820-00165 camera light flashing/not working.

[iClub]

Good morning, I am trying to repair this mac, I have already replaced the u3900 and u1900, but no solution so far. Do you have any idea what it could be ?

Any history available?
Did you try known good screen assembly first?

Yes, I tested more than one display that works the camera.
There was oxidation on the L4007,L4009.

Replace L4007/09/10 with tiny wires.
