Serious problem turning on the iPad after wi-fi fix.

After fixing the wi-fi controller heating it up a bit, I accidentally disconnected the audio socket ( http://g01.a.alicdn.com/kf/HTB12VebIpXXX... ) from the motherboard, but the wi-fi was working fine, therefore the device had no sound. After some soldering to reconnect the 4 pins to the motherboard the iPad wouldn't turn on again, the processor is not even heating up so I don't know if I damaged some other component or something like that.

The lcd works just fine;

The home button socket has some dust in it so it's not connecting properly too.

Any suggestions would be great.

Thanks
