The mouse wheel to my Razer deathadder 2013 broke, and when I scroll, there is no resistance on it, and nothing registers except mouse3. The warranty was gone on it, so i tried to take it apart to see if I could fix it. I looked up a tutorial, and only tutorials for older mice were posted. When I tried to take the circuit board out to take the mouse wheel out, it wouldn't come out becuase it looked like there was a small board keeping the mousewheel in, which was keeping the whole thing inside the mouse case. Any help would be appreciated!
