My Velodyne FSR 10B6 sub was working for about six hours and suddenly made a cracking sound then the sound stop but the subwoofer power LED still shows Green. I turn it off from the wall socket and after about 3 mins, turned it back on. Now the Subwoofer power LED is green but when I connect an audio jack using line in, there is no sound from the Subwoofer. Please, I need help. Thanks
