Satellite phone left out in rain. it was face down and now won’t work. The Rain must have went in the speaker holes on back and now it doesn’t work. I checked the Battery and it is good. How do I fix it?

The first thing to do with water damage is to disassemble the device and clean the corrosion or water off the components with isiprople alcohol. After this inspect the board for damaged components which would be blackened or deformed. If everything looks good reassemble it and try to turn it on. If there are damaged components replace them. Ifixit did a great series on water damage here http://m.youtube.com/watch?v=DsDpALKQjUQ. Hope this helps.
