I’ve been struggling with getting my iPhone 7 Plus screen to work with iFixit for months. I got a screen from them and put it in, and the device would turn on, the touchscreen would work, and I’d even get notifications. But the screen was completely black minus a small amount of backlight. Now I got another new screen from iFixit in hopes they just sent me a bad one. I put it in and now it doesn’t work whatsoever. Help???
Sounds like a possible backlight issue. I would suggest taking your phone in a dark environment and shine a bright light to the screen, if you see a very dimmed out image when toggling power or home button to turn on the screen that would confirm the backlight fault.
