NS-HT511 - Buzzing noise coming from Sub-Woofer

Greetings all.

 

I get a loud buzz/hum sound when I plug in my sub-woofer. I tried a different outlet with the same results.

Otherwise the unit performs flawlessly. Any assistance would be appreciated.

Hello mg2112,

Welcome to Community@Insignia™!

More information would be helpful:

  • Is the hum continuous or intermittent? 
  • Does it occur in all viewing modes (e.g., during cable/satellite viewing, gaming, DVD/Blu-ray viewing, etc.)?
  • How is your home theater system connected to your TV?
  • What other components are connected to your receiver and by what means (e.g., component, HDMI, etc.)?

Any additional information you can provide (more is better) will help us in our research.


Regards,
John

Hello John and Happy New Year

 

The hum/buzz is constant when ever the  sub-woofer is powered up.

Yes - in all viewing modes.

My NS-HT511 is connected to my TV by HDMI.

The only other device connected to my TV is a Comcast Cable Box which is also

connecetd via HDMI.

 

The other speakers are fine. I tried a different power strip and outlet but the hum/buzz remained.

The sub-woofer adds great bass but the hum/buzz is a real killer.

 

Thanks

Hello again mg21112,

Thank you for your New Year's wishes. I sometimes get all businesslike and forget the amenities. I hope the New Year brings you joy and prosperity!

 

I should have asked before and was remiss: what is the brand and model number of your TV?


Regards,
John

Hello mg2112,

 

I would suggest checking the connection between the receiver and the sub, make sure that the cable is firm connected as this could cause the buzzing noise. If this is not the issue then it is possible that there is a hardware issue with the sub and as a result I would suggest taking the unit, along with the receipt, to the place of purchase to obtain service. The NS-HT511 has a one year warranty from the date of purchase.
