I need help.

I have a Razer Blade 15 mid 19 advance model but my screen doesn't work. It started as screen flickering and a few months later the screen didn't work at all. I bought it at a microsoft store in the us but I don't live there so using the warranty has been impossible. But I am going to the us soon but then saw all microsoft stores closed down and I have been trying to deal with the warranty company and it has been impossible. I need to fix my laptop because I use it for school and I don't know where to fix it can someone help please.
