Speaker left channel? must be broken as both speakers are still working on right input (channel, not sure if this is the terminology?)
Have you tried isolating the problem to see what exactly the problem is? First I suggest disconnecting the left speaker from the system and test the speaker by it's self. If you have any technical knowledge and an ohm meter, you can connect an ohm meter to the two wires comming from the speaker and see if you get 8 ohms or less. You SHOULD see something in the neighborhood of 8 ohms of resistance if the speaker is good. If you're not a techy and want a simpler "go/no-go" test on the speaker, then take the two wires going into the back of the speaker and BRIEFLY touch them to the two terminals of a 9 volt battery. If the speaker is good, you will hear a "pop" in the speaker as the battery connects. Again, ONLY BRIEFLY touch them. DO NOT connect them to the battery and allow them to stay on for more than about a half second or so, else you run the risk of burning up the voice coil in your woofers.
If the left speaker passes the test, then let's look at the receiver unit. I am not familiar with this particular make and model, but I dare say it should have multiple inputs. Just to be extra certain that the speaker wasn't somehow the problem, go ahead and connect the right speaker to the left channel and let's test the left channel of the receiver. Try using the various inputs on the receiver (i.e. am/fm, CD in, AUX in, Video in, what ever it may have).. Does the left channel yield ANY sound at all under any conditions?
If I'm not mistaken, the system has a separate power amp and receiver unit. Try putting a signal into the aux inputs of the power amp it's self using an RCA cable. You can connect the other end of the RCA cable to most any other CD player, or you can usually touch your finger to the center conductor on the RCA cable and listen for a buzz or click in the left speaker output. If it doesn't give any sound, then the problem is most likely in your amplifier. If it does give you sound, then we need to look at the receiver.
Something else I just noticed about this particular unit you have, is that it uses a ribbon cable to connect the receiver to the amplifier unit. I would suggest that if the amplifier checks good, then try replacing this ribbon cable with another one. You may have to have one specially made, or you may be able to order one. I hope that helps.
