Fix black screen on Samsung galaxy tab e

Solution
Press the Power button while holding down the Volume Up button and see if you're offered a menu which includes Factory Reset. It's a brutal fix which takes all your personal files to the rubbish tip but if you've tried everything else, it's necessary.

Follow the instructions and to make sure you really want to go through with it, you'll need to scroll using the Volume Down button seven times before you confirm the action.
