Anytime I try to use my dsi, it's like I'm pressing down on the right d-pad button. I've bought a new rubber pad, as well as a new d-pad board. I installed both of them, it worked for about a week, and now the problem popped up again. What could the problem be? Could it be something in the motherboard? Thank you in advance!!! :D (I would also like to add that there's no problem with the screen, I've done multiple tests, and it works perfectly fine)
