Question about Jensen JS1000-A Subwoofer

2 Answers

Subwoofer just stopped working. There's power but no sound.

I have a Jensen JS1000 Subwoofer. It was working fine for New Year's Eve and then the next day it wouldn't work. We use this subwoofer on a daily basis and never had a problem. The LED still turns on but there's no sound. Not even the slightest noise or vibration. I checked The Power plug, the phono plugs, and even opened up the back.There's no burning smell. nothing seems fried. The wires are all connected. The Speaker isn't damaged. I checked the fuse, it was fine but I still replaced it. Still no sound. Please help if you have any idea what this problem may be.

    I plugged the sound connectors and the humming noise doesn't go away, no sound comes from the subwoofer.

I have the same problem. My guess is that the subwoofer coil is messed up. You MIGHT have to get it recoiled. But before you do any of that get someone with a sub to play their sub in your car, if it works.... then your sub is messed up, if not.....then your amp is messed up ( trial and error ). Today i noticed my subs rubber surrounding is crooked, that may be the problem for me. Also when I press down on the sub it makes a sticking sound, like something came loose. So once i get everything opened and out ill let you all know the solution. Good Luck!

Why is my Jensen SPX-17 home entertainment subwoofer only putting out about 10% functioning base power volume level and loudness?

Gary, If you have the subwoofer open, what did you keep from measuring the voltage of both power supplies? And while measuring, why not put a load on both, and see what current they can handle?
When the error moves with one component (power supply) the error must be there. Without a multimeter, (I have several, but I'm not close to the power supplies) you can't tell if the power supply is working to full performance. So start there.
Just try to find out, if a part of the rectifier is defect (one diode) It won't be possible to point out what is wrong, if you can't measure on the device yourself.

No sound fuse good lite comes on

Chances are the main output semi-conductor has failed. It will be largest of the parts and might be on a heatsink. If it is an IC, 9 times out of 10, I would say it's gone.

Jensen JS1000-A sub stopped working, why?

Is is possible that the receiver's subwoofer configuration turned off? double check your speakers setup in the receiver...Just an idea.

Subwoofer not powering up

I could either be the sub or the main unit. The main unit actually sends a signal to the sub to turn it on so if that circuit is bad in the main unit the sub is never going to come on. I've also seen bad cables (You'd be amazed at how stubborn people can be when din connectors don't cooperate).
