This is certainly typical of a Tristar failure. The iPad Air 2 does not have a Tigris IC, all of those functions are handled by the PMIC. So regardless of wether you or a shop attempts the repair, Tristar will have to be the first option and hope that it is not PMIC related. While you have the iPad opened up, I would check the condition of the charge port by looking for cracks right near where the metal part of the port is soldered onto the flex. If you can see cracks on the flex, then change the port as it will fail much sooner than later. A good clue as to the flex cracking is if the retaining screws are loose.
