Hello. Initially, I got this AVR of ebay with faulty center channel. Now it works ok, but from some reason when I change channels on my satellite receiver or inputs from SAT/CBL to NET for example, I hear this very annoying popping sound coming from all connected speakers. This noise can be also heard when: 1.Navigate through folders on my media center PC 2.When I power it off - here, the popping sound is even more loud. Does anyone know, what could cause this issue? Here is a short video where you can hear the popping sound while I switch it off. www.dropbox.com/s/zwb44ijwhdrunze/Plik%2009.08.2016%2C%2016%2020%2003.mov?dl=0

If you have a DMM check and see if there is any DC voltage on any of the speaker outs.

Ok, so I've done some tests and in the moment where I hear this popping sound,I was getting between -55 and 110mV DC going to the speaker. Hope that helps.

Try disconnecting the center speaker. If it still pops see if you can turn off the center channel in the menu.

Quick update: I've recently fixed Onkyo TX-SR333 and this model is doing exactly same thing, so I guess, the problem lies somewhere else.
