With the laptop on, try shining a flashlight at an angle close to the laptop's screen and check if you can see any images at all.
They will be ''very faint'' if they are there so trying this in a darkened room may help to see them.
''If you can see images'' then there's a backlight problem with the display. This could be a faulty backlight power supply on the motherboard, faulty video cable or a faulty screen.
Hopefully you turned off the laptop and disconnected the battery from the motherboard ''before'' unplugging and plugging in the screen.
Plugging the video cable back in again if the laptop was on or even if it were off and the battery wasn't disconnected, could've damaged the backlight power circuit i.e. blown a fuse on the motherboard if there is one or perhaps even a power mosfet that supplies the backlight power if there isn't a fuse.[br]
