I have a Dell Inspiron N5030. The problem I am having is no display on the LCD screen of my laptop. I do get display on an external monitor. The computer boots and acts completely normal when being viewed on an external monitor.
Here is what I have done so far:
1. I replaced the motherboard.
2. I replaced the display cable.
3. I replaced the LCD screen.
After replacing the motherboard, 2 different display cables and LCD screen I still cannot get any video on my LCD screen on the laptop.
Please help if you have any suggestions.
