My 5c wont show display

My phone was working perfectly fine Saturday may 27th. After not using it for a few days just sitting in my bed, i went to charge it up and nothing came on. I plugged it in two different computers and both are recognizing it in iTunes and makes connection sound. The phone itself doesn't vibrate or make the charging sound when plugged in as it should . the screen to my knowledge has never been replaced or tampered with.
