USB Problem: Windows can't recognize it

Postby HASJ » Sat Oct 10, 2009 5:20 pm

About a week now, the mp4 can't connect to the pc nor anything. I've tried 360, PS3, PS2, TV, DVD and none of these worked. But, I can charge it. Aside from not connecting, it's working properly.
But yesterday I tried messing with it, and I've discovered the problem.
There're 5 connectors connecting to the mainboard, and these are damaged. I tried (I don't know the term in english) giving it a shock, I tried about 30 times in different occassions, the Windows recognized it, but after a second or so, it disconnected (due to me not being able to keep the position).
On the rage, I've done the most stupid thing ever, I soldered the 5 pins together. Now, if I don't turn off with the ON/OFF switch, it keep on a screen, like it's connected "USB 2.0" and I'm not sure if it's charging.

My questions are: Is there a way to remove solder? And what each of those pins do? Or if anyone had the same problem, how'd you fixed it?

Thanks in advance!

The chip is: AK1022 /7B029AA /02R
The memory is: SAMSUNG 813 /K9LAG08U0M /PCB0 /CSLH81PBC

Here, it is a EletroVision EV-105

Its not so hard to fix it but you need some skill in soldering.

If you dont have an unsolder, take it to any electronic fixing store and they will be able to fix it.

I wanted to fix it myself... But I guess I'll have to do it then, thanks!
