Chosen Solution

iPad Air 2 wont turn on or charge, there is absolutely no signs of life. i measured it via lightning caple to input voltage about 5.20 volts but not any current, it says 0.00amps even after charging overnight. Tried hard resetting multible times, no luck. iTunes doesn’t recognize it at all. I really want to see if i can fix the problem without taking it apart, since i dont want to risk cracking the expensive display/digitizer combo.

Maybe you have a bad dock charging connector?? Is the charging cable loose when it is inserted in to the dock Has you do not want take apart the iPad ?/ bu what you are saying you will have to The Thristar tester would give you a good idea what is faulty but not 100% full proof Link https://www.repairsuniverse.com/products
