Hp 635 laptop blank screen [Closed]

I tried this method not working for me...first it started where sometimes the screen goes blank at random..and had to shutdown and start again and it will come back on
But then one day it did it again I shut it down start it again but this time it won't come back on
I cannot see a thing..the screen is not completely black..it just lights up..i can increase the birghtness
Tried connecting it to a tv nothing..anyone ?
