Some possibilities (your description suggests that both speakers are okay):

- a desoldered pin on the left speaker connector inside your unit or a damaged connector

- a fault or a desoldered contact on one or more components in the left channel's preamp or final amp section, or at the power supply section for that channel, also check speaker protector fuses on the board, if there are any

- a bad connector contact somewhere on the board, possibly an oxydized contact, desoldered pin or a (partially) disconnected/broken wire.

Anyway, these are just a few suggestions, but i hope they can help somewhat...

No volume on all left side speakers


Determining the Cause of the Problem Let's assume our system has a head unit, a crossover, a two channel amplifier and two door speakers with only the right speaker working (the left speaker is not working). If the door speakers are behind the door panels then we want to make sure the speaker is the problem before removing the panel. We'll work backwards starting with the amplifier and ending at the head unit. Testing for a Speaker Problem With the vehicle and the stereo turned off disconnect the speaker wires for both the left and right speakers at the amplifier. Now connect the left speaker to the right amplifier output (which we know works). Turn on the stereo system and make sure the balance is set to the middle position.If the speaker still doesn't work then the problem is somewhere between the amplifier and the speaker Testing for an Amplifier Problem Now we'll need to see if the amplifier channel is bad. Put the left speaker back on the left amplifier channel and the right speaker on the right amplifier channel. This returns the speaker wiring to its original configuration. Again, with the vehicle and stereo off unplug the RCA cables from the amplifier's input and switch them so the left cable is in the right input and vice versa. Turn on the stereo system. Testing for an RCA Cable Problem For any intermediate components between the amplifier and the head unit follow these steps for each one. We only have a crossover so we'll just do this once. Begin by testing the RCA cables between the intermediate component and the amplifier. Unplug both RCA cables from the intermediate component's output. Now plug the working channel's RCA cable into the non-working side of the crossover. In our case the working channel is the right so plug the right RCA cable from the amplifier into the left side of the crossover. Turn on the stereo system.
If the right channel continues to work then you know the problem is in the RCA cables between the amp and the crossover. esting for a Crossover or Equalizer Problem At the input of the intermediate component (in our case the crossover) flip the RCA cables around (left to right input and vice versa). Turn on the stereo system.
If the right channel continues to work and the left channel continues to not work then you know the problem is in the intermediate component. Replace or repair this component.
If the problem is now in the right speaker and the left speaker works then the problem lies before the crossover. Turn off the stereo system and return the RCA cables to their normal places.
Testing for a Head Unit or RCA Cable Problem Pull out the head unit from the dash so you can access the RCA cables. Unplug both RCA cables from the head unit. Do not disconnect any other wiring. Plug the right RCA cable into the left channel of the head unit. Turn on the stereo system.

I'M TRYING TO CONNECT MY MMS 321 PHILIPS COMPUTER SPEAKERS TO MY 32 in LG TV CAN YOU HELP ?


Hi Richard,
Connecting the speakers tot he LG Tv is fairly simple.. Connect the audio cable from the speakers to the headphone jack on the TV. The headphone jack will be either on the left or right side of your TV depending upon the model number.

I'm attaching the user manual for the speakers for your reference

Adding Spaekers


If it's an original 321 system (series 1) then it has an audio output on the back. (via RCA jacks) You would still need an amp or receiver to connect the speakers to.. (unless they're powered speakers)
If it's a 321 series II or 321 series III- it does not have an audio output.
If the system has a DVD tray right in the middle of the media center, then it's a series 1.
Otherwise, you'd have to get a 1/8 splitter to come from your Mac's headphone output. (still- you will need an amp/receiver or powered speakers to have both 'rooms' playing the same thing from your computer)

Strange problems with Z-2300's


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.

Left speaker doesnt work


i've got the same speakers & have noticed that depending on the type and quality of the device that i plug them into i'll sometimes only get sound from the right speaker. i've deduced that this is due to the type of output the device offers. for example, if i plug the green tip of the cord into the headphone jack of a television with only one speaker only the right speaker will work. hope this helps

Only one surround back speaker works


It sounds to me like one of your speakers may be mis-wired. Try reversing the speaker wire (don't switch right-for left, but switch negative for positive) and see if that changes anything.
