Phone won't turn off with button

[AC Question]

Last week my phone got wet in rain. It dried out over night and worked fine in the morning but now 1 week later it will not turn off by the button. I m worried if I do get it off I won't get it back on as well.

There may be water damage. See this: http://forums.androidcentral.com/showthread.php?t=477140

On the other hand there may be some other fault, such as with the Power switch.
