Question about Denon AVR-4800 Receiver

Open Question

Center and rear speakers have a static sound coming out of them.

I have a Kenwood unit. I noticed that I had a static sound coming from the center channel. So I thought the center channel was blown. I bought a new center channel and rear speakers. When I hooked them up statuc noise started coming out of center and rear speakers. I tried switching receivers and the problem stopped. When I hooked back up the Kenwood the problem started again. Do you have any suggestions on what possible could be wrong with the Kenwood reciever??

SOURCE: No sound from my brand new speakers

I am assuming you have tried new speakers on used unit on both A & B choices. Have you tried your new speakers with old 2802? If they work OK with old unit, you have problem with amplifier in used unit. Take the used 2802 to a reputable shop and have it thoroughly tested. Perhaps it is just a loose connection.

SOURCE: Connecting DVD player to AV receiver

If you've done that already and still no response from your system, I would suggest to take back to the place where you bought it and ask them to check it for you. Tell them that you follow the user's manual to the "T" but still unable to make it work.
Good Luck.

SOURCE: left channel not working

Hi,

Thanks, yesterday i tried changing the speakers from right to left, the problem still remained on the speaker getting connected to the right channel. Later i pulled out the speaker wires from the reciver's end for the right channel, cut them and pulled out new strings from the insulation, twisted them and inserted, the speaker is working fine, though not 100% but close to left channel. I guess the problem was old strings in the wire which had got over twisted and were not parallel to each other.

regards
Swamy

SOURCE: 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.
Let me know what you need!

Kenwood vr606 reciever shutting off subwoofer and centre speaker simultaneously after few minutes/seconds of powering on. WHat's the cause?


The receiver's out put sections are grouped in pairs. Front left and right in one output, rear left and right in second output, and center channel and sub output on the third. Sounds like a semiconductor or semiconductors have gone bad in the center & sub output.

I have an old Chevy and I'm trying to hook up my Kenwood kdc-138 stereo. I have the red wire connect to the red ignition wire and black wire to ground. I have the yellow wire hokoed up to the ignition...


The fact that your speakers have only one wire, indicates that they are the old negative ground type. You will have to buy new speakers, or try and connect the negative wires of your speaker wires from the radio to the car body (chassis) and try that. Normally you will get a bit of static when you start your engine

No sound output from Center and Surround speakers


the only time the center and surround speakers put out sound is when it has a surround sound source such as a dvd etc. and only certain sounds come from them as well.

Garbled / feedback sounds from powered subwoofer


The surround processing portion of the unit has a problem. In either stereo or direct mode, the digital procesing is bypassed. This could be just the surround processing IC, but that IC may not be available as a separate part. I would suggest that you bring this unit to an authorized Onkyo service center for an estimate.

Kenwood VR6070 speaker/amp problems


unit needs repair. Look at the b speakers. Conect a speaker or two to the B position. If you have no sound than your surrond sound is ok and the unit is bad. Sound comes directly into the b speaker and not threw the surrond system. My 6070 has a cold start up problem. no sound. time to purchase a new one. to costly to repair.

Sound from 4 speakers cut off..


To troubleshoot a speaker system where sound is not issuing from all speakers, please do the following:
  1. Verify that all cables are plugged in correctly. Make sure the rear and/or center/sub audio cable is plugged in to the correct port. On most surround sound cards, the rear audio port is black, the front audio port is green, and the center/sub audio port is orange. If you do not have a surround sound card, make sure you obtain the proper adapter (discussed in the next paragraph) or use surround sound emulation if your speaker system offers it. If you are not sure if you have a surround sound card, please check with the manufacturer of your sound card for details.
  2. Make sure your sound card supports the same amount of channels as your speaker system contains. For 4.1 systems, it should have a front and rear speaker jack on the card. For 5.1 systems, the card should have a front, rear, and center/sub, output. The card should be properly installed and configured. Please contact your sound card manufacturer for details. If you do not have a surround sound capable sound card, you can use the source selector switch or the M3D button on the controller unit (if available). You can also use an adapter to split the signal for the front and rear speakers. This type of adapter is a 3.5mm male to 2-3.5mm female jacks. You can purchase this adapter at your local electronic store. Please refer to your manual if you do not know if your speaker system can emulate surround sound.
  3. Try connecting the speakers to a portable sound device such as a walkman or portable CD player. Plug the speakers into the headphone jack, but make sure the volume is lowered so the speakers are not over powered. You can do this for both the front, rear, center/sub speakers to verify that they work. If the speaker system works on the walkman, then you are experiencing a configuration issue with your sound card. Please contact your sound card manufacturer.
  4. Check the system Volume Control located in the System tray. Make sure that the volumes are at a reasonable level and are not checked for Muting.
