Not booting up - dead logic board?

Текст:

Hello!

I got a broken iPhone from a friend, who dropped it into water. After that backlight wasn't working, so he tried to change a coil as shown

[http://www.youtube.com/watch?v=zHaWA6hGgeM|here]. After fixing up some soldering and cleaning off the flux with acetone, I closed it up and attached it to a charger. The phone showed some life signs (battery charge screen), I left it there a couple of minutes, but now the screen is completely black, and it is not recognized by iTunes.

I have access to a small electronics lab, so measurements are not a problem, the thing is, how can I test if the logic board's alive? Are there any test pins I can check?

Thanks!
