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
