Question about Yamaha YST-SW012 Subwoofer
My sub is turning on and getting full power but there is no sound coming out of it. We have checked the volume control on the unit as well as on the Yamaha receiver (receiver htr-6230). We have also just replaced the input cord (rocketfish 12 ft subwoofer cable, rf-g1214). If there are any troubleshooting tips or commonly known problems that I could try to fix I would love to do that and keep the original sub with my surround sound instead of completely replacing it.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

I too have amplifier and speakers thatI rent for parties, and sometimes when I connect them they don't work and I battle with them for hours before I find the out that its just a little thing that happened, like speaker wire might have cut inside, or the wire conneted for the CD to Amplifier is bad and son on.
But I will advice that you test your amplifier and woofer, with another equipment independently to be sure if they still working well or not. As this will help you to know what to do next.
May somthing happened to one of them the last time you used it and you did not notice, and it might just need some servicing.

Subs don't go to a variety of connections on the amp. Let's stop guessing and stick with the prescribed one. Register and download the manuals for free at retrevo.com Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.
See page E1 regarding placement and safety.
Page 44 - read about "humming".
If you have hum on the sub, is it there with and/or without the input cable attached?

SOURCE: No sound from my Yamaha
Feed it with an RCA cable any other audio device you may have (CD, TV, MP3 player, PC) to prove it can or can not woof. It will respond to any audio, not just LFE or subwoofer audio.
