Depends whats wrong with it. If connection is dislodged a fix might be possible. Otherwise you can replace the speaker.

You're the third person to do this on this Forum. Problem is finding the parts. I think one thread suggested someone on e-bay had some but I could be wrong.
Cheers

Hello all...
I just stumbled upon this in another forum...
Don't know if it could help anyone with bricks??

This phone use an msm7230 cpu and the voltage used by it I guess that is 2,6Vcc. You can search it by probe function in riffbox or by multimetter in comparation with another known jtag like is for example wildfire,desire and for other that use logical i/o 2,6Vcc. In many phones that I found the jtag pins without desolder the cpu this was the nearly value that was the same at all:
trst-0
tdi-2,6
tms-2,6
tck-2,6
rtck-0,04
tdo-0.04

Hi I have a problem with my htc hd2 leo
by a short circuit and I did not recognize the pc or charge the battery with the charger, take it apart and found a resistor (not sure if that) burned this entry serca usb up a few that are vertically this I say this is the only horizontal that way.
anyone have any idea how to fix it or is it burning?
if anyone can help me because I live in a capacity that no one notices this type of cell.
The rest of the cell all goes well

Well, when it is burned like you said, then it will by very hard to get a new transistor for it. So maybe you could search on the second hand market for a HTC HD2 with a broken screen and change that part on the photo.

I know it says it's for xperia play, or something, but the guy said in his thread that it should work for all OTG devices.
I however don't have a usb hub right now, so if anyone with soldering skills wants to try this, let me know if it works.

The potential to brick your device by shorting it out is high with this, someone with balls of steel would need to test it.
basic circuitry looks okay but I don't know if the sony devices do anything funny to allow for this on their official dock, you also may have to experement with different ohm resistors to find the sweet spot for our device.
