MBP a1425 no backlight & already replaced fuse. Next step?

Hi there! As you can tell from the title, I have a a1425 MBP that encountered minimal water damage. A few drops went into my keyboard and then a few seconds later, my LCD screen went out. I still have video on the LCD and it works perfectly if I use the HDMI to my TV. I have already replaced the P fuse on the logic board and I am looking for the next troubleshooting step. Any help would be greatly appreciated!!

Also, i’m comfortable with micro-soldering! :)

TeddyV you are changing a lot of parts based on some "interesting" suggestions. Have you yet measured to see what and if you even have power to the circuit? Have you checked your display cable connector on the board? What have you checked? What 820-xxxx numbers are on your logicboard?

Did you look at Louis Rossmann's YouTube vids? A1425 Retina turns on black screen

I did. He did a lot of work on that logic board!! I ordered a U9701 backlight chip per your suggestion from the video. Thanks for your help, Dan. I will update my status once I receive and replace the driver.

So i replaced the blacklight driver but that did not fix it. Could it be a keyboard issue? The backlight buttons do not show the "backlight overlay" on the screen?
