Screen replacement phone shut on to battery sign now completely black
Hello, I just replaced my iPhone 6 plus screen with a screen replacement. I did everything and charged it. It wouldn't come on. I plugged it in again it came on to the red battery charging sign then went back off and I clicked the home a power button and still nothing. What should I do because ik the screen works if it came on. Could it be the fact I haven't charged it in a month and maybe it needs to charge for 2 days?
