How to change the mic?

Hi,

I have a Microsoft Lumia 950 Dual Sim, call mic(s) are dead. Can't use phone for calle to other people (using the headset is good workaround), and can't record voice, recorded videos have mono sound, on skype video calls people can't hear me (speakerphone is working). They were working fine when I bought it. One day they just stopped working after accident with water. It does not have warranty, though, but will try to contact Nokia Care if they still exists. Can you help me to replace it myself?

If it would help, I can provide you photos of motherboard to identify chips.

Other side I will send later today.

I wonder where could buy such parts.

Thank you.
