I had this problem and just fixed it. The issue is that one or two small SMD components can get torn off the board if you are not careful when prying off the clamp that holds the screen connector on. They may take the pads with them when they are torn off. When they are restored, the Mic 1 circuit works again. A very helpful chap called Stefan from GadhetUK' Discord identified the conponents. They are both 0201 size. One is a 51 Ohm resistor (missing component above top of blue arrow in pic 2 below) and the other is a 33pf capacitor (missing component just below tip of blue arrow in pic 2). You can see I tore both pads off the resistor but was able to tin and pick up from a tiny area of the pad that was left. The two pads in the middle were joined. Basically, the resistor and capacitor are joined in the middle at the middle pads. The other end of that capacitor is just a ground. You will need a microscope, tweezers, flux, a steady hand, a very fine tip and some very thin leaded solder. I used 0.3mm.I didn't take the board out but got a little solder on the screen connector but mistake. It cleaned up with braid but is very delicate and there is not much room in there so be very careful.
