuned to a 4:3 program.
•
Set the TV TYPE to 4:3 Pan-Scan. This enables the DCH6416 to remove the
black bars above and below the picture when possible.
Some SD programs are broadcast in the letterbox format with black bars above and
below the picture. Some widescreen TVs offer a zoom feature that may be able to
remove the black bars (see your TV manual for information about zooming 4:3 video).
