I kind of had the same problem with my cell phone accidentally being put into the washing machine... I just laid it down somewhere (screen turned down, but I don't think that is possible with ur laptop..) and left it alone for a week (!!!) and after that, it worked like it hadn't been put into the washing machine at all, except for the fact that it was a little cleaner.. ^^
So I hope waiting a little bit will do the trick for you too..!! And otherwise -and if none of the other advises works-, I'll give you my condoleances with the death of your screen..
