Buzzing/vibration noise from ONYKO TX-SR506 unit

Hi there,

I have recently purchased a ONYKO TX-SR506 amplifier. All speakers are connected but when I switch on the actual unit itself it emits a buzzing/vibrating sound. We have tried moving it but is is still there.

When volume is turned up is covers up the noise but it is still there and is annoying.

    Everything is hooked up but when we turn the unit on it buzes for 5 to 10 minutes before it goes away. Appears to buzz longer each time we turn it on.

The issue is that when you hook up the HDMI connector (Only) from a source into the receiver the subwoofer will produce a audio hum if the source is either not playing or in a pause state you will hear the hum. Once you remove the HDMI connection the humming disappears. Again the UPDATE will reduce it 90% but at a high volume you can still hear the hum come out of the subwoofer and you know that if the customer knows about it they are going to be looking for it after the update. So at this point after the UPDATE you will hear some hum because the receiver is still processing a signal through the system. But at normal listening it's not going to be producing any humming, just your normal bass signal is going to be produced.

If the unit is under warranty, DO NOT open it up. Bring it in for an exchange or warranty service. Explain that the unit makes noise during use and it will be serviced. This could be as simple as a bad connection in the power supply area and you are hearing oscillations or it could be a defective power transformer. Either case will be covered under warranty so there should be no charge to you.

Keep us posted.

My Onkyo TX-SR506 plays cable and CD inputs to zone 2, but DVD won't play. Everything is connected according to the manual and I assigned zone 2 output correctly. What gives?


How are your cable and cd inputs hooked up? Analog connections? Alot of receivers cannot send an audio signal from hdmi inputs to zone 2.

Should i use an amplifier with the txsr506. i dont know if im doing anything right with the receiver. i feel like its two low on volume


It HAS amplifiers. You don't daisy-chain amps.

Get the manual and take some of the gueswork out of the process. Set it up and come back with specific questions.

I have a onkyo tx-sr506 receiver that turns it self off


This unit is in protect mode. This means that a problem was detected and the unit has shutdown to prevent further damage. The most common cause of this is failed output transistors. Plan on $20-$40 for parts for this repair.

I recently purchased a 52 inch LCD. I have


This could be the speakers are vibrating onto the casing and need padding out more to prevent this.If this isnt the case, you may have a sticking coil on one of your speakers..When the sound distorts, remove one speaker in turn to see which one(s) are the offending unit(s) and replace. Is there a buzzing noise coming from the speakers especially in low volume? If so then you may have a faulty capacitor in your power supply producing hum on sound. Hope this helps :)

Alot of loud feedback through speakers, a loud buzzing noise


What sources make it happen or which do not? All buzzing = something in the amplifier end. is it from all speakers or just one?
One external source= RCA cables not grounded. Reconnect them tightly with a twisting motion to wipe off oxidation.

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.
