      I found a broken pin in track pad connector on the board, I repaired it.
      but the same problem, I replaced also the track pad and the flex.
      I will upload a picture for the sensor issue

        The first suspects there are trackpad and ALS.
        I still suspect trackpad connection in your case.
        But try disconnecting camera cable.

        Just in case, post diode mode to ground and voltage for R5222/23.
