broken connector, fixed but not battery charging

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)

self repair universal

Hi, I broke my universal last night :.(
I was using a charger that came with my gps, and it fell 30cm off the bed table and hit the floor, striking the charger cable. The gps charger is longer, so without the rubber collar to absorb the shock, the usb plug twisted inside, and broke the usb connector off the motherboard.

I use my universal very heavily, so I want to get it fixed as soon as possible. I've done simple repairs on laptops and phones before, including soldering on a power connector in a dropped vaio. How would people rate the difficulty of this one?
The first issue will be to get hold of a suitable screwdriver, but I'll also have to source a new usb connector.
Has anyone got any experience or tips they could share?
Thanks!

Hi first of all, based on my experience with opening universal - when you start opening PLEASE READ OPENING INSTRUCTIONS on FTP - there is PDF file for this. And second one - try ty find a cheam MP3 player with same USB connector - you will never belive what is inside of those tousands MP3 players - I even find inside one a DiskOnChip for universal

Thanks, they look like two very good tips! I was actually going to check out the second hand shop for old cameras with mini-usb connectors, but mp3 players sound like a good idea too.

I had the same problem. I fixed it myself too. I just used the USB connector that was broken off and soldered it back.
I don't think a new connector is going to be needed. More likely your biggest problem will be broken off tracks on the motherboard.

Thanks Patrick, I love the net! I've never personally met anyone with the same device, but now here I am talking to someone who's actually had exactly the same problem!
I've now opened the case up (after downloading the beautiful maintenance manual), and it looks like there are indeed a couple of bits of the mobo broken off and stuck to the connector.
I've had a look with a magnifying glass, and it looks like the 4th connector in particular is going to be difficult to match up. I've been checking out the USB spec, and, if I'm reading it right, this connector is only used for a usb hub. I think on the universal it's not actually connected to anything. Really, I'll just be pretty happy if I can just get connectors 1 & 5 joined up again, so I can recharge!
The other thing I'm worrying about is how I can firmly attach the connector back onto the board so that it doesn't easily break off again. I'm considering a drop of superglue to fix the usb connector onto the mobo before starting the soldering. How did you solve this problem? Are you relying entirely on solder to take the load?

Don't even think about it !!! If you put some glue there you can say goodbye to your device if it brokes again you cannot protect device from this - is more cheap to repair him again

You should put this warning up:
Warning, HORROR pictures ...
must be over 21 to watch ...

If you search the forum here you will notice there are hordes of people with the same problem. It's safe to say this is a design flaw of the Universal.

Same here. I stopped messing with it when it started charging again. It doesn't connect through USB anymore, but I can do that via bluetooth as well.

I put some extra solder on the large pads on the side. I have a feeling that that helped put it on the board more sturdy. I also changed the way I use the Universal. Before I would use it with the charge cable atached so the battery would stay full. Now I never move it around when the cable is attached. So now when the Universal is charging, the first thing I do is take the charge cable out and then open the unit and switch it on.

superglue will not work. you must solder it back on.
from those pics it's impossible to estimate the damage.
open it up and take some new pics.

wizzard wont sync

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.
This thread http://forum.xda-developers.com/showthread.php?t=300240 has some suggestions on where to get replacement connectors.

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.

help pls, phone not charging ( not battery point)do i take phone apart?

need help please people.
my phone hasnt been charging properly for a few days now, to get it charging now i have to get one of my missis hair bands and wrap it round my phone and then round the usb cable so it stays in , although today it doesnt want to charge at all now .
ive noticed that the connection in the phone is loose and you can move it round a litle bit,
now the bit i need help with , is do i take the phone apart and try to fix it.?. im thinking of doing this but unsure about taking phone apart ( dont think my phone is under warrenty anymore,) and im guessing the usb connection on the phone is fixed onto a board.
is it worth me trying that or should i just take it to a repair shop ?

take a dry toothbrush, give the usb port a good scrub. dirt often builds up in the bottom of the port and stops the usb plug pushing deep enough to get a good contact.
Have a good inspect of the usb port, bright light and magnifier is good, see if you can see buildup, or a bent connector, or somesuch.
Also look at the usb plug on the cable, its uncommon but not unknown for the metal outer enclosure to open slightly, and make for a weak contact.
Sometimes a cable simply doesn't fit well for no obvious reason, , i have a generic cheap ebay cable that will only work when angled up or down, like yours, but looks perfectly fine, and feels to fit the socket, while the HTC cable works perfectly, so i know its not the port.
If it all looks good, then chances are you have a dodgy connection from the usb port to the mainboard, which will get worse every time you wiggle and bend the cable to get it to work. In this case, you COULD try a repair, but there have been reports on here of some repair shops pronouncing it too fiddly to replace teh usb port, and a new mainboard would be the only other option.
edit - just reread your post and seen that you can wiggle the port. Broken solder, gotta be. Its not an easy solder, so if your a dab hand, then go for it, if not, see above.

Hi iainbp, heresandyboy had this same trouble in http://forum.xda-developers.com/showthread.php?t=903977 from post 16.
It looks tricky!
Just a thought though, I recently bought a cheap phone charger with multiple interchangeable heads for different phones. The microUSB one became difficult to charge with and it took me a while to realise that the metal bit at the end had detached from its plastic casing, and when I plugged it into the phone it just got pushed back into the casing. (got my money back)
Possible with yours?

Might be hardware. The USB board is not soldered but connected to the manboard. Open the case and fixate. HTH

does the dashcharge take some wiggling to activate? @hamzah93 @KaszasM it basically means there is lots of lint in the USB-C port. USB C is known for that. Use toothpick with the sharp edge to rub inside the USB-C port to remove the lint. keep going at it for sometime as the lint is really stubborn. i had to use a safety pin and rub constantly for 2-3 minutes to get the lint out. however using metal is not suggested until you know what you're doing.
Cheers

most of the times its just the connector , i changed a few already ,
maybe he didn't placed well by the change or it's already **** product.
you must push all the way down once i even needed to polish the edge of the usb too, that it matches into the backcover.
in my case as i made from my phone in a hot moment a 1 + "fold" a needed to change beside the battery display backcover, even the smd connector on the board .
but all if them is still fine even the last wich i mentioned in the first post above , now with the new smd ?
take your phone to pieces and free the usb port and try your charger / even better any usb otg.
if it works the trouble is 100% that u must push "down" in the backcover let the red isolation ring dissaper in the cover , if not worked with "free" usbport order 1 more

I changed the connector many times
I ordered one more flex cable and dashboard
I will chang it will replay
Thank u

i had the same issue. i just cleaned the charging port with some water ( i took the risk as it is splash proof) and a cloth and its even dash charging now. But do it at your own risk. i do this often when the problem occurs again.
