The power transfomer has a loose lamination in it. Gnerally too expensive to replace... check all the mounting screws to it are tight, sometimes a washer under 1 corner may help to rid the buz. ..it may be the standby transfomer also, These can be replaced for much less than a mains transformer.

I have solved this sometimes in the past by giving the laminations of the transformer a strategic wack with a hammer. .

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

The 3 front speakers have started to buzz. When I unplug them in moves to the rear 2 speakers. I orginally thought it was the speakers so I got new ones, same problem. Not sure if it is my reciever getting...


This is a grounding issue either between pieces of equipment or inside the receiver itself.
There are other possible causes, but this will almost always be a grounding issue.
I recommend unplugging everything and hooking it up piece by piece till the buzz return to isolate the issue.
IE - start with nothing but the receiver and speakers hooked up. Turn on the radio. If the speakers buzz, the receiver has an issue and needs to be repaired or replaced.

If there's no buzz, hook up the DVD player. If the buzz returns, there's some issue between the DVD and the receiver....
If the buzz hasn't returned, hook up the.....<insert name of next piece of equipment here>
you get the idea.

I recently bought a Vizio television Model Number Vizio e370vl and I have been experiencing a buzzing background noise whenever I have sound coming through the tv speakers. Be it my satellite reciever...


Exact same problem, buzz was not overwhelming but non theless there. Tried antenna, dish, dvd, another persons house and buzz remained.Complained to Vizio, tech cam out and replaced mainboard I think it was. Bahm,its fixed. Would have tried returning to Walmart but figured another new onemight buzz as well. Tell support line you always have the buzz no matter whatthe input (dish, antenna, dvd player). Windings in power supply coils have air gapsthat create the buzz I read somewhere. Good Luck

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

Flashing protect


the protector comes on to keep the amp from further damaging itself or the speakers. The buzz you heard was probably 60HZ line buzz from the main DC supply conducting full current through one of your speakers through a damaged amplifier transistor. Your stereo will need professional repair. The protect circuit basically opens the speaker relay (and sometimes shuts down the unit) to prevent this DC voltage and current from getting to your speakers until the problem is corrected.

Constant Buzz coming from SX-255r


Power source harmonics. Or its power supply regulation. Check also if input line is touching something.

Buzz in speakers


Not sure what you mean by "buzz" but this sounds like capacitor issues, take it apart if your able and look for caps that are bulged on the top and replace if you find some

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.
