Black leaves...new to orchids

[Miyabi]

I live in Florida. I had taken my orchid to be re-potted. After, I decide to leave the orchid in the car while I went to the gym. When I returned several of the leaves turned black. I think the leaves are sunburned. Is there any thing I can do to save them?

Boy those calories are a lot harder to burn then the leaves are huh? You got any pics? If they are severely burned I would just cut them. What type of orchid is it?
Welcome to the board by the way.
