Another wet but nearly repaired?

Hi,

First thanks for your help.

Wet phone i cleaned the motherboard with destilled water in small ultrasonic cleaner and then cleared with isopropilic, let dry and everytihng went fine. It took a couples of times to put on and take of the battery but it worked. Turned on. Everything fine but central button wasnt working properly to go to the sides. It did fine up and down and press function.

I re-opened and paid more atention on cleaning this central button conector and area with isopropilic and brush.

I re-assambly it and it does turn on anymore. Batery shows to have 3.17v.

I have tried with a new button and nothing.

Should i have 0 resistance on those same pins in the board to check is fine?

I havent cleaned the back part, but it worked like it is before....ill try that.

Any idea? How can i discharge before rework as its printed on the motherboard? I do pressing on/off button without batery, ....could it be because of that? Estatic energy? Im getting crazy with this....cant understand...

Any help?

Thanks.

Thanks a lot.
