    Ok, I was able to get a schematic for the skw-530. But the schematic doesn't give me what the voltage coming out of the linear transformer that feeds the ciruit board. There a two resistors that are connected to the transformer that get really really hot. the printed circuit board where the transfor connects does say "AC in". My question is what should be the proper voltage to the circuit board?

It's possible that you have accidentally switched off the sub-woofer outputs on the receivers. Onkyo have a speaker set up test. You should run that and see if the speakers are on and that a signal is getting through to them.

sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty

Subwoofer issues


Hi,

The fuse blows when the current that passes through it are beyond its rating. This could be brought about by excessive consumption of the load, in this case the amplifier powering the sub-woofer.

Repairs would involve component level and require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron. Often it is just the finals that needs to be replaced. Of course we cannot discount the possibility of other components or section such as the power supply.

The smoke indicates something heating up such as a resistor or diode or a capacitor.

Should you be uncomfortable opening the unit and doing a DIY (do-it-yourself), then perhaps you need to seek the services of a qualified professional.

Should the downtime and cost of repair be no longer economically reasonable, purchase of a new unit might save you further trouble.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Onkyo subwoofer not working


I fixed my subwoofer. The resistor at R16 (right next to the fuse) was the fried component. I removed it and replaced it with a 13K ohm 5 watt metal oxide resistor (from Mouser Electronics if not available locally). Works fine now. I got the solution and the circuit schematic from an audio hobbiest at diyAudio.com. This is, evidently, a fairly common problem.
