I just poured some water down my TV...now what do I do?

I was watering my plants and some water got on the TV. Some if poured down the vents at the back of the television. It is a 32" flat screen (or is it flat tube? It's the size of a regular TV, only with a flat screen, it is not super thin).

It just happened so there aren't any huge problems yet, but the picture does occasionally change colors.

Any suggestions on what I can do before I end up paying some $200 to fix it?

Thanks.
