Having problems with your Computer Monitors ?

Computer boots up but nothing is displayed. Does display through secondary monitor

Answers :

Put your laptop in a bright, bright room or shine a light on the bottom of the screen and make sure that there is really nothing on the screen. Sometimes these lcd look black but there still may be a picture, it is just not being backlit. If you can see something on the dark screen, then you have lost your backlight, which is built into the bottom of the lcd. If there just is nothing there, then this could be a screen failure, inverter failure or primary video circuit. I would lean toward the screen died, But I would also change the inverter while I was at it....they are fairly cheap. Just make sure that the main video plug the runs to the integrated lcd is properly seated or you will not get a picture. Check both ends of the cable, notherboard and back of the screen.
