Tried replacing power button, screen is now black but phone working.
Yesterday I tried replacing the power button for my iphone 4s, but I faced some problems after reassembling it. The screen doesn't turn on, not at all. I'm not sure what the problem is, I've tried dissasembling and reassembling it again, but still nothing. The phone itself seems to be functioning, for example when plugging it in it starts vibrating. I've managed to enter DFU mode and I'm currently restoring it, but the screen is still not turning on at all.
Is this a good question?
