I don’t know y, but my guitar doesn’t work. All the buttons work except for the green button. Its sorta like the censer is jammed. It wouldn’t let me select anything with it, so i went into a song with my normal controller and switched to the guitar and i found out that it was registering the green button being held down the entire time and i wasn’t hitting a single button. The button still can be pressed down like all the other buttons but it won’t work. Does anyone know how to fix this? And my warranty is over, so i was wondering if there is anyway of fixing this without buying a new guitar. Thanks.
