I don't know, maybe you should check the inside if there is any corrosion or damaged parts. I had mine for 11 years and it still worked fine.

Hello. I have a small tablet-like electronic (leapfrog 2) and someone tried to clean it with water and baking soda for some reason. The sound works fine but the screen loads upside down, weirdly pixelated and touchscreen doesn't work. there is still some baking soda left around some buttons. What can I do?
