i sight not working

How did you realize it stopped working? Did you open up Photo Booth one day and notice nothing showed up?
 
it worked for the first month but it stoped working it is an internal one

I will answer your question if you can answer mine:

My car worked perfectly for the first month but it stopped working. It is a black one.

Now, what, exactly and specifically, is the cause of my car not working, and how, exactly and specifically, do I fix it?

Are you starting to see how answering your question is virtually impossible with the crap-tastically little information you've given us?
