Q: My new iPhone 6 plus just went to a black screen and will not turn back on. If you hit the home button for siri to come on it still works, and if you plug it into the wall it makes the vibrate noise. The screen just won't turn on.

I was looking up a song on the internet, and my internet was being slow, so i was going to the settings to turn internet/wifi off so i could use data. When i did that the screen just went completely black. I didnt know what happened so i plugged it into a circuit into the wall to see if it needed charging. It made the buzz noise when i plugged it into the charger, and siri still works if you hold the home button down. I don't know what to do to get it to turn back on... If anyone knows what to do please help. thanks !
