black screen after screen replace
hello
i have been repairing phones/cameras and anything else i can get my hands on for many years and this is the first phone thats giving me a lot of trouble. i have tried a few different screens and all i get is a black screen. i can see the apple logo when i force a reboot and i had a brief flash on light on the screen when i connected a charger. i have cleaned all the joints and connectors.
anyone have any ideas on any other tricks

This sounds like a issue with the backlight ic on the logic board. I'd wait for others to comment as they probably know more about this kind of issue.

is there any way you can get a light behind the screen? if the backlight burnt out, using a light behind the screen should help figure out if theres nothing showing on the screen or if the backlight is having issues.
