Question about Vizio Vht210 2.1 Home Theater Soundbar With Wireless Subwoofer black
See this instruction and fix it. God bless you
Disconnect the coaxial cable at the back of the satellite receiver or cable box by unscrewing the coupler on the cable end.
Attach the cable to the RF IN jack on a surge protector and tighten the coupler clockwise.
Connect a second coaxial cable from the RF OUT jack on the surge protector to the input on the cable box or satellite receiver. If this stops the hum, congratulations: You're done.
Unplug the subwoofer's electrical cord from the power strip or wall outlet if it is connected to the same circuit as the AV receiver. The amp in the AV receiver and the amp in the subwoofer are in conflict over the grounding of the electrical circuit.
Plug the subwoofer into its own surge protector and connect the surge protector to a different wall outlet than the AV receiver uses.
Disconnect the subwoofer cable from the back of the sub and the AV receiver if all other measures fail to stop the humming. Reverse the plug connections so the plug that had been connected to the receiver is now connected to the subwoofer. Turning the cable around may solve a problem known as ground-loop hum by reversing the shielding wire inside the cable.
