iPhone 6S Plus Main Camera, 3D touch and flash light Not working
I have an iPhone 6S Plus with some issues. Main Camera and 3D touch Not working at all, flash light Not Working too. I checked the motherboard and I see sigh of water damage but everything else works fine. Do I need to replace any IC to solve this issue? What parts do I need to inspect with the microscope and test? Maybe some parts (like Resistors, Capacitors or IC) burned. I would appreciate your help. Thank you!!!
