Replace the backlight circuit with a backlight circuit on the old screen. This will solve the problem temporarily.

If the Apple logo screen has normal brightness compared to a dimmer screen, the problem is with the light sensor. Remove and install the camera, speakers, and light sensor properly to fix it.
