Ipad Air 1 not turning on, and charger is reading 0>200>400 mA
I'm trying to fix an ipad air 1 that is not charging and no image on the display. Since it was not responding i tore it down up until i can access the battery in an attempt to restart the system by plugging and unplugging the battery.
After that the problem persist, no image on display , and no indication that is charging. I have a cheap USB current tester and it would seem that the charging current is jumping from 0 mA to around 200mA to around 400mA then go back to 0mA again (over and over),
Anyone can help me diagnose the problem?
Its now charging i think but very slowly, meter is reading 5v at 500mA. I know that this brick and cable can do 5v 2A on my iphone. Also the red battery image now shows up on the display, disconnecting the cable shows the lightning image at bottom also. Will let it charge for a couple of hours...
