Problem Possible Solution

There is no audio

from the center

and/or surround

speakers of a home

theater receiver

connected to the

IPC1100 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

IPC1100 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.

on the TV screen

• Verify that the TV is powered on and set to the appropriate input source for

the IPC1100 set-top.

• Verify that the IPC1100 set-top is powered on and tuned to an authorized

cable channel.

• Verify that all video cables between the IPC1100 set-top and the TV are firmly

connected.

• Verify that the coaxial cable feed is firmly connected to the IPC1100 set-top

and the wall jack.

• If the IPC1100 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 IPC1100 set-top video output is connected to a TV through an HDMI

connection, power off the TV and then power off the IPC1100 set-top. Wait

one second and then power on the devices.

Not all HDTVs can display every output format (1080i, 1080p, 720p, 480p, or 480i)

available on the IPC1100 set-top. To select a different format:

1. Ensure that your IPC1100 set-top is plugged into a power outlet and is

turned off.

2. Ensure that the TV is turned on and tuned to the appropriate channel for the

set-top

3. Press the MENU key on the remote control. Your settings are displayed on

the IPC1100 set-top front panel display.

OUTPUT setting.

displays on the TV.

Widescreen TVs display 4:3 programs in this format unless set to Stretch. Setthe

4:3 STRETCH 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 IPC1100 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.
