Yamaha YST-SW320 subwoofer won't play sound

I bought a Yamaha YST-SW320 subwoofer along with a Yamaha amplifier, they worked fine for several years, just recently i've been using them to parties etc. The amplifier still works fine to my knowledge, but the subwoofer won't produce any sound. The power lights are on, but no sound. From memory it didn't just cut out when i was using it. Randomly it just didn't work when i went to use it one day. Any ideas or suggestions would be appreciated! Thanks James

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.

Best wishes

My subwoofer only works at a very low volume, even with the bass turned all the way up on the subwoofer and on my computer.

You might need to get a different sound card and/or an amplifier, as the sound card on your computer may not be pushing enough amps to the system.

No sound from my Yamaha YST-SW315 subwoofer. When I run the test speakers don't have sound either. Not sure if its the subwoofer or the Yamaha RX-V450 receiver

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.

I have a yamaha yst sw320 subwoofer connected to a yamaha dsp-a595a amp. I recently disconnected my equipment and when i reconnected it im getting a feedback hum/noise through the sub. I've tried...

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

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?

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.

I need the value of resistor 45. It is discolored and looks like either red white red or orange white orange. I think the tolerence is silver but not sure. Thanks, ae4qp The unit comes on but has no...

150 ohm, 1/4W. But the problem is in STK 404-070 power amplifier. If you change only resistor, it will burn again. Try to replace power amplifier and then resistor.

I have a YST-SW150 speaker that turns it self off after 7 minutes , turn it back on and it'll go again for 7 minutes, (sounds good those 7 min) music sensor auto on/off is off

I just fixed one of these with the same symptom.
In between the power supply board and the amplifier board are a number of rather fine interconnect wires. One of these is the shutdown/startup control line for the auto on/off function.
In my case the wire had been pinched where they are cable tied together. Causeing the power supply to think there was no music input and should shut down.
rejoing the broken wire rectified the problem.
In my case more than one wire had been damaged.
the shut down line is labled SO on the amplifier board connector.
