My laptop screen has turned negative. it is not in high contrast mode. It is fine with external monitor Also I reconnected the LCD cable but no change. Is it a bad LCD?

If it is negative even on the bios screen, than it is likely a hardware issue.

Try connecting the video out to an external monitor, and seeing if is normal, or a negative. If it is still a negative, than the issue is with the graphics card. If it is limited to the laptop display, and the external display is ok, than the issue is with the laptop display.

RE : Thanks for your replay. I did it, but no change. The screen is negative from the BIOS screen itself. The DELL logo appears negative.

I connected it to an external monitor and it works fine. So I will have to change my laptop display. Thank you.
