Top row of keys backlight don't light up (every other key).
Hello everyone! I have a 2014 MacBook Pro Retina that I'm trying to repair. The computer was water damaged and everything worked fine except for the top row of keys on the keyboard, what I mean by that is the backlight was the problem. Starting with the esc, F2, F4, F6, F8, F10 and F12 keys, the backlight is not on at all. So I figured the keyboard was the problem (since it was water damaged.) I bought a new top case and installed it, everything works fine but again the same keys don't light up. What can be the problem? I checked for corrosion on the backlight connector on the logic board but nothing is there, I cleaned it out with Isopropyl alcohol as well. Thank you for your help!
Is this a good question?
