My screen is black but the phonee is powered on

[Android Central Question]

It's an old phone it worked this morning charged and now it wont work

Welcome to Android Central! Which phone? Does the phone ring if you call it, or does it make notification sounds (like from receiving a text)? If so, then the screen has failed and would need to be replaced. But if the phone makes no sound at all, then the battery or motherboard might have failed. Is the battery user-removable?
