Hello, I have an iPhone 7 that that turns on and vibrates when i charge it but the screen doesn’t show anything. I have tried replacing the screen (with both apple and 3rd-party parts) and have had no luck. There is no sign of water damage, and the phone is slightly bent. Any advice on how to get the screen to work?
Besides trying screen replacements there’s not much you can do on a DIY basis to troubleshoot a no image or no backlight issue, they’re both pointing to hardware issues needing a board repair by a reputable microsolderer. You can just check with a good light and magnification that the socket pins are in good conditions and there’s nothing like dirt or debree preventing a smooth connector lock.
