If keypad not working after water damage - change microphone. It's wery strange, also remove it - and will be OK!

I manage to repair E700! :D
I used teethbrush and alcohol to clean the PCB, and after that I puted the PCB into the Infrared owen, temperature 120°C, time 90 seconds, to dry it!
And after that keypad is working again!!!
PS. My phone was able to switch on and off, but all other keys wasn't working!!
hehe my toothbrush make a wizzard all day long, as yours i see. :)

Your problem is in this area,and you need to resold it but not with hot air!
Hi!
Had the same problem (nothing except the ON/OFF button worked).
Tried microphone - unsuccessful.
Tried resoldering the described area - unsuccessful.
What worked for me:
Got a toothbrush (essential for a service point :P) and some isopropyle alcohol.
And brushed bare PCB (peel off the clickpad!) thoroughly..
Good luck!
