Mac Book Pro 1278 no lcd bluetooth wifi webcam

[Stangl]

Hi everyone, I have a problem with a Mac Book Pro 1278, an 820-2530A motherboard, it turns on "dong", connected with an external monitor it can be seen and it works, but bluetooth, wifi, webcam don't work. Has anyone had the same problem? Where could the problem be? Thank you

Everything is inside the display assembly.

Everything is inside the display assembly.

Oh yes, the problem I tried with another complete group (cover, display and all the other components), even with new cables, nothing, it doesn't work. It seems that there is no power to those components.

Is there a component that manages the Lcd - webcam - wifi - bluetooth power supply? I would like to understand what pattern this diet follows.
