This handbook covers 3 pins power detect switches, power driver, buffer IC, power, LDO IC, 8 – 16 pins power buck chips, main board interfaces, various voltage test points and memory chips which fail quite often and will require replacement and software programming to troubleshoot properly.
This E-book will comprehensively teach and guide you everything you need to know about LCD/LED/PLASMA TV Main board Repair, from intermediate level right through to being a professional troubleshooter
Lots of TV repairer when faced with problem on LCD/LED/PLASMA TV Main Board, will just do some easy troubleshooting on it and then just replace a whole boards. They give up easily with troubleshooting or voltage testing. And their reason sometimes would be its stressful and time consuming, which is saying it’s hard to repair; I don't know where to start testing from! Or how to isolate the problem and so on!

Bonus 2
EEPROM IC FAILURE
EEPROM IC is used to store or save data setting on the T-CON Board and it also serves as an I2C interface TCON IC, GAMMA AND DCP IC. Sometimes when all screen image is colorless or with hue of green/red pale, the fault is from NVM EEPROM, Replace it, with another one, write it before solder TV will turn out find.
To store the gamma and the VCOM values, an external EEPROM is required. During power-up of the LCD panel, the timing controller can then read the EEPROM and load the values into the Buffer IC to generate the desired gamma voltages as well as VCOM voltages.
Just like BIOS when this EEPROM gets corrupt it causes white screen display, abnormal color display, or no display at all.
Available to you are Collection of All T-CON EEPROM Dump/Firmware for your future Repairs.
eMMC failure
eMMC failure could be as a result of firmware or hardware problem. For firmware problem usually due to internal error that occur as a result of bad block/sector, while could be hardware problem due to components & circuit line problem, including their loop holes problem or dry soldering point which will sometimes need to be reflow.
For the eMMC chip, use the Universal Programmer to reador write this IC, you can use offline method (use an adapter) or flying wires to their DO, DI, CLK, GND & Vcclines (Refer to their eMMC chip pins).
Available to you here are Collection of Emmc pin-out.
