I have recently done a screen replacement on an iphone 7 and the screen was working fine till the home button stopped when rebooted the screen died and only the back-light was on no image or apple logo on boot I can tell it works because I flick the silent switch and the phone vibrates. I have also tried with a new screen and no luck. Please help this phone is for a client and I need it to be fixed soon
If you are sure it’s not a screen problem next step would be to diode the LCD connector and compare to a known good board or board view software.
