Compaq 510
Laptop Display problem under warrant but no response

I bought Compaq 510 last year and since then there is one or the other problem with the laptop. Everytime I visit the vendor or the HP outlet the dont entertain my complaint and say this needs to be changed that needs to be changed and it will cost that much. There is a problem in my laptop's display for which I approached them twice but they never resolve it. I am enclosing the video clippings for the reference. Please try to resolve it on priority basis as my warrant will expire on 27 th of this month
