3 INSTALLATION
Before You Begin
Before you move or change components on the subscriber’s entertainment system:
• Review the installation instructions.
• Determine if you are connecting to a standard analog NTSC TV (supporting an RF input), a composite (baseband) video input, or an S-Video input) or a High-Definition
TV (supporting component video input, HDMI input or an IEEE-1394 input).
• Determine if the subscriber has other equipment to be connected to the terminal
(home theater or A/V receiver, VCR, etc.)
• Verify that you have the necessary cables and other required items.
• If the terminal was previously used, clear its hard drive before installing it at a new subscriber location
Video Connection Options
Use the following guidelines to determine the best video connection for the subscriber home entertainment system. To determine the available video inputs on the TV, check the manual supplied with the TV or the TV itself.
The DCH3200 offers the following video outputs:
Component
(YPbPr)
HDMI or
IEEE-1394
HDTV and
SDTV
HDTV and
SDTV
The YPbPr outputs provide component video, the most widely supported
HD video connection.
HDMI and IEEE-1394 offer higher-quality HD video than component video.
If the TV has an HDMI or a DVI input, use the HDMI output instead of the
IEEE-1394 output.
HDMI and IEEE-1394 are video and audio connections. If you use HDMI or
IEEE-1394, no separate audio connection to the TV is required.
HDMI is compatible with DVI. If the TV has a DVI input, you can use an
HDMI-to-DVI converter cable or adapter to connect to the DCH3200 HDMI connector.
If you use IEEE-1394, on-screen graphics do not display.
S-Video
Video
(composite)
SDTV only If your TV does not have an S-Video input, use the composite video (video) output.
RF
SDTV only If your TV has an S-Video input, use S-Video. S-Video is the highest- quality standard-definition video output on the DCH3200.
SDTV only If your TV only has a coaxial RF input, connect it to the DCH3200 RF out connector.
9
3 INSTALLATION
Audio Connection Options
When connecting to a home theater receiver, depending on its inputs, you can use the following DCH3200 audio outputs:
Digital audio optical
(S/PDIF) or digital audio coaxial (S/PDIF)
If the receiver supports it, use the digital audio optical (S/PDIF) or digital audio coaxial (S/PDIF) audio output to deliver Dolby AC-3 audio to a Dolby
Digital home theater receiver.
•
For an HDMI or IEEE-1394 video connection, no additional audio connections to the TV are required.
•
For RF output, no further audio connection is required.
Baseband Audio L and R
If the audio receiver does not support Dolby Digital, use the baseband
AUDIO L and R outputs to connect to the audio receiver.
Connect the stereo audio cable to the AUDIO L and R connectors on the DCH3200 and the audio left and right connectors on the TV. If the equipment supports it, use the optical SPDIF or coaxial digital SPDIF output instead of the AUDIO L and R outputs. In most cases, these outputs offer better audio quality, including support for 5.1 Surround
Sound.
The cabling diagrams show sample audio/video (A/V) connections to an audio receiver, where the receiver functions as an A/V router. When connecting to an audio receiver, reference its installation instructions for directions on connecting to baseband and digital audio (S/PDIF) ports.
The VCR and TV receive their A/V signals from the currently selected input device on the audio receiver. This is important when the subscriber has another A/V device such as a
DVD player, a secondary VCR, a CD player, or other electronic component. We recommend connecting the TV to the monitor output so on-screen menus for the receiver can be displayed. (In many cases, the receivers themselves have interactive on-screen menus.)
Installation Overview
1.
Determine if you are connecting to a:
High-Definition
TV or monitor
Standard
Definition TV
Use the component video (YPbPr), HDMI, or IEEE-1394 outputs. No other video connection supports HDTV.
If your TV has a DVI input, connect a DVI-to-HDMI adapter or cable to the HDMI out connector on the DCH receiver instead of the IEEE-1394 connection, and the
DVI-HDTV connector on your TV.
Connect the S-Video connector using an S-video cable or connect the composite video connector using a composite (RCA phono) cable. If the TV only has a coaxial
RF input, connect it to the DCH3200 RF OUT connector.
2.
Determine if you are connecting the audio to a home theater receiver or directly to the TV:
•
For an HDMI or IEEE-1394 video connection, no additional audio connections to the TV are required.
•
If the receiver or TV has a digital audio (S/PDIF) input, use the digital audio
OPTICAL (S/PDIF)
or
COAXIAL (S/PDIF)
outputs.
10
3 INSTALLATION
•
Otherwise, use the baseband left and right audio out outputs.
3.
Locate the cabling diagram(s) that best match the subscriber’s configuration.
4.
Connect the audio and video cables in a manner matching that diagram.
5.
Determine if you are connecting to a data device (see
in this section). For installation details, refer to the instructions included with the data device.
6.
Connect the cable terminal to the coaxial cable wall outlet.
7.
Perform the operational check for the remote control.

