Question Laptop Display not working but external display working properly.

[Anujsup]

Hi, I have a Dell Latitude E6430 laptop. Actually a month ago the hinges got broked and yesterday the display wire which passes through the hinges got broked and a small amount of smoke came from the wire causing the display getting off. I then tried to connect my laptop to a external display and the laptop was working as usual.So I called the technician and as he opened the laptop he told the wire through the motherboard has burnt causing a black burnt mark on the motherboard and the motherboard whole needs to be changed!!
Guys help me out!
