Question about Aiwa NSX-DS55 CD Shelf System

No sound from left rear surround speaker

I've recently noticed that I get no sound from my left surround speaker. The right speaker functions normally.

The left surround has a faint hiss to it if I put my ear up to it, and if I swap speakers, that speaker works fine on other channels, and other speakers produce no sound (except for the faint hiss) when used on the left surround channel. So the speaker works, and is at least getting some sort of signal if it has the faint hiss (same as all other speakers when not playing anything)

I've tried all the modes I can think of and played with volume and balance. I've done the speaker test where it goes from speaker to speaker making a static noise so you know they work (all do, aside from left surround), and Dolby setups on DVDs produce the same result.

If anyone somehow knows a fix for this, I'd love to hear it.

Mp3 sound doesnt sound right

The right speaker is open, a digital meter set to ohms will confirm, good/bad should measure 4.0 ohms to 8.0 ohms, if no reading it is bad.

My rca rs 1289 5- cd changer mini system will not play, open, close, or change cds. how can i fix this problem at home?

Remove the case screws on the left and right side panels. Pay attention to the long screws that come out of the middle of the panels to make sure they get back in the right spot. Remove one screw from the top rear back panel. Lift side panels of in a hinged motion from the bottom. Remove the top panel in a hinged motion from the rear. In the center of the disc tray remove 1 screw from center. Note the orientation of the tray for re-insertion. Lift the tray up and out. look for small dc motor and spindle. this motor is used to spin the tray. You should find a black belt2_bing.gif between motor and spindle. Make sure it is in good condition. Look to the right rear of the unit. there is a second motor and belt which drives the tray. This belt may be broken or off its spindle. repair or replace the belt as necessary. Plug the unit in and test the open/close function and ensure the gear train, belts2_bing.gif and carriage move smoothly. reassemble.

The Graphic Equalizer pattern control is not working correctly - I can hardly hear the vocal on my CD's when playing even though I've selected vocal. Vocals are outplayed by background music.

That sounds more like a polarity, or phase problem. Make sure your speakers are hooked up correctly, with the correct colors going to (+) positive, and (-) negative. Make sure your rca connection are correct, and that every connection has a left and a right. No stereo-to-mono adapters.

Is setting to "vocal" an eq selection, or a "dolby" stereo selection?

Are you using a dolby surround stereo receiver with left, right, center, rear, etc.?? If so, try turning off any effects, or anything that would send signal to the center speaker.

Lastly, depending on what the source of your music is, it is possible if your connections or receiver settings are not correct...that the music upon playback will be out of polarity, meaning the vocal portion will cancel out. Combining left and right signal together can sometimes do this as well.

No sound from Rear Speakers

Ok, so we know the connections are correct, the speakers all work properly.

The only other thing I can think of is: is your PC actually sending signal to the rear speakers? Have you set it to 5.1 surround, and are you playing something in surround sound? The best way of checking (personal preference) is use some kind of racing game, reverse into something and you'll get a broken window effect in the rear speakers.

So, check to see if your PC is sending the rear effects, double check to make sure the actual speakers work (you could plug an MP3 player into the rear speaker input.

If this doesn't help, feel free to reply.

sorry but start with the obvious..the surround speakers usually are a looped curcuit using one single live split .so check each speaker works the cable is ok .if all checks out ok go for the selector switch if its a push switch press it repeatedly .if all this fails tap around the unit there might be a dry joint.good luck .farr64

Low Volume from right speaker of entertainment center - turntable only

Hi There thanks for your very good desctiption of the problem it really helps to have a lot of detail...

There are Mono and stereo types of stylis cartridges and it sounds like you have a mono equipped into a stereo amplifier..

If there are 4 small coloured wires visible under the stylis then
its a stereo stylis and should work, have a close look and maybe one of the small wires has dropped of the small pins on the back opf the stylis cartridge.

If there only two wires visible then its a mono cartridge and this is why you only have sound from one channel..

So answer is wires dropped of the stylis.
Wrong type of stylis cartridge.
if there are four wires and thay all look connected then perhaps the stylis is faulty and you need to replace it...

Cheers from YU BEUT
