Problem Possible Solution
There is no audio
from the center
and/or surround
speakers of a
home theater
receiver connected
to the QIP set-top
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
QIP set-top 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.
There is no video
on the TV screen
• Verify that the TV is powered on and set to the appropriate input source for
the QIP set-top.
• Verify that the QIP set-top is powered on and tuned to an authorized cable
channel.
• Verify that all video cables between the QIP set-top and the TV are firmly
connected.
• Verify that the coaxial cable feed is firmly connected to the QIP set-top and
the wall jack.
• If the QIP set-top 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 QIP set-top video output is connected to a TV through an HDMI
connection, power off the TV and then power off the QIP set-top. 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 QIP set-top. To select a different format:
1. Ensure that your QIP set-top is plugged into a power outlet and is turned
off.
2. Ensure the TV is turned on and tuned to the appropriate channel for the
set-top
3. Press the MENU key on the front panel. Your settings are displayed on
the QIP set-top front panel display.
4. Use the ▲ and ▼ keys on the front panel to display the HDMI/YPbPr
OUTPUT setting.
5. Press the ► key to cycle through the available output formats until a
picture displays on the TV.
No graphics or
program guides
appear on the TV
screen
If you use the IEEE-1394 connection, on-screen graphics, including closed
captions and program guides, are not displayed by the QIP set-top. On-
screen graphics and captions may still be overlaid by your TV, if enabled.
Alternatively, use HDMI or component video instead.
No closed captions
display
• Verify on the User Settings menu that closed captions are enabled on the
QIP set-top.
• Verify that closed captions are enabled on the TV.
Note: Closed captioning may not be available on the current program.
There are black
bars to the right
and left of the
picture
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 widescreen TVs to stretch the video to fill the screen (see your TV
manual for information about stretching 4:3 video).
• If the QIP7000 series is connected to a widescreen 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.
