Icon selector constantly moving to the left, suspecting faulty D-PAD
When I boot up my DS, the icon selector immediately starts to scroll to the left indefinitely until I turn off the system. I believe it is a hardware problem because it happens in games as well as the overall DS OS. Its possible that one of the switches on the D-PAD is permanently pressed down, though that is just a theory as I do not know the details of the hardware myself. When I move the analog or dpad, I can control the icon box, but when I let go it goes back to the left indefinitely.
What should I do to correct this?
