What’s the Best Solution for Screen Flickering Issues? Need Help from a Dell Laptop Service Center

I’ve been facing persistent screen flickering on my Dell laptop, and it’s disrupting my work. I’ve tried basic troubleshooting like updating drivers and adjusting display settings, but the issue persists. Has anyone resolved this problem successfully? Should I visit a Dell laptop service center for professional help, or is there something else I can try before that? Any insights or experiences would be greatly appreciated!
