Macbook Pro 13-inch 2016 screen distortions on opening and closing screen hinge

I've had the MacBook about 3 years, and out of nowhere (no damage) the images on the display now become distorted with neon colors and what look like "negative" color images at times. It seems to only occur when the screen is opened up to various hinge angles. (It all looks normal, for instance, when the screen is only opened about 30 degrees, but if I open it, say 45 degrees or more, it starts to glitch. I've rebooted in safe mode and it looks the same. What else can I try??? Do I need to bring it in? It's running Catalina Version 10.15.6. (Seems like a hardware problem, owing to the hinge angle thing).
