Humming noise is usually a sign of a roving fan and this humming noise comes when the fan is moving with difficulty all you have to do is get a repair personnel to service the unit and is not enough to get the unit replaced.
Hope this solution has been helpful?
Happy new year

Speakers are making a humming noise


If the noise is accross all channels then it's most likely the large electroltic capacitors in the power supply. These filter out the mains hum 50/60hz. There might be two or more they will be the biggest! Even if you can determine only one has gone, it's best to replace them all.

How do i stop the humming sound that comes out my speakers when the system is on?


try investing in a good noise filter or a better surge protector as the noise could be coming for a subsandard power supply

The humming comes from the speakers and is very low and doesn't increase with the volume.It doesn't really bother much, just during quite times of a movie.


does the hum comes in all input? if yes, check proper earth gounding from wall outlet and if ok check filter capacitor in the power supply circuit. If not in all input, check hook up wire for that input causing the humming noise, could be a bad hook-up wire only. Thanks :)

Harmon Kardon AVR220 Humming noise


The most frequent cause of a "humming noise" in electrical components is called a "ground loop". If you want an indebth discussion of just what this is, you may go to this link:

http://en.wikipedia.org/wiki/Ground_loop_(electricity)

If, on the other hand, all you want to do is stop the humming, you may be interested in the discussion here:

http://forum.ecoustics.com/bbs/messages/1/130397.html#

No need for me to reiterate all that is said in the above discusssion. Try all of the suggestions made. Good luck.

Hope this helps.

Humming noise


Usually Humming noises come from frequency interferance.  In this case it is being caused by your input sources.  A smiply solution is to replace the cables and or seperate the source cables away from any electircal cords or sources.
