I recently bought a used Sony xperia z3 D6603 on eBay. Everything worked fine expect that I couldn't find any access point on WiFi and any devices on Bluetooth. Finding this fishy I removed the back panel and took a look at the motherboard and found that the WiFi antenna pins above the micro USB port were totally missing and it was replaced by some solder lead. So I googled for the pictures of the motherboard to try and figure out the circuit but it was difficult to understand the circuit on the motherboard. if anyone could send me the circuit diagram or suggest an alternative way to fix it ,it will really help me fix this. Thanks in advance

My Xda/Qtek's charging slot is loose or bent and as such I am now not able to charge it or synchronise at all. Brought to the repair shop and was told that I need to change the whole mother board as the slot is attached
to the board and it is as good as getting another one than to fix it. Seems to me that the 2 pins in the centre or the slot is bent and I cannot get the connection on when I plug the charger in unless I twist the charger to one side I then get the yellow/orange light which indicate charging.
Appreciate if someone could help fix it. Cheers.
The charging socket is part of the mainboard, I have had this in the past with ipaqs, I got a jewellers eyepiece and a very slim pin and managed to get them lined up again, I am sure there was a post today about this very problem.
Thanks for info. I managed to strip apaart the xda and then soldered the
loose charging slot. It works fine now and I save having to pay for the replacement of the main board which is not worth it and also the service
costs.
help for newbie pls?
Hi, I currently have the same problem. I also want to try the solution that cruisin-thu suggested, unfortunately, I'm not much of a techie and I'm afraid that I might damage the mainboard if I don't know which parts to move. Does anyone know of any sites that have a picture of the xda II mainboard? I'd really appreciate the help.
Hi
I have major problem with my tablet and usb socket has been pried from board have taken a quick look at damage and a replacement or solder of new one is out of question and metal contacts on pcb has been damaged also.
I am wondering if anyone knows a way of bypassing so I can still charge.
Can I bypass the small circuit board where USB connector is and hard wire battery connections directly onto USB itself.
This tablet has always served me so well dont want to give up on it just yet as cant afford a new one.
Fairly confident with soldering etc just curious as to whether it will work and best way to wire it up
Hi guys,
i got a problem with a M2 Aqua. Last week my battery was like 5% left and I wanted to charge it. While connected to the charger, the phone hadn't charged at all. Also the red led that indicates charging wasn't showing. As the M2 got to 0% and shutdown itself, I tried everything. To keep this short, this is what I've tried:
Charging for 24h+
Tried entering flashmode
Pushing Vol+ and power button for hard shutdown
Tried SUS, Flashtool, PC Companion and other software
Tried pushing the reset button hidden next to the sd card slot
The phone wasn't recognizing at all. :crying: The led on the top right of the phone hadn't even lighted up once during my tries to recover the phone.
Since the phone wasn't recognizing at all, I think either the battery or the charging / microusb socket is broken. There is also the possibility of a mainboard failure. How can I test the battery for functionality? Is this even possible? Would the phone boot up when connected to the charger even if the battery has a failure?
If the socket is the problem, I'm going to replace the whole PCB at once, because im not very good at soldering.
Maybe some of you can give me some insight.
Thank you.
I dot know about this device but others function without a battery being present. I've opened up a generic tablet before and swapped over a soldered battery, I had it powered up sans battery.
Obviously you've tried different chargers? USB cables or connecting it to a pc and see if it recognises the phone or any messages crop up.
Failing that try taking it to a service centre or repair shop. They might open it up or diagnose a fault for free. I've not looked inside the Sony m2 but some phones have ribbon connectors inside that simply fall out of their sockets, it might not be the end of the world.

i have an unlocked xperia m2 pcb but its not an anqua one just lte m2... just fixed my girlfriends m2 and used full handset i got from e bay guy said was not working as didnt read sim card, turned out the main board was fine just the sim reader was faulty lol
As per the title I am getting a much diminished signal after changing the charging port to a new one.
The worst is when I grip it in my hand which would naturally be at the bottom - where the charging port is.
I only get LTE when I'm outdoors and indoors it's either H+ but usually H, E, or even NO SIGNAL.
I can't figure out what could be the problem. There are 2 antenna inside the unit that connect to the charging port but these are bluetooth and wifi. It doesn't appear to be an antenna for the network signal. Or is the frame part of the network antenna? I see some electronics in the frame when I dismantled and I don't know what that is for or how it connects to the mobo. I'm thinking if the frame works as an antenna maybe it's not connecting to the mobo properly.
Just to clarify I was having no signal problems before I dismantled the unit and in fact it was working exactly the same as my previous phone.
I actually don't know if the charging port part has anything to do with the signal antenna.
Any comments appreciated.
Hello,
I'm experiencing the same problems with my SM-G920F. After replacing the charging port the bottom mic isn't working anymore. I'm forced to call on speakerphone to get the sound to the other end of the line. The repair centre who fixed the phone said it could be because of a little off-point alignment when soldering the usb pin on the pcb. They also said that they experienced the same problems on different repairs for the S6.
Any thoughts?

Please start you own thread on your issue. It has nothing to do with this thread. Mod please remove this post.
I think I know what happened. When I took off the back cover plate it was glued to what looked like a Printed Circuit Board antenna and it was yanked by myself. Anyone know where I can get these type of things to buy and repair ?
I'm disassembling my Xperia XA then i accidentally removed something near the charging port. Is it okay or i should go to technician to resolder it? By the way i lost the removed part and i can't find it.
The removed part has the same appearance beside it.
Help please
