Re: no power/no led

First you need to check the fuse which is right on the inside after you take off the back panel. I suggest you get someone with electronic experience to help you

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.

Electrical short in the subwoofer

You're quite right when a fuse blows there's a short. The short will be in either the power supply section, or the main amp. You will be looking for a semi-conductor of some sort. A multi meter on the ohm setting will track it down quick if it's a transistor. As the meter scale will be just like you have touched the probes together. Follow the circuit back from the fuse. Check any part that you suspect. If the sub uses an IC power amp, it could be a strong suspect!

Popping harman kardon subwoofer

Mine did the same thing all of a sudden. The problem is a AC mains detection circuit that seems to affect many previous HK sub models. The solution that worked for me was to replace capacitor C112 on the main pcb of the subwoofer amplifier. You need to remove it from the circuit board with a soldering gun and replace it with a higher rated capacitor. I used a 2u2 40v and the subwoofer is working perfectly again! :)

The subwoofer just quit working I don't know if i turned something off. I check the various levels and found one that said "sub woofer off/ on and switched it to "on" but it still doesn't work. any...

1) Check your power outet - make sure you have power.
2) Check the cord going to sub-woofer, check power strip if using one, we want to make sure you have power going to the subwoofer.
3) If so check to see if you have a fuse installed in the subwoofer, replace if needed.
4) Make sure your audio wires are attached to subwoofer, inspect audio wire, if it is old wire then replace.
5) Trace your wire back to your system make sure it is connected to the Subwoofer terminal.
6) Check your menu options on your audio system, make sure the subwoofer is enabled.

JBL TLX PS10 Subwoofer - Does not work

If you have checked the fuses which it sounds like you have, your amp may be out. Take that RCA and plug it into the other speaker. If thar she blows, treat as warranty and call the factory. If this is helpful, please post as such.

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

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!

Subwoofer - no sound

Had the same problem when mine first arrived. Unplug and replug the power cord at the back of the woofer. Worked for me!

No Power - LED not lit.

Open up the back of your gale 3080 and check the 2 fuses situated near the transformer.They look like 2 silver cylindrical shapes.Check that they have not blown if they have the will cost you around £2 to replace.Better than the 50 quid you will pay when you take it to your hi fi dealer to open up the back of it.
