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
CPU: U1 AUO-016K1 smd 208 pins multi DC-DC converter: U2 BD8166EFV U401: Latice LC406-10I programable logic array U11: I2C BUS EEPROM Atmel AT24C32AN SO8.

All this modification for better stability of 5V STBY power supply.
Не исправность не стартовал только дежурка,на пульт и на клаву не реагировал. U6 выход 0.4 вольта должно 1.8 вольта. Заменил и все заработало выход 1.8 вольта.
