I pad black screen tried rebooting same problem

Let it charge for at least 30-45 minutes, then, while still plugged in, try a forced restart as per these instructions:--> Force restart iPad .

If the issue persists, it could be a hardare (screen? battery? other ointernal component?) failure but we, just users like you, cannot diagnose that issue remotely, sorry.

I suggest that you make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> https://locate.apple.com/choose-country-region . After checking it out, they'll give you all the available options.
