It seems that you have "lost" the backlight power to the screen (assuming that the new screen is the correct one for your particular model laptop (what is the exact model number?) and if it is the correct one if it is OK and not faulty.
(You did have the battery removed from the laptop when you removed/replaced the screen didn’t you?)
-
Not sure re your particular model laptop if this will work as I don’t know what type of lid switch arrangement is in place.
-
-
Try using a reasonably strong magnet and move it around the area of the Power button above the keyboard and check if the screen “turns on”. (With the laptop turned on of course) (Also try moving it along the full length of the bottom case between the top of the keyboard and the back edge of the laptop) if nothing happens near the Power button just in case)
-
-
''If it does'' then the magnet in the lid, usually in the bezel below the screen, above where you place the magnet on the lower case has shifted. You’ll have to open the lid assembly and find and correctly re-position the magnet.
-
-
''If nothing happens when using the magnet,'' then there is either a problem with the power supply for the backlighting or the screen is faulty, (can you try the old screen again to check?)

-
I’m assuming that your laptop uses a magnet in the lid to operate a magnetic switch in the case which sends a signal to the BIOS to ''software'' turn the backlighting on and off depending on the position of the lid.

-
The other scenario is that the backlighting power is routed via a magnetic switch in the lid which actually open the circuit for the power but usually that involves two cables going into the lid (besides WiFi and camera etc) one for video and one for the backlighting and the manual I looked at only said to remove the video cable no mention of the power cable.
