[Photo] Changing button break a component for chip :S

Hello!

I dismantled the phone to change the power button and when I turned up no signal. Constantly stay in "searching". I've been reading quite possible solutions, but then to try them all, I decided to check the motherboard and I found this. Is there any solution? : (The phone does not recognize if I remove the chip, and "modem firmware" is blank.

Any suggestions?

Thanks in advice. Sorry for my bad english, i'm from Argentina.
