The line indicates the screen is defective. It will have to be replaced. If it is under warranty the manufacturer will replace it. They may replace it even if out of warranty. You might find a new screen on ebay and replace it yourself. Good luck.

If this is a touch screen it is broken. It is probably not cost effective to replace the screen.

This is quite a common problem but it is hard to say what is causing it. Sometimes it is "dead pixels" like what you got on a tv screen if you leave it paused on a channel for hours. OR it could be the processor trying to keep up with you. If you can afford to - try and restore the device and see if the line is still there and let me know.

Try resetting your Kindle by pressing and holding the power switch for 20 seconds - if this doesn't help, then you may need to contact Kindle Support for help with getting a physical repair done.

Try to hold the slide key for 15 sec. It will reboot your kindle. If black patch is not gone even after that, It's a hw issue. Screen might require to be changed. If it's in warranty Amazon will do it free. That's what i have heard.
