Screen black but still vibrates
I recently got my phone fixed a couple of days ago and randomly the screen turned black. I did not drop the phone. It isn't water damaged. I searched it up online and there was a forum that instructed me to plug it in to my PC, open up iTunes, and I did as told but my iPhone 6 is still unresponsive. I tried pressing the home and power button at he same time and that didn't work. The lcd isn't broken
Is this a good question?
