Firmware tested in DTV module 1-869-656-12 and 1-869-656-21.
Content of NAND flash Hynix HY27US08281A TSOP48. File is Elnec project type with complete content and chip programmer settings (PG4UW version V3.17C/09.2015), compatible also with Elnec BeeProg+.
If you need also content of NAND flash Hynix H27U1G8F2BTR TSOP48, contact me, because lenght of file is very big.
I use Elnec chip programer BeeHive4+ (BeeProg+) with program for Windows PG4UW V3.17c/09.2015, so NAND content is compressed in .prj (project) file with lenght aprox. 85MB also with settings of chip programer - Thank you Maxim I not use .BIN format, because is not reliable (without crc checksum).
Description of repair: CPU BGA LGE2111 is burned with surge voltage via HDMI input. After replace of CPU, TV is fully working.
Description of malfunction: TV Sony KDL-32S3000 have inverse colors. Bad U8 AS34-G (EC5534) 14pin smd package TSSOP-14. I use substitute IC AD8567A from broken 19" LCD panel CHIMEI M190E2 L01 Rev.C1. Other substitutes: HX8904TA, HX8904TB, 5420CR, i7514HS, EL5411
Supply voltage of U8 and U7 is 15.5V
Main supply voltage of TCON is 12V
U7 EC48324 is ok, probably is also next substitute from AS34-G

All this modification for better stability of 5V STBY power supply.

Repair description: BAD IC204 (AOZXXXX) DC-DC from 5V STBY (A5V) to 1.1V STBY (SB1.1V - VCORE for IC1102) I use external DC-DC adjustable converter - see picture and instead trimer i use parallel resistors connection 3k3,100k,100k (3.1kOhm)
Bad firmware in IC402 I reflash via firmware from Ерлан.
Description content of EEPROM: Before repair TV not stored some settings (eg. set of initial music, power saving (brightness of CCFL)) and other settings. I backup these content and try write of content these eeprom from LE32A656, but content from A656 have a problem with some settings, so rewrite backup. After I enter to service menu (TV off in stby mode - red led light) push in remote key: INFO - MENU - MUTE and POWER ON. I shoot settings and execute menu item "FACTORY RESET" After rest factory, all settings work fine and check values via photos.

PWR supply board BN44-00209A PSFL171501A - problematic stby pwm IC FSDM365R is thermal stut down (bad cooling and small power reserve) after 10 minutes after TV turn on, just bad design, because this stby supply powered after TV turn on also main 5.3V power line.

Firmware I personally downloaded from good functional TV LE32M87BD and I reflash all flashROMs and config EEproms in motherboard to other same TV type. Bad TV before repair has symptoms: - Red LED blinking and not starting backlight and no screen - only restarts repeatedly to infinity (power on, main power supply section turn on, led blinking, main power supply section turn off, restart and still again).
Bad TV has bad caps in power supply board and bad low drop voltage regulator 3.3V in SUB LVDS BOARD TULIP32 BN41-00895B.

Description: Mentioned LCD panel from Orava LT822A is possible use in some Samsung HD ready TVs after mechanical modification of plastic holder of lcd glass, change TCON power from 12V to 5V in Samsung motherboard and change input of LVDS format (JEIDA versus NORMAL). Also LCD Panel Samsung LTA320AA05 from Orava 32" HD ready model: LT821D (chassis Vestel 17MB12-3) it is possible use for some Samsung HD ready TVs without any mechanical modifications - only change LVDS Option input (JEIDA versus NORMAL) or Motherboard firmware and config EEPROM. I succesfully use these panels in Samsung TVs LE32A330...
Firmware from these TV is suitable use for all TVs with chassis PD92A eg. 50PQ3000, 42PQ3000, 50PQ6000, 42PQ6000, 50PS3000, 50PS6000. - IC110 ATMLH 2FB2 (AT24C512B) SO-8 config eeprom - IC103 MX25L12805DMI-20G SOP16 firmware flashrom
