Backlight often burns out when replacing the screen. Even with iPhone turned off, there is battery voltage going straight to LCD connector. That’s why you always want to unplug the battery before doing anything else.  When unplugging the lcd, if it crosses the pins from backlight to ground you are creating a short that immediately kills filter.

There are also random backlight failures. Burned filter, bad booster chip, short on capacitor, bad diodes. When the filter burns out often it burns the pad that it sits on. At that point it’s necessary to run a jumper wire from another component that has the signal for backlight fuse. This is a delicate operation and a good repair to show microsoldering skills.
