II. reset circuitry working normal. III. Crystal working normal IV. SCL and SDA working normal and so on.

Part II. Reset Section

Each time turn on the TV, after power supply loading, the reset circuitry is working, Pin205 of U8 is high level durative about 40ms, then finished the TV reset. It is low level under normal situation. While the 3.3V voltage is loading, charge on C74 and C80, due to the resistance of D40 is smaller than R32, so the voltage on C74 will higher than C80, Q8 turnon, the current passes Q8,Pin205 of U8 get high level. As the voltage charge on C80 fully, Q8 cut-off, finished the TV reset.

Part III. Tuner Section

The phone audio signal output from Pin71/Pin 71,through the integral circuitry R34/R36/C37 and R47/R51/C83 send to U16 and output from P17.

Part VI HDMI EDID Introduction

Extended display identification data (EDID) is a data structure provided by a computer display to describe its capabilities to a graphics card. It is what enables a modern personal computer to know what kind of monitor is connected. EDID is defined by a standard published by the Video Electronics Standards Association (VESA). The EDID includes manufacturer name, product type, phosphor or filter type, timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping data.

The channel for transmitting the EDID from the display to the graphics card is usually the I2C bus. The combination of EDID and I²C is called the Display Data Channel version 2, or DDC2. The 2 distinguishes it from VESA's original DDC, which used a different serial format.

Before DDC and EDID were defined, there was no standard way for a graphics card to know what kind of display device it was connected to. Some VGA connectors in personal computers provided a basic form of identification by connecting one, two or three pins to ground, but this coding was not standardized.

The EDID is often stored in the monitor in a memory device called a serial PROM (programmable read-only memory) or EEPROM (electrically erasable PROM) that is compatible with the I²C bus.

VGA EDID OR DDC

PART VII HDCP Section

High-bandwidth Digital Content Protection (HDCP) is a form of Digital Rights Management (DRM) developed by Intel Corporation to control digital audio and video content as it travels across Digital Visual Interface (DVI) or High-Definition Multimedia Interface (HDMI) connections. The specification is proprietary, and creating an implementation of HDCP requires a license .HDCP is licensed by Digital Content Protection, a subsidiary of Intel. In addition to paying fees, licensees agree to limit the capabilities of their products. For example, high-definition digital video content must be restricted to DVD quality on non-HDCP compliant video outputs when requested by the source. DVD-Audio content is restricted to DAT quality on non-HDCP digital audio outputs (analog audio outputs have no quality limits). Licensees cannot allow their devices to make copies of content, and must design their products in ways that "effectively frustrate attempts to defeat the content protection requirements."

Each HDCP capable device has a unique set of keys; there are 40 keys, each 56 bits long. These keys are confidential and failure to keep them secret may be seen as a violation of the license agreement. For each set of keys a special key called a KSV (Key Selection Vector) is created. Each KSV has exactly 20 bits set to 0 and 20 bits set to 1.

During the authentication process, both parties exchange their KSVs. Then each device adds (without overflow) its own secret keys together according to a KSV received from another device. If a particular bit in the vector is set to 1, then the corresponding secret key is used in the addition, otherwise it is ignored. Keys and KSVs are generated in such a way that during this process both devices get the same 56 bit number as a result. That number is later used in the encryption process.As result that, this chassis adopts 24C04 to storage KSV and license makes digital signal resource output.

PART VIII EEPROM for Software

It adopts Winbond company’s W25X40 flash which has 4M-bit/526 bytes and 2048pages.It is used for storage the main system software. The devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 5mA active and 1uA for power-down.。

EEPROM for User Information

It adopts I

C compatible electrically erasable programmable memory (EEPROM) devices are organized as 4096x8 bits(32k).This is a two-wire series interface that uses a bi-directional data bus and serial clock. It is used for storage user’s information, such as channel search and timer on and off, and picture standard and other information what user’s easy to change by local key board and remote control.

PART IX Panel ON/OFF Control Section

While the TV is turn on, the TV is standby situation. While command turn on is send out, 5v voltage will through regulator and equal get 3.3V voltage or 1.8V voltage supply for U8. After reset and crystal Y1 working, the main system software will be loaded, the panel –ON/OFF command will be sent out, makes the dual-MOSFET U3 turn on and send 5V/12V/3.3V voltage to the panel.

The following figure is showing the power sequence and control signal timing.
