hello everyone i have probably the weirdest way of having my home theater subwoofer fail on me. ok so i was charging my phone and someone called me so i go to answer it and as soon as i touch the phone i got a strong electric shock from it because i was charged from my carpet. when that happened my subwoofer (that is plugged to a different wall outlet near my phone charger) started humming loud. i dont know why it started humming. I have a samsung ps-aw730 powered subwoofer. what i have done so far: 1. plugged subwoofer to different outlet. no change 2. did a speaker test. no change 3. opened up the SB everything seems ok. no fuses burned or anything. 4. audio wire is good too if you guys can help me out in fixing my sub, that would be greatly appreciated thanks!
