I have 820-3330-b 17 inch MacBook woth no water damage but physical damage i hear the chime and i light up the apple on the back with flash light to make sure is backlight issue and the computer is booting in OS. I check the F9700 was blown i replace it and after that Q9706 got burned smoke came out. So i remove F9700 and started measuring i've noticed that LCD_BKLT_EN is missing and when i follow that line takes me to U9600 GMUX and i dont even know how this thing work. Any Ideas ???
