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
other than that you might have a warranty issue
hope this helps

I plugged my Logitech Z623 (110V) into a 220V output. Made a 'pop' noise and now it doesn't work. What parts need replacing and how would I do this?


Take unit apart an look at power supply. It could be just the solid state fuse popped. Power supplys are not hared to repair, the diodes are about .50 a piece, the caps about $1 a piece or so. Hopefully ot did not reach the speaker, an i doubt it did.

Subwoofer makes noise like an untuned TV regardless of volume knob


I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

A gift was just given to me. They are the Logitech Z623 speakers. But, they came with no documentation. When I plug them in as intended with either my HDTV or my desktop pc, only one of the satellite...


I checked Logitech's website and they don;t have any downloadable documentation for this product. Anyway, let's just try and fix it.

First, make sure your left and right speakers are connected properly to the bass speaker.

Next, the wire from the bass should be connected to your soundcard's line out port (light green) or into your TV's audio lineout.

You can also adjust the volume of your bass separately on the right speaker.

Update me if this worked or if you are still having trouble.

Thanks for using Fixya!

Only one small speaker is working, it works from left or right outlet, bass isn't working and the other small speaker isn't working. What could be wrong


Your main board located inside the sub woofer that controls and separates the sound
has lost it's ability to switch the sound. You will either have to buy a new speaker system or call the manufacturer to see where a service center for you speaker unit is near you for repair.
This also can be a bad volume control knob either way it will need to be serviced.

Logitech S500 Volume Knob Broken


The simplest thing to try is some compressed air directed to the knob. This would clear out any dust or dirt that may be obstructing the knob. I am not sure what you mean by power cut so I am shooting in the dark here. If you mean a power surge that caused the volume to quit working then I would suggest an external volume control such as http://www.amazon.com/Koss-155954-VC20-Volume-Control/dp/B00001P4XH/ref=pd_bbs_2/002-2257004-6895258?ie=UTF8&s=electronics&qid=1194009359&sr=8-2
