It's likely that the amp module is damaged and will need to be repaired or replaced. If it's under warranty, the repair will be at no charge to you.

I had the same problem and it turned out that the directions are very unclear. You need to not only press the ID/SET button on the wireless system, but also on the wireless subwoofer itself. That solved my problem.

I fixed my subwoofer. The resistor at R16 (right next to the fuse) was the fried component. I removed it and replaced it with a 13K ohm 5 watt metal oxide resistor (from Mouser Electronics if not available locally). Works fine now. I got the solution and the circuit schematic from an audio hobbiest at diyAudio.com. This is, evidently, a fairly common problem.

The F61 indicates a problem detected in the output amp stage and the unit us shutdown to prevent further damage. If you can supply the model number, I can give you the part required and the approximate cost.

Well i had exactly the same problem, my sub turned off right away when i turned the whole thing on. Well i opened the subwoofer and was trying to find out something unusual, i took out, i believe, internal amp, well, whatever that thing is, under the lid. Which one is screwed with 6 copper screws, so you unscrew those screws, lift that lid and that whole board comes out. On that board i find something like burn around one of the parts.
you can see it in the pick, the part q2902, then i contacted JVC. At the beginning they said i need to take the whole thing to service center and so on. But later i made them to tell me what kind of part that is, so here :http://www.jvcservice.com/store/ProductDetail.asp?Part=KTC3199/GL/-T
bought soldering gun in home depot for $15, returned after i was done. And that is it, just have to replace it, but total cost only $12 ($5 part +$7 shipping)

you need to have service manual copy to check amplifier output section as it seems defective. There are few websites that offers service manuals download for small fee.
