Overview

This chapter provides a high-level overall block view of the AX-1 chassis PCB interconnects and the functions

performed on each PCB.

Figure 1-1 provides a schematic type diagram showing how all the PCBs are interconnected within the complete

system. Also shown is a brief list of the functions performed on each PCB.

For further details concerning the functions performed on each PCB, reference Table 1-1. This table provides a

detailed list of the circuits located on each PCB in the column label circuits.

Inthecolumnlabeled“BoardReplacementAdjustments”isalistofadjustmentsthatmustbecheckedorperformed

when that particular board is replaced.

The column label “Comments” provides repair comments, such as, if the particular board can be removed from

the unit and if the unit will remain powered for troubleshooting, and what symptoms are to be expected when the

board is removed.

Both Figure 1-1 and Table 1-1 are excellent troubleshooting tools that allow the technician to quickly get to the

area they need to be troubleshooting when a defect occurs.

CONVERGENCE PATTERN

Manual Convergence

This feature allows the end-user to make point-by-point (Fine) convergence (ref. Figure 2-1) adjustment using

theremote control. Before this featurecan be accessed, theFlash Focus feature mustbe performed. The Flash

Focus does not set the convergence settings back to factory settings; this is performed through the Reset

function.

There is no USER copy function so the end-user must make their adjustments in each screen mode (Full/

Normal, Zoom, Wide Zoom, Memory Stick/High Definition inputs).

For optimal adjustment, the following pre-adjustment steps are recommended:

Allow the unit to warm up for 30 minutes before adjustment.

Set the Mode to “Pro” or “Movie”.

Lower Picture Level (eliminate any flaring along cross edges).

Stand back approximately three to five feet when making adjustment.

Note: Press reset to set Mode and Picture back to original settings.

Note: If AC power is removed, Flash Focus must be performed again to access Manual Convergence.

DigitalVisualInterface(DVI)

Introduction

As the digital display technology (e.g. Plasma and LCD) grows, so does the need to replace the present

analog HD component connection between external digital device (e.g. Digital TV/Satellite Receiver) and the

HDTV set. The issue is the inherent picture quality problems caused by Digital-to Analog (D/A) and Analog-to-

Digital (A/D) conversion processes.

For example, if you have a digital Plasma Display HDTV and a Digital TV/Satellite Receiver, the digital video

signal in the Digital TV/Satellite Receiver must be converted to an analog component video signal and then

sent to the HDTV where it must be converted back to a digital signal video to drive the Plasma display.

Because of the two video signals conversion steps and the possible analog signal loss across the connection

between the HDTV and the Digital TV/Satellite Receiver, the picture quality will suffer. Even with an analog

CRT the Digital TV/Satellite Receiver, video signal must go through D/A conversion, which can adversely

affect picture quality.

EDID

HDCP

The resolution to this dilemma is the creation of a complete end-to-end standard digital video interface, ala DVI.

The DVI interface is a high-speed digital video interface allowing uncompressed high-definition content to be

passed to another DVI equipped device such as an HDTV set. DVI is the only digital interface capable of

accommodating uncompressed digital data such as HD video. DVI also has the bandwidth to support higher

audio fidelity.

DVI has a bandwidth of up to 5 Gigabits/sec, which is more then enough to accommodate an uncompressed HD

video transmission typically requiring 2.2 Gigabits/sec bandwidth.

DVI Connector and Decoding Block

Ref. Figure 2-2

The DVI Molex connector and Decoding circuitry for the AX-1 chassis are located on the UD-Board (NOTE: This

board is NOT field repairable). Figure 2-2 shows a block diagram for the UD-Board. The DVI signal (from a

Digital TV/Satellite Receiver) is received at the 24-pin Molex connector CN7001. There are three serial data

differential channels RX0+/RX0-, RX1+/RX1-, RX2+/RX2- and one reference clock differential channel RXC+/

RXC-.

IC7001 NVM is also connected to the external device through the SDA and SCL (I2C) bus. IC7001 stores the

EDID (Extended Display Identification Data).

EDID is sent to inform the STB or external digital device of the TV’s identity and capabilities.

HDCP is an Authentication protocol between the external digital device (transmitter) and the TV (receiver) that

affirms to the transmitter that the receiver is authorized to receive the protected digital video information.

CN 7001/pin 14 (5V) is supplied from the external digital device to power IC7001 (NVM) so EDID can be sent

when the TV set is OFF. If the TV set is ON, IC7001 will receive 5V from CN7002 through D7001.

CN7001/pin 16 is the Hot Plug Detect pin (HPD). The TV set supplies 5V to the external digital device to verify

proper connection between the two devices.

PCM

The DVI Decoder, IC7004 receives the three channels of digital video data and outputs analog component video

(Y, PB, PR) to CN7002/pins 10, 8 and 6 respectively.

Q-Box

The Q-Box processes ATSC (off-the-air digital broadcast) broadcast, Memory Stick and I-Link signals. The

boardsincluded in the Q-Boxare the QM, QIandQT. The QM performsallQ-Module video andaudioprocessing.

The QI board is the I-Link interface and the QT is the “off-the-air” or terrestrial (from antenna switch) signal

interface. The Memory Stick feature uses an external interface board QH, which is connected to the Q-Box via

USB cable.

The Q-Box outputs the 1080i signal format for all selected inputs.

The Q-Box is replaced as an assembly (including QM, QI, and QT boards) if found defective.

The following text and diagrams will help in troubleshooting and determine a possible defective Q-Box. Figure 2-

3 is a block diagram showing all the external connections to the Q-Box.

The Q-Box processes the following digital signals:

HDTV Terrestrial Signal (RF)

Memory Stick Images or Movies

I-Link Data

The digital signals are processed and D/A converted by the Q-Box processor on the QM board. The Component

Video (Y/PB/PR) and Audio (LT/RT) analog signals are then output to the UA (AV Switcher). Digital audio is also

output from the Q-Box on the rear (Digital Optical connector) of the unit in PCM/Dolby Digital format.
