Please see the top of this page. There you'll find a link to orchid diseases. That will tell you what to do.

I am not an expert, but - those brown spots are very light and do not seem wet to me, so I don't think they are a problem. Perhaps too much light? The spotting is either natural, or could also indicate too much light. I've seen this in my 'chids and they are fine. Again, I'm not an expert - maybe others will weigh in.
