Almost dead SL45

Hi all, I have a SL45 dropped in water, the phone didn't work at all for three days, I took it to a siemens center, they told it can't be fixed.

Last night I connected the charger, the LCD went on and it started charging normally. but when I press the power it goes of again, so I have to reconnect the charger..

Can it be fixed?

Thanks all..

Try to open it carefully, clean it with alcool and then dry it well.
