lines on laptop screen

Hi! I have a Samsung r580 laptop which is about 11 years old. For the last 6 months there's been "screen top flashing at the bottom" problem. Also I've realized that colors appear more pale on this screen and when i look really closely, i can see vertical stripes of the colors that whatever is...

horizonal lines keep appearing and dissapearing on my asus laptop screen,all my drivers are up to date,and the lines got longer over time(weeks).
