The problem is not with the screen. If you turn on your laptop in a dark room and you put a flashlight on your screen, you will get a very faint display. The problem seems to lying with the inverter.
The inverter is a electrical device which 'backlits' the LCD and gives the display. Without the inverter and the bulbs it powers, the screen would be too faint to be seen.
To test if the inverter is defective, just turn on your laptop in a dark space, then put a flashlight on the screen to see if you have a fainted display. If you can see something, it is the inverter which is defective and should be replaced.
If you are handy, you can also remove the screen cover to see if there is a neon like light which lits up behind the LCD. If you can see the light, it means that the inverter is just working fine and that the is with the LCD itself.
Picture of an inverter.
Replacing the inverter:
1. After removing the screen 'cover', locate a small circuit board (usually below the LCD). Unplug the electrical cables and replace.
In your case, as the LCD has been replaced, check if the cables are well connected to both ends of the inverter. If the cables are well connected, consider replacing the inverter.
