My Kindle Paperwhite only shows the text on the top half of the screen. When I press the screen at the bottom it flickers but nothing is shown. I can advance to the next page in an e-book, and it will continue displaying text as if I could see the missing portion on the bottom half of the screen.
To be completely honest, Kindles are so inexpensive that you’re truly better off replacing the entire unit with a new one. Repairing these devices costs the same if not more than what they are worth.
llhurst61, sounds like you will have a bad screen on your Kindle. To replace it, use this guide. The part is available at places like this and many more.
