hello John,

I don't see any chance for repair at home (without equipment and knowledge). The iPad is the one that crashes the most when handled inappropriately. You'll have to remove the screen, it's simple, though repair shops often charge $ 75 extra for fault coverage. You'll have to remove the motherboard - that's where the most problems are. Many technicians have failed at this stage. No experience, rush ... after all, no elementary knowledge of microelectronics. Most rely on YouTube - that's wrong. The lack of schematics makes it difficult, so only experienced electronics can manage somehow. Don't do it at home, it is beyond your technical capabilities and (I guess) knowledge. It is no longer a screen replacement, but an intervention in the electronics of the device, with all the consequences. My advice, find a good repair shop or user who has been through a similar problem in your area (I will try to get you in touch with someone I know who had a similar problem - west AU if I remember correctly). Maybe something will brighten :-)

=== But remember, never ever take your tablet to an unproven repair shop if you want to see it working again. This is a really difficult device to diagnose and repair, I won't mention the manual skills required. ===

And finally, answering your question: ``<br><li>``

* it's definitely not a battery
* charging port, it depends on how it has behaved in the last few weeks. It is possible.  Bay the way, you’ll break it when removing the motherboard, so it's worth having a backup ;-)
* short circuit in electronics or broken connection, motherboard imaging required. This is most likely in my experience. It seems to me that it will be quite cheap to visualize it: buy yourself a USB A(amper) meter from $ 4-5 (it will be useful in the future), make a measurement of the attempt to run through the lighting cable. You can learn many things this way.
## the indication 0.000 is rather a problem with the usb, cable and maybe the charging tape,
## up to 0.250 usb resource management or PMU problem (Power Manager Unit),
## 0.350 - DFU mode,
## more up to 0.750 - after trying to start - short circuit in the logical line,
## 0.850-1.120 normal charging of an empty battery,
## 1.200 and more up to 3.000 - short circuit in the main power bus (with such a current no kidding, turn off and find a workshop)