3 INSTALLATION
Cabling to an HDTV for Video
For the best possible HDTV video quality:
• If the TV has an HDMI input, connect it to the DCH3200 HDMI output. If the TV has a DVI input, you can connect it to the DCH3200 HDMI output using and HDMI-to-
DVI converter cable or adapter.
• If the TV has neither an HDMI nor a DVI input but has an IEEE-1394 input, connect it to the DCH3200 IEEE-1394 output. If you use IEEE-1394, on-screen graphics do not display.
• Otherwise, use the component video (Y, Pb, and Pr) connectors.
Note: Be sure to match up each signal to the same connection on the TV. Otherwise,
the colors will not appear correctly on your TV.
Figure 3-1 Cabling to an HDTV

Because HDMI and IEEE-1394 provide both video and audio output, no additional audio connections to the TV are required if you use either of these connections.
3 INSTALLATION
Cabling to an HDTV and an A/V Receiver
Figure 3-2 Cabling to an HDTV and an A/V receiver
If the receiver can check the baseband and digital audio (S/PDIF) ports for appropriate channels, connect both the baseband and digital audio connections. Otherwise, do not connect both the baseband left/right composite connections and the coaxial digital connection. The baseband connections are not necessary because the digital audio port provides a single audio interface for digital channels.
Note: If the A/V receiver includes HDMI inputs & output(s) then the DCH3200 HDMI output can be directly connected to the A/V receiver.

The list displays all of the formats that the DCH3200 could read, up to a maximum of 12 formats. If the DCH3200 cannot read any formats, EDID Data is blank. An asterisk (*) after the aspect ratio means the DCH3200 supports the format. If more than twelve video timing formats are discovered, the supported formats only are listed first, followed by up to twelve remaining formats.

5 TROUBLESHOOTING
Troubleshooting guidelines follow. If problems still occur after performing the diagnostics, call the TRC for assistance as described in the Introduction.
The DCH receiver will not power on
The remote control does not work
There is no audio when viewing cable channels
There is no audio from the center and/or surround speakers of a home theater receiver connected to the DCH receiver
There is no video on the TV screen
The DCH receiver may have received a software update and may not power on while the new software is being installed. Try again in a few minutes.
•
Verify that the AC power cord is connected to the DCH receiver and an AC outlet. Unplug the DCH receiver from the AC outlet, plug it back in, and then press the POWER button.
•

•
Press the POWER button on the DCH receiver’s front panel instead of the remote control. The batteries in the remote control may be depleted.
•
Verify that the remote control is in “Cable” mode.
•
Verify that there are no obstructions between the remote control and the DCH receiver. Aim the remote control directly at the DCH receiver front panel, not the
TV or VCR.
The angle between the remote control and the DCH receiver may be too large. Stand in front of the DCH receiver and not too far to either side.
•
Press and release operation keys one at a time, firmly and deliberately.
•
Try changing channels using the buttons on the DCH receiver front panel.
•
Check the batteries in the remote control. Install new batteries if needed.
•
Verify that the mute button on the DCH receiver or the remote control has not been pressed. Press MUTE on the remote control to restore sound.
•
If the DCH receiver audio output is connected to the TV, verify that the mute button on the TV has not been pressed.
•
If the DCH receiver audio output is connected to a home theater receiver, verify that the receiver is set to the appropriate input source and the mute button on the receiver has not been pressed.
•
Verify that you have the correct cables for the audio connections.
•
Verify that the audio cables are firmly connected between the DCH receiver and the audio playback device (TV, receiver, DVD player, etc.).
Not all Dolby
®
Digital programs feature full 5.1 surround sound. In some cases, the programs may only contain left and right stereo audio.
•
Verify that the S/PDIF cable (coaxial or optical) is firmly connected to the DCH receiver and the home theater receiver.
•
Verify that the home theater receiver is set to a surround sound audio mode
(Dolby Digital, Dolby Pro Logic II
®
, Dolby Pro Logic
®
).
•
Verify that the receiver is properly configured to work with all connected speakers.
•
Verify that the TV is powered on and set to the appropriate input source for the
DCH receiver.
•
Verify that the DCH receiver is powered on and tuned to an authorized cable channel.
•
Verify that all video cables between the DCH receiver and the TV are firmly

No graphics or program guides appear on the TV screen
No closed captions display
There are black bars to the right and left of the picture
There are black bars above and below the picture
connected.
•
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.
Note: Closed captioning may not be available on the current program.
Wide screen 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 DCH3200 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 DCH3200 is tuned to a 4:3 program.
•
Set the TV TYPE to 4:3 Pan-Scan. This enables the DCH3200 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 wide screens 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).
60
5 TROUBLESHOOTING
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 DCH3200 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.
Colors do not appear correctly
