The primary circuits in the AZ3G chassis consist of a Main Board (BAPS Board), Power Supply Board (G14/G15 Boards), the IR Board (HL Board), the 3D IR Emitter (HEM3 Board), the Wireless LAN Card, the Switch Unit, and the LCD Panel Assembly which includes the TCON Board and LD Board.
MAIN BOARD
Common to all models the Main Board, designated as the BAPS Board, contains the TV control, video and audio processing circuitry. All these functions are accomplished using the X-Reality Processor IC9000.
TUNER
The tuner is a combination analog/digital unit. It can receive traditional analog NTSC signals via cable or terrestrial along with digital SBTVD.
X-REALITY PROCESSOR
IC9000 performs the majority of the necessary audio and video processing on the Main Board.
TV Microprocessor: The CPU internal to the X-Reality processor controls all aspects of the television functions. Input from the user along with monitoring of critical circuits is also performed by this CPU.
Digital Audio and Video Decoder: The MPEG2 and Digital Dolby audio streams are received from the tuner for decompression. All video sources which are not native 1920 X 1080p 60HZ are scaled to this resolution.
Digital audio content is output to the class D amplifier for processing and amplification.
HDMI Input and Switching: The customer can select from the HDMI1through HDMI4 input via the HDMI switch IC5500. Each HDMI input contains a common EDI NVM (internal to IC5500) to provide display information data to any device connected via the HDMI inputs.
LVDS Transmitter: Integrated into IC9000 is a Low Voltage Differential Signaling (LVDS) transmitter. This circuit converts the 8-bit parallel RGB video information into a set of high speed serial lines for noise-free transmission to the TCON Board circuits located internally to the LCD Panel.
Scan Converter: Signal processing circuit that performs resolution conversion (aspect ratio) and interlaced to progressive scan (IP) conversion.
AUDIO AMPLIFIER
The main speaker audio amplifer (IC4601) and sub-woofer amplifier (IC4701) amplifies the digital audio output of the X-Reality Processor and sends it to the speakers.
TEMPERATURE SENSOR
The temperature sensor detects over-temperature conditions on the Main Board, LCD Panel or ambient room temperature and sends the shutdown signal to the processor.
POWER SUPPLY BOARD
The Power Supply Boards used in this model are:
G14 and G15 Boards
There are 3 distinct sections on the power supply:
Standby Supply: Continuously operational as long as AC power is applied, the standby supply generates 3.3V for the circuits requiring power while the unit is turned off. An unregulated 19V line is present to provide power to the main relay, PFC and main power supply at turn-on.
Main Supply: Once the power supply receives a power-on command from the CPU on the Main Board, the main switching supply is turned on to provide a regulated 12V source and Audio 12V.
Converter: Generates the B+ and B- voltages for the LED back-lights.

SELF
DIAGNOSIS FUNCTION
Critical voltages and circuit
operations are monitored by the CPU on the Main Board. If an error is detected
the Self Diagnosis function in the TV will force the TV to shut down by the
CPU. The monitored circuit in which the fault occurred will automatically cause
the CPU to blink the Standby LED in groups of repeating sequences. The number
of times the Standby LED blinks indicates the possible cause of the problem.
Not all of the available protect codes are used in every model. For example, models
that don’t have the local dimming feature do not use the 4X blink error as this
circuit is found in models that are backlit with fluorescent lamps.
The information in this section provides guidance in locating the possible component causing the shutdown.

2X Blink - Main Power Error
A loss of REG12V from the power supply triggers this protect event. The usual cause is a failure of the main switching supply. In some instances, excessive loading on the secondary supply lines can cause the switching regulator to stop or fail again, if a replacement board is installed.
3X Blink- DC Regulator/Audio Error/HDMI/Tuner
Several items are monitored on the Main Board. Any error detected in the following circuits will cause the television to shut down and generate a 3X error:
Loss of regulated B+ circuits
Audio amplifer failure
HDMI equalizer IC
Tuner demodulator circuits
In most cases, replacement of the Main Board will remedy a 3X error.
4X Blink – Balancer Error
The 4X error code is only used on models incorporating local dimming LED backlighting. If a failure occurs on the LD Board or one of the LED’s fails in the panel the TV will shut down and display this diagnostic code. Models using conventional non-local dimming LED backlighting do not utilize this error code.

7X Blink - Temperature Failure
If the temperature inside the television becomes excessive, the temperature sensor (located on the Main Board) notifies the TV to shut down and display a 7X error. Excessive temperature errors will always occur when the TV has been running a while and can be caused by excessive ambient heat or improper ventilation of the television.
8X Blink – Not listed in Self Check
The 8X blink code is mainly used during TV software development. Look in TV’s service Self Check for error code history and notice at the bottom of the list WDT (Watch Dog Timer) error codes, in particular notice 103 HOST_WDT. If this error code appears, check for any additional documentation on the Sony ESI site.
10X Blink – IR Sync Transmitter Failure
A failure of the infrared sync transmitter circuits on the HEM3 Board will cause a 10X error and replacement of this Board will usually rectify the problem. In rare cases, the Main Board could be the source of the failure.
SOFTWARE UPDATES FOR CUSTOMERS
The subject of software updates is very important. The televisions of today have advanced to the point where they are not simply a television anymore. They are evolving into devices that are designed to integrate with numerous other devices found in the home. Some examples are: portable audio and video devices, still cameras, home computer networks and accessing the internet to name a few.
Communications with these varying devices requires that the television be compatible with varying communications protocols. Although standards are detailed for each of these protocols, the real world dictates that occasional errors may occur that could prevent devices from operating or communicating properly.
Keeping the software in the television up-to-date is a procedure that is normally handled by the owner of the television. Most customers who own computers and other digital devices are familiar with and are accustomed to updating the software in their products. If a customer contacts the Sony Customer Support Center and it is deemed to be correctable with a software update, the issue is handled at the customer level.
Software updates can be performed
by:
Customer Manual Downloads
Software updates can be downloaded and placed on a USB thumb drive to be loaded onto the TV. The instructions for downloading the software fle vary from chassis to chassis and sometimes from model to model. The customer is provided with the instructions to properly format the USB thumb drive, unzip the fle and the procedures for loading the software into the television.
Network Downloads
Internet software updates are becoming more prevalent as more and more models incorporate home network capabilities. This method is the most practical since the
television will check for the latest version of software. The models with this type of chassis provide the customer with a choice of turning the automatic software update feature on or off. If set to on, the television will lookup software information while the unit is in standby. If a newer version is available, it will be downloaded and installed without any input from the customer.
Built-in Tuner
OTA or cable sources having the proper station that is transmitting software update data packets. Although the ability to transmit software update is possible in this way, it is the least common and is reserved for particular situations where a critical update is “forced”, thereby updating the TV without any input from the customer.
