Hi folks. A friend gave me his phone after he dropped it in water, and then tried to fix it himself.
The connector on the motherboard has been pried, so half of its cover is missing and some pins are tangled up inside.
I'm guessing about 4 pins are mucked up; the rest are fine. But the phone will not power on..
I'll try to include some pictures.. Any ideas how to proceed? I thought about soldering tiny connections from the MB to the ribbon connector.
Replacing the connector seems equally difficult due to the number of unsoldering/soldering to do..
Any ideas what to do?
PS: Forum attachment limit is silly; I'll link to external images on my server instead..
Check the pins of the connector that has an "MB" label on it:

Many thanks for any feedback...

ok, the connector is broken.
I disassembled cover parts,
fixed connector,
I'm sure there is 5V inside (the connector inside I measure by voltagemeter) when I plug-in the external charger. The connector has 3 pins for GND and 3 pins for 5V and I'm sure there is volatage inside.
But the battery is not charging. O/S say the battery status as remained, but do to charge.
how to fix? what next to check?
crying:
You could check to see if the protection fuse has blown, if so you can bridge the circuit, if you search for charging or charge on the forum you will find pictures and methods.
the protection fuse just beside the battery? under small piece of white scotch tape?
fixed
thanks for suggestion.
yes, it was broken micro fuse, the one right beside the connector pins on motherboard.
Glad to be of assistance, hope its all ok now. 8)

Hi Jgui, could you tell me how you managed to repair borken connector at th bottom??
I search for a repair shop for my MDAII or th way to do it myself...
thanks a lot for your answer
Hi everyone, very upset about what happened to my universal, the slot used for recharging snapped of the other day from the motherboard. I have taken the case off, and soldered the 4 connecting points of the slot itself, however it does not recharge still.
It has 4 prongs underneath, relaying to 4 metal strips on the mother board, must these be soldered, could I just solder these 4 pins to the motherboard in its entirety together, or must they be individually seperated.
Sorry if you find my english hard to understand, its kinda hard to explain everything
Any help would be gladly appreciated, I dont know what to do if this doesnt work as 02 said I need to replace the whole motherboard for 100 pounds when it just needed soldering
p.s. the connector that is broken is defined as CON715
OK, I'm a ****.
Just came to remove my audio daughter board off my M500 to solder up the dodgy joints on it, and the whole bloody connector came off. I've removed the connector from the daughter board, but when attempting to resolder it, I managed to break the connector
So, I need a source of the little rectangular PCB connector (14 way, DIL) that attaches the ADB to the main board, so I can have another go Anyone know a source in the UK preferably?
Cheers

hey all these days my wizard would sync perfectly but today it jsut charges and doesn't sync i did a hard reset but still don't work .. i tried in a different computer and it doesn't even identify it
anyone have this problem???
had the same problem. all days it worked and then suddenly just charging (no sync, no identification). I also did a hard reset but this changed nothing. then I did not use my wizard quite a while (about 3 months)...tried it again and it worked perfectly fine. i have no idea where the problem was...so mate I have no idea how to solve it but you see...there was a happy end
I just got given a Wizard and it's got this problem too, charging but no sync. Problem with mine looks like a damaged mini USB connector. I can see that the plastic in front of one of the pins on the bottom of the phone is broken.

how easy is to replace this connector.
i have replaced the screen and got all the way down to the MOBO but i didnt see that mini connector.
edit: i meant i did see the connector but its soldered to the MOBO so i was wondering if this can be replaced.
im having the same problem
In the forum link I posted above people have said that you can damage your MOBO easily if the PCB gets too hot when soldering.
I have access to a hot air tool used for SMD components, which lets me heat all the pins on the mini USB connector evenly. Using a soldering iron would be more difficult and increase the chances of damaging the MOBO.
Hi guys,
So the micro-USB port on my Galaxy S3 got spoilt (details here).
I ordered a new port and tools, and I've opened up my phone to get the PCB out with help from disassembly videos on youtube. But I want to get some help (videos or just talk through) for unsoldering the current port and soldering the new one, coz it's tiny. I'm an electrical engineering junior at college, so I have experience soldering pins on breadboard chips, but nothing smaller than that. :/
Looking forward to some help, guys! Thanks
I was waiting for somebody else to jump in, but since they didn't...
You can solder teeny-tiny things with non-optimal tools.
You just have to be careful.
I'd suggest that you get some old junk circuit board and try removing parts first.
You don't want to apply so much heat and pull so much that it pulls the copper off the board.
Solder wick or solder suckers can be helpful for removing excess solder.
For a connector, I add solder to make a bridge over the contacts, quickly dance the solder tip over all the contacts and lightly pry the connector with a small screwdriver.
Clean up the board removing excess solder.
Clean the board with a Q-tip and some rubbing alcohol.
Tin the new part with solder, then "smack" it to get rid of the excess.
By now there should almost be enough solder on both the connector and the board.
Position the connector and dance the soldering iron over the contacts.
Inspect with a good magnifier (if you have one).
I just did a 10 pin 1mm pitch ribbon connector this way.
Now I have a kernel console on my Nook.
Good luck.
Edit: Oh, I didn't see the other post where your problem was just a dirty connector.
Thanks!
Thank you for the reply. I still haven't fully resolved the problem. Cleaning the port out has returned charging abilitiy, but I can't connect the phone to a PC as a USB device still. So I might indeed need to use your guidelines above eventually. Thank you for them, and congrats on that Nook kernel console!
