hi everyone,
My subwoofer yamaha (SW-P130 SubWoofer), just stopped working yesterday for some reason.
It's attatched to my Yamah htr 5630 av receiver (350) watts 70 per channel....and all my other speakers are working fine.
They are all yamaha as well...
The fronts are NS-555-3-Way-Reflex-Speakers, and all hooked up in 5.1 surround sound
I heard someone say the fuse on the subwoofer my be blown, but i don't see any fuse housing anywhere....

Help...! what is anybody's prognosis here?

When i run a speaker test they all work except my subwoofer.
Any help would be appreciated...

when you plug-up the sub does it make a sound? A thump, hiss, anything?
Does it have a "power" LED? If so, what color is it?
Hook it up to a regular speaker out at low volume. If it plays, the sub is OK,
if not, either a fuse is blown or the amp is OR a wire is loose inside. That would be your "luckiest"
problem, short of a bad cord. Remember to switch cords when testing the sub.

No sound when i plug it in at all nothing.
Yes "power led" is on - and it's GREEN !
Thanks so much for your recommendation Jeff the Lizard!! (Awesome name by the way) heheh.
I will try that recommendation!
How do i hook up a regular speaker to it? My yamaha receiver has a small rca plug for the subwoofer, i can't hook up traditional speaker thru that connection.
Hmmm....see my dillema? I'm between a rock and a hardplace with this thing..

actually you probably can. Usually the sub-out is just a mono signal, anyway. It may not sound good but if it sounds you know signal is passing thru. Hook the sub to another OUT on the amp to test it. It may be just one channel but you'll know if the sub-out signal is going to the sub. If when the sub is turned up fully you hear no hiss or noise whatsoever I'd suspect wiring inside the sub. Be sure to check cables first.

OK, I see, now. You want to test the sub-out signal. OK, you can use a meter or hook, say, an old cassette deck up to that output, set it to record and watch the meters. If one moves when the receiver is playing, then signal is "flowing". The only other way is to borrow a sub. BUT a simple meter set to below 1 amp DC should do it.

Make sure all of the switches are set properly, it's too easy to accidently change settings when moving components around. Here is a link to the manual for your components.....

Good Luck

Double check your crossover settings. Your sub may have a crossover in it, or your receiver might, or both. If your main speakers are capable of handling a lot of lows, and your crossover is adjusted to suit them, your sub might not go a lot lower than your mains, and the lows from your sub might not seem as pronounced. Some subs adjust themselves in this regard, and if yours did that, it might seem that it just stopped working. It sounds too easy to work, but I'd spend some quality time with your manuals before tearing into your sub. If nothing else, the manual will tell you if your sub has a fuse, and if so, where to locate it.
