Indicator light not working and humming noise

I have a Kenwood 103sw powered subwoofer that has a constant humming or buzzing noise when turned on. Noise does not increase or decrease with volume. Noise stops when rca inputs are disconnected. I tried two different receivers but problem persists. Also the indicator light for the mode does not come on when switched to movie mode eventhough the music mode light goes dimmer.

Could it be solved by reversing the AC Plug on this device, matching the other inputs? Hope your board is not blown.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Subwoofer is hummig what is this noise


Hum is a constant low-frequency buzz, usually at about 60 Hz or 120 Hz, which results from voltage differences between true "ground" (what you'd get shoving a copper pipe into the ground) and the electrical "ground" of your receiver's chassis When this voltage differential exists, it's called a "ground loop," and the hum it produces is darned annoying. You'll hear the hum mainly from the subwoofer because it's a low-frequency noise, you will need a ground loop insulator they are about $20 at any electronic store

Subwoofer inop


The blue power light merely indicates that house power is getting to the sub. My guess is that the internal power supply reacted poorly to the on-again-off-again power application and something failed

My subwoofer constantly makes a steady intermittent buzz sound while plugged in, even while powered off.


If it has a 3 prong plug, try a 3 prong adaptor - where only 2 prongs are plugged in. Sub's should not be grounded. If it still makes a hum noise, the amp circuitry may be compromised. Replace the amp with an equal at www.partsexpress.com

What kind speaker use my kenwood powered subwoofer 103SW


It uses a 10 inch, 4 ohm speaker, probably rated at 100 watts. If you are getting no sound, check your connections. Or, the subwoofer amp may be blown.

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

100watt sub


There is a problem wwith teh power supply or the amp section. Does the noise remain constant or does it vary in volume? The sub should have a level control, does the noise vary with that control?

Subwoofer has a constant vibrating tone that will not go away


I suspect that what you are hearing is the 60 cps of the mains. If the humming sound is coming the subwoofer itself, then it is possible that you have a defective/leaky capacitor in the power supply section of the subwoofer. In the subwoofer, if the buzzing sound is coming from anywhere else other than the speaker itself, then it is possible that you have a loose transformer again in the power supply. Unless you are comfortable working with testers and soldering irons, I would suggest an electronics technician who should be able to diagnose and fix it for you.
