I have a gateway NV57H26u laptop Windows 7 Home Premium, service pack 1, 64 bit, Intel 2.30 GHz.

My screen cracked and I replaced the LCD screen. However after replacing. The screen turns on only to display color vertical lines. When I connected my external monitor via VGA cable. I can see the display with no issues.

I tried to update the video settings with no change.

Suggestions and help appreciated

Thanks
 
When you changed the display did you change the cable that connects it or kept the old one? That could be the culprit.

Also, it is completely possible the display is flawed. If that is the case, return it and have them give you another one.
