Re: Sony xbr65x900c sound yes, no backlight or image.
if you by mistake touched next pin to 18... then need to do this
pin 17 = PANEL_PWER_ON it should read >3.0V okay.. if no change IC
pin 19 = power on >3.0V okay
then while the tv out from wall check pin 18 of this IC if it read short with chassis... if yes then need to replace the IC
If BL_MUTE (R9174) is 0V and pin 18 read >3.0V and its not shorted with chassis... need to replace IC91017
