Hi, I have a Nintendo 3ds and the down button does not click anymore. I want to know if it’s grave and what can cause it. My X button works also 1 time on 2. Please help me!

You may want to open it up and see if the gaskets are being interfered with at all. There’s a repair guide for that area here: Nintendo 3DS XL Power Button Replacement. See if that helps.
