sometimes when you pull off the broken screen, you can accidently tear off a filter. there are many of them attached to the main logic board between the various connectors. They are barely visible to the naked eye and you wouldn't know that the damage was done if you don't have a microscope. If you get aggressive with a spudger and use to much of an angle to pry up the connector, you can do that. use a plastic spudger and keep the spudger as parallel to the phone as possible when removing connectors.

if i were in your situation (and i have been a few times with this same problem) I would:
1. inspect the female connector for the lcd that is on the main logic board under a microscope. sometimes when you take the old part off, it lifts one or more of the connectors and damages it so the new part will not work.
2. if #1 looks ok, I would take off the front camera flex and try the screens without that. sometimes the front camera shorts out during a change and that will prevent the new screen from working properly.

3. if #1 and #2 are ok, i would take out the main logic board and inspect filters that run to the connectors with a microscope. if the battery was still connected during the swap you may have shorted one of the filters out the main logic board. Also, static electricity could do the same thing.

4. if #1,2,3 all look ok, I would replace the phone with one of similar value.

if the phone won't turn on even on a charger, putting a new LCD/Digitizer on it won't fix it. There's something else wrong. Make sure your charger is working properly. assuming it is, i would put in a new charging port and battery to see if that allows the phone to turn on.
