SOURCE: JVC RX-618V SOUND IS MUFFLED

check to see if the radio is clear. If it is it may be the signal going into the amplifier. if it is muffled as well, depending if you have an Equalizer hooked to the unit. This also could cause the problem. Finally check the bass, treble balance and volume knob but turn them back and forth while unit is on and see if signal clears up momentarily. if this is the case the control knobs need to be cleaned. Also spin the connection jacks {RCAs} in the rear and see if this clears it up. If not you may have to have the unit serviced by a professional.

SOURCE: Speaker output

My unit does the same thing, I read online to install a RCA Patch cord from Main-In to Main Out and it worked.
I contacted Yamaha and they wanted to charge me to fix the issue and they will not fix it under warranty because I did not buy the unit from a authorized Yamaha dealer. Obviously a design flaw.

SOURCE: Setting up a Yamaha RX-V690 home theater system

you almost have the exact same situation i am in. i have the same receiver, and going to purchase a panasonic 50" (th50px75u). i think what i will be doing is running a hdmi from my hd cable box to my tv, and installing an audio cable (red/white) from my tv to the receiver. i believe there is an audio input below the hdmi insert. i have polk audio, but theyare about 10 years old, they sound great, but just too large....and may be purchasing a harman kardon system. which models do you have from polk? i have the rt16's, cs350ls center, and fx/500 rears. let me know what you have come up with as well...as it has been a while since you posted this.

cheers,
sean

SOURCE: Rear Surround speakers

Best thing to do is to put the unit in 5 channel or 7 channel mode. That will send left ch information to the front left and rear left speakers ( both will get the same information). Ditto with the right channel. The center channel will get centre channel information.

If all the speakers work, go out and rent TOP GUN. ( yes its old), BUT there are a few extreme scenes , one of which is the elevator scene, where the camera changes perspective and suddenly you hear the elevator doors close BEHIND you through only the surround speakers ( have the unit in surround mode....NOT 5 or 7 ch mode ). If this works ok, then you have no problems.

Remember, surround sound only produces information in the rear channels when the information is there. To check out the digital and DTS decoders, get an action flick. If you can, get a remote too, because that will unlock many features about the receiver that you cant get to with the front panel controls. Also go to yamaha and download the owners manual ( its free !!).....that should get you going.....

best of luck...

In my JVC RX 8SD only works a channel. How do I repair this defect?


Start with the simple things.
  • Check left right balance
  • Swap output speakers left to right
  • Swap the speakers at the receiver to make sure no wire open/short
  • Swap input RCA cables left to right red/white - white/red
Ok No JOY!
JVC has thermal overload circuits/overload on most of there Amps.

Remove power for a minute or two to see if there is a reset.

Rewire speaker connections to speaker set 2.

Connect REC out to Rec In swap cables and see if problem is in pre-amp or power amp.

Check internal fuses.

When I hook up the rear speakers to my in-wall speakers, I can't get any sound. I have speaker button 1 and 2 selected.


Hi:
you need to clear that you connect wall speakers for font,center or rear (surround) speakers?
Seem you connect for Front speaker.
Rear (surround) speaker will have "rear" mark on the back of your reveiver.
In general you need to select both buttons 1 & 2 then check your speaker wires connect into "output1" or "output 2" hint: each output will have 1 for left and 1 for right speaker. Each Left or right speaker will have 2 connection 1 red color (+) and 1 white color (-). Try to match these colors code for your speakers connection.

Have JVC 6008V A/V Receiver. No out-put from left-front speaker out terminals. Checked fuses, and all are good. R/F, and all other speaker out functions work fine.Switched speakers to make sure problem was...


make sure you're using the corresponding speaker inputs for speaker 1 (only) and turn off Speaker 2 on the bottom left corner near the headphone jack (it should be sticking out further then the speaker 1 button). hope this helps.

Rear speakers are dead, never got them to work. Changed front to back and rears work so speakers and wireing are good. Is it possible that because I did not hook up a center speaker this is the problem?


if its a 5.1 channels it means 2 front speakers,2 rear speakers or either the center speaker or the subwoofer.try to hook up either center speaker or subwoofer.

Rear speakers do not sound right they are working but sound muffled or something help??


Rear speakers in 5.1 are no more than sound reinforcement. The brunt of the work is done by the front left and right with most of the burden falling on the center channel.
