My 2.1 F&D Subwoofer System suddenly began to give noise like random bass from the woofer. It does so even if the unit is switch off but connected to the power supply. The damn thing can't even be reduced by controlling the volume. All of a sudden goes off like a cannon firing continuously. Could someone please help with what might be the issue?
