Did you disconnect the battery when you did the screen replacement? You probably blew the backlight circuit, specifically the backlight filter. If you have the right tools, you could probe the backlight circuit to see if that is the problem.

(Hopefully you already tried another screen!)

If the backlight circuit is blown, this will require a micro-soldering repair.
