A2337 - Camara doesn't work

[soeren]

I have replaced the display on my A2337 and I believe that during the change the battery connector was re-connected to the logic board and therefore I now have a non-working camera in my A2337 laptop.

After the problem occurred, the camera was no longer detected and True Tone didn't work. I replaced the eDP flex cable (display connector) and now the camera is detected and True Tone works again.

The problem is that when I open Facetime, for example, the green camera LED does not light up and the camera image remains black. In the end I get an error message. Does anyone know what is fried on the logic board or where I could start looking?

Thanks.

What do you mean with "Lock" ?

So I assume it is 820-02016 which I don't have the board view or schematic. I had the issue with a 16in a while back after replacing the battery. Took all day to catch the little guy after wondering what is the root cause. Check the pin 29 to 31 on the connector in diode mode.That is the most common problem. If I have the schema, I may be able to look up and point out which one to check.

I had another one with no camera after removing the board and reassembled. The Ferrous inductor for the camera was burnt. There is nothing serious if you look at the circuit for camera. Mostly the inductor just died.
