Having problems with your PC Laptops ?

Lcd screen is black the computer works fine with a remote monitor. i would like to try and fix it myself as a project.

Answers :

The best thing to do to know where the issue lies is to use a torch and show the light on the screen. This should show you the icons with the desktop. If it does then the back light needs to be replaced. The backlight provides lighting behind the screen so that the desktop is visible.
\015\012If not then the problem is either with the cable or the LCD itself.
\015\012For either case you will have to access the Display. I would recommend you to use a service manual when doing the same.
There may be several problems. Maybe are led's dead or invertor dead.
