I had the same problem. What I did is sent it to Nintendo repair services, and as long as there no big physical damage they'll will fix it for free because it's a system malfunction
The same thing happened to me but I took out the battery for 5 minutes and it work but both screen colors were the wrong color and kept changing every time I move to a different icon the color changes
This may sound ridiculous, this happened to me today and I looked inside it and nothing was wrong. I got upset and kick the back of it and it started working again
