hi i have this macbook that the customer says he spilled water on the keyboard. I disassembled the board which is clean and the mac emits the charging sounds but I can't see anything both on the lcd and external

Inspect J8500 for corrosion...

I cleaned even though it was already clean but nothing

Check diode mode to ground at pins 1 & 3 of J8500.

pin 1 short
pin 3 ok

Then CPU eDP out is fried.
Test if you can get external video, with J8500 disconnected.
