Dear All,
my nokia n900 last night went off while it was working very fine without any problems ... some days ago it fell in some water .i dried it but it was working very good since aftr that .. it was almost 10 days ago before last night .. but last night it went off by itself .. now it is not switching on .. when i press the power button , it shows light n on screen i see NOKIA written.. aftr that nothing happens n it goes off ...

is it some os issues ??? do i need to reinstall the firmware ?? or what is it ?? plz help
