  • Stager Dec 31, 2010

    Details please:

    Does the loudness of the hum change with the volume control?
    Is it on all the inputs or only one, left and right or just one side?
    Is it on all, some, one speaker?
    Did you recently move the receiver to a spot near a monitor or other
    item with a large transformer which might be inducing hum at the inputs?

Buzzing is usally AC line noise leaking into an un-shielded cable somewhere or a floating ground. If the AC plug is reversable, try that. Sometimes the buzz is from an attached device. Make sure all audio cables are plugged in tightly at each end and routed away from or at right angles to any power cords and away from other sources of strong magnetic fields like TV's. I've also seen variable track lights induce noise but it's usually minor.



If it still does it with no cables or anything external attached it's an internal problem.

My coleman evcon furnace just hums when i turn it on it doesnt engage the blower or fan thing it a quiet hum... Ready to call for repair but i wondered if there was something i could try..would like h


The hum could just be the control transformer, but that's usually a very light and barely perceptible hum. If its a louder hum, and it stops after a few minutes, the hum could be the blower motor refusing to start for any number of reasons, then cycling on its internal winding thermostat.

I'd call a service tech.

Unplugged computer plugged back up loud humming


The humming could be coming from one of the fans or the disk drive. Sometimes if you just tap the case the humming will quit. If there is a CD in the cd drive sometimes it will hum.

Don't worry about the humming, if it starts clicking, that's when you worry.

you have a ground loop issue you could purchase a ground loop isolator, jensen makes them for about 40 bucks.I have discovered that if you have cable tv, unplug the incoming cable in your cable box and see if hum disappears.

I have Insignia ns-p42q-10a tv, there is a loud hum when the volume is on when you mute the volume it goes away? Any suggestions?


check other inputs AVI, HDMI,,

do you here the hum on all inputs?

The hum maybe from a bad ground loop,, unplug all pluged in inputs, [dvd,games,radio,ect] <--check for hum.

If the hum is gone, plug inputs back in one at a time and test,,

When you find the source of the hum, go get a ground loop isolator to fix.

NAD S300 Amplifer humming


You have either got a bad earth connection, or possibily there's a capacitor failed.
If you can't find a dodgy conection, I would replace the large Electrolytic Capacitors in the power section, they are used to take out 50hz hum in the mains electric, when they go you get that hum coming into your system.

Speaker a and b have humming noise


If it's a loud 60 cycle hum stop running it and have it serviced. This hum can be a shorted output which can send out 50 to 60 volts out to your speakers damaging them.

Amplifiers has a hum


The hum therefore is a generated before it reaches the volume control. Check that all the connects are good, a bad earth will cause a hum. If the hum is in both channels it will be something that is common to both. Electrolytic Capacitors are there to take out hum, so suspect them first!

Hum in the audio - 32'' Proscan 1080i


does the hum occur when playing a dvd or only when watching tv ? if the hum occurs only when watching tv, i would like you to disconnect the cable line from either the wall or the back of the cable box and see if this hum disappears. if the hum disappears call your cable company. you have what is called a " 60 cycle ground loop ". hope this helps.
