I am sorry, if I had known before I would have told you that it was not the DIN plug or the control pod, you have a issue with the sgnal getting from your Subwoofer's internal amplifiers to the speakers, so  now you start the trouble shooting process, step one, unplug the 1/8 back behind the speaker that is not working properly and then plug the speaker that is working good into that channel with that cable, if it sounds good then the problem is your speaker itself or internal wiring. Cheap enough fix believe it or not. oops, gotta go, I may write more later.

 I think, after further testing, that I might have two problems. Here's why:

1. plug lead from R chan into L speaker (one w/o control pod) - sounds good.

2.  plug lead from R chan into R speaker (one with control pod) - sounds poor

3. plug lead from L chan into either speaker - poor/no sound at all

So I'm thinking I have a bad R satellite (could be the 1/8" plug, internal crossover, etc...) and some problem with the L chan of the subwoofer's internal amplifier (poor connection inside those spring-loaded terminals, the amp itself, etc...). Sound reasonable ?

After testing my computer speaker set up every which way to figure out why I had no R channel, I finally Googled "GMX A-2.1 + troubleshooting," found this forum, and BINGO!  My problem was a bent DIN plug pin.

Gotta LOVE the internet.  Thanks Amy!

Thanks to this forum ! I was ready to ship mine off for repair , then I came across this forum and was able to fix the problem myself ! Actually I had 2 problems , one was a bent pin on the din connector , the other was the big wire plug on the control pod . Refer to calvinj's post . It was excellent information ! I did notice that the pod was a little stubbon coming off , but a quick bump with a screwdriver handle did the trick ! Thanks SO much ! I LOVE the system just like I did before !

Both speakers "work" as I have switched the speaker wire and hear sound from both when I move balance control to one; the other of course then does not emit sound. (I also had another spare speaker and tried that too and speakers all "work").

The Pod on 1st speaker is new replacement from Klipsch that I put on last night.

I just bought a new sound card today and still have the same problem where one speaker does not emit sound. Since the Pod is new the connector pin to subwoofer is in mint condition.

I thought the sound card would have fixed the problem, but I still hear sound only from 1 speaker. Speaker wire seems ok. The mini jack plug seems ok.

The sound drivers are all new as they were downloaded today as I installed the new sound card.

I am using Windows XP SP3.

The balance is all the way right to try and test right speaker; I only hear muffled sound from the Subwoofer.

So:

1. Speakers work
2. Pod is new
3. Sound card is new

Any assistance would be appreciated. Thank you.

so, when you test it with another control pod they work fine? I am confused here. and FYI, just because a control pod is brand new does not mean that it works fine. I have done alot of replacement plugs on quote "New Control Pods". so it might be worth considering, and also, what did you do with your old control pod? I may be willing to buy it off of you if you still have it.

I wanted to see if the control Pod was the culprit so used a new one that Klipsch sent me; the pins look fine on both. I will save the other one as a back up Pod. I don't believe it is the Pod that is the problem nor the plug that goes into the subwoofer as the pins look mint and tight.

Could it be a bad fuse in the subwoofer or would it then not emit sound at all? How do you tell if the fuse is bad? The sound is muffled from subwoofer but is on and is active. But only one speaker will work at a time. Thank you.

Well, there are two fuses inside the subwoofer, one for the left channel and one for the right, but what I am not sure about is you said something like the sound changes as you change the pan on the soundcard? I do not recall exactly how it was put, but anyways, yes, there are 3 fuses in the 2.1 system, one is the main power fuse, which is located on the backside of the subwoofer with that little plastic slotted screw looking thing, and then if you take the back of the subwoofer plate off and pull it out you will see on the other side of where the speaker wires go in there will be 2 circuit boards their and one is for the left and one is for the right, each one has it's own fuse as well, I would certainly test them. you can test them with a simple voltage meter. Please let me know if there is anything else I can help you with.

Thank you.

I switched the speaker wire and mini plugs from the backs of speaker w/ Pod (L) and the right one speaker (R), The left one with Pod didn't work, but the right one did, so that eliminated a wire and speaker cause/problem. I also removed the wires from the subwoofer connectors and swapped them to also test the wire and connectors.

okay, well, if this was done properlly, And I am sure it was, then that means you have narrowed it down to the outputson the back of the subwoofer, leaving the 2 most likely causes being the fuse on that channel(hopefully) or a more serious problem on that channel, or 2 the preamp (control pod). I would start with testing that channel though with a voltage meter, also try measuring the resistance from one side of the fuse to the other if the fuse appears good at first, sometimes they can cut down the signal, not that I think this is likely, but it has happened before. and just see if the measurement are differant from one end to the other. checking for a blown fuse can usually be done without even having a voltage meter, usually you can see the break in the fuse. but just because you can't see it doesn't mean it isn't there.

Thank you.

I read in a thread somewhere on these forums that someone had a similar problem and it wound up being a bad internal amp inside the subwoofer. I will open the subwoofer and check the fuse. Would the internal fuses be the same part / type as the external one that is on the back side (that you can turn with a coin)?

I really have had bad luck with Klipsch products in the past 8 years or so I have gone through one 5.1 system and two 2.1 units. Their customer service and friendliness is great, but they need to have some ape-geeks come in and actually hard test the products.

If the internal fuses look ok then it is probably the internal amp of subwoofer and if that is the case I am going to get the highly rated Logitech Z 2300 system and never touch a Klipsch product ever again.

I opened the back unit (8 screws along edge) and replaced the fuses and the problem is still there.

No Way, the Logitechs do not touggch the Klipsch systems, Creative Gigaworks on the other hand.... Well, I don't feel right saying that stuff on here, but they are also excellent systems, but they are not cheap, then again, neither is Klipsch. If the amplifier for that side wnet bad it can also be repalced, not as easily, but it can certainly be done. and as far as the fuse goes, they are not like the one on the rear of the sub, they are the type that snap in and out, you will see.
