Well, I'm at a point not to do. Has come to hand a 17 "from a scrap yard with the intention of replacing the faulty screen HP. The laptop has already more than 10 stripes and is very annoying to work with.
do not know if the change or continue the fight against HP. If the change would serve to prove that the cause is in the screen itself, but on the other hand, might seem to throw in the towel.
wait one day more to see if at the end and the mediation of consumer protection service of my municipality get any positive response from HP. Otherwise proceed to the screen change.
