No sound from left speaker on right deck. left deck is fine. confused! tried unplugging one at a time and only the right plug is working. is there anything simple i can do to rectify this problem? as i'm not knowledgeable enough to start taking things apart! thanks in advance.

Hi,
Here's a solution to see if you have a problem with either your receiver or turntable.
The turntable has 2 RCA's one red for right channel, and one white or black for left channel, which plug into the back of the amplifier.

• Unplug both RCA from rear of amplifier.
• Plug in a cd or dvd player into those inputs on the amplifier, the sound will be lower but it will give you an indication if the amplifier is ok or not.
• If you have sound on both channels left and right then the amplifier is good
• If you still only have sound on left channel, then there is a problem with the right channel input on the amp.
  

• If your amp, is good, unplug the cd /dvd player.
• Put a record on and start playing the record
• Plug the white or black RCA from the turntable into the rear of the amplifier marked left, you should have sound.
• now unplug it from the left and plug in into the right red RCA socket, if you have sound the amplifier is working fine.
• if there is no sound there may be a problem with the stylus cartridge on the turntable
  
• now lets reverse the test
• unplug both RCA from amp.
• Plug the red RCA into the left socket on amplifier, if there is sound, turntable is working fine, if no sound there is a problem with either the stylus cartridge or that red RCA cable.
• now unplug the red RCA from the left side and plug it into the right side socket
  

• if there is no sound there may be a problem with the stylus cartridge or RCA cable.

I hope this helps

try swapping the speakers around if the problem still persists either the speaker is faulty or
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

in your system preferences click on sound and adjust the settings you need.

If you put the good channel from the deck into the right and then left phono imputs of your amp, the sound should come out from the left and right speakers. If it only comes out from the left, then the amp as a right hand channel fault. Now if other devices work on both channels, then it's the pre-amp for the phono socket that has a fault on it. You should be able to find this by following the wires from the phono socket. If you touch around that pre-amp you should get it to buzz on either channel (where it joins with the main pre-amp). Doing this with a screwdriver will pin-point where the faulty part is (working backwards). PS don't short anything by touching to bits of metal together with the screwdriver.
Magnetic cartridges need a small pre-amp before they can be past to the main pre-amp. That's why you can't hear anything with the deck plugged into another line socket.
If you get signal on both left and right speakers with the above test the deck is to blame.

Sort of sounds like there's a PC in the mix.

Can you swap the left and right speakers to isolate the speaker from the source as the problem?

Have you tried switching the various plugs around to isolate if anything comes out to the Left Channel, ever or if any other speaker plugged in as the Left works at all? Turn the volume down and bring it up slowly at first because if you send Subwoofer programming to a speaker not designed for it you may damage it.

If nothing works when plugged in as the Left speaker, maybe the sound card is the problem. Resubmit a question with the source or the PC as the problem

Well the jack you plug in has three surfaces. So when you pulled it part way out then the left speaker part of the plug came in contact with the right speaker contact inside the jack and it worked. Speakers are good so if you have checked your volume control in Windows and checked that the balance control is centered it could be that your sound card is defective. You didn't tell me what kind of computer you have and if the sound card is built into the motherboard or if it is an add on card. I don't know if you only have the Window's sound control in Control Panel or if your card has a seperate software for configuring your card but I think the only thing that might disable the left speaker has to be the balance control in Window's sound control or the seperate software.

Solution to having no sound coming from certain speakers in a 7.1 speaker setup for TX-SR606 receiver when playing a DVD.

Review the cable setup for the DVD player since it was identified as the source of the problem. Best to unplug and plug in the cables to ensure they contact the back of the receiver's RCA jacks. Redo the microphone setup for Audyssey 2EQ calibration. A good chance that it is the cable that may have caused the malfunction and loss of sound from the speakers. The cables can come loose during setup and not plugged all the way to the back of the RCA jacks or a defective cable causing signal loss.

try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.

I'm having this same problem and have sort of solved it with a really wierd technique I found at Logitech. Evidently this problem is related to the control pod rather then the RCA jack. Try this:

Unplug the control pod from the subwoofer Turn off the main switch Turn the volume knob one full turn, tap the knob Repeat again (2 times) Replug the control pod Turn on the main switch and the control pod See what happens

I found that this got the speaker working finicky after it was almost totally useless. It seems to be cutting out randomly, but fidgeting with the control pod or it's connector jack fixes it. No clue what the deal is here, but your problem is identical to mine so take some time to screw around with these components with music running so you can hear if it suddenly works.
