You may have a blown fuse. You can remove the screws and pull off the outter shell. When you look inside, you should see a glass tube which is the fuse. Inside the glass tube there should be a thin wire that is supposed to run all the way across the tube. If that thin wire is broken or the fuse looks burnt, then it should be replaced.
