It sounds like it still starts up, but the backlight coil and/or IC is shorted, this usually happens if you do not turn the phone off or do not disconnect the battery
I would look into that possibility by turning it on and checking the screen for a image with a flashlight, keep in mind soldering the IC is a PITA, but the coil is a little easier if you use a heatgun

here
is a guide to remove the logicboard to check these chips for visual damage, but remember, they can look fine and still be shorted out, so look with a critical eye, but if they have charring, look into how deep into the chip it is, if it looks to not be so in there, you are probably finefine and can replace that IC alone if you can find it, if it's much deeper, remove them and check the condition of the board

It may also be a good idea to check the traces on the board too, those could be the issue too
As to the shields, note where they go when replacing them

Here is the coil and IC, providing these are at fault

If the coil and IC do not work, try a new screen assembly, and if that does not work, something else shorted in the phone too, and will need better info to help

I would look into that possibility by turning it on and checking the screen for a image with a flashlight, if there is a image, it CAN be fixed, just know it's an absolute PITA to solder these parts, so keep this in mind

The screen assembly is probably fine, it's probably a board issue
It might be a good idea to replace the battery in case the battery shorted too, but this is your call really
