Hi Everyone I’ve got an iPad 4 sitting here which i’d like to try and get working again. It was brought to me and simply wouldn’t turn on. No drops or liquid damage , never been opened. I’ve cracked it open and replaced the charging port. Still no good! I’ve also got a spare iPad 3/4 battery (which I believe is compatible? However despite this battery being charged , I still couldn’t get any signs of life out of the iPad. Is the logic board totally dead? Would appreciate some suggestions on this one! PS: I also have an iPad Air with exactly the same issue but I think that needs a new charging port and i’m not very good with a soldering iron :P Thanks!
iPad Air charger port uses a charging port flex assembly that is basically a daughterboard that plugs to the logic board. So you will not need to do any soldering for that one. Now for the iPad 4, this is almost certainly a component IC that has shorted / gone bad. Power Management IC is most likely at fault.
