Dear forum
I have a 2 year old Dell Vostro 3750 laptop. It has a problem in the display. But it works perfectly fine on external display. The laptop screen flickers some time and I get a plain white screen. And it works fine sometime for few minutes.
I tried with a new screen and tried to replace the LCD video ribbon cable that connects the LCD from the mother board. All this trials did not help. Still the same problem continues.
What could be the cause ? Could it be a problem in the motherboard ?
Please help
Thanks
