water damage 820-3476-A running super slow

[Modder1]

Hello everyone, I got a Macbook Pro A1502 (820-3476) that was previously water damaged. Its running super slow. There isn't any corrosion on the logic board. After running the ASD I noticed there was a problem with my camera sensor. I troubleshooted this circuit and found a short on cam_sensor_wake. I have tried to remove most of the components in this line but i can't releive the short. Am I looking at the wrong place? I traced this line down to PP1V8_CAM and this line seems to be fine. If anyone can help out ; it will be greatly appreciated. Cheers!

camera disconnected?? corrosion under J4002??

Thanks for your input bro. the camera is disconnected. It needs to be replaced due to the corrosion. I have desolder J4002 to ensure there wasn't any corrosion underneath causing this problem but still the same thing. Duke can you enlighten me?

Cam sensor wake is supposed to be tied to GND, did you bother to look at the schematic and trace out the circuit?

Run ASD to see which sensor is fucked.
