Hi KenB & Plastic, many thanks for the valuable information.

Dear, I have a Vostro 3750 laptop which is 2 years old. It got some flickering flashes on the screen last time but it disappeared after some time. But on next reboot again I got that same flickering flashes but in between I was able to see the screen contents. But after few minutes it become full plain white and could not see any contents any more. When I connect it to an external display it works and I could see the contents. But the laptop screen does not works any more. Any suggestions What could be the common problem ? Could it be some loose contacts in the screen connections or should I replace the screen or could it be a major motherboard issue ? Thanks Jay
