FAQ's:
Q: What if I try all these steps and it still wont work?
A: If all of the steps here didn't identify the issue and the computer didn't display to an external monitor then we are left with your motherboard being the problem. It should be replaced. You can see an example of a motherboard replacement here; • How To Replace Lenovo ... . Let me know if you need help finding one or with the install :)
Q: My computer displays to an external monitor but wont display on its own.
A: If your computer displays to an external monitor but will not display to its own LCD, then your most likely looking at a LCD or an LCD Cable issue. Reseat the cable from both ends. If you need help with that, let me know. If that does not help, replace the LCD Cable and the LCD one at a time to find which one is bad.
