Sorry, once there is short circuit happened in one of the component of a set devices mainly your surround sounds speakers and since they are all interconnected of there will be a chain reaction, one short circuit runs through the other device and then another short circuit will happen.

To make it short, if your speakers still have a warranty contact the manufacturer for support and most probably parts replacements.

If all else fails, purchase a new one...

Please never forget that on all electrical and electronic devices, especially home appliances, NEVER PULL OUT THE PLUG IF ITS TURNED ON, TURN IT OFF FIRST.

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.
