I do not normally send people to Youtube to get an answer, but this 11:35 Min Video explains in a short time what would take me 5 pages to type, and will do a better job of communicating the answer step by step. YES, she is annoying, but effective.
If you try what is in the video and it does not work, you will need to get Repair service.
