I have been having random Green screen issues for some reason. I use my laptop daily and it works just fine for the first 6-8 hrs of usage but after that, I keep getting screen flickering randomly and it is not continuous it keeps going and coming back randomly.

Here is the video of what it looks like. I saw some guy commenting that connect some monitor to check if it is a screen issue or GPU but I don't have any space monitors so I tried it with my phone idk if it works.
I gave it for repair and they said it is fixed but clearly not so idk what the problem is. It works fine for a couple of hours then suddenly this keeps happening.
If anyone knows what this is about please help.
Thanks.

Welcome to the forums, newcomer!

You will need to connect an external monitor to your laptop to rule out a bad display on your laptop or if it's a bad GPU on the laptop. If the issue crops up after a number of hours of use, then the backlight panel(on the laptop) needs replacing but please use an external monitor before you go and waste money without verifying that the GPU isn't saying goodbye.

Source a monitor from your friend or neighbor or take your laptop over to your friend or neighbor's house.

Ohk Thanks a lot of your reply! I'll do that before making any decisions on changing the display. The problem is the issue randomly pops up after a lot of hours so I guess I'll have to actively go and keep working on the laptop for few hours with external display.
Also, can you tell what might have caused this issue? It was working fine for like almost 3 years now. I wanna know if I did something that led to this or it is just my laptop getting old.
Thnx again for your support

Bro I have the exact same problem on the same model of notebook as yours, how did you solve it? The technician advised me to change the screen but the problem seems to me to be the processor as it only occurs after some time of use.
