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.
TV Model: 32PFL3605/12 chassis TPM4.1E LA Assembled in Poland Motherboard: 715G3786-M1A-000-004X (WK:952) Power supply and inverter: 715G3816-P01-H20-002U CPU U4201 MT8228TMMU Firmware flash: U4104 SPI BUS Winbond 25Q32BV SOP8 in file Config EEPROM: U4103 I2C BUS ST M24C32WP SO8 in file TCON EEPROM: U7202 I2C BUS ST M24C32WP SO8 in file Repair descriprion: BAD IC901 TNY277 in power supply, so 5V STBY power supply have maximum current 300mA (internal resistor in IC from source of mosfet to (-) 380VDC) I use slighty veaker type TNY276 and use bigger capacity of C912 100uF/50V 8x11 (original 47uF/50V Capxon GF), replace C933 1200uF/10V 10x12.5 polymer X-CON ULR with max. ripple current 6000mA at 100kHz (original 2200uF/16V Capxon GF 12.5x20) and replace C934 470uF/16V 10x12.5 Nichicon PW (original 47uF/50V Capxon GF). All this modification for better stability of 5V STBY power supply.
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
