Objective
The newly introduced High Definition Projection Televisions, P9 Series,
accommodate the 480i, 480p, and the 1080i Digital TV formats. They also
function as complete NTSC TV receivers. Some of the models contain a digital
tuner that allows the reception of digital TV broadcast as well as digital cable
television, eliminating the use of a Set Top Box. Furthermore the digital tuner
incorporates the OpenCable technology that interfaces between the cable
service provider and the customer for subscription purposes. The High End
models contain a PhotoViewerTM that allows the viewing of digital pictures taken
with a digital camera.
The information provided in this document is designed to assist the technician in
determining the defective component or board while performing repair. The
troubleshooting flowcharts, signal path diagrams and connector information
should provide enough detail so that the technician can accurately determine
which component or board is required to repair the product.

New Features
Digital tuner
Built in Set Top Box
The built in Set Top Box is designed to receive NTSC and ATSC television
broadcast. The ATSC reception includes High Definition TV (HDTV) and
Standard Definition TV (SDTV). Each consists of many formats. The well-known
NTSC system is not included among the DTV formats. DTV is based on a new
set of standards developed by the Advanced Television Systems Committee
(ATSC). All formats used in digital TV exhibit a highly improved picture quality in
conjunction with five channels of CD quality audio and one low frequency effects
(LFE) channel. This new digital tuner also provides the NTSC video output for the
main picture. It is a hybrid tuner that processes NTSC and ATSC terrestrial
broadcast for reproduction on the TV screen. DTV transmission started in the fall
of 1998. A total transition to DTV is to be completed by 2007.
ATSC (Advanced Television System Committee) is the organization that governs
digital television terrestrial broadcasting. The television broadcast is in
digital form requiring the use of a digital TV tuner.
OpenCable - Cable digital is a concerted effort by North American cable
operators to:
• Provide next-generation digital cable-ready devices;
• Encourage supplier competition;
• Create a common platform for advanced interactive cable services; and
• Create a retail hardware platform.
One of the OpenCable project's goals has been to standardize the cable network
interface, which will help to enable a retail market for competitively priced digital
cable products (e.g., integrated DTV’s, set-top boxes). As part of this effort, the
OpenCable specifications define an interface to a removable CableCARD™
module that separates the cable operator's proprietary conditional access system
from the retail digital cable device (a "host"), thereby enabling portability of the
host to other cable networks.
The OpenCable project has developed two key sets of specifications: one for
hardware components, and one for software components.
The hardware specifications allow a digital cable product that is sold at retail to
provide portability. It includes specifications for a host device, a copy protection
system including security and user authentication, and a CableCARD
module/host interface. This means that if a consumer purchases a set-top box or
an integrated DTV in New York and then relocates to Los Angeles, that set-top-
box or integrated DTV will be operational with the new regional cable provider's
equipment.
6

The software component of the OpenCable project is called the OpenCable
Applications Platform (OCAP™) specification. OCAP provides an open interface
between the manufacturer's operating system and the various applications that
will run within the host. This open interface will accelerate application
development and deployment of new interactive television (iTV) services.
Currently, developers of iTV applications and services must rewrite their
programming for each proprietary host platform upon which the applications and
services will run. OCAP addresses this challenge by providing a standard set of
application programming interfaces (APIs), so that any application may be
deployed across the full range of OpenCable host devices. Retail manufacturers
who build OpenCable devices may be assured that their devices will run any
applications that run on comparable set-top boxes leased by cable operators
directly to their customers. These applications may include:
Electronic program guides (EPGs);
Impulse pay-per-view (IPPV);
Video-on-demand (VOD);
Interactive sports, game shows;
Web access features such as e-mail, chat, instant messaging;
Interactive games and services such as shopping (television commerce, or "T-
Commerce"), home banking, and personal video recorders (PVR).
Clear Digital Picture - The unit incorporates a cable-ready tuner that allows
cable subscribers to receive crisp digital TV signals without the need of a set-top
box. It would also tune in over-the-air broadcasts for the handful of consumers
who use rooftop antennas.
Multiple Programs in 6MHz band - the allocated bandwidth for DTV
transmission is at 6MHz. SD (Standard Definition) broadcast occupies much less
space in the 6MHz bandwidth allocated for DTV broadcast. This results in the
broadcast of up to six different programs per channel making terrestrial TV
transmission more competitive than cable.
High Definition Program - High definition programming such as 720p and,
1080i occupies much of the 6MHz bandwidth allocated for DTV transmission.
This results in the broadcast of only one program per transmission. Although
extensive compression techniques are used to reduce the content of the
program, the high resolution and high frequency components of the high
definition signal does not allow the broadcast of additional programs.

Cable Module Info
This menu is used to provide information when a DCM (Digital Cable Module) is
inserted into the DCM INTERFACE (POD INTERFACE) slot on the back of the
projection television. If no DCM is present and you try to access the Cable
Module Info, the message ‘Cable Module Not present’ will be displayed on the
screen. To receive the features offered by your cable company, you may have to
subscribe to those services.
Note: Please contact your cable company regarding the availability of the
DCM (Digital Cable Module). The cable module is needed to receive premium
digital services (where available) through the cable input. You may also be
able to order call-ahead pay per view events.
