@saadali70418 not turning on or not showing anything? Does it vibrate when you turn it on? It is possible that this is simply a broken display. It is also possible that this is something that damaged some of the internal parts. We will not know until you open it up and start evaluating for some damage.
Use something like this guide [guide|136623] to get into your phone. If you find something that looks odd etc. you can always post images of that with your Question. That way we can see what you see.
