I have here an rw6815 the usb connector is completly off.
But the Rest is complete intact.
So i repair it as i can.
I solder the connector by the 4 sideholders again.
And i fix the Power connectors.
mean USB5Volt and Ground.
The only thing that i now need to fix are the USB Signals Data+ and Data-.
Someone an idea to find the signals in the near of the connector ?
I dont can test becouse there is no rest of the line.
And HP makes good work in the circuit board i don´t can follow the lines by holding a lamp so it shines through
And heres no XRaytub laying around but i think si sold wish me one by Santa at next Christmas

Hi,
I currently repair XDA Exec's for a client of mine who use them for their delivery drivers. They are constantly breaking the screens which are easy to fix, but more often than not they smash off the usb connector and leave it rattling around inside. This is not usually a big problem to fix unless the pads that the 5 pins are soldered to have been ripped off the board. I have found that even if I successfully replace the connector with a new one and solder the two outside pins (which are the gnd and 5v pins) the battery will not charge. The puzzling thing is, if I remove the battery, the red led comes on, presumably indicating power to the device. As soon as I connect the battery the led goes out and the unit boots up only to reveal that it is not charging. So I'm presuming two things:
1. There is some other electronic component damage in the unit caused when the connector broke (due to it being on the end of the charger cable at the time, if this is the case I will scrap the unit)
2. There is some feedback from the battery that the charger needs to continue with it's output and because I didn't reconnect the data pins it won't charge.
Does anyone know how the charging circuit works and what pin / connections are required for charging. I guess the same principle will apply to many PDA's & mobile phones.
Thanks
Rick

Hi,
Thanks for your reply, call me a lemon but what utility do I need to unpack a .lemon file ?

Forget that last post ok...
I'm starting to have real problems with my USB plug. At first it would drop charger plugs when it was on the wall, so I put it upside down. But now I can't connect to the PC all the time either. I have to jiggle the plug a bit or even breathe down in it (the moist makes the connection better). Has anybody else had that problem and fixed it in any way? I suppose the plug is soldered on in such a way that it has to go to a workshop, right?
i strongly suggest you to send it for repair or resolder the base of the connection(this is user servicable provided you have some soldering skills) so it doesnt wiggle. i'd probly even suggest to hotglue the plug but before you do so make sure the plug is sitted properly and it does sync
the same thing happened to me and with a bit of jiggle the plug broke off and now its permenently damaged(ie it will never sync via USB again) so far with self repair i only manage to make it charge
i got no idea how to reattach a 10pin mini USB plug to my board and some of the copper tracks looks damaged which means if i send it to the shops, its a $500 repair and a board swap
I have a problem with charging and i guess also USB connection.
When i plug in a usb cord to the phone i have to hold the cord upwards for the phone to recognize its there and start charging.
I guess the connector on the phone is somehow damaged but i cant see any damage to it.
Is there a quick solution for this or can I replace the connector?
Maybe you have torn off your mikrousb connector from the board. If you have good soldering skills, then you could try to disassemble the phone, and re-solder the connectors contacts. If you have no such skills, then better take it to a repair center to do it for you. I suggest not to charge your phone before you repair it, because you can damage the charging circiut, or force the charging socket to come loose, and damage the circuit board.

Thanks mate, I've got a good friend which is very skilled in soldering, i'll try to dissamble the phone and take it to him.
Is there any good dissamble guides for the HD2?

Thanks again thats perfect..
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?
Friends the socket was removed and points also ... now the service is bad , i try to solder it but the hole small socket get broken and also the some points get removed , i try to put small metal inside big connector and connect the flex cable to that one and i solder cable from side the connector to the out side of flex cable but the signal is very bad any why to fix it without plug and flex cable as they get damaged ??? like soldering wires between area's ???
So either the motherboard or the USB board lost the antenna connector. Hopefully it's the USB board as you're going to have to replace the board based upon your description.
