Question about Denon AVR-485 Receiver

Center Channel problem!!!

I took it out of storage the other day and now am having a center channel issue. It sounds as if it is scratchy, almost like a cross somewhere. I have changed speakers and wires but no change. It does it thru all feeds to include FM broadcasts. The louder the worst it gets! I really can't justify spending 69 dollars just to be told it would cost 600 to fix! PLEASE HELP!!!

    It makes the sound no matter what...Like a pre amp problem or an amp problem...

  • LAROUX Jan 26, 2008

    Its all hooked up correctly and have swapped speakers out. It will play all channels at once also...Tried to use a different ground as well from another channel just to see if the ground was good.

  • LAROUX Jan 26, 2008

    yea, tried different speakers and wiring and even took the silly thing apart and wired directly to the board to make sure it wasn't a faulty connection...

  • LAROUX Jan 26, 2008

    No, it does it at all times, even during a movie...

  • LAROUX Jan 27, 2008

    Yes, its a bad channel do you have a solution?

Sound center


Replace center channel speaker with known good one. If no longer scratchy then the voice coil of removed unit is rubbing against the magnet pole and the speaker needs to be replaced. If the replacement speaker also sounds bad, then the amp for the center channel needs repair.

It wouldn't be your output transistors. If they go bad they blow the fuse. Sounds like a speaker relay problem. Have you checked the solder connections on the relays? They sometimes break down. If that doesn't help, I would replace the relay. Center channel goes through RY501. Sony p/n: 1-755-170-11.

Can a power conditioner improve distortion sound on center channel speaker? I have a Pioneer vsx 1020K receiver and I am only having a problem with the center channel. At first I thought the problem was...


First; power conditioner won't do anything for your issue. It's not crosstalk (unless it's a wireless spkr) On your sub are cables mark + & - ? If so make sure they're attached accordingly to back of receiver/amp. Your distortion sounds like a phase issue. I'm also curious how store performed diagnostics?

Onkyo TX-DS696 receiver center channel not working


Can you say explicitly that the Center Channel speaker is defined as something other than NONE?

And how does dialog sound? If it sounds ok you're routing it to the front speakers. This is from the manual...

"For ideal Surround effects, all speakers should be installed. If a
center speaker or subwoofer is not connected, the sound from the unused channel is properly distributed to the connected speakers in order to produce the best Surround sound possible."

Center channel audio distortion and noise


I have similar problem with my Onkyo Tx-SR600. It only happens when it's in surround mode. When switch to Stereo or Direct, the scratchiness go away. Still trying to find a solution to this problem.

Center Channel not working on pioneer vsx-d608


Be sure the sound source has a center channel output ie. not a 2 channel source only, try the test tone setup for 5 or 6 channel balance, if no sound from the center channel still then it is looking like maybe the center channel is blown.

Center channel


Back to basic to advance:
Be sure you have all speakers connected correctly behind the receiver.If you center channel don't have any sound,it could be 7 different issues,but you could try to just hook up your center channel to either the right or the left speaker output to be sure the center channel speaker does work.
Check your the speaker wiring tip(if there is any),i will use just the speaker wire go straight to the center speaker output,go to the receiver to change it to pro-logic or dolby digital and of course you should put in a dvd in the dvd player to have a good quality movie to play the dialogue through the center channel for you test.
If you have tried the above step and still have no sound,you might consider hiring a troubleshooting master to take care of your issue.

Center channel turns scratchy.


Sorry to inform you, The driver transistors or IC is going bad, or there might be a poor solder connection on the center channel Amp. If you know how to solder, you may be able to poke around at the center channel amp circuit, with a wooden or plastic tool, and maybe see where the bad connection(s) are. To get a shop to looki at this unit, may not pay, but that is all up to you, on how much you paid for the unit, and how much your willing to pay to get it fixed. Read this great article and see if it helps you to decide. http://www.techlore.com/article/10602/How-to-Determine-if-you-Should-Repair-a-Broken-Device/ Good Luck Please do not forget to rate this thread.
