Vertical lines on screen

Hello, to my macbook pro 15 ", vertical lineas appear one on the screen, I have read thereabouts that if I connect it to a television and the same lines go out probably it is the graphical card but in my case it is not like that, does not show these lines in external monitors, which it might be?

They disappear for around 10 minutes and they change color, specially from violet to a light gray

Try re-seating the LCD cables, if that does not fix it you will need to replace the LCD or top case assembly. Has it been recently dropped or damaged?

Another thing, sometimes the lines disappear, do you think this might be something of the LCD cables or more just like a damage LCD panel?

Do they completely disappear, or just partially? Post a picture.
