Dell Vostro 1400 LCD Showing Black Screen

\015 Hi...My Dell Vostro 1400 laptop is showing a black screen and nothing\015\012else. I connected the laptop to an external monitor via VGA and the\015\012display showed there. Also The FN Function button to brighten or darken\015\012the screen works.I read online that there was an NVIDIA GPU defect for several Dell laptops and I believe this may be the case with my own.Could anyone suggest how to fix this? I really\015\012would hate to have to get another laptop as this one is only about 1\015\012year and a half old.\015

Answers :

If you connected the laptop to an external monitor via VGA and the\015\012display, then it is not "an NVIDIA GPU defect" .

The video chipset connected to the LCD screen is the same connected to the external VGA port, and is working fine since picture is OK on monitor.

More likely the problem is either LCD ribbon cable, or LCD display, the fact that the backlight is working means that the inverter is also working.
Whoever facing problem with Dell display, GPU stuffs and have already expired your warranty, you can ask dell representative to purchase an extended warranty. Under that warranty they replace the main board. It costs around $100.
