Welcome to the community forums.
The best way to isolate the issue of the flickering screen if this is software or hardware issue is by connecting the laptop to an external monitor. See if the flickering will also appear on the external monitor. If you notice that the screen flickers on the laptop's LCD and not on the external monitor. This is a hardware issue. If both display flickers at the same time, this is a software issue.
That is when we want to proceed if the laptop needs replacement parts or not.
