Hello, after oxydation of the trackpad and the keyboard control board, we replaced these two parts.
Everything works except that the F1/F2/F3 keys, etc., don't correspond to the actions offered (volume control, brightness, etc.).
We replaced the keyboard, the same thing, and did a DFU restore.
We replaced the keyboard, even the entire keyboard part, with a used one, and the same problem.
So, I think it's coming from the motherboard, but where?
thanks

Be aware, KB and TP must match the model.
Weird behavior appears if you mix them.

Actually what action have the special Fx keys?
Also test them holding down Fn key.

Use an online keyboard tester.
