Ricky Bobbie, those are very difficult questions to answer. My first suggestion would be to open it up and to take a look always remember that it is tough to say what is non-functional until you take a look at it. It would just be a guess. So take it apart and take a look at it. If you are not sure what to do let us know what you find once it is apart. If you are not well versed in repairing power supplies or any other equipment that may require soldering, I do recommend that you either give it to someone who can do it for you. A new/rebuild one is also not to expensive. Best of luck to you and let us know how it is going.
