I just replaced my lower and upper lcd screen on my 3ds. It booted, however the lower screen had a pinkish hue to it. I tried to take it apart again to make sure everything was in place correctly and after plugging everything back in it no longer boots up. The orange charger light turns on however it does not show any other signs of turning on.
Have you tried disassembling so you can see the inside ?
