Question about Clevo MOBINOTE M540N LAPTOP LCD SCREEN 14.0" WXGA GLOSSY CCFL (SUBSTITUTE PART NO.) (22099281498)
When replacing the screen, have you checked the LCD screen cable (the cable connecting the LCD screen to the laptop's motherboard) & made sure it is not damaged or cracked as well?
Did you make sure that all cables are reconnected back tight to where they were connected before disassembling the laptop & replacing the cracked screen?
Can you get image on an external screen connected to the laptop?

If the screen is completely black, the chances are that you forgot to hook the backlight circuit back up after replacing the LCD and hooking up the LCD panel cable.
If the backlight appears to be coming on, double check that the cable is in place and LOCKED at the LCD, and also that it didn't disconnect at the system board end.
After you double check all the connections, if it still isn't working, please tel me the make and model of the LCD screens themselves, and I will look them up and check to make sure the panel you purchased is compatible.
There is a small chance the backlight in the panel you purchased broke in shipping.
