Mine has also started to make a horrible hissing sound. It also makes it when I use the Bluetooth with no cables connected except the power lead. Also tried it in another room in case it was getting interference from the tv etc. PLEASE HELP!
Sorry, there was a problem. Please try again later.Had the same problem for quite a while, tried everything changing cables, using only Bluetooth, nothing was making a difference, and finally un-screwed the motherboard, unplugged carefully the cables, took a toothbrush and cleaned the whole motherboard with some isopropyl alcohol, put everything back together and it seems to have solved the problem.
Sorry, there was a problem. Please try again later.Mine did the same thing. Called Denon. They had me send to repair shop. Replacing mother board. Expensive but cheaper than replacing and I have been very happy with it for the past 5? years.
Sorry, there was a problem. Please try again later.Mine started off making a bad hissing noise, now its gotten louder. Very annoying
Sorry, there was a problem. Please try again later.Having the same issue. The sound is coming from the subwoofer. It was intermittent at first, now, it’s constant. My guess is: built in obsolescence. Makes no sense that hundreds of people are having the same issue.
