it is a pebble blue galaxy s3 from verizon. i replaced the screen and now the lcd won't light up. the screen was attached to the phone with a small copper colored ribbon in the bottom right corner of the phone. i removed some of the glass when i pulled off the ribbon. is there a way to fix it?

Look on the website iFixit

Welcome to the forums!

Do you mean that you replaced the glass (the outer layer) or that you replaced the whole screen (glass + digitizer + AMOLED display)?
If the latter, did you replace the complete screen assembly (including the front frame)?
Did you use a brand new part?
It sounds like you didn't hook something up correctly but it's hard to say without more information.

I replace glass for the Galaxy S3 all the time, and I've been doing fine. I also have succeeded in replacing the glass on the Note 2 as well. However, I find some of Galaxy Note 2 LEDs don't work after a glass replacement—indicating I must have caused some damages to the LED.

I don't see any cracks, and I only apply 70 °C of heat to loosen the adhesive. And, I use the trusted iFixit spudger to remove it with the same method that I apply to the Galaxy S3—but I find that 3 out 10 times, I will have a problem with the display.
