Having problems with your Logitech Z-680 Computer Speakers ?
Channel not working
\015 The Left Rear channel is out. I've tried the speaker on a different channel - it works fine. I isolated windows and my sound card by plugging in my MP3 player; nothing comes out of that channel.\015
If the Logitech Pulse 475 is the same as the Labtech Pulse 475 then the left channel amplifier probably blew. The Labtec uses a 5 pin TDA2030A, which costs around $3. You will need to know how to solder to repair this. The back of the case comes off by removing the 8 screws around the back of the case and lifting it out by the power cord. Then, simply desolder the left channel amplifier marked IC201 (it's on the leftmost side of the board, next to the volume potentiometer) and solder the new amplifier in it's place.
My guess is that there is an output failure on that particular speak channel. Take the unit in for service.
