[SOLVED]water damage a1534 with no backlight

[elcapitan]

I got a macbook A1534 2015 that came in with water damage. It turns on completely but the image is very fainted. It looks like there is no backlight. I cant find any schematics for this model. Anyone knows where the backlight circuitry is on this board? or what i should be checking? Thanks!

After troubleshooting the backlight circuit with the schematics. the issue was due to corroded led connector on the screen. i replaced it and now the backlight works properly. You can close this one. thanks!
