Help With Dell Inspiron 1440 Screen

[Big_Rob]

I recently replaced my screen on my Dell Inspiron 1440. At start up the display lit up but remained black. I connected the laptop ton external display with no issues. I cycled through the internal/external display switch, F1. My laptop screen successfully came on and I was able to log in. I powered the laptop off via the start menu. An hour later when I went to use the laptop, the screen lit up but remained black. Cycling through the internal/external display no longer brings back up the display on the laptop. I have no issue with the external monitor. Can someone please help?

Are you sure that you connected the screen securely? And all of the other connectors securely?
