XBX/XBS Controller PCB Scans, Traces and Info - 1914

I have changed that component from a donor board and now it works correctly

Same issue with my controller, it does not work when antenna cable is connected
tried to remove all components connected to ground  (close to antenna and usb connector) on bottom board but still it does not work

what did you replaced at the end to make it work again?

Very strange RSY behavior.

When potentiometer soldered I have about 1V at middle pin, but gamepad test shows me min position of RY.

When I move stick and got about 1.7V at middle pin tester show middle position of RY

At max pos of RY I got 1.8V and max position in tester.

Movement in range 1.65-1.8V only. At other range - min position.

13 pin at 1914 SOC BOARD board have the same voltage and resistanse about 0.1Ohm between middle pin of RY.

By sheme this point goes directly to ARM chip.

Is it ARM damaged by this line? Or bad contact and maybe rebolling will help?
