IPad air A1475 Not charging Hi, I have one iPad air A1475. Everything works fine except charging. There is no water damage. Charging port seems to be fine no sign of damage Pins or water. i tried to re-solder the connections pins but still no luck. Does anyone know what else can be the issue ? Thanks. |
While plugged to charge, test C8145 for 5V and let me know. |
can you send me the location for C8145 ? i will appreciate, thanks. |
http://forum.gsmhosting.com/vbb/f631...-here-2180895/ Download schematics then open iPad Air schematic and search for C8145. Not hard!! Sent from my iPhone using Tapatalk Pro |
Thanks but its asking me the password to open up a PDF file. zarbourne is for extracting the zip file. |
The password for that file is in the filename vietmobile.vn or something like that Sent from my iPhone using Tapatalk Pro |
hey zarbourne, this is what i did, i changed the charging port and now i am getting power when the ipad is off but when it comes on it doesn't charge. i have also attached an image of my ipad air with voltages. |
i have the same problem. I have the 5V in C8145?which is next? |
I still haven't found a solution. How about you ? |
Same problem i received iPad Air A1474 when off show charging ok when power on no charging at all. i change charge flex cable and U6000 ( 1610A1/1610A2 ) both not work. any idea? |
Same issue with 2 ipad minis (2nd & 3rd gen). Replaced u1300 w/ no change, then replaced q8104 w/ no change. Saw this thread. Check volt on c8145 and it shows ~4v. just replaced the q8123 w/ no change. ipads are not drawing power. Any ideas? |

I assume you changed the diodes as well? although D8100 would probably give HDFU so easy to spot. Now I realise this is gonna sound stupid but you did try a different battery at the start .... mostly I have noticed case cracking at 20x mag on failed tristar chips. I have lots of weird battery issues, 2 only fired up when heated else device not charging at all and device showing dead battery icon! lots that refuse to charge from logic board and suck the life out of my psu. I always use a known good battery now before i get the soldering iron turned on lol:) |
Have to give up on the 2 minis. Now have Air 1 with same issue. Verified C8145 has 5 volts. This runs into Q8123 (usb charging ic) which is receiving 5 volts but going out to DZ8120 is 0 volts. My guess it's either Q8123 or U8100 that is bad. Planning to replace u8123 and see what happens. |
on ipad devices or charging flex or u2 chip i dont know but ipad air1 few of them with u2 problems br zoran |
did anyone get a resolve on this issue |
