Screen won't come on - have been to repair store 3 times
My S5 screen won't come on. The lights at the bottom light up, the indicator light at the top will light up, but the screen itself won't turn on. Sometimes when I take the battery out and reboot it, it will but not every time. That also sometimes works when I plug it in, but again not always. I've taken it into Sprint three times since I have insurance on it. They've done a soft reset and did something to a feed on the screen, but nothing has worked. Does anyone know if this is a software or hardware issue? Also, how many times do I have to take this phone in before Sprint will actually acknowledge it's screwed up and replace it?
