You need to unplug the battery then plug it back in to ensure the phone is switched off then you can plug in a replacement screen and turn on the phone. It should show display after that. If the screen is plugged in while the phone is still turned on I don’t think there will be display on the screen until you hard reset the phone. If no good still inspect around the screen connector on the board for any pry damage which are missing or dislodged components.
Hi Mate - did you ever get to the bottom of this? Exact same issue. My screen however shows a crack when I hold it at an angle and I can see it underneath the glass so I’m assuming my phone’s display isn’t showing anything due to this. Waiting on a replacement currently and hoping this is the cause but if not, I’m stumped like you
Hi Erik, I am having this same issue, any success on the second screen?
