You could try PRAM and SMC resets. I doubt those would do much, but it’s worth a shot. Since your computer is only a few months old, you should still be within Apple’s 3 month warranty period. I would take it to an Apple store, they will probably replace it free of charge if they can’t fix it. Taking it apart now would ruin any kind of warranty you would have. To me it looks like a loose display connector, or a chip is coming off the board.
