Samsung E720 went for a little DIVE.

[eskerra]

Ok, I have a Samsung E720, that went into a pool for a while.
The client says just for 10 seconds, (enough I think, jeje), he took it out, put batery apart, and he dismantle the whole area where the main board is, and the keypad. he dried everything with a hairdresser.
Now the phone DOES power up, screen is perfect, image as well, sounds good, the tipical samsung melody.
The problem is that only the keypad DOES NOT WORK AT ALL.

I have cleaned up the mainboard, with a little brush, alcohol, and destiled water, i have brushed very carefully the flex conector.
But still same trouble, NO KEY PAD AT ALL.

Would it be necesary to dismantle the upper part of the phone????
Where the screen is, or its just a problem of the keypad, flex, mainboard?????


Thank you for your help.
Kind regards.
