Hardware issue.

[Simon Strauss]

Hi everyone,

I bought a Note 3 with a charging issue. The ex owner says it didn't power one morning and refused to charge.

I search on the web and found lots of fixes to this issue. From the toothbrush to forced charge using a old usb cable or 9v battery. It's pretty obvious that if I'm here they were not enough. What put me onto the right track was a youtube video of a dude who had a usb connector problem and striped the usb wired, not to connect straight on the battery but on the wireless charger pins as they are connected to the battery as well.

I tough it could come from the pin connector, and grabbed my multimeter to check for a continuity from the pin connector to the wireless pins.
here is what I found out:

Red is open circuit Black is closed (being french it was first posted on a french website)



Investigating further this is what I see:



Up to now it could have been a dead pin connector or soldering of the positive lead. But here we go, it would have been too simple! :-D
The positive is still connected to somewhere apparently:



Anyone have a idea of the actual problem?
Any help will be more than welcome!

Hello!
I received new batteries that tested out to be good but still the phone doesn't turn on.
Anyone having a Note 3 could at least test on their unit to tell me if what I've shown in my previous post is the actual problem?
Is there a way to fix the motherboard or do we have to change the whole thing?
Thanks!

It may be a motherboard problem. I am not sure if boards can be repaired, so be prepared to replace it.

Thanks this is what I tough but I'm a cheap *** and I'd prefer to solder back only the broken pieces... Motherboard are expensive!
It's too bad the motherboard isn't segmented.
Like the charging port is separated from the motherboard, if all main parts were separated it would be great. Sad to change cpu/gpu/memory and such if it only minor ic damaged.
