On the first minute of system boot, screen becomes really weird. Sometimes screen displays black-white strips with an anormal light adjustment. Sometimes screen dim changes without a reason. When first error happens, if I tilt the display a bit, error goes away. Or if I apply pressure on the case near the display, error goes away too.
Probably I couldn't say it very well but I can record a video of it if you want.
Also these doesn't happen after 1 minutes of the boot. Only happens again when I'm playing a game with blacks and whites together. I think this is something with pins of the display but I'm not sure.
Also I can't get the laptop to service since we are in lockdown and I don't have any other laptop.
