MacBook Pro Broken Display? (Less than a month owning it)

I bought this MacBook Pro less than a month ago. This morning the screen randomly flickered and now I have these permanent multi coloured horizontal and vertical lines on my screen.

I have AppleCare and it’s under warranty but I’m wondering is there anyway to fix this without having to go into the store and hope they cover me for whatever is wrong with it?? I’ve tried pretty much every remedy I’ve seen online so far
