Replaced Screen, new screen won't turn on.

Have you tried disconnecting the new screen and reconnecting it?

Reviewed the questions in the sidebar for info? When dropped, did the screen black out because it's a clue. Dropping can damage delicate circuit board wiring traces invisible to the naked eye without using a jewellers 10x eye loupe or magnifying glass. Damage may occur anywhere including breaking soft solder joints to render any phone display dead while the rest of the phone may work. Of course, without a screen, a phone is useless. Diy repairs has risks as no one ifs an expert.

I have this same problem. If I plug it in to charge, I hear the noise that it's charging and I can even hear phone calls coming and feel the phone rumble. Despite all this, both the old and new screens are not powering on.

@Will Haskell Did the old screen work before you replaced it with the new one?

@Nicholas Kerns yes it did. There's a chip just above the socket where the screen plugs into the motherboard and this chip has a really large dark area covering it. I took it into a local shop and the guy said it looks like the chip may have fried when I was applying the heat to open the phone... If it helps someone else, here was my method: I turned the phone off and applied the iOpener from iFixit for about 1 minute after microwaving it for 30 seconds like it suggested. I then took a guitar pick thing from iFixit and started tearing through the adhesive but I think I pressed the power button while I was doing this step. My guess is that the phone kicked back on but the chip was hot from the iOpener application and fried.
