Q: I tried turning the phone on, but all it does is show the apple logo then turn back to a black screen.

My IPhone 6 will not turn on. It was charged then suddenly shut off, now when I try to turn it on nothing appears. But when it is on the charger if I hold the power and home button the apple logo will appear then a few seconds later disappear to a black screen then reappear to the apple logo, and the cycle continues over and over. It never actually turns on though. How do I fix this problem?
