Nokia 6230 water damaged No Reception after ultrasonic cleaner
 

I dropped my phone in the kerb were there was a massive puddle and leaves and it stayed there overnight.
I found it today and it wouldnt switch on nor charge.
Now i have:
fluxed and cleaned the PCB in the ultrasonic cleaner,
changed the keypad
changed the body
changed the LCD.

Phone now powers on and charges and connects to PC.
The only issue is that there is no reception and the keypad lights stays on.
What is the next step?

Mate it sonds as though it hasn't been cleaned properlystill , or is still wet under the I.C's.When you say you fluxed and ultrasoniced, what did you actually do? Did you ultra , then flowed , or what??
