I have an onkyo ht-r530 and the subwoofer stopped working one day when i was listening loud. I can get sound to come out of the sub with a different reciever, but not my ht-r530. is there a subwoofer fuse that may be replaced inside the reciever? any reply at all would be very welcome. i would much prefer to fix it myself. Thanks in advance, Zach M
Turn the out put leval down on your sub, End the reciever, I was turn up to high,End that will cause it to cut out.

no, your output transistors maybe 2 of them are gone or the small power supply that feeds the other circuitry has become defective.

You might try this replacement

May not necessarily be the out put, discontect the sub from the receiver and see if it still makes a hum, Making sure that you turn auto on, off on the sub woffer.
If it still makes a hum, then you have a earthing problem, you can get a earth filter put on your internal wiring in your home, or you can remove the earth pin on your sub woffer

I would not suggest hooking up powered speakers to your receiver. Only if unit has sub woofer output can you hook up powered speaker

Also, it could possibly the preout terminal itself that is not working. One way to prove that is by transferring the subwoofer cable from the preout and temporarily transfer it to the tape out section. If it ouputs sound from there, then that means the speaker and the cables are working fine and it's just the preout terminal itself that is not picking up anything. ^_^
