Question about Onkyo TX-SR875 Receiver

Loud Buzzing Sound

This morning I turned on the system and a very loud buzzing sound came from the speakers. I was so loud it made me jump right out my seat and my speakers might have been damaged. I turned the volume all the way down and turned it up one notch and the loud buzzing sound came back. This happens with any input I set it to. Anyone know how to fix this?

This may be a power supply failure, and or a short in the output stage, and in the drivers for the output stage.

This is not a repair you can do at home unless you have a lot of experience in troubshooting and analysing problems in power amplifier equipment.

Constant buzzing sound in all speakers


Sounds like either a transformer or amplifier problem. You haven't reversed polarity on the speaker connections? or changed the speaker sizes, Ohms, ect? Probably a resistor, diode, or condenser in the amplifier causing feedback through the speaker system. It's doubtful both speaker coils went out at the same time. Possible, but doubtful.And you mention that the volume "SPIKES" from time to time. Could be as simple as corrosion on the volume "pot". Basically a Rheostat that allows more signal the farther you turn the knob. If so, you can clean that yourself with a spray product available at any Radio Shack. It is for cleaning electonic components and leaves no residue. You could have this checked at any competant electronics shop, but BEWARE, the "Bench Fee" to test may be more than the value of the system. I would ask what the "bench fee" was to determine a problem, and then what the labor costs would be to repair either a transformer or amplifier with resistors, diodes, capacitors, ect. Electronic equipment tends to "break down" over time and use, and sometimes you can replace a component cheaper than repair. If part of a rack system, then you may want to retain this sub-part and repair may be your choice. I would ask about the fees to test, and the costs of labor to repair, before turning it over. How old is the system?

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.

A couple of weeks after initial setup of my brand new Onkyo XT-SR606 receiver, I noticed a loud buzzing noise that starts up approximately 10 min after the receiver is turned on. The buzzing is definitely...


The "buzz" you hear is a power hum made by the power supply transformer. It's technically called "Lamination hum" caused by the revering of electrical current through the power supply transformer. In some cases the hum can vibrate the chassis causing other loose material to vibrate. If you can, go to your dealer and check to see if other units of this same type typically make a hum this loud, and if not, see if he can solve the problem for you.

Loud buzzing at the first volume setting


Check all your wires and make sure that none of the wires that are powering any equipment (including extension cords, power bars, and power cables on the unit itself) are running parallel to any of the audio cables going to your speakers or from your inputs to your unit. This could be what's called AC hum, which is caused when the electrical current causes interference that gets picked up by the audio cables and amplified by your system. Just make sure you move the power cords as far away as possible from the audio cables.
