Hi guys, I need an advice from an iPad repair tech. Got a Air 2 that doesn’t power up, no sign of activity. When I connect the charger I get 4.5v and 2.5amps on the usb tester. There probably a short somewhere. The iPad is not open yet, I checked the charging port under microscope and it seem perfect. So where could be the short inside ? Thanks, any help is appreciate :-)

hello lemerise,
You probably have micro cracks in the dock tape connection. 4.5V is not a native value via usb (it should be 5V) and the 2.5A draw suggests a charging problem in tristar's lines. You have to open device. Ipad air2 is enought mapped, you'll not have got a problems.

OK thanks, I'd like to have a tristar tester but I'll order this chip and replace it.
no, do not replace without checking (after all, it may turn out to be just a capacitor in the line). I am not a supporter of replacing elements with no 100% certainty. Get the meter and check the lines. You don't need testers, wonders, or sorcerers. Only knowledge and the desire to solve the problem.

If there was a short on power rails I don’t think you would get a draw of 2.5a through the charging port it would usually be 0a. Have you tried connecting to a pc with iTunes to see if it’s recognised.

Yes, still no activity connected to a Mac and nothing on iTunes. Could it be a short in the lightning port ? Thanks Daniel
