Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Hi. I have a Klipsch sw-350 subwoofer and my problem is that it doesn't turn on. A fuse checked..and it checked out fine. Are there more then one fuse?


Only 1 fuse. Sound slide the auto turn on sensing circuit is out. Will need to be taken or sent for repair. Contact manufacturer for repair or replace the entire amp. Replace amps are available from sources like partsexpress.com

Klipsch sub 10 keeps blowing fuses


More than likely the power supply switching transistors have fried. Also check the large caps in the primary side of the power supply. If you don't know what your are doing do not attempt to fix the power supply.. very dangerous voltages involved !!! Send it to Klipsch for repair or purchase a Bash replacement panel http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-750

The power supply switching transistors are likely fried. Dangerous high voltages involved. I would remove the plate and send it to Klipsch for repair.

Klipsch Speakers 4.1 died suddenly


Humm. Plug some earphones or another set of speakers into the computer and see if you get sound. That will at least point you in the right direction. And not to insult your intelligence but make sure the speakers are plugged into the green port.
