Hi,
I have a iPhone XR with a non workingn front camera. Messure diode values on J4200.
Pin 1,2,3,19,20,23 are all different diode value then bitmap.
Anyone have a idea how i can proceed?
Is this a good question?

Three circuits to be faulty is highly unlikely. How are you measuring these?
· Red probe on ground?
· Have you compared the readings to a known good board?
· Are you measuring the pins or pads?
Your next step would be to confirm you have PP2V85 this can be tricky as you need the connector to be connected and the camera app open.

@refectio maybe? (a)

when you say different, how much different as readings are never the same as the schematic / boardview. also have you tried a different camera to eliminate a faulty camera

@tech_ni now I don’t have the readings right now, but it was huge difference, 0.6 was close to 0.1.
Ofc tried with a new camera. No luck. And since the readings are only on the fcam pins it’s obviously something on the main board.
