Jeremy,

Read one of my posts:
I used a hairdryer and blew hot air into the grill on the bottom of the subwoofer enclosure which reduced the delay time from ~1hr to 5 minutes. (The high pitched noise was still there for about 1-2 minutes)

SOURCE: Three electrical wall outlets do not have power

Hello

One of the outlets that is not working has a wire that has come off. It is probabluy the white wire, but could be the black one. Make sure the breaker is off for that circuit and take off the cover and loosen the screws holding the outlet to the box. Be careful, there still could be power inside even though the breaker is off. There could be another circuit feeding through the box that is not part of the outlet you are working on. You should probably get a licensed electrician. If you are handy and have a tester yiu could do it yourself.

No sound output from my JBL Cinema SB400, tried Bluetooth and HDMI also optical. It was fine yesterday and I turn it on and just no sound what so ever. Can anyone help?


Does the power light come on? If not, check the power cord and power outlet on the wall. Maybe plug in a table lamp to the wall power outlet to make sure the outlet is working. If the power light is on, check the Mute button on your JBL remote control. Also check the Mute button on your TV if sound and picture go through the TV first.
We had a Harman Kardon soundbar (model SB30) made by the same company as your JBL. It worked great for a few months. Then there were a couple of funny high-pitched sounds that stopped when we turned the soundbar off and back on. Then a day or two later we truned on the soundbar and it was completely dead - no sound at all. Harmon/JBL replaced the soundbar under warranty with a refurbished one which lasted about two weeks and dies the same as the first one. Finally, they replaced the second one with a higher model (the SB35) which is still working, although it occasionally makes a rapid clicking noise for a moment here & there.

My avs 2000 makes a load hum


One of the 'cons' of the AVS 2000 is that it makes an audible 'hum' when switched on that can be heard during quieter moments. This shouldn't be overly loud though - If it is, I'd take the unit back for replacement / repair.

How do I eliminate the humming on my Vizio VHT-510 system


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.

    • 2
      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.

    • 5
      Plug the subwoofer into its own surge protector and connect the surge protector to a different wall outlet than the AV receiver uses.

    • 6
      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.

Benwin 5.1 surround sound system Humming loudly without anything pluged into it!!!


It is sad your having a problem with your
Benwin 5.1 surround sound system
If humming can be heard on all speakers, then it could probably

be on the power supply.


If it is only on the main SUB unit, then it could be the amp itself.

But check for power supply capacitors that supplies voltages to the

amps.Check for amp output DC voltages too.

My amplifier is making a very loud humming noise


Are you able to turn the hum up and down.If you can't then you have a leaky filter in your power supply.If you can turn it up and down then it sounds like one of your grounds are open.
