I bought a 3'' happ trackball new a little over a year ago, along with a ps2/usb mouse wiring harness for it. It doesn't get a lot of use, but has worked perfectly until recently. Out of the blue the X-axis on the trackball has stopped working and I have no idea what happened. My cabinet sits in a mostly unused room and I'm the only one that plays on it and since I live by myself I know no one else could of gotten to it.
Anyways, the vertical axis is no longer working. I've taken the trackball apart and everything appears to be normal, no noticable cut wire or short in the wiring. I also tried it in both usb and ps/2 mode with the same result. The horizontal axis still works fine, as do the mouse buttons.
Anyone have any ideas of what I should try? Do these happen to have a warranty longer then 1 year?
