DISPLAY ISSUE ON MY LAPTOP

[Chaos2000]

Hi, so I have been facing this issue for about 5 days or so. I have noticed black,white and pink band lines appearing on the top part of my laptop screen and it flickers collectively like a unit. My laptop is an Asus TUF A15( Ryzen 7 4800H, RTX 2060) variant,which I had bought on the 9th of November last year. So to provide the basic idea, my laptop has a refresh rate of 144 hz and when it's set on that, these lines occur, on coming across various solutions on the internet ,I tried to switch my refresh rate to 60 hz and the flickering stopped temporarily. But after 10 mins or so, it started acting like the former. There is no solution on the internet based on my problem. I have also attached a picture of the problem and hope it's of use.
Thanks in advance.

If you bought your laptop on the 9th of November last year then it is still under guarantee so I would take it back. Laptops are notoriously difficult to repair. If the graphics is a separate pluggable card then you could replace that but that is very unlikely. the only other things you could try is re-seating the memory or a reinstall from scratch.
