Black screen on my.iPad pro

While I was using my iPad editing some photos using an app the screen went blank and I try to reboot it by pressing the home button and the power button at the same time the logo appeared on the screen followed by a red line going down from The Middle now whenever I charge my iPad I hear the connector working but when I press the home button the color of the screen still black but he has little light on the back ground but no image my question is what is need to be replaced and what's the problem
