How can i fix a wet monitor?

I own a NEC Multisync XV17+
Due to events that i'd rather not comment on,water leaked inside the monitor through the top(i'd estimate less than 50ml).It stopped working.It didn't react at all for about 2 weeks.Then it started working again,but now the image "dances"especially around the edges.Working on the geometry has no effect,as the image constantly warps.It's not serious,but it's worrying.Amother problem is that now its pretty dark.Any ideas?..Anybody?..Please?
