820-3332 No backlight after liquid spill

Hi, I have a macbook pro A1398 with a 820-3332-A logic board. The keyboard and screen backlights are both dead after liquid spill. I cleaned up the board. I checked the fuse F9700 and shows continuity. I found some answers suggesting replacing the wled driver with an lp8545sqx but my board has a national semiconductor VM22AC 45-EXTJ at U9701.

What should I do next?
