I have a JVC home theater with a SP-PWM505 subwoofer. When i turn on the unit the green light on the subwoofer comes on for 2 or 3 seconds then goes off. I here the unit power on, but then it clicks off. The Video works but i have no sound from any speakers. Any idea of what the problem is?
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)
It is possible that the power supply, and or the internal amplifier has some components that have failed. The unit will have to be serviced.
Get in touch with JVC to find out if your unit is still under warranty, and to find out who is their authorised service rep for your area.

the sub woofer turns off as soon as i increase the volume
I have had this model for about 3 years now and just recently when I am watching a DVD or listening to a CD......anywhere from 5 minutes to whenever....the green light goes off on the sub-woofer and is off but the DVD video is still going. HELP!!!!!
It seems my SP-PWM505 clicks off (along with all my other speakers) if the volume is louder 20. It's really frustrating since it doesn't sound good until around 40-45. Help?
I have the exact same problem, could it be just the power cord from the subwoofer to the receiver?
That subwoofer is turn by the cd player, if the subwoofer is at fault, it will shut off
