Touchscreen not working, touch screen wire burnt

Hi, my XPS 15 9530 touch screen is not working anymore. The wire for the touch screen which emanates from the display panel and goes into the motherboard seems to have burnt at a point. (pic: https://goo.gl/photos/5Y9NfXnqpM5zYWpP9) I am not sure why it burnt suddenly.

Is there way I can change this wire without replacing the whole display unit?

Any help or suggestion is highly appreciated.

Thanks,

(ps: I asked the Dell support and they told that the whole display assembly would have to be changed. TBH I don't trust Dell tech support much)
